我在RabbitMQ Project中有pom.xml。附上示例代码。任何人都可以帮我解决我面临的错误。我尝试在网上实施各种解决方案但没有成功。我也尝试过使用Log4J xml。
我在许多网站上看到如果我使用log4j，那么我也必须排除一些依赖。在我的pom xml中我排除了它们。但仍然没有成功。

答案 0 :(得分：0)
错误的原因是log4j-core version 2.5没有以下方法 -
org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(org.apache.logging.log4j.core.LoggerContext loggerContext, org.apache.logging.log4j.core.config.ConfigurationSource configurationSource)
要解决此错误，只需从pom.xml -
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.5</version>
</dependency>
让Spring boot管理log4j个依赖关系及其版本。有关信息，Spring boot version 1.5.3.RELEASE使用log4j version 2.7，此版本具有上述方法。
