  • 简化SSH框架的整合

    一、开发环境:

    (1)    OS:Windows 7

    (2)    DB:MySql 5.1.6

    (3)    JDK:1.8.0_17

    (4)    Server:Apache Tomcat 8.0.26

    (5)    IDE:Eclipse

    二、SSH框架版本:

    (1)    Struts2.3.2

    (2)    Spring4.0.2

    (3)    Hibernate5.2.5

    注意:我根据需要并没有导入所有JAR 包;

    三、配置Sturts2框架:

    1.在eclipse新建一个项目news;

    2.导入Sturts2.X的jar包;

     

    3.然后配置在WebContext/WEB-INF/web.xml:

     1   <display-name>news</display-name>
     2   <welcome-file-list>
     3     <welcome-file>default.jsp</welcome-file>
     4   </welcome-file-list>
     5   <filter>
     6     <filter-name>struts2</filter-name>
     7     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
     8   </filter>
     9   <filter-mapping>
    10     <filter-name>struts2</filter-name>
    11     <url-pattern>/*</url-pattern>
    12   </filter-mapping>

    注意:default.jsp代表一个默认首页;

    注意:/*代表过滤所有;

    注意:struts2的入口是一个过滤器,所以可以把struts2当过滤器来配置;

    4.然后配置src/struts.xml

    <!-- 第1步:先定义一个包 -->
        <package name="mypck001" extends="struts-default">
            <!-- myNewsAction用于spring注入 -->
            <action name="NewsAction_*" class="myNewsAction" method="{1}">
                <result name="success">/WEB-INF/jsp/index.jsp</result>
                <result name="deleteOK">/WEB-INF/jsp/ok.jsp</result>
                <result name="deleteFailed">/WEB-INF/jsp/error_delete.jsp</result>
            </action>        
        </package>

    注意:NewsAction_*代表所有以NewsAction_开头的地址;

    注意:{1}代表方法名跟NewsAction_*中*的值一样;

    5.然后创建4个jsp文件:default.jsp、Index.jsp、ok.jsp、error.jsp

    default.jsp文件放在WEBContext目录下,很方便的跳转运行项目;

    
    

    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
      <% response.sendRedirect("myNews2Action_getMyNewsAll.action"); %>
    </body>
    </html>

    其他三个,为了防止用户直接访问JSP页面把它们放在WEB-INF下;

    6.然后再src目录myNews2.action包下创建MyNews2Action.action;

    四、配置spring框架:

    1.添加spring jar包;

    注意:spring框架需要通过struts2-spring-plugin-2.3.30 jar 以struts插件的形式连接struts;

    2.然后配置web.xml

    1   <context-param>
    2     <param-name>contextConfigLocation</param-name>
    3     <param-value>classpath:applicationContext.xml</param-value>
    4   </context-param>
    5   <listener>
    6     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    7   </listener>

    注意:spring以监听器的形式监听所有实例的创建;

    注意:applicationcontext.xml是spring的配置文件,因为它的默认查找路径在WEB—INF/classses下,而我们要把它放到src下就在这配置一下;

    3.然后在src目录下创建jdbc.properties文件,目的是希望防止不该碰applicationContext.xml文件的人碰它;

    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/news
    jdbc.user=root
    jdbc.password=123456

    4.然后配置applicationContext.xml:

    <context:component-scan base-package="myNews2" />

    注意:它是spring注解解析器,用注解可以各种<Bean>的创建;

        <context:property-placeholder location="classpath:jdbc.properties" />

    !引入jdbc.properties;

    5.然后对各个类进行IOC的注入:

    1 @Repository
    2 @Scope("prototype")
    3 public class MyNewsDaoImpl implements MyNewsDao {
    4 
    5     @Resource
    6     private SessionFactory sf;

    注意:@Repository代表这个类的实例交给spring来管理;

    @Controller
    @Scope("prototype")
    public class MyNews2Action extends ActionSupport{
        
        @Resource
        private MyNewsService ms;

    注意:@Scope("prototype")代表这个类的作用范围;

    @Service
    @Scope("prototype")
    public class MyNews2ServiceImpl implements MyNewsService {
        
        @Resource
        private MyNewsDao mn;

    注意:模型层用@Service,控制层用@Controller,数据层用@Repository;

    注意:@Resource是JDK 解析器;spring的是@Autowired和Qualifier;

    五、配置Hibernate框架:

    1.添加Hibernate jar包;

    2.配置applicationContext.xml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:p="http://www.springframework.org/schema/p"
        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
        xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
        xsi:schemaLocation="    
                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd  
                http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd  
                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
                http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.2.xsd  
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">
        
        <context:component-scan base-package="myNews2" />
    
        <context:property-placeholder location="classpath:jdbc.properties" />
    
        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"
            scope="prototype">
            <property name="dataSource" ref="dataSource"></property>
    
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                    <prop key="hibernate.show_sql">true</prop>
                    <prop key="hibernate.format_sql">true</prop>
                    <!-- 禁用自动提交,保护事务的完整性 -->
                    <prop key="hibernate.connection.autocommit">false</prop>
                    <!-- 开机自动生成表 -->
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                </props>
            </property>
            <property name="mappingResources">
                    <list>
                        <value>News.hbm.xml</value>
                    </list>
            </property>
        </bean>
        
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
                <property name="driverClass" value="${jdbc.driver}" />
                <property name="jdbcUrl" value="${jdbc.url}" />
                <property name="user" value="${jdbc.user}" />
                <property name="password" value="${jdbc.password}" />
                <!-- 每300秒检查所有连接池中的空闲连接 -->
                <property name="idleConnectionTestPeriod" value="300"></property>
                <!-- 最大空闲时间,900秒内未使用则连接被丢弃。若为0则永不丢弃 -->
                <property name="maxIdleTime" value="900"></property>
                <!-- 最大连接数 -->
                <property name="maxPoolSize" value="2"></property>
        </bean>
    
    </beans>

    3.配置News.hbm.xml文件:

    <?xml version="1.0" encoding="UTF-8"?>
    <hibernate-mapping xmlns="http://www.hibernate.org/xsd/hibernate-mapping">
         <class name="myNews2.entity.News" table="news">
             <id name="id" column="id">
                <generator class="native"/>         
             </id>
             <!-- 属性对应字段  -->
            <property name="title" type="string" length="50" column="title" not-null="true"></property>
             <property name="content" type="text" length="50000" column="content" not-null="true"></property>
            <property name="begintime" type="date" column="begintime" not-null="true"></property>
            <property name="username" type="string" length="20" column="username" not-null="true"></property>
        </class>
    </hibernate-mapping>

     测试MyNews2Action.action

     启动Tomcat

    测试URL:http://localhost:8080/myNews2/MyNews2Action.action
