Spring+Struts2+Hibernate 整合笔记

1.导包

Hibernate导包

    hibernate/lib/required/*目录下的全部的jar包

    hibernate/lib/jpa | java persist api java的持久化规范(接口)

  

    数据库驱动(MySQL)

    

Struts2 导包

    struts-blank.war/WEB-INF/lib/*目录下的全部的jar包

    注意:javassist-3.18.1-GA.jar包与hibernate中的重复,留下高版本

    String 整合的插件包

    

Spring 导包

    4个基本包+2个日志包

      core|beans|context|expression|logging|log4j

    web整合包:

      spring-Web

    整合aop 4 个:

      spring-aop|spring-aspect|aop联盟|aopweaving

    整合Hibernate和事务4个

      spring-jdbc|spring-tx|c3p0|spring-orm

    整合Junit4测试

      spring-test

    在eclipse下还需导入标签包

        standard.jar

        jstl-1.2.jar

共计41个包

 2.单独配置spring容器

     

    web.xml配置(使Spring随web启动而启动) 

1   <!-- 配置Spring的监听器 -->
2   <listener>
3       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
4   </listener>
5   <!-- 为Spring容器创建传递参数 -->
6   <context-param>
7       <param-name>contextConfigLocation</param-name>
8       <param-value>classpath:applicationContext.xml</param-value>
9   </context-param>
Spring XML配置

单独配置struts2

1.配置Struts2核心过滤器web.xml

1  <!-- struts2核心过滤器 -->
2   <filter>
3       <filter-name>struts2</filter-name>
4       <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
5   </filter>
6   <filter-mapping>
7       <filter-name>struts2</filter-name>
8       <url-pattern>/*</url-pattern>
9   </filter-mapping>
Struts2 核心过滤器

Spring整合Struts2配置

  配置常量

<constant name="struts.objectFactory" value="spring"></constant>

  Spring负责创建Action负责创建

1 <package name="strutsTest" namespace="/" extends="struts-default">
2         <!-- Class属性上填写Spring中Action对象的BeanName,由Spring来控制action的生命周期,
3             注意:需要手动处理依赖属性-->
4         <action name="strutsTest" class="cn.test.demo.StrutsTest" method="Test">
5             <result name="success">/success.jsp</result>
6         </action>
7     </package>
Struts 配置
1 <!-- action 对象作用范围一定是多例的prototype -->
2     <bean name="strutsTest" class="cn.test.demo.StrutsTest" scope="prototype">
3         <property name="springTest" ref="springTest"></property>
4     </bean>
Spring中配置

 Spring 整合Hibernate配置

  将sessionFactory交给Spring管理

 1 <!-- 配置Hibernate基本信息 -->
 2     <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
 3         <property name="dataSource" ref="dataSource"></property>
 4         <property name="hibernateProperties">
 5             <props>
 6                 <!-- 必要配置 -->
 7                 <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
 8                 <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
 9                 <prop key="hibernate.connection.url">jdbc:mysql:///crm?useSSL=true</prop>
10                 <prop key="hibernate.connection.username">root</prop>
11                 <prop key="hibernate.connection.password">root</prop>
12                 <!-- 可选配置 -->
13                 <prop key="hibernate.show_sql">true</prop>
14                 <prop key="hibernate.format_sql">true</prop>
15                 <prop key="hibernate.hbm2ddl.auto">update</prop>
16             </props>
17         </property>
18         <property name="mappingDirectoryLocations" value="classpath:cn/test/domain"></property>
19     </bean>
Spring - Hibernate 基本配置
1 <!-- 配置核心管理器 -->
2     <bean name="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
3         <property name="sessionFactory" ref="sessionFactory"></property>
4     </bean>
Hibernate 核心管理器
 1     <!-- 配置事务策略 -->
 2     <tx:advice id="txadvice" transaction-manager="transactionManager">
 3         <tx:attributes>
 4             <tx:method name="save*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
 5             <tx:method name="persist*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
 6             <tx:method name="update*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>

 8             <tx:method name="delete*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
 9             <tx:method name="get*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true"/>
10             <tx:method name="find*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true"/>
11         </tx:attributes>
12     </tx:advice>
13     <!-- 配置将通知织入目标 -->
14     <aop:config>
15         <!-- 配置切点 -->
16         <!-- 配置作用那个包下那个类下的的那个方法 -->
17         <aop:pointcut expression="execution(* cn.test.demo.HibernateDemo.*(..))" id="txPc"/>
18         <!-- 配置切面 -->
19         <aop:advisor advice-ref="txadvice" pointcut-ref="txPc"/>
20     </aop:config>
配置事务策略

Spring整合C3P0连接池

1 <!-- 读取c3p0配置文件 -->
2     <context:property-placeholder location="classpath:db.properties"/>
3     <!-- c3p0的配置 -->
4     <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
5         <property name="jdbcUrl" value="${jdbc.jdbcUrl}"/>
6         <property name="driverClass" value="${jdbc.driverClass}"></property>
7         <property name="user" value="${jdbc.user}"></property>
