如何在Spring Boot中使用Log4J2复合配置

我正在通过以下POM将Spring Boot" title="Spring Boot">Spring Boot 2.0.1入门版与log4j2一起使用。WAR文件托管在Tomcat

8中（而不是使用嵌入式tomcat）。应用程序日志将写入控制台，而不是写入日志文件。显然，Spring Boot的XML配置将覆盖应用程序中配置的XML。

POM：

<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>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-web</artifactId>
    </dependency>

Log4j2使用复合配置，其中配置分为2个xml文件：log4j2-base.xml和log4j2-env.xml

资源目录包含log4j2.component.properties以下内容：

log4j.configurationFile=log4j2-base.xml,log4j2-env.xml

资源目录还包含log4j2-base.xml。文件log4j2-env.xml是特定于环境的JAR文件的一部分，该文件已放置在类路径中。

回答：

我们尝试了以下方法，并且有效：

  1. 将文件log4j-base.xml重命名为log4j2.xml

  2. 在log4j2.component.properties中，将log4j-base.xml重命名为log4j2.xml，如下所示：

log4j.configurationFile = log4j2.xml，log4j2-env.xml
