xml - wildfly 不从 web.xml 加载类

Question

无法运行 war ，因为我在 wildfly 中配置了所有模块， 这场 war 在具有相同 web.xml 配置的 jboss 6 中运行良好，当我在所有迁移设置之后部署在 wildfly 中时，我得到 classNotFound 异常，因为我在 web.xml 中几乎没有 servlet 映射

更多信息请在下面找到

在 Wildfly 中低于异常:

这里是 web.xml

这是我的日志:

Answer 1

您的类 com.Test.us.web.MessageFilter 似乎对类加载器不可见。您可以在 2 个选项中放置类:

1. 直接在WAR中部署

   • 要么在 WEB-INF/lib/some.jar
   • 或扩展到WEB-INF/classes

2. 在自定义 WildFly 模块中。在这种情况下，您必须将模块依赖项添加到部署中。可以在以下文件中定义模块依赖项:

   • META-INF/MANIFEST.MF
   • 或在 META-INF/jboss-deployment-structure.xml

jboss-deployment-structure.xml 文件的示例内容是:

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="your.custom.module"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
