JBOSS 7.1.0错误 - 无法找到类org.jboss.resteasy.core.AsynchronousDispatcher的公共构造函数

标签： java spring resteasy jboss7.x

我正在尝试将基于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：

错误没有任何意义，我唯一能认识到的是RESTEasy服务servlet名称。这配置如下 - 在Jboss 7.0.2

中工作正常 
<servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

4 个答案:

答案 0 :(得分：26)

在JBoss 7.1.1（没有Spring）上使用RESTEasy时，我也看到了这个异常。它包裹得像这样：

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RESTEasy罐子。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依赖项来实现此目的，因为这些是由JBoss提供的，并且不包括任何传递的RESTEasy依赖项（例如，请参阅this link）。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，您可能还需要切换到演示in the RESTEasy docs的基于类的方法。 RESTEasy开发人员here和here提及了这个问题的解决方案。

答案 1 :(得分：5)

我远不是REST专家，但javax.ws.rs.core.Application不是servlet。

答案 2 :(得分：2)

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没什么关系!!），但这是JBoss中的一个错误，你需要在里面指定RESTful资源一个Application子类，否则它将尝试将AsyncDisp ***挂载为RESTful服务。

答案 3 :(得分：1)

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<Object> singletons = new HashSet<Object>();

public RESTApplication () {
    singletons.add(new RestService());
}

@Override
public Set<Object> getSingletons() {
    return singletons;
}

}

第2步：编辑您的web.xml 

<!-- Resteasy -->
<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
</context-param>

<servlet>
    <servlet-name>resteasy-servlet</servlet-name>
    <servlet-class>
        org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
            </servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>yourpackage.RESTApplication</param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>resteasy-servlet</servlet-name>
    <url-pattern>/rest/*
    </url-pattern>
</servlet-mapping>
