Spring运维之boot项目开发关键之日志操作以及用文件记录日志

@RestController
@RequestMapping("/books")
public class Controller {
 
    //创建记录日志的对象
    private static final Logger log= LoggerFactory.getLogger(Controller.class);
 
    @GetMapping
    public String getById(){
        System.out.println("Springboot is running");
 
        log.debug("");//调试
        log.info("");//运行
        log.error("");//报错
        log.warn("");//警告
 
        return  "Springboot is runnning";
    }
 
}

logging:
  level:
    root: debug

package com.bigdata1421.config.controller;
 
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
 
public class BaseClass {
    private Class clazz  ;
    public static Logger log;
    public BaseClass() {
        clazz=this.getClass();
        log=LoggerFactory.getLogger(clazz);
    }
 
}

#设置日志模版格式
pattern:
  console: "%d %clr(%5p) --- [%16t] %clr(%-40.40c){cyan} : %m %n"

logging:
  level:
    root: info
  file:
    name: server.log
  logback:

      file-name-pattern: server.%d{yyyy.MM.dd}.%i.log
