        </dependency>

spring配置文件添加信息:

log:
  level: INFO
  #日志保存时间（天）
  maxHistory: 7
  #每个日志文件的大小
  maxSize: 10MB

　　

　测试用例

　　包名一定要对,太多logger的包了

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

　　只需要使用对象打印即可在配置文件看到创建的文件

        try {
            logger.info("--------开始执行表KEY_ENTITY_INFO-------------");
            keyEntityInfoService.dealEntityInfo();
        } catch (Exception e) {
            logger.error("--------出现异常KEY_ENTITY_INFO-------------" + e.getMessage());
        }
