SSM框架中常用的配置文件
学习框架，刚开始的时候最烦的就是一些配置文件，有很多需要配置的东西，今天把这些配置文件信息稍微整理一下，以后说不定会用的到。
web.xml文件
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!-- 配置加载Spring文件的监听器--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 编码过滤器 --> <filter> <filter-name>encoding</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>encoding</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <!-- 配置Spring MVC前端核心控制器 --> <servlet> <servlet-name>crm</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc-config.xml</param-value> </init-param> <!-- 配置服务器启动后立即加载Spring MVC配置文件 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>crm</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
springmvc的配置文件 springmvc-config.xml
