JBOSS 7.1.0错误 – 无法找到类org.jboss.resteasy.core.AsynchronousDispatcher的公共构造函数
我正在尝试将我的基于Spring MVC的REST应用程序迁移到Jboss 7.1.0。 在启动时，Jboss初始化显示一切都已正确启动，所有war文件都已成功部署。
我在Spring MVN和Jboss的RestEasy服务之间进行集成时遇到了很多问题，我想知道这是否是jboss resteasy与Spring MVN之间的另一个冲突。
当我向REST服务发出请求时，我收到以下错误：

这配置如下 – 在Jboss 7.0.2中工作正常
javax.ws.rs.core.Application /rest/*
我远不是REST专家，但javax.ws.rs.core.Application不是servlet。
在JBoss 7.1.1（没有Spring）上使用RESTEasy时，我也看到了这个exception。 它被包裹得像这样：
Allocate exception for servlet [project class reference]: java.lang.RuntimeException: Unable to find a public constructor for class org.jboss.resteasy.core.AsynchronousDispatcher
解决方案是从战争中排除所有RESTEasyjar子。 在Maven中，您可以通过确保使用Maven的“提供”范围声明任何所需的RESTEasy依赖关系来实现此目的，因为这些是由JBoss提供的，并且不包括任何传递的RESTEasy依赖关系（请参阅此链接以获取示例）。 您可以通过更改到包含pom.xml的目录并发出如下命令来检查是否有任何RESTEasy依赖项：
mvn dependency:tree | grep "resteasy"
如果您使用web.xml进行JAX-RS激活，则可能还需要切换到RESTEasy文档中演示的基于类的方法。 RESTEasy开发人员在这里和这里提到了这个问题的解决方案。
问题不在于声明RESTful服务的方式，这种方式对于JAX-RS 1.1来说是非常标准的（与Servlet James没有任何关系!!），但它是JBoss中的一个错误，您需要在Application子类中指定RESTful资源，否则它会尝试将AsyncDisp ***挂载为RESTful服务。
我通过执行以下步骤解决了这个问题：
步骤1.创建服务注册类
public class RESTApplication extends javax.ws.rs.core.Application { private Set
}
第2步：编辑您的web.xml
resteasy.servlet.mapping.prefix /rest resteasy-servlet org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher javax.ws.rs.Application yourpackage.RESTApplication resteasy-servlet /rest/*
