STS 不选择 log4j.xml 或 log4j2.properties 写入文件答案

【问题标题】：STS not picking log4j.xml nor log4j2.properties to write in fileSTS 不选择 log4j.xml 或 log4j2.properties 写入文件
【发布时间】：2022-01-05 16:29:58
【问题描述】：

我们正在迁移到 log4j2.xml 作为 log4j2 漏洞的一部分。但是新创建的 log4j2 在应用程序启动期间没有被拾取。我已经执行了以下所有选项，但都是徒劳的。

尝试的选项：

尝试添加和删除 log4j-jcl 依赖项。
删除了 spring-boot-starter-logging 依赖项。
尝试使用 log4j2.properties 而不是 log4j2.xml。
在 application.properties 中添加了 logging.config 属性。
尝试重命名 RollingFile 名称并故意提供不正确的 AppenderRef ref 以检查任何与 bean 相关的异常。但应用程序已成功启动。这意味着这个 log4j2.xml 和 log4j2.properties 文件没有被拾取。

这是我的项目的详细信息。如果需要任何其他信息，请告知。

log4j2.xml：

【问题讨论】：

标签： java spring-boot spring-mvc

【解决方案1】：

XML 配置文件应该放在 src/main/resources 文件夹下。

【讨论】：

是的。它位于所提到的确切位置。

【解决方案2】：

您的 Spring Boot 项目继承自 Spring Boot Starter 父项目，该项目依赖于 SLF4J 和 logback。你可以将你的项目迁移到 logback 或者你应该删除 logback 依赖项。

要删除 logback 依赖项，请尝试更新您的 POM 文件：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

【讨论】：

接收转换异常：Exception in thread "main" java.lang.ExceptionInInitializerError at com.proj.ds.mdm.grouping.batch.ProcessorBatchApp.main(ProcessorBatchApp.java:16) Caused by: org.apache.logging.log4j.LoggingException: log4j-slf4j-impl cannot be present with log4j-to-slf4j

【解决方案3】：

另外，由于 Spring Boot Starter 集成了 Logback，请考虑从 log4j 迁移到 Logback。 https://logback.qos.ch/manual/introduction.html.

Logback 是由 log4j 的创始人设计的。

这里有一个迁移工具：https://www.slf4j.org/migrator.html
