先引入Logger和LoggerFactory:

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

声明logger作为成员变量,并且初始化:

private static Logger logger = LoggerFactory.getLogger(TestDemo.class);

在方法中使用:

logger.info("===发送消息通知===originDocKey:" + originDocKey);

测试代码:

package com.jawasoft.testDemo;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class TestDemo {
    private static Logger logger = LoggerFactory.getLogger(TestDemo.class);

    @Test
    public void test4(){
        logger.info("开始");
        System.out.println("================================");
        logger.info("结束");
    }
}

控制台打印日志如下:

2020-10-30 17:29:10 CST INFO  com.jawasoft.testDemo.TestDemo 101 test4 - 开始[]
================================
2020-10-30 17:29:10 CST INFO  com.jawasoft.testDemo.TestDemo 103 test4 - 结束[]

 还可以加error类型的日志,如下:

String fileName = fileEntity.getFileName();
if (null == fileName || ("").equals(fileName.trim())) {
   logger.error("No FileName Found.");
   throw new Exception("No FileName Found.");
}
