      1、设计数据库:设计好表结构,最好符合3NF,采用Hibernate tools将设计好的表自动生成对应的实体entity。 

         1、创建Maven项目,按需映入Maven包依赖。

         2、搭建Spring:配置Spring对控件层Bean的注入。

         3、搭建Hibernate:配置数据源,配置SessionFactory,配置事务,以及二级缓存ehcache的配置。

         4、测试Spring+Hibernate的框架搭建,写单元测试JUnit,测试事务配置等。

         5、映入SpringMVC:配置SpringMVC配置信息。

         6、配置web.xml容器

         7、测试三个框架的整合:Maven编译打包部署服务器,测试。

    1、数据库设计

    2、创建Maven项目,编写pom.xml文件

     pom.xml文件内容如下:  如果war错误,可能是缺少 web.xml 文件,如果文件头异常,(检查相关maven配置)

    </build>
    </project>

    3、引入Spring配置 

        编写配置文件,配置文件放在src/main/resources资源目录下(下同)。

       项目所需的配置信息config.properties

    jdbc.driver = com.mysql.jdbc.Driver
    jdbc.url = jdbc:mysql://192.168.178.60:3306/demo?useUnicode=true&characterEncoding=utf-8
    jdbc.username = root
    jdbc.password = 123456

    #hibernate config
    hibernate.dialect = org.hibernate.dialect.MySQLDialect
    hibernate.show_sql = true
    hibernate.format_sql = false
    hibernate.hbm2ddl.auto = update
    hibernate.cache.use_second_level_cache = true
    hibernate.cache.use_query_cache = true
    hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
    hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

    3.1、spring配置

    spring.xml的配置文件如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-4.1.xsd">
    <!-- 加载配置文件 -->

    <context:property-placeholder location="classpath:config.properties"/>
    <!-- 扫描service自动注入为bean -->
    <context:component-scan base-package="com.service.impl,com.dao.impl" />

    </beans>

    上面spring配置了对应包下组件bean自动注入管理,我们需要将dao,service的实现类交由spring管理,如(@Repository,@Service)。

    3.2、引入日志文件配置Log4j

      log4j.properties的配置文件如下:

    log4j.rootLogger = INFO , C , D , E

    ### console ###
    log4j.appender.C = org.apache.log4j.ConsoleAppender
    log4j.appender.C.Target = System.out
    log4j.appender.C.layout = org.apache.log4j.PatternLayout
    log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

    ### log file ###
    log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log
    log4j.appender.D.Append = true
    log4j.appender.D.Threshold = INFO
    log4j.appender.D.layout = org.apache.log4j.PatternLayout
    log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

    ### exception ###
    log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log
    log4j.appender.E.Append = true
    log4j.appender.E.Threshold = ERROR
    log4j.appender.E.layout = org.apache.log4j.PatternLayout
    log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

    4、Hibernate配置

          Hibernate的配置主要包括:配置数据源c3p0,配置SessionFactory,配置事务管理器,配置事务管理,其spring-hibernate.xml文件如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

    <!-- 配置数据源 c3p0 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
    destroy-method="close">
    <property name="driverClass" value="${jdbc.driver}" />
    <property name="jdbcUrl" value="${jdbc.url}" />
    <property name="user" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />

    <!-- 请求超时时间 -->
    <property name="checkoutTimeout" value="30000" />
    <!-- 每60秒检查所有连接池中的空闲连接。默认值: 0,不检查 -->
    <property name="idleConnectionTestPeriod" value="30" />
    <!-- 连接数据库连接池最大空闲时间 -->
    <property name="maxIdleTime" value="30" />
    <!-- 连接池初始化连接数 -->
    <property name="initialPoolSize" value="5" />
    <property name="minPoolSize" value="5" />
    <property name="maxPoolSize" value="20" />
    <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
    <property name="acquireIncrement" value="5" />
    </bean>

    <!-- 配置hibernate的SessionFactory -->
    <bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <!-- 注入数据源 相关信息看源码 -->
    <property name="dataSource" ref="dataSource" />
    <!-- hibernate配置信息 -->
    <property name="hibernateProperties">
    <props>
    <prop key="hibernate.dialect">${hibernate.dialect}</prop>
    <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
    <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
    <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

    <!-- 开启二级缓存 ehcache -->
    <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>
    <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
    <prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop>
    <prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}
    </prop>
    </props>
    </property>
    <!-- 扫描hibernate注解配置的entity -->
    <property name="packagesToScan" value="com.entity" />
    </bean>

    <!-- 配置事务管理器 -->
    <bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <!-- 配置事务增强处理Bean,指定事务管理器 -->
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
    <!-- 配置详细事务处理语义 -->
    <tx:attributes>
    <tx:method name="insert*" propagation="REQUIRED" />
    <tx:method name="update*" propagation="REQUIRED" />
    <tx:method name="delete*" propagation="REQUIRED" />

    <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
    <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
    <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
    <tx:method name="load*" propagation="SUPPORTS" read-only="true" />

    <!-- 其他采用默认事务方式 -->
    <tx:method name="*" />

    </tx:attributes>
    </tx:advice>

    <!-- Spring aop事务管理 -->
    <aop:config>
    <!-- 配置切入点 -->
    <aop:pointcut id="transactionPointcut"
    expression="execution(* com.service..*Impl.*(..))" />
    <!-- 指定在txAdvice切入点应用txAdvice事务增强处理 -->
    <aop:advisor pointcut-ref="transactionPointcut"
    advice-ref="transactionAdvice" />
    </aop:config>

    </beans>

    上面配置了二级缓存,ehcache,相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置,下面是二级缓存的配置。

    4.1、ehcache.xml的配置

    <?xml version="1.0" encoding="UTF-8"?>
    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
    <diskStore path="D:/ehcache" />
    <!-- DefaultCache setting. -->
    <defaultCache
    maxElementsInMemory="1000"
    eternal="false"
    timeToIdleSeconds="120"
    timeToLiveSeconds="120"
    maxElementsOnDisk="1000000"
    overflowToDisk="true"
    memoryStoreEvictionPolicy="LRU">

    </defaultCache>

    <!-- Special objects setting. -->

    <cache
    name="org.andy.work.entity.AcctUser"
    maxElementsInMemory="2"
    memoryStoreEvictionPolicy="LRU"
    eternal="true"
    diskPersistent="false"
    overflowToDisk="false"
    maxElementsOnDisk="1000000" />

    </ehcache>

     上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

    5、生成业务entity实体

          设计好数据表后,Hibernate的实体有工具Hibernate tools自动生成,Eclipse需要安装Hibernate tools插件(我在线安装过几次都不成功,推荐使用links离线安装,附录将介绍),所以不需要手工的书写,下面就贴一个用户信息的实体,AcctUser.java

    package com.entity;

    import java.util.Date;

    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    import javax.persistence.Table;
    import javax.persistence.Temporal;
    import javax.persistence.TemporalType;

    import org.hibernate.annotations.Cache;
    import org.hibernate.annotations.CacheConcurrencyStrategy;

    /**
    * AcctUser generated by hbm2java
    */
    @Entity
    @Table(name = "acct_user")
    @Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
    public class AcctUser implements java.io.Serializable {

    /**
    *
    */
    private static final long serialVersionUID = 6980093847795726310L;

    private String id;
    private String nickName;
    private String telephone;
    private Date registerTime;

    public AcctUser() {

    }

    public AcctUser(String id, String nickName) {
    this.id = id;
    this.nickName = nickName;
    }

    @Id
    @Column(name = "id", unique = true, nullable = false, length = 36)
    public String getId() {
    return this.id;
    }

    public void setId(String id) {
    this.id = id;
    }

    @Column(name = "nick_name", nullable = false)
    public String getNickName() {
    return this.nickName;
    }

    public void setNickName(String nickName) {
    this.nickName = nickName;
    }

    @Column(name = "telephone")
    public String getTelephone() {
    return this.telephone;
    }

    public void setTelephone(String telephone) {
    this.telephone = telephone;
    }

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "register_time", length = 19)
    public Date getRegisterTime() {
    return this.registerTime;
    }

    public void setRegisterTime(Date registerTime) {
    this.registerTime = registerTime;
    }

    }

    6、创建Dao层  

         接口自己处理

    package com.dao.impl;

    import java.util.List;


    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Repository;

    import com.dao.UserDao;
    import com.entity.AcctUser;
    @Repository("userDao")
    public class UserDaoImpl implements UserDao {
    @Autowired
    private SessionFactory sessionFactory;

    private Session getCurrentSession() {
    return this.sessionFactory.getCurrentSession();
    }

    public AcctUser load(String id) {
    return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);
    }

    public AcctUser get(String id) {
    return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);
    }

    @SuppressWarnings("unchecked")
    public List<AcctUser> findAll() {
    List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();
    return acctUsers;
    }

    public void delete(String id) {
    AcctUser entity = this.load(id);
    this.getCurrentSession().delete(entity);
    }


    public void flush() {
    this.getCurrentSession().flush();

    }

    public String save(AcctUser entity) {
    return (String) this.getCurrentSession().save(entity);
    }

    }

    7、创建Service层

    package com.service.impl;

    import java.util.List;


    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;

    import com.dao.UserDao;
    import com.entity.AcctUser;
    import com.service.UserService;

    @Service("userService")
    public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    public AcctUser load(String id) {
    return userDao.load(id);
    }

    public AcctUser get(String id) {
    return userDao.get(id);
    }

    public List<AcctUser> findAll() {
    return userDao.findAll();
    }

    public void delete(String id) {
    userDao.delete(id);
    }

    public void flush() {
    userDao.flush();
    }

    public String save(AcctUser entity) {
    return userDao.save(entity);
    }

    }

    8、测试Spring和Hibernate的整合

     我们可以在src/test/java编写测试类,测试上面的配置,如果测试成功已经基本大功告成。

    package springmvc_hibernate_demo;

    import java.util.Date;
    import java.util.UUID;

    import org.apache.log4j.Logger;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

    import com.alibaba.fastjson.JSON;

    import com.entity.AcctUser;
    import com.service.UserService;

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = { "classpath:spring.xml",
    "classpath:spring-hibernate.xml" })
    public class TestUserService {
    private static final Logger LOGGER = Logger
    .getLogger(TestUserService.class);
    @Autowired
    private UserService userService;

    @Test
    public void save() {
    AcctUser acctUser = new AcctUser();
    acctUser.setId(UUID.randomUUID().toString());
    acctUser.setNickName("andy");
    acctUser.setRegisterTime(new Date());
    acctUser.setTelephone("13022221111");
    String id = userService.save(acctUser);
    LOGGER.info(JSON.toJSONString(id));
    }
    }

    9、引入SpringMVC

         添加spring-mvc.xml文件

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-4.1.xsd

    http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    <!-- 自动扫描@Controller注入为bean -->
    <context:component-scan base-package="com.controller" />

    <!-- 以下为SpringMVC配置 -->
    <mvc:annotation-driven>
    <!-- 返回json数据,@response使用 -->
    <mvc:message-converters register-defaults="true">
    <bean
    class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="supportedMediaTypes">
    <list>
    <value>text/html;charset=UTF-8</value>
    <value>application/json;charset=UTF-8</value>
    </list>
    </property>

    </bean>
    </mvc:message-converters>
    </mvc:annotation-driven>

    <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 -->
    <bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
    value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/views" />
    <property name="suffix" value=".jsp" />
    </bean>

    </beans>

       上面配置了包扫描Controller,[email protected]��,和视图层的配置。

    10、配置web.xml容器

          web容器是web项目的大脑,所以web容器,首先需要引入spring,让spring管理各个框架,并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

    web.xml文件如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
    <display-name>springmvc_hibernate_demo</display-name>

    <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
    </context-param>

    <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
    <param-name>encoding</param-name>
    <param-value>utf-8</param-value>
    </init-param>
    <init-param>
    <param-name>forceEncoding</param-name>
    <param-value>true</param-value>
    </init-param>
    </filter>
    <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- openSessionInView配置 作用是延迟session关闭到view层 -->
    <filter>
    <filter-name>openSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
    <init-param>
    <param-name>singleSession</param-name>
    <param-value>true</param-value>
    </init-param>
    </filter>

    <!-- 监听servletContext,启动contextConfigLocation中的spring配置信息 -->
    <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 防止spring内存溢出监听器 -->
    <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>

    <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
    <param-name>contextConfigLocation</param-name>
    <!-- 此处配置的是SpringMVC的配置文件 -->
    <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>*.htmls</url-pattern>
    </servlet-mapping>

    <filter-mapping>
    <filter-name>openSessionInViewFilter</filter-name>
    <url-pattern>*.htmls</url-pattern>
    </filter-mapping>

    <!-- 配置session超时时间,单位分钟 -->
    <session-config>
    <session-timeout>30</session-timeout>
    </session-config>


    <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
    </web-app>

    11、创建控制层Controller

         控制层UserController

    package com.controller;

    import java.util.List;

    import org.apache.log4j.Logger;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.ModelMap;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;

    import com.entity.AcctUser;
    import com.service.UserService;
    @Controller
    public class UserController {

    private static final Logger LOGGER = Logger.getLogger(UserController.class);

    @Autowired
    private UserService userService;

    @RequestMapping("/showInfo/{userId}")
    public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
    LOGGER.info("查询用户:" + userId);
    AcctUser userInfo = userService.load(userId);
    modelMap.addAttribute("userInfo", userInfo);
    return "/user/showInfo";
    }

    @RequestMapping("/showInfos")
    public @ResponseBody List<AcctUser> showUserInfos(){
    LOGGER.info("查询用户全部用户");
    List<AcctUser> userInfos = userService.findAll();
    return userInfos;
    }
    }

    接下来。访问测试咯!!!!只是简单记录下,可能有些没有考虑周全
