三大框架SSH(struts2+spring+hibernate)整合时相关配置文件的模板

        最近在学SSH三大框架的整合，在此对他们整合时相关配置文件做一简单的模板总结，方便以后复用！

        首先是web.xml配置文件，这里面就配置一些简单的监听器、过滤器，包括spring核心配置文件applicationContext.xml的路径：

web.xml

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
</web-app>

       接着就是spring的配置文件：applicationContext.xml，可能很多人更习惯命名为beans.xml，由于习惯使用注解方式开发，所以这个是基于annotation的配置，相对xml比较简单！由于这里面已经完成了hibernate配置文件的功能，比如配置数据库等等，所以hibernate.cfg.xml就没必要“苟活”了。

applicationContext.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:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/tx 
           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

	<context:annotation-config />
	<context:component-scan base-package="com.zzw" />

	<context:property-placeholder location="classpath:jdbc.properties" />
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="${jdbc.driverClassName}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<!-- 指定连接数据库连接池的初始化连接数 -->
		<property name="initialPoolSize" value="1" />
		<!-- 指定连接数据库连接池的最大连接数 -->
		<property name="maxPoolSize" value="40" />
		<!-- 指定连接数据库连接池的最小连接数 -->
		<property name="minPoolSize" value="1" />
		<!-- 指定连接数据库连接池的连接的最大空闲时间 -->
		<property name="maxIdleTime" value="20" />
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="packagesToScan">
			<list>
				<value>com.zzw.entity</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="javax.persistence.validation.mode">none</prop>
				<prop key="hibernate.format_sql">true</prop>
			</props>
		</property>
	</bean>

	<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>

	<bean id="txManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

	<aop:config>
		<aop:pointcut id="service"
			expression="execution(public * com.zzw.service..*.*(..))" />
		<aop:advisor pointcut-ref="service" advice-ref="txAdvice" />
	</aop:config>

	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="get*" read-only="true" />
			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="add*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
		</tx:attributes>
	</tx:advice>
</beans>

 

        由于上面的配置文件涉及到运用DataSource得起数据库的连接，关系到jdbc.properties文件，所以在此举一个mysql的简单示例：

jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssh
jdbc.username=root
jdbc.password=root

 

       关于log4j的日志记录，没什么可说的，根据需要配置，简单示例如下：

log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file hibernate.log ###
#log4j.appender.file=org.apache.log4j.FileAppender
#log4j.appender.file.File=hibernate.log
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=warn, stdout

#log4j.logger.org.hibernate=info
#log4j.logger.org.hibernate=debug

### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug

### log just the SQL
#log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ###
#log4j.logger.org.hibernate.type=info
#log4j.logger.org.hibernate.type=debug

### log schema export/update ###
log4j.logger.org.hibernate.tool.hbm2ddl=debug

### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug

### log cache activity ###
#log4j.logger.org.hibernate.cache=debug

### log transaction activity
#log4j.logger.org.hibernate.transaction=debug

### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug

### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace

 

        至于struts.xml文件的配置就根据具体action的要求来了，比如我这次的雇员管理系统里面的简单配置如下：

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<constant name="struts.devMode" value="true" />

	<package name="default" namespace="/" extends="struts-default">
		<action name="employee" class="com.zzw.action.EmployeeAction">
			<result name="loginSuccess">/showAllEmployee.jsp</result>
			<result name="loginFail">/loginFail.jsp</result>
			<result name="showAll">/showAllEmployee.jsp</result>
			<result name="addSuccess">/add_success.jsp</result>
			<result name="deleteSuccess">/delete_success.jsp</result>
			<result name="goUpdatePage">/updateEmployee.jsp</result>
			<result name="updateSuccess">/updateSuccess.jsp</result>
			
		</action>
	</package>
</struts>

       以上基本都是这次雇员管理系统的相关配置实例，很多地方简单化，实际上还可优化，所以仅作为参考，具体根据项目需要进行修改！
