  file:
    name:                         #日志名称，默认为spring.log
    path:                         #日志路径，同时设置name、path，则path失效
    max-size:                     #单个文件最大值，默认为10m
    max-history:                  #日志保存的最长时间，默认为7天
    total-size-cap:               #日志总大小，默认为0表示不设限
    clean-history-on-start: false #启动时是否清除日志，默认不清除
  pattern:
    console:                      #控制台日志输出格式，默认为"%clr(%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"
    file:                         #文件输出格式，默认为"%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } --- [%t] %-40.40logger{39} : %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"
    level:                        #appender的log level输出样式，默认为%5p
    rolling-file-name:            #滚动文件名称，默认为${LOG_FILE} + ".%d{yyyy-MM-dd}.%i.gz"

示例

 

*********************

application.yml

 

logging:
  level:
    com.example.demo.controller.HelloController: debug
  file:
    name: E:\hh\my.log

HelloContrller类的日志输出级别为debug，日志名称为my.log

 

*****************************

controller 层

 

@RestController
public class HelloController {

    Logger logger= LoggerFactory.getLogger(HelloController.class);

    @RequestMapping("/hello")
    public String hello(){
        logger.info("hello {}","world");

        return "success";
    }
}
