springboot——配置默认访问登陆页

spring boot 配置默认访问登陆页

1、需要两个依赖

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>

2、WebMvcConfg

package com.example.demo.configuration;
import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * 设置自动跳转登陆页
 */
@Configuration
public class WebMvcConfg implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("login");
    }
}

3、页面应放在thymeleaf默认文件夹templates下
