我尝试添加 log4j2 以便我可以配置日志记录模式和 ELK 转发。但我无法那样做。

这是我实施的

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</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>

尝试添加 log4j2.properties 或 log4j2.xml 它们都不起作用。

你能建议任何方法来实现这一目标吗？

谢谢

【问题讨论】：

试过了不工作logback-spring.xml
您将依赖项放在哪里：project/dependencies 或 project/dependencyManagement/dependencies？您的依赖关系树没有考虑到它们。

标签： java spring spring-boot maven log4j2

【解决方案1】：

对于日志记录配置，请尝试application.properties => logging.config = classpath:log4j2.xml

对于 ELK 日志记录模式，您尝试过 Slf4J + LogBack 吗？（Slf4J+LogBack 是默认的 Spring 设置）

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
   <groupId>net.logstash.logback</groupId>
   <artifactId>logstash-logback-encoder</artifactId>
</dependency>
