FirstController 类
public class FirstController implements Controller {
public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
ModelAndView mv=new ModelAndView();
mv.addObject("uname","小仙女");
mv.setViewName("/index");
return mv;
}
}

<body>

在换另一个配置时，在web.xml中更改
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springMVC02hander.xml</param-value>
</init-param>
在类中更改：
public class SecondController extends AbstractController{
protected ModelAndView handleRequestInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
ModelAndView mv=new ModelAndView();
mv.addObject("uname","你是不是傻");
mv.setViewName("/index");
return mv;
}
}
