SSM三大框架组合

1.1导包

1.2配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>ssm_spring_mvc</display-name>
  
  <!-- 配置springmvc前端控制器和读取配置文件 -->
  <servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<!-- 读取配置文件 -->
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:applicationContext.xml</param-value>
  	</init-param>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>springmvc</servlet-name>
  	<!-- 拦截规则
  		1 *.html *.do *action 以扩展名方式进行拦截，不拦截静态资源 .jpg .css .js .png什么情况下都可以使用
  		2 / 不拦截jsp，拦截静态资源 .jpg .css .js .png          RESTful风格 静态资源放行 
  		/* 全部拦截 包括jsp和所有静态资源 不推荐使用
  	 -->
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

1.3配置applicationContext.xml
配置表头：选中applicationContext.xml文件，右键→Open With→Other→Spring Config Editor→选中aop、beans、context、mvc、tx。
