分类：综合

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

Properties: # 定义全局变量

Property: # 缺省配置（用于开发环境）。其他环境需要在VM参数中指定，如下：

#测试：-Dlog.level.console=warn -Dlog.level.xjj=trace

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

- name: log.level.console

value: info

- name: log.path

value: log

- name: project.name

value: opendoc

- name: log.pattern

value: "%d{yyyy-MM-dd HH:mm:ss.SSS} -%5p ${PID:-} [%15.15t] %-30.30C{1.} : %m%n"

Appenders:

Console: #输出到控制台

PatternLayout:

pattern: ${log.pattern}

# 启动日志

- name: ROLLING_FILE

fileName: ${log.path}/${project.name}.log

filePattern: "${log.path}/historyRunLog/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

PatternLayout:

pattern: ${log.pattern}

Filters:

# 一定要先去除不接受的日志级别，然后获取需要接受的日志级别

ThresholdFilter:

- level: error

onMatch: DENY

onMismatch: NEUTRAL

- level: info

onMatch: ACCEPT

onMismatch: DENY

Policies:

TimeBasedTriggeringPolicy: # 按天分类

modulate: true

interval: 1

DefaultRolloverStrategy: # 文件最多100个

max: 100

# 平台日志

- name: PLATFORM_ROLLING_FILE

ignoreExceptions: false

fileName: ${log.path}/platform/${project.name}_platform.log

filePattern: "${log.path}/platform/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

PatternLayout:

pattern: ${log.pattern}

- name: BUSSINESS_ROLLING_FILE

ignoreExceptions: false

fileName: ${log.path}/bussiness/${project.name}_bussiness.log

filePattern: "${log.path}/bussiness/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

PatternLayout:

pattern: ${log.pattern}

Policies:

TimeBasedTriggeringPolicy: # 按天分类

modulate: true

interval: 1

DefaultRolloverStrategy: # 文件最多100个

max: 100

# 错误日志

- name: EXCEPTION_ROLLING_FILE

ignoreExceptions: false

fileName: ${log.path}/exception/${project.name}_exception.log

filePattern: "${log.path}/exception/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

ThresholdFilter:

level: error

onMatch: ACCEPT

onMismatch: DENY

PatternLayout:

pattern: ${log.pattern}

Policies:

TimeBasedTriggeringPolicy: # 按天分类

modulate: true

interval: 1

DefaultRolloverStrategy: # 文件最多100个

max: 100

# DB 日志

- name: DB_ROLLING_FILE

ignoreExceptions: false

fileName: ${log.path}/db/${project.name}_db.log

filePattern: "${log.path}/db/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

Loggers:

Root:

level: info

AppenderRef:

- ref: CONSOLE

- ref: ROLLING_FILE

- ref: EXCEPTION_ROLLING_FILE

Logger:

- name: platform

level: info

additivity: false

AppenderRef:

- ref: CONSOLE

- ref: PLATFORM_ROLLING_FILE

- name: bussiness

additivity: false

AppenderRef:

AppenderRef:

additivity: false

AppenderRef:

- ref: DB_ROLLING_FILE

# 监听具体包下面的日志

# Logger: # 为com.xjj包配置特殊的Log级别，方便调试

# - 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());
}
