SpringMVC+Spring+Hibernate整合开发

最近突然想认真研究下java web常用框架，虽然现在一直在用，但实现的整体流程不是很了解，就在网上搜索资料，尝试自己搭建，以下是自己的搭建及测试过程。

一、准备工作：

　　　　 1/安装并配置java运行环境

　　　　 2/数据库的安装配置（Mysql）

　　　　 3/安装并配置服务器(Tomcat)

　　　　 4/ IntelliJIDEA的安装配置（本人使用的主要软件是IntelliJIDEA）

　　 　　5/ 使用IntelliJIDEA创建一个web app项目

二、下载jar包（也可以用maven）

springMVC及spring需要的jar包spring-core.jar，spring-beans.jar，spring-web.jar，spring-webmvc.jar等

参考：https://www.cnblogs.com/leskang/p/5426829.html

Hibernate4需要的jar包antlr-2.7.7.jar，dom4j-1.6.1.jar，hibernate-core-4.2.21.Final.jar，hibernate-commons-annotations-4.0.2.Final.jar等

参考：https://blog.csdn.net/doodoofish/article/details/43207

三、文件结构

四、配置文件

1.springMVC配置

resources/config/springMVC-servlet.xml

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <!-- 定义controller扫描包 -->
    <context:component-scan base-package="com.qc.mall" >
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>
    <mvc:annotation-driven />

    <!-- 配置视图解析器 -->
    <bean id="viewResolver" 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>
    <!--这里是对静态资源的映射-->
    <mvc:resources mapping="/js/**" location="/WEB-INF/views/js/" />
    <mvc:resources mapping="/css/**" location="/WEB-INF/views/css/" />
    <mvc:resources mapping="/img/**" location="/WEB-INF/views/images/" />

    <mvc:default-servlet-handler/>
</beans>

对应web.xml,包括springMVC的配置，且添加了字符集过滤：

 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!-- spring MVC config start-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 此处指向的的是SpringMVC的配置文件 -->
            <param-value>classpath:config/springMVC-servlet.xml</param-value>
        </init-param>
        <!--配置容器在启动的时候就加载这个servlet并实例化-->
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- spring MVC config end-->
    <!--  字符集过滤  -->
    <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>

    <welcome-file-list>
        <welcome-file>views/test.jsp</welcome-file>
    </welcome-file-list>
</web-app>

然后写个测试方法测试下

在controller层新建一个MainController，内容如下：

package com.qc.mall.controller;

import com.qc.mall.webservice.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class MainController {
    @Autowired
    private TestService testService;

    @RequestMapping(value = "test", method = RequestMethod.GET)
    public String test(){
//        实际返回的是views/test.jsp ,spring-mvc.xml中配置过前后缀
        return "test";
    }
}

test.jsp内容如下：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<center>
    <h2 style="color: #ff261a;">this is my test page!</h2>
</center>
</body>
</html>

启动Tomcat，在浏览器中访问http://mall.jincaidongli.com:8080/test(这里我配置的自己的域名)。

成功！

2.SpringMVC+Spring整合

配置applicationContext.xml 这个Spring的配置文件：

<?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:aop="http://www.springframework.org/schema/aop" xmlns:cache="http://www.springframework.org/schema/cache"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
       xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jms="http://www.springframework.org/schema/jms" xmlns:lang="http://www.springframework.org/schema/lang"
       xmlns:mvc="http://www.springframework.org/schema/mvc"  xmlns:p="http://www.springframework.org/schema/p"
       xmlns:task="http://www.springframework.org/schema/task" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
        http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd
        http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.1.xsd
        http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd"
       default-lazy-init="false">

    <!--********************************************配置Spring***************************************-->
    <!-- 配置自动扫描的包 -->
    <context:component-scan base-package="com.qc.mall">
        <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <context:property-placeholder location="classpath:config/config.properties"/>
    <aop:config proxy-target-class="true"></aop:config>

    <!-- 事物管理器配置  -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <!-- 开启事务注解-->
    <tx:annotation-driven transaction-manager="transactionManager"  />

</beans>

我这里把头文件全部写上了，因为之前因为头文件不全导致，编译一直不成功。

web.xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!--加载Spring的配置文件到上下文中去-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:/config/applicationContext.xml
        </param-value>
    </context-param>

    <!-- spring MVC config start-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 此处指向的的是SpringMVC的配置文件 -->
            <param-value>classpath:config/springMVC-servlet.xml</param-value>
        </init-param>
        <!--配置容器在启动的时候就加载这个servlet并实例化-->
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- spring MVC config end-->

    <!-- Spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--  字符集过滤  -->
    <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>

    <welcome-file-list>
        <welcome-file>views/test.jsp</welcome-file>
    </welcome-file-list>
</web-app>

配置完成，开始测试：

TestService.java

package com.qc.mall.webservice;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class TestService {
    public String test() {
        return "test";
    }
}

MainController控制器代码如下：

package com.qc.mall.controller;

import com.qc.mall.webservice.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class MainController {
    @Autowired
    private TestService testService;

    @RequestMapping(value = "test", method = RequestMethod.GET)
    public String test(){
//        实际返回的是views/test.jsp ,spring-mvc.xml中配置过前后缀
        return "test";
    }

    @RequestMapping(value = "springtest", method = RequestMethod.GET)
    public String springTest(){
        return testService.test();
    }
}

重启Tomcat，在浏览器地址栏输入http://mall.jincaidongli.com:8080/springtest

测试成功！

3.SpringMVC+Spring+Hibernate整合

首先配置下数据库连接及hibernate配置信息文件，config.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/qcshop?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto = update

 接下来配置hibernate，将其配置到applicationapplicationContext.xml文件中：

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

    <tx:annotation-driven transaction-manager="transactionManager"  />

</beans>

配置结束，整体测试。

实体类（Entity）

package com.qc.mall.entity;

import javax.persistence.*;

@Entity
@Table(name = "Person")
public class Person {

    private Long id;
    private Long created = System.currentTimeMillis();
    private String username;
    private String address;
    private String phone;
    private String remark;

    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }

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

    public Long getCreated() {
        return created;
    }

    public void setCreated(Long created) {
        this.created = created;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }
}

数据库访问层（DAO）

package com.qc.mall.dao;


import com.qc.mall.entity.Person;

public interface PersonDao extends BaseDao<Person,Long> { }

dao层实现类

package com.qc.mall.dao.impl;

import com.qc.mall.dao.PersonDao;
import com.qc.mall.entity.Person;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public class PersonDaoImpl implements PersonDao {

    @Autowired
    private SessionFactory sessionFactory;

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

    public Person load(Long id) {
        return (Person)getCurrentSession().load(Person.class,id);
    }

    public Person get(Long id) {
        return (Person)getCurrentSession().get(Person.class,id);
    }

    public List<Person> findAll() {
        return null;
    }

    public void persist(Person entity) {
        getCurrentSession().persist(entity);
    }

    public Long save(Person entity) {
        return (Long)getCurrentSession().save(entity);
    }

    public void saveOrUpdate(Person entity) {
        getCurrentSession().saveOrUpdate(entity);
    }

    public void delete(Long id) {
        Person person = load(id);
        getCurrentSession().delete(person);
    }

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

 业务层（Service）

package com.qc.mall.service;


import com.qc.mall.dao.PersonDao;
import com.qc.mall.entity.Person;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class  PersonService {

    @Autowired
    private PersonDao personDao;

    public Long savePerson() {
        Person person = new Person();
        person.setUsername("sijizhen");
        person.setPhone("1526568652");
        person.setAddress("sijizhen");
        person.setRemark("this is sijizhen");
        return personDao.save(person);
    }
}

控制层（Controller）

package com.qc.mall.controller;

import com.qc.mall.service.PersonService;
import com.qc.mall.webservice.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class MainController {
    @Autowired
    private TestService testService;
    @Autowired
    private PersonService personService;

    @RequestMapping(value = "test", method = RequestMethod.GET)
    public String test(){
//        实际返回的是views/test.jsp ,spring-mvc.xml中配置过前后缀
        return "test";
    }

    @RequestMapping(value = "springTest", method = RequestMethod.GET)
    public String springTest(){
        return testService.test();
    }

    @RequestMapping(value = "savePerson", method = RequestMethod.GET)
    @ResponseBody
    public String savePerson(){
        personService.savePerson();
        return "success!";
