三步轻松搭建springMVC框架

<!-- springMvc前端控制器 --><servlet><servlet-name>springMvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 指定springMvc核心配置文件位置如果没有指定那么默认就会去"/WEB-INF/+ <servlet-name>标签中内容 + -servlet.xml"中找例如:"/WEB-INF/springMvc-servlet.xml"--><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:SpringMvc.xml</param-value></init-param><load-on-startup>2</load-on-startup></servlet><servlet-mapping><servlet-name>springMvc</servlet-name><url-pattern>*.action</url-pattern></servlet-mapping>
