springboot整合log4j
1、依赖添加
1.1、添加依赖
需要引入 log4j
的依赖支持,推荐自己确定使用的版本。
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-to-slf4j</artifactId>
<version>2.11.2</version>
</dependency>
1.2、剔除依赖
springboot
默认自己内部添加了对日志的支持,需要将其全部剔除掉,不然会影响 log4j
的依赖使用。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
<exclusions>
<exclusion>
<groupId>*</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
</dependency>
2、配置日志
2.1、日志打印记录
根据自己的需求进行相关的配置,这里需要注意的是使用 xml
文件进行配置,使用 properties
有坑没爬起来,文件名自定义,没有啥要求,都会在配置文件中进行指定的。
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="10 seconds">
<contextName>beordie</contextName>
<property name="path" value="E:\\file\\javalearn\\blog\\src\\main\\resources\\logs" />
<conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" />
<conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
<conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />
<property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>

<appender-ref ref="DEBUG_FILE" />
<appender-ref ref="INFO_FILE" />
<appender-ref ref="WARN_FILE" />
<appender-ref ref="ERROR_FILE" />
</root>
</configuration>
2.2、指定配置文件
还需要在 spring boot
的项目配置文件中进行配置的指定。
logging:
config: classpath:log4j.xml
到这里完成对日志的整体配置,启动项目通过下面语句拿到日志对象即可进行日志的打印输出。
private final Logger LOGGING = LoggerFactory.getLogger(ArticleController.class);
