自定义视图

Posted 2020-07-03 seven_hu

package com.seven.views;

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.View;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Date;
import java.util.Map;

/**
 * Created by hu on 2016/4/2.
 */
//必须添加@Component，这样SpringMvc才会感知这个View
@Component
public class HelloView implements View {
    @Override
    public String getContentType() {
        return "text/html";
    }
    @Override
    public void render(Map<String, ?> map, HttpServletRequest httpServletRequest,
                       HttpServletResponse httpServletResponse) throws Exception {
        httpServletResponse.getWriter().print("hello view,time: "+new Date());
    }
}

　　

package com.seven.demos;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by hu on 2016/4/2.
 */
@Controller
@RequestMapping("/SpringMvcTest2")
public class SpringMvcTest2 {

    @RequestMapping("/helloView")
    public String getHelloView(){
        System.out.println("enter");
        return "helloView";
