(转载)Struts Spring Hibernate (SSH) 整合实例

首选创建web.xml 主要是配置Struts的ActionServlet和Spring的字符过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee  http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  
<filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
  
<servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts/struts.xml</param-value>
    </init-param>
    <init-param>

      <param-value>3</param-value>
    </init-param>

      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>
  
<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>
  
<!-- session超时定义,单位为分钟 -->
<session-config>
    <session-timeout>10</session-timeout>
</session-config>
  
<!-- 默认首页定义 -->
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>
  
</web-app>

然后创建struts.xml(String配置文件) 要注意这里集成了Spring插件,把全部Spring配置文件注入到ContextLoaderPlugIn中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>

<form-beans>
<form-bean name="loginVO" type="com.vo.LoginVO" />
</form-beans>

<global-forwards>
<forward name="error" path="/error.jsp"/>
</global-forwards>

<action-mappings>
<action path="/login"
    name="loginVO"
       type="org.springframework.web.struts.DelegatingActionProxy"
       parameter="action"
       scope="request">
       <forward name="login" path="/login.jsp"/>
       <forward name="index" path="/index.jsp"/>
   </action>
</action-mappings>

<!-- 集成Spring插件 -->
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="contextConfigLocation" value="/WEB-INF/spring/*.xml" />
</plug-in>

</struts-config>


配置Spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 读入属性文件 -->
<bean id="propertyConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="locations">
    <list>
     <value>classpath:hibernate.properties</value>
    </list>
   </property>
</bean>

<!-- 配置数据源，可以其他方式 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
     <property name="driverClassName" value="${hibernate.driverClassName}" />
   <property name="url" value="${hibernate.url}" />
   <property name="username" value="${hibernate.username}" />
   <property name="password" value="${hibernate.password}" />
     <property name="maxActive" value="${hibernate.maxActive}" />
   <property name="maxIdle" value="${hibernate.maxIdle}" />
   <property name="maxWait" value="${hibernate.maxWait}" />
    </bean>

<!-- 配置Hibernate的Session工厂，注入数据源、映射文件 -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource">
         <ref local="dataSource"/>
    </property>
        <property name="mappingResources">
            <list>
                <value>com/po/login.hbm.xml</value>
            </list>
        </property>
        <property name="hibernateProperties">
       <props>
         <prop key="hibernate.dialect">${hibernate.dialect}</prop>
         <prop key="hibernate.show_sql">${hibernate.showSQL}</prop>
       </props>
    </property>
    </bean>

<!-- 声明Hibernate事务管理，注入Session工厂 -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
     <property name="sessionFactory">
       <ref local="sessionFactory"/>
     </property>
</bean>

<!-- 配置事务代理，注入事务管理transactionManager，由Spring来代理事务，设置事务属性 -->
    <bean id="transactionProxy" abstract="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
     <property name="transactionManager">
       <ref bean="transactionManager"/>
     </property>
     <property name="transactionAttributes">
       <props>
           <prop key="save*">PROPAGATION_REQUIRED,-Exception</prop>
               <prop key="add*">PROPAGATION_REQUIRED,-Exception</prop>

               <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
               <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
               <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
               <prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
               <prop key="*">PROPAGATION_REQUIRED</prop>
       </props>
     </property>
    </bean>
</beans>


配置Action将Service注入到Action

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 配置Action，singleton属性设置为false表示不使用单例，每次都重新创建实例，避免并发问题，注入事务管理的Service -->
   <bean name="/login" class="com.action.LoginAction" singleton="false">
    <property name="loginService">
        <ref bean="loginService"/>
        </property>
   </bean>
</beans>

配置Service将Dao注入到Service

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 配置事务代理Service，先将Dao注入到Service，再将Service注入给事务代理 -->
    <bean id="loginService" parent="transactionProxy">
     <property name="target">
     <ref bean="loginTempService"/>
     </property>
</bean>
<bean id="loginTempService" class="com.service.LoginService">
        <property name="loginDao">
        <ref bean="loginDao"/>
        </property>
    </bean>
</beans>

配置Dao 注入Session工厂

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 配置Dao，注入Session工厂 -->
    <bean id="loginDao" class="com.dao.LoginDao">
        <property name="sessionFactory">
        <ref bean="sessionFactory"/>
        </property>
    </bean>
</beans>

数据源属性文件(注意不是Hibernate的配置文件,是为了让Spring读入的)

hibernate.dialect=org.hibernate.dialect.SQLServerDialect
hibernate.driverClassName=com.mysql.jdbc.Driver
hibernate.url=jdbc:mysql://127.0.0.1:3306/ssh
hibernate.username=root
hibernate.password=5719
hibernate.showSQL=true
hibernate.maxActive=50
hibernate.maxIdle=30
hibernate.maxWait=1000

log4j配置文件(简单)

log4j.rootLogger=ERROR,console,file

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-5p %d [%F,%L] - %m%n

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=F:\\SSH.log
#log4j.appender.file.MaxFileSize=100000KB
#log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-5p %d [%F,%L] - %m%n
