# 直接在代码中使用 #

package com.zz.controller;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @Slf4j
    public class LogBackController {
        @GetMapping("/logtest1")
        public String test1(){
            log.debug("debug测试日志消息");
            log.info("info 测试日志信息");
            log.error("info 测试日志信息");
            log.warn("warn 测试日志信息");
            return "ok";
        }
    }
