package com.ydfind.start.controller;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**

    @RestController
    @Slf4j
    public class Log4jController {
    
        @GetMapping("/log")
        public String log() {
            log.trace("log name = " + log.getName());
            log.debug("log name = " + log.getName());
            log.info("log name = " + log.getName());
            log.warn("log name = " + log.getName());
            log.error("log name = " + log.getName());
            log.info("log name = " + log.getName());
            return "success";
        }
    }
