问题描述

我正在尝试我的第一个REST应用程序.

I am trying my first REST application.

下面是我的配置:

  • Java 7
  • JBoss AS 7.1
  • Jersey 2.22.2

以下是Maven下载的jar列表:

Below are list of jars downloaded by Maven:

在服务器启动时，出现以下异常:

On server starting, I am getting the below exception:

21:14:29,013 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/messenger]] (MSC service thread 1-1) StandardWrapper.Throwable: java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;

    at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_79]

根据上述ApplicationHandler.init()方法中的日志，正在调用Application.getProperties().

According to the logs above ApplicationHandler.init() method is calling Application.getProperties().

ApplicationHandler在 jersey-server-2.22.2.jar 中，而Application在 javax.ws.rs-api-2.0.1 中罐子存在于构建路径中.

ApplicationHandler is in jersey-server-2.22.2.jar and Application is in javax.ws.rs-api-2.0.1, both jars are present in build path.

但是我仍然得到NoSuchMethodError.我已经检查了以下链接:

But still I am getting NoSuchMethodError. I have checked below links:

  • 链接1 我根本没有用招摇； /li>
  • 链接2 我看不到一个以上的Application类版本；
  • 链接3 我正在使用JRE 7和JBoss AS 7.1也与JDK 7兼容.
  • link 1 I am not using swagger at all;
  • link 2 I couldn't see more than one version of Application class;
  • link 3 I am using JRE 7 and JBoss AS 7.1 is also JDK 7 compatible.

所以我只有一个应用程序包含getProperties()方法，即使这样我也得到了NoSuchMethodError.有人可以告诉我为什么会这样吗?

So I have only one Application which contains getProperties() method and even then I am getting NoSuchMethodError. Can any one please give me reason why this is happening?

推荐答案

如 JBoss AS 7文档，所使用的JAX-RS规范的版本为1.1.

As mentioned in the JBoss AS 7 documentation, the version of the JAX-RS specification used is 1.1.

因此，为了使用Jsersey 2.X，该版本提供对JAX-RS API的支持并同时提供 JAX-RS 1.x 和 JAX-RS 2.x 参考实现，您需要通过将以下内容添加到您的 WEB-INF/jboss-deployment-structure.xml 中来排除与RESTEasy的冲突:

Therefore, in order to use Jsersey 2.X, which provides support for JAX-RS APIs and serves both JAX-RS 1.x and JAX-RS 2.x reference implementations, you need to exclude the conflicts with RESTEasy by adding the following to your WEB-INF/jboss-deployment-structure.xml:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <!-- Exclude RestEasy conflicts -->
            <module name="javaee.api" />
            <module name="javax.ws.rs.api"/>
            <module name="org.jboss.resteasy.resteasy-jaxrs" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

此外，您需要将以下内容添加到 web.xml :

Also, you need to add the following to your web.xml:

<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>false</param-value>
</context-param>
<context-param>
    <param-name>resteasy.scan.providers</param-name>
    <param-value>false</param-value>
</context-param>
<context-param>
    <param-name>resteasy.scan.resources</param-name>
    <param-value>false</param-value>
</context-param>

相关的JBoss论坛主题如下:

The related JBoss forum threads are the following:

  • Jersey 2 and JBoss 7
  • Jersey application on JBoss AS 7
