尝试在我的 Jersey3 应用程序（在 tomcat 中运行）中使用 log4j2。我想通过我的 web.xml 加载配置，如下所示：

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!-- ServletContextListeners -->
    <listener>
        <listener-class>com.something.AppContextListener</listener-class>
    </listener>
    
    <!-- Servlets -->
    <servlet>
       ...
    </servlet>

    <!-- Log4J -->
    <context-param>
        <param-name>log4jConfiguration</param-name>
        <param-value>classpath:config/log4j-dev.properties</param-value>
    </context-param>

    <!-- URL-Mapping -->
    <servlet-mapping>
        ...
    </servlet-mapping>

    <!-- Security Roles -->
    <security-role>
      ...
    </security-role>

    <!-- Login Config -->
    <login-config>
        ...
    </login-config>

    <!-- Security Constraints-->
    <security-constraint>
       ...
    </security-constraint>
</web-app>

配置文件本身，位于以下结构中：

src/main/resources/config/

在我的属性中，我定义了一个文件记录器：

log4j-dev.properties

status = warn
name= properties_configuration

property.basePath = ${sys:catalina.home}/logs/ogd_mdd/

# RollingFileAppender will print logs in file which can be rotated based on time or size
appender.rolling.type = RollingFile
appender.rolling.name = fileLogger
appender.rolling.fileName= ${basePath}app.log
appender.rolling.filePattern= ${basePath}app_%d{yyyyMMdd}.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %level [%M] [%l] - %msg%n

# Configure root logger for logging error logs in classes which are in package other than above specified package
rootLogger.level = info
rootLogger.appenderRef.rolling.ref = fileLogger

pom.xml

        <!-- Logging -->
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>${log4j2.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>${log4j2.version}</version>
        </dependency>
        <dependency>

            <artifactId>log4j-web</artifactId>
            <version>${log4j2.version}</version>
        </dependency>

我得到的只是错误级别的控制台日志（似乎加载了默认配置而不是我的）。我确定，我正确定义了配置，尽管在 web.xml 中犯了一个错误...我需要如何定义路径才能正确加载属性？

您使用了错误的log4jConfiguration参数值：file:///config/log4j-dev.properties指向/config/log4j-dev.properties本地文件系统的文件。

由于log4jConfiguration可以是要传递到的资源路径ServletContext#getResource或绝对 URI，因此您可以使用：

  • 文件相对于 Web 应用程序根目录的路径：/WEB-INF/classes/config/log4j-dev.properties,
  • 类路径 URI: classpath:config/log4j-dev.properties.

编辑：您的配置也有一点问题：它缺少触发策略：

status = warn
name= properties_configuration

property.basePath = ${sys:catalina.base}/logs/ogd_mdd/

# RollingFileAppender will print logs in file which can be rotated based on time or size
appender.rolling.type = RollingFile
appender.rolling.name = fileLogger
appender.rolling.fileName= ${basePath}app.log
appender.rolling.filePattern= ${basePath}app_%d{yyyyMMdd}.log.gz
appender.rolling.policy.type = TimeBasedTriggeringPolicy
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} %level [%M] [%l] - %msg%n

# Configure root logger for logging error logs in classes which are in package other than above specified package
rootLogger.level = info
rootLogger.appenderRef.rolling.ref = fileLogger
