## 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

<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-log4j2</artifactId>
    		</dependency>
    		
    		
    		<dependency>
    			<groupId>com.fasterxml.jackson.dataformat</groupId>
    			<artifactId>jackson-dataformat-yaml</artifactId>
    		</dependency>

## 二，在工程根目录下添加 lo4g2.yml 配置文件 ##

1， 文件存放位置

3， 在application.yml引入log4j2.yml

## 三， 不同日志枚举类 ##

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zODMxOTQyNQ_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zODMxOTQyNQ_size_16_color_FFFFFF_t_70 3][]

## 四， 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
