java - 部署时错误(java.lang.NoClassDefFoundError : javax/mail/internet/AddressException ) in Jboss 7

Question

我们的项目是在Jetty服务器上运行的，然后这个项目部署在Jboss 7服务器上，但是有一些错误。

我在 E:\jboss-as-7.1.1.Final\standalone\deployments 文件夹中制作 war 文件并复制过去，自动部署开始并给出此错误:

java.lang.NoClassDefFoundError: javax/mail/internet/AddressException

但是在 \WEB-INF\lib 我有 mail.jar 文件..

那么如何消除这个错误呢？

详细错误:

所以请帮忙，如何消除这个错误？

谢谢，

Answer 1

JBoss AS 7 带有独立的类加载，因此您应该仔细配置您的项目依赖项。详情为here .

在你的例子中，我看到 Spring 引用了 JBossAS 提供的 Log4j:Module "org.apache.log4j:main"，并尝试将其配置为执行一些不寻常的事情(可能，试图让日志记录通过电子邮件)。问题是 log4j 模块无法访问 mail-api，因此它会提示。

现在您至少有 3 个解决方案:

1. 让 Spring 只使用 log4j 而无需尝试配置它。而是在应用程序服务器级别配置 log4j。参见 this .请问Spring高手是怎么做的:)

2. 将 log4j.jar 放入您的/WEB-INF/lib 并且不要将 Module "org.apache.log4j" 暴露给您的 webapp。

3. 将 mail-api 暴露给 log4j 模块并从您的应用中删除/WEB-INF/lib/mail.jar。您必须编辑 jboss-as-7.1.1.Final/modules/org/apache/log4j/main/module.xml 以包含对 mail-api 的依赖:

   <dependencies>
       <module name="org.dom4j" optional="true"/>
       <module name="javax.api"/>
       <module name="javax.mail.api" export="true"/>
   </dependencies>
