springboot+log4j.yml配置日志文件的方法

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

1. <!-- 配置 log4j2 -->
2. <dependency>
3. <groupId>org.springframework.boot</groupId>
4. <artifactId>spring-boot-starter-log4j2</artifactId>
5. </dependency>
6.  
7. <!-- 加上这个才能辨认到log4j2.yml文件 -->
8. <dependency>
9. <groupId>com.fasterxml.jackson.dataformat</groupId>
10. <artifactId>jackson-dataformat-yaml</artifactId>
11. </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

1. # 共有8个级别，按照从低到高为：ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF。
2. Configuration:
3. status: warn
4. monitorInterval: 30
5. Properties: # 定义全局变量
6. 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：
7. #测试：-Dlog.level.console=warn -Dlog.level.xjj=trace
8. #生产：-Dlog.level.console=warn -Dlog.level.xjj=info
9. - name: log.level.console
10. value: info
11. - name: log.path
12. value: log

63. PatternLayout:

71. # 错误日志
72. - name: EXCEPTION_ROLLING_FILE
73. ignoreExceptions: false
74. fileName: ${log.path}/exception/${project.name}_exception.log
75. filePattern: "${log.path}/exception/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"
76. ThresholdFilter:
77. level: error
78. onMatch: ACCEPT
79. onMismatch: DENY
80. PatternLayout:

90. ignoreExceptions: false
91. fileName: ${log.path}/db/${project.name}_db.log
92. filePattern: "${log.path}/db/$${date:yyyy-MM}/${project.name}-%d{yyyy-MM-dd}-%i.log.gz"

103. level: info
104. AppenderRef:
105. - ref: CONSOLE
106. - ref: ROLLING_FILE

130. # 监听具体包下面的日志
131. # Logger: # 为com.xjj包配置特殊的Log级别，方便调试
132. # - name: com.xjj
133. # additivity: false
134. # level: ${sys:log.level.xjj}
135. # AppenderRef:
136. # - ref: CONSOLE
137. # - 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

1. package com.tcs.irecr.util;
2.  
3. import org.slf4j.Logger;
4.  
5. import org.slf4j.LoggerFactory;
6.  
7. /**
8.  
9. * 本地日志参考类 *
10.  
11. @author Administrator *
12.  
13. */
14.  
15. public class LogUtils {
16. //* 获取业务日志logger
17.  
18. }
19.  
20. public static Logger getBussinessLogger() {
21. return LoggerFactory.getLogger(LogEnum.BUSSINESS.getCategory());
22.  
23. }
24.  
25. //获取平台日志logger
26.  
27. public static Logger getPlatformLogger() {
28. return LoggerFactory.getLogger(LogEnum.PLATFORM.getCategory());
29.  
30. }
31.  
32. //获取数据库日志logger
33.  
34. public static Logger getDBLogger() {
35. return LoggerFactory.getLogger(LogEnum.DB.getCategory());
36.  
37. }
38.  
39. //获取异常日志logger
40.  
41. public static Logger getExceptionLogger() {
42. return LoggerFactory.getLogger(LogEnum.EXCEPTION.getCategory());
43.  
44. }

六， 运行时自动在工程目录下生产日志目录和日志文件
