版本

Library	Current	Upgraded
Lo4j2 related jar	*	2.17.1

1. 如果你用的是spring boot2.x 怎么升级方便

在pom.xml里加log4j2.version属性, 覆盖掉spring-boot-starter-parent的指定版本。

 <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.2</version><relativePath/> <!-- lookup parent from repository --></parent><properties> <log4j2.version>2.17.1</log4j2.version>
</properties>

原因是：

spring-boot-dependendencies.pom里定义了 log4j2.version属性，利用它的值加的log4j2相关的包。

.... <groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>2.6.2</version><packaging>pom</packaging>
...<properties>
...<log4j2.version>2.17.0</log4j2.version><logback.version>1.2.9</logback.version><lombok.version>1.18.22</lombok.version><slf4j.version>1.7.32</slf4j.version>
...</properties><dependencies><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-bom</artifactId><version>${log4j2.version}</version><type>pom</type><scope>import</scope></dependency></dependencies>

在 log4j-bom.pom 里其实它把所有的log4j相关包都加了。所以在我们的项目你直接用就可以了。

  <groupId>org.apache.logging.log4j</groupId><artifactId>log4j-bom</artifactId>
....<dependencyManagement><dependencies><!-- Log4j API --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-api</artifactId><version>${project.version}</version></dependency><!-- Core Log4j --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-core</artifactId><version>${project.version}</version></dependency>.....<!-- Legacy Log4j 1.2 API --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-1.2-api</artifactId><version>${project.version}</version></dependency><!-- Commons Logging Compatibility API --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-jcl</artifactId><version>${project.version}</version></dependency><!-- SLF4J Compatibility API --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-slf4j-impl</artifactId><version>${project.version}</version></dependency><!-- SLF4J 1.8.x Compatibility API --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-slf4j18-impl</artifactId><version>${project.version}</version></dependency><!-- SLF4J Adapter --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-to-slf4j</artifactId><version>${project.version}</version></dependency><!-- Web Application Support --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-web</artifactId><version>${project.version}</version></dependency><!-- java.util.logging adapter --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-jul</artifactId><version>${project.version}</version></dependency>....</dependencies></dependencyManagement>

如果你不是很了解 <scope>import</scope>的含义，可以看看下面的介绍，讲的很清楚

2. Caused by: java.lang.NoSuchMethodError: com.lmax.disruptor.dsl.Disruptor

异常信息：

Caused by: java.lang.NoSuchMethodError: com.lmax.disruptor.dsl.Disruptor.<init>(Lcom/lmax/disruptor/EventFactory;ILjava/util/concurrent/ThreadFactory;Lcom/lmax/disruptor/dsl/ProducerType;Lcom/lmax/disruptor/WaitStrategy;)V

原因：

项目使用了log4j2，由于使用了全局异步打印日志的方式，还需要引入disruptor的依赖

<dependency><groupId>com.lmax</groupId><artifactId>disruptor</artifactId><version>3.2.0</version>
</dependency>

log4j2.xml

 <Loggers><AsyncRoot level="INFO" includeLocation="true"><AppenderRef ref="stdout" /><AppenderRef ref="file" /></AsyncRoot></Loggers>

解决方法：

升级Disruptor 到3.4.0 版本

<dependency><groupId>com.lmax</groupId><artifactId>disruptor</artifactId><version>3.4.0</version>
</dependency>
