ViewResolver -Springboot中的视图解析器

项目结构如下（Idea）

 

 

代码

package com.syu.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import java.util.Locale;

//若你想diy一些定制化的功能，只需要写这个组件，然后将它交给SpringBoot
//扩展SpringMVC  dispatchservlet
@Configuration
public class MyMvcConfig implements WebMvcConfigurer {

    //ViewResolver 实现了试图解析器的接口的类，我们就可以把它看作一个视图解析器
    @Bean
    public ViewResolver myViewResolver(){
        return new MyViewResolver();
    }

    public static class MyViewResolver implements ViewResolver{

        @Override
        public View resolveViewName(String s, Locale locale) throws Exception {
            return null;
        }
    }
}
