# 运行环境 #

jdk版本：jdk1.8.0_202
    springboot版本：2.2.0
    mysql版本：5.6.31

# 代码实现 #

1、在pom.xml中添加依赖包

<dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>

2、在需要输出日志的类上加上`@Slf4j`，即可使用`log.info()`打印内容

@Slf4j
    @RestController
    public class SysUserController { 
    
        @RequestMapping("getUserList")
        public Object getUserList(PageEntity page) { 
            log.info("==========获取用户列表(分页)==========");
            PageHelper.startPage(page.getPage(), page.getRows());
            List<SysUser> list = sysUserService.getUserList();
            PageInfo<SysUser> pageInfo = new PageInfo<>(list);
            return ResultsUtils.success(pageInfo.getList(), pageInfo.getTotal());
        }
    
    }

3、在application.properties中添加如下配置，即可在控制台和log文件中输出日志信息

#log配置
    logging.file.name = ./logs/logger.log
    logging.level.root = info

4、控制台和log文件输出效果
