SpringBoot复习：（28）【前后端不分离】自定义View

一、自定义View

package cn.edu.tju.view;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.ViewResolver;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Map;@Component
public class MyView implements View {@Overridepublic String getContentType() {return "text/html";}@Overridepublic void render(Map<String, ?> model, HttpServletRequest request, HttpServletResponse response) throws Exception {response.getWriter().write("hello, world.this is my view");}
}

二、控制器返回视图名称指向上述View

package cn.edu.tju.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
public class ViewController {@RequestMapping("/view")public String getView(){return "myView";}
}

BeanNameViewResolver就会把我自定义的myView这个视图解析到MyVIew这个view类。
