Springmvc快速入门（XML版本）简单配置

步一：创建springmvc-day01这么一个web应用

步二：导入springioc，springweb , springmvc相关的jar包



步三：在/WEB-INF/下创建web.xml文件

<!-- 注册springmvc框架核心控制器 -->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>  <!-- 此处可以自己起名字，要保证一致 -->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>

步四：创建HelloAction.java控制器类

public class HelloAction implements Controller {

@Override
public ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) throws Exception {

ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("msg", "hello world");
modelAndView.setViewName("/success.jsp");
return modelAndView;
}

}

步五：在/WebRoot/下创建jsp/success.jsp

步六：在/WEB-INF/创建DispatcherServlet-servlet.xml配置文件，xml头部信息与 spring.xml相同

注意：该配置文件的命名规则：web.xml文件中配置的的值- servlet.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"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="

 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd

">

<!-- 控制器(程序员) -->
<bean name="/hello.action" class="com.smvc.action.HelloAction"></bean>
</beans>

到此可以发布运行啦！！！！
