slf4j/logback: logging日誌的配置

import依賴：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
private static final Logger log = LoggerFactory.getLogger(LoggerTest.class);

package com.muyang.diancan;

import lombok.extern.slf4j.Slf4j;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class LoggerTest {

    private static final Logger log = LoggerFactory.getLogger(LoggerTest.class);

    @Test
    public void test1()
    {
        String name= "zhangsan";
        String password = "123456";

        log.debug("debug:  "+name+",  "+password);
        log.info("info: {}, {}", name, password);
        log.error("error...... ");

    }
}

Slf4j工具

import lombok.extern.slf4j.Slf4j;

package com.muyang.diancan;

import lombok.extern.slf4j.Slf4j;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
public class LoggerTest {

    @Test
    public void test1()
    {
        String name= "zhangsan";
        String password = "123456";

        log.debug("debug:  "+name+",  "+password);
        log.info("info: {}, {}", name, password);
        log.error("error...... ");

    }
}

yml配置方法一

##########################
##logging配置方法一
logging:
  pattern:
    console: "%d - %msg%n"     #日誌輸出格式：日期 - 日誌資訊
  #path: E:\javawork\log
  file: E:\javawork\log\sell.log        #日誌輸出到檔案
  file: E:\javawork\log\sell.%d.log  #日誌輸出到檔案
  level:
    com.muyang.diancan: debug   #指定需要日誌輸出的包:com.muyang.diancan是專案的個根目錄（根包），
