1.配置3个xml文件
web.xml
web.xml主要配置：ContextLoaderListener和DispatcherServer，代码如下：
<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" 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_3_0.xsd"> <!-- 配置web.xml，使其具有springmvc特性，主要配置两处，一个是ContextLoaderListener，一个是DispatcherServlet --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--防止发生java.beans.Introspector内存泄露,应将它配置在ContextLoaderListener的前面 详细描述见http://blog.csdn.net/jadyer/article/details/11991457 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 配置ContextLoaderListener表示，该工程要以spring的方式启动。启动时会默认在/WEB-INF目录下查找applicationContext.xml作为spring容器的配置文件，该文件里可以初始化一些bean --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- spring mvc 配置 --> <!-- 配置DispatcherServlet表示，该工程将采用springmvc的方式。启动时也会默认在/WEB-INF目录下查找XXX-servlet.xml作为配置文件， XXX就是DispatcherServlet的名字，该文件中将配置两项重要的mvc特性：HandlerMapping,负责为DispatcherServlet这个前端控制器的请求查找Controller； ViewResolver,负责为DispatcherServlet查找ModelAndView的视图解析器。 此处使用指定的配置文件spring-mvc.xml --> <servlet> <servlet-name>Dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--<param-value>/WEB-INF/classes/spring-mvc-servlet.xml</param-value>--> <param-value>classpath*:/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Dispatcher</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <filter> <filter-name>SpringOpenSessionInViewFilter</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> <init-param> <param-name>sessionFactoryBeanName</param-name> <param-value>sessionFactory</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringOpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 字符集过滤器 --> <filter> <filter-name>encodingFilter</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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载Log4j的配置****begin --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 加载Log4j的配置****end --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>applicationContext.xml
配置ContextLoaderListener表示，该工程要以spring的方式启动。启动时会默认在/WEB-INF目录下查找 applicationContext.xml作为spring容器的配置文件，这里可以初始化一些bean，如DataSource等。代码如下：
