jboss 服务器无法使用 Log4J 加载 WAR

Question

我正在尝试在本地 jboss EAP 6.1 服务器运行的 Maven 项目中使用 Log4J。这是我的 pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.company</groupId>
    <artifactId>pro</artifactId>
    <version>0.0.2-SNAPSHOT</version>
  </parent>
  <groupId>com.company.test</groupId>
  <artifactId>project</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <name>com.company.test.project</name>

  <dependencies>

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.12</version>
</dependency>

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.5</version>
</dependency>

  </dependencies>

</project>

我有一个 log4j.xml 文件放在 webapp\WEB-INF-classes 下。似乎 jboss 在加载项目时遇到问题，因为 log4j.xml 包含 SMTP 附加程序：

<appender name="EMAIL" class="org.apache.log4j.net.SMTPAppender">
<param name="From"      value="support@company.com"/>
<param name="SMTPHost"  value="smtp1.server.com"/>
<param name="Subject"   value="Fatal Error"/>
<param name="To"        value="user@company.com"/>
<param name="Threshold" value="FATAL" />
</appender>

当我尝试在本地运行项目时，我收到此错误：

编辑：这是我创建的 jboss-deployment-structure.xml 文件：

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
    <deployment>
        <exclusions>
            <module name="org.apache.log4j" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

Answer 1

在 EAP 6.3 中修复了一个错误，该错误将正确的依赖项添加到 EAP 中使用的 log4j 模块。如果您添加以下依赖项$JBOSS_HOME/modules/system/layers/base/org/jboss/log4j/logmanager/main/module.xml，它应该会修复它。

<dependencies>
    <module name="javax.api"/>
    <module name="javax.mail.api" optional="true"/>
    <module name="javax.jms.api" optional="true"/>
    <module name="org.dom4j" optional="true"/>
    <module name="org.jboss.logmanager"/>
    <module name="org.jboss.modules"/>
</dependencies>

另一种选择是使用 jboss-deployment-structure.xml 排除 log4j 并使用您提供的版本。
