springMVC+Hibernate 使用配置

本文描述下 sypro 项目中使用 springMVC+Hibernate配置，初学SpringMVC做下简单整理解。

1.web项目首先我们要使用 web.xml文件将 spring配置引入进来

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<description>springMvc+hibernate4+easyui</description>
	
	<display-name>sypro2.02</display-name>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-ehcache.xml,classpath:spring-apacheFtpServer.xml</param-value>
	</context-param>
	
	<filter>
		<filter-name>openSessionInViewFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>singleSession</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	
	
	<filter>
		<description>字符集过滤器</description>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<description>字符集编码</description>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	
	<filter-mapping>
		<filter-name>openSessionInViewFilter</filter-name>
		<url-pattern>*.do</url-pattern>
	</filter-mapping>
	
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<listener>
		<description>spring监听器</description>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<listener>
		<description>apache ftp server监听器</description>
		<listener-class>sy.util.ApacheFtpServerListener</listener-class>
	</listener>
	
	<listener>
		<description>Introspector缓存清除监听器</description>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>
	
	<servlet>
		<description>spring mvc servlet</description>
		<servlet-name>springMvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<description>spring mvc 配置文件</description>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>springMvc</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	
	
	<session-config>
		<session-timeout>3</session-timeout>
	</session-config>
	
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>init.jsp</welcome-file>
	</welcome-file-list>
	
	<error-page>
		<error-code>404</error-code>
		<location>/error/404.jsp</location>
	</error-page>
	
	<error-page>
		<error-code>500</error-code>
		<location>/error/500.jsp</location>
	</error-page>
	
	<distributable />
	
</web-app>

部署applicationContext的xml文件，如果在web.xml中不写任何参数配置信息，默认的路径是”/WEB-INF/applicationContext.xml，在WEB-INF目录下创建的xml文件的名称必须是applicationContext.xml。如果是要自定义文件名可以在web.xml里加入contextConfigLocation如下，在<param-value> </param-value>里指定相应的xml文件名，如果有多个xml文件，可以写在一起并一“,”号分隔

<display-name>sypro2.02</display-name>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-ehcache.xml,classpath:spring-apacheFtpServer.xml</param-value>
	</context-param>
	
	<filter>
		<filter-name>openSessionInViewFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>singleSession</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>

加载contextConfigLocation则交给监听来实现

<listener>
		<description>spring监听器</description>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

然后配置springMVC处理请求映射

<servlet>
		<description>spring mvc servlet</description>
		<servlet-name>springMvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<description>spring mvc 配置文件</description>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>springMvc</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

2.applicationContext.xml 文件常用配置，在该项目中使用的自定义写法 将 applicationContext.xml 重命名为： spring-mvc.xml ,注意如果不使用自定义写法applicationContext.xml则存放在 /WEB-INF/applicationContext.xml目录且不可重命名

applicationContext.xml （spring-mvc.xml） 常用配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	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/mvc
		http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

	<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
	<context:component-scan base-package="sy.controller" />

	<!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=UTF-8</value>
			</list>
		</property>
	</bean>

	<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
			</list>
		</property>
	</bean>

	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver"
		p:prefix="/" p:suffix=".jsp" />

	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="defaultEncoding">
			<value>UTF-8</value>
		</property>
		<property name="maxUploadSize">
			<value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 -->
		</property>
		<property name="maxInMemorySize">
			<value>4096</value>
		</property>
	</bean>

	<!-- 拦截器 -->
	<mvc:interceptors>
		<mvc:interceptor>
			<mvc:mapping path="/**" />
			<bean class="sy.interceptors.EncodingInterceptor" />
		</mvc:interceptor>
		<mvc:interceptor>
			<mvc:mapping path="/**" />
			<bean class="sy.interceptors.AuthInterceptor" />
		</mvc:interceptor>
	</mvc:interceptors>

</beans>

spring-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"
	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
">

	<!-- 引入属性文件 -->
	<context:property-placeholder location="classpath:config.properties" />

	<!-- 自动扫描dao和service包(自动注入) -->
	<context:component-scan base-package="sy.dao,sy.service" />

</beans>

<!-- 引入属性文件 -->
	<context:property-placeholder location="classpath:config.properties" />

项目配置映入属性文件在配置hibenrate数据库配置提供了便利
如下 spring-hibernate.xml 配置

<?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: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/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
">

	<!-- JNDI方式配置数据源 -->
	<!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 
		<property name="jndiName" value="${jndiName}"></property> </bean> -->

	<!-- dbcp数据源 -->
	<bean name="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${driverClassName}"></property>
		<property name="url" value="${url}"></property>
		<property name="username" value="${username}"></property>

		</property>

		<!-- 注解方式配置 -->
		<!-- <property name="packagesToScan"> <list> <value>sy.hbm</value> </list> 
			</property> -->

		<!-- hbm方式配置 -->
		<property name="mappingDirectoryLocations">
			<list>
				<value>classpath:sy/hbm</value>
			</list>
		</property>
	</bean>

	<!-- 配置事务 -->
	<bean name="transactionManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<tx:annotation-driven transaction-manager="transactionManager" />

</beans>

spring缓存配置

<!-- 开启spring缓存 -->
	<cache:annotation-driven cache-manager="cacheManager" />
	<bean id="cacheManagerFactory"
		class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
		p:configLocation="classpath:ehcache.xml" p:shared="false" />
	<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"
		p:cacheManager-ref="cacheManagerFactory" />
