视图解析器------默认就有配置,但是默认的在实际使用过程中有很多不方便的地方,所以我们配置一道视图解析器

在自己的配置文件xml中,配一个bean节点

    <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--前-->
<property name="prefix" value="/"></property>
<!--后-->
<property name="suffix" value=".jsp"></property>
</bean>

在自定义的处理器中就可以省略/和.jsp的写法

package cn.dawn.day02viewResolver;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; /**
* Created by Dawn on 2018/3/19.
*/
//处理器
public class FirstController implements Controller {
/**
* handleRequest 处理请求
* @param httpServletRequest
* @param httpServletResponse
* @return
* @throws Exception
*/
public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
ModelAndView me=new ModelAndView();
//因为视图解析器已经把前后所要写的/和.jsp写了,此处的index就代表/index.jsp
me.setViewName("index");
return me;
}
}
