NoSuchMethodError javax.ws.rs.core.Application.getProperties()Ljava/util/Map

Question

我正在尝试我的第一个 REST 应用程序。

以下是我的配置：

Java 7
JBoss 作为 7.1
泽西岛 2.22.2

以下是 Maven 下载的 jar 列表：

服务器启动时，出现以下异常：

根据上面的日志，ApplicationHandler.init() 方法正在调用 Application.getProperties()。

ApplicationHandler 在 jersey-server-2.22.2.jar 并且 Application 在 javax.ws.rs-api-2.0.1，两个 jar 都存在于构建路径中。

但我仍然得到 NoSuchMethodError。我检查了以下链接：

我根本没有使用 swagger；
link 2 我看不到一个版本的 Application class;
我正在使用 JRE 7，JBoss AS 7.1 也与 JDK 7 兼容。

所以我只有一个 Application，其中包含 getProperties() 方法，即便如此我也得到了 NoSuchMethodError。任何人都可以告诉我发生这种情况的原因吗？

Answer 1

如JBoss AS 7 documentation中所述，使用的JAX-RS规范版本为1.1。

因此，为了使用 Jsersey 2.X，它提供对 JAX-RS API 的支持并提供两个 JAX-RS 1.x and JAX-RS 2.x 参考实现，您需要通过添加以下内容来排除与 RESTEasy 的冲突你的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您的 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>
