struts2.3.14+spring3.1.1+hibernate4.1.0框架搭建新版SSH(中)

wangchao 2013-05-23

在上一篇文章中主要说了一下需要导入的jar包,此篇文章来讲解具体的配置。

三、具体的配置文件的配置

1、首先配置一下web.xml。应该是个很主要的方面

a、欢迎界面的配置

<!-- 配置默认欢迎界面 -->
 <welcome-file-list>
  <welcome-file>index.html</welcome-file>
 </welcome-file-list>

b、log4j文件位置的配置,以前可能都没配置过这个东西,因为默认情况下log4j.properties文件需要放在src目录下,即所谓的classpath:目录。下面还有个配置具体的意思不是很懂,一下配置一下就行了。还有个spring对log4j的支持。具体的配置如下所示

<context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>classpath:/edu/qdlms/logic/resources/log4j.properties</param-value>
 </context-param>
  
 <context-param>
  <param-name>log4jRefreshInterval</param-name>
  <param-value>60000</param-value>
 </context-param>
 
 <!-- 为了防止出现log4j异常 -->
 <listener> 
 <listener-class> 
 org.springframework.web.util.Log4jConfigListener 
 </listener-class> 
 </listener>>

c、spring的配置,spring默认的文件路径是src目录下,看着有点不舒服,所以也把他放到resources包中。下面的listener必须配

<!-- 配置spring的路径 -->
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:/edu/qdlms/logic/resources/applicationContext-common.xml</param-value>
 </context-param>
 
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

d、struts的配置

<!-- struts 的配置 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

		<init-param>
			<param-name>config</param-name>
			<param-value>struts-default.xml,struts-plugin.xml,classpath:/edu/qdlms/logic/resources/struts.xml</param-value>
		</init-param>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>


e、其它错误文件的配置

<error-page>  
        <error-code>404</error-code>  
        <location>/page/exception/404.jsp</location>  
    </error-page>  
    <error-page>  
        <error-code>500</error-code>  
        <location>/page/exception/500.jsp</location>  
    </error-page>


f、这里配置的比较少,下面把整个web.xml文件贴出来

<?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_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<display-name>QDLMS</display-name>

	<!-- 配置默认欢迎界面 -->
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
	</welcome-file-list>

	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>classpath:/edu/qdlms/logic/resources/log4j.properties</param-value>
	</context-param>
		
	<context-param>
		<param-name>log4jRefreshInterval</param-name>
		<param-value>60000</param-value>
	</context-param>
	
	<!-- 为了防止出现log4j异常 -->
	<listener>  
        <listener-class>  
            org.springframework.web.util.Log4jConfigListener  
        </listener-class>  
    </listener> 

	<!-- 配置spring的路径 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:/edu/qdlms/logic/resources/applicationContext-common.xml</param-value>
	</context-param>
	
	<listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

	<!-- struts 的配置 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

		<init-param>
			<param-name>config</param-name>
			<param-value>struts-default.xml,struts-plugin.xml,classpath:/edu/qdlms/logic/resources/struts.xml</param-value>
		</init-param>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<error-page>  
        <error-code>404</error-code>  
        <location>/page/exception/404.jsp</location>  
    </error-page>  
    <error-page>  
        <error-code>500</error-code>  
        <location>/page/exception/500.jsp</location>  
    </error-page> 
</web-app>


2、log4j.properties文件的配置,下面直接贴出代码,具体不懂得参考百度或者谷歌吧。

### 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:%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


3、jdbc.properties文件的配置

a、hibernate的配置

#Hibernate
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.cache.provider_class=net.sf.ehcache.hibernate.EhCacheProvider
hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext


b、数据库连接池(c3p0)的配置

#JDBC
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/qdlmsl
jdbc.username=root
jdbc.password=admin
#C3P0
#Hibernate4 C3P0
jdbc.miniPoolSize = 1
jdbc.maxPoolSize = 20
jdbc.initialPoolSize = 1
jdbc.maxIdleTime = 25000
jdbc.acquireIncrement = 1

jdbc.acquireRetryAttempts = 30
jdbc.acquireRetryDelay = 1000
jdbc.testConnectionOnCheckin = true
jdbc.automaticTestTable = c3p0TestTable
jdbc.idleConnectionTestPeriod = 18000
jdbc.checkoutTimeout=3000


c、整个jdbc.properties文件就不贴出来了

3、struts.xml文件就不用配置了,这里是用的时struts的零配置。所以大家就不用那么麻烦的去配置struts的配置文件了。其中我也在官方下载了一个原版的struts.xml的文件,这里没进行配置。struts的零配置并不是说一点都不需要配置,还有一点配置如下所示(全部注释掉了,回头如果有用到的地方,大家可以百度一下)

<?xml version="1.0" encoding="UTF-8" ?>

    <constant name="struts.convention.package.locators" value="action"/> -->
    
</struts>


4、 下面最重要的配置就是下面applicationContext-common.xml的配置了,一不小心就会出很多的问题

a、添加注解的支持,还有配置所需要扫描的文件包

<!-- post-processors for all standard config annotations -->
	<context:annotation-config />

	<!-- Scans within the base package of the application for @Components to 
		configure as beans -->
	<context:component-scan base-package="edu.qdlms.logic.*" />

b、jdbc.properties文件位置的配置

<!--  jdbc.properties文件位置的配置 -->	
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations"
			value="classpath:/edu/qdlms/logic/resources/jdbc.properties" />
	</bean>

c、c3p0连接池配置

<!-- c3p0连接池配置 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="${jdbc.driverClass}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="minPoolSize" value="${jdbc.miniPoolSize}" />
		<property name="maxPoolSize" value="${jdbc.maxPoolSize}" />
		<property name="initialPoolSize" value="${jdbc.initialPoolSize}" />
		<property name="maxIdleTime" value="${jdbc.maxIdleTime}" />
		<property name="acquireIncrement" value="${jdbc.acquireIncrement}" />

		<property name="acquireRetryAttempts" value="${jdbc.acquireRetryAttempts}" />
		<property name="acquireRetryDelay" value="${jdbc.acquireRetryDelay}" />
		<property name="testConnectionOnCheckin" value="${jdbc.testConnectionOnCheckin}" />
		<property name="automaticTestTable" value="${jdbc.automaticTestTable}" />
		<property name="idleConnectionTestPeriod" value="${jdbc.idleConnectionTestPeriod}" />
		<property name="checkoutTimeout" value="${jdbc.checkoutTimeout}" />
	</bean>

d、配置SessionFactory

<!-- 配置SessionFactory,据说这个packagesToScan不能扫描子包 -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="packagesToScan">
			<list>
				<value>edu.qdlms.logic.model</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.current_session_context_class">${hibernate.current_session_context_class}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
				<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
				<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
			</props>
		</property>
	</bean>

e、transactionManager的配置

<!-- transactionManager -->
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory">
			<ref local="sessionFactory" />
		</property>
	</bean>

	<!--采用注解来管理Bean -->
	<tx:annotation-driven transaction-manager="transactionManager" />


	<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="create*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="merge*" propagation="REQUIRED" />
            <tx:method name="del*" propagation="REQUIRED" />
            <tx:method name="remove*" propagation="REQUIRED" />
            <tx:method name="put*" propagation="REQUIRED" />
            <tx:method name="use*" propagation="REQUIRED"/>
            <!--hibernate4必须配置为开启事务 否则 getCurrentSession()获取不到-->
            <tx:method name="get*" propagation="REQUIRED" read-only="true" />
            <tx:method name="count*" propagation="REQUIRED" read-only="true" />
            <tx:method name="find*" propagation="REQUIRED" read-only="true" />
            <tx:method name="list*" propagation="REQUIRED" read-only="true" />
            <tx:method name="*" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <aop:config expose-proxy="true">
        <!-- 只对业务逻辑层实施事务 -->
        <aop:pointcut id="txPointcut" expression="execution(* edu.qdlms.logic..service..*.*(..))" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    </aop:config>

f、最后把整个applicationContext-common.xml的代码贴出来
