一,Maven 依赖 pom.xml配置
1, 去掉默认日志,以便切换到log4j2的日志依赖
2, 然后添加如下两个日志依赖
二,在工程根目录下添加 lo4g2.yml 配置文件
2, 配置文件内容
- <!-- 配置 log4j2 -->
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-log4j2</artifactId>
- </dependency>
- <!-- 加上这个才能辨认到log4j2.yml文件 -->
- <dependency>
- <groupId>com.fasterxml.jackson.dataformat</groupId>
- <artifactId>jackson-dataformat-yaml</artifactId>
- </dependency>
三,在工程根目录下添加 lo4g2.yml 配置文件
1, 文件存放位置
2, 配置文件内容
- # 共有8个级别,按照从低到高为:ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF。
- Configuration:
- status: warn
- monitorInterval: 30

- #生产:-Dlog.level.console=warn -Dlog.level.xjj=info

- Loggers:

- # 监听具体包下面的日志

- # - name: com.xjj
- # additivity: false
- # level: ${sys:log.level.xjj}
- # AppenderRef:
- # - ref: CONSOLE
- # - ref: ROLLING_FILE
3, 在application.yml引入log4j2.yml
四, 不同日志枚举类
五, 不同日志工具类util编辑
- package com.tcs.irecr.util;
- import org.slf4j.Logger;
- import org.slf4j.LoggerFactory;
- /**
- * 本地日志参考类 *
- @author Administrator *
- */
- public class LogUtils {
- //* 获取业务日志logger
- }
- public static Logger getBussinessLogger() {
- return LoggerFactory.getLogger(LogEnum.BUSSINESS.getCategory());
- }
- //获取平台日志logger
- public static Logger getPlatformLogger() {
- return LoggerFactory.getLogger(LogEnum.PLATFORM.getCategory());
- }
- //获取数据库日志logger
- public static Logger getDBLogger() {
- return LoggerFactory.getLogger(LogEnum.DB.getCategory());
- }
- //获取异常日志logger
- public static Logger getExceptionLogger() {
- return LoggerFactory.getLogger(LogEnum.EXCEPTION.getCategory());
- }
六, 运行时自动在工程目录下生产日志目录和日志文件
