[置顶] SpringBoot 最简单的日志使用方法

目录

1.maven依赖

<!-- 基础组件-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- @Slf4简化日志 -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>

2.类前加@Slf4j

package com.zk.kfcloud.Controller;

import com.zk.kfcloud.Dao.UserMapper;
import com.zk.kfcloud.Entity.web.User;
import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@Slf4j
@RestController
public class testMyBatis {

@Autowired
private UserMapper userMapper;

@GetMapping("/findAll")
List<User> findall(){
List<User> allUsers = userMapper.findAllUsers();
log.info("info");
log.debug("debug");
log.warn("warn");
log.error("error");
return allUsers;
}
}
