/**

* Spring 自定义视图

* 1、需要配置bean org.springframework.web.servlet.view.BeanNameViewResolver

* 2、自定义类中继承view或者起子类view例如AbstractExcelView

* @return

测试类：

package com.spring.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.spring.view.TestView;@Controllerpublic class TestController {/** * Spring 自定义视图 * 1、需要配置bean org.springframework.web.servlet.view.BeanNameViewResolver *  * 2、自定义类中继承view或者起子类view例如AbstractExcelView *  * @return */@RequestMapping("testTestView")public TestView testTestView(){TestView tv = new TestView();return tv;}//@RequestMapping("testTestView2")//public String testTestView2(){////return "TestView";//}}

TestView:

package com.spring.view;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Component;import org.springframework.web.servlet.View;@Componentpublic class TestView implements View{@Overridepublic String getContentType() {// TODO Auto-generated method stubreturn "text/html";}@Overridepublic void render(Map<String, ?> map, HttpServletRequest request, HttpServletResponse response) throws Exception {// TODO Auto-generated method stubrequest.getRequestDispatcher("WEB-INF/views/index.jsp").forward(request, response);//response.sendRedirect("http://www.baidu.com");}}
