java - NoMessageBodyWriterFoundFailure : Could not find MessageBodyWriter for response object of type

Question

即使 RESTEasy JAXB jar - resteasy-jaxb-provider.jar 捆绑在 WAR 文件中，我也会收到以下错误

04:52:54,461 ERROR [org.jboss.resteasy.core.SynchronousDispatcher] (default task-1) Failed executing GET /editor/getMetadata/com.karthik.editor.model.EditorAuditEditor: o

我还在我的 WAR 中包含了 jboss-deployment-structure.xml 以排除 JBoss 提供的模块/jars

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
  <deployment>
        <exclude-subsystems>
            <subsystem name="resteasy" />
        </exclude-subsystems>
        <exclusions>
            <module name="javaee.api" />
            <module name="javax.ws.rs.api"/>
            <module name="org.jboss.resteasy.resteasy-jaxrs" />
        </exclusions>
        <local-last value="true" />
    </deployment>
</jboss-deployment-structure>

我已经在 J​​Boss 7 EAP 上部署了 WAR。我目前正致力于将我的应用程序从 JBoss 5 迁移到 JBoss 7。没有代码更改并且在 JBoss5 上运行良好。你能帮忙解决 JBOSS 7 上的这个问题吗？

Answer 1

最后，我找到了解决方案。
问题出在子系统名称上。没有名为“resteasy”的子系统，该子系统实际上名为“jaxrs”。
我更新了 jboss-deployment-structure.xml 中的子系统名称，如下所示:

<exclude-subsystems>
   <subsystem name="jaxrs" />
</exclude-subsystems>
