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

Question

我正在尝试我的first REST应用程序。

以下是我的配置：

• Java 7

以下是Maven下载的罐子列表：

在服务器启动时，出现以下异常：

根据上面的日志，ApplicationHandler。init（）方法正在调用应用程序。getProperties（）。

ApplicationHandler位于jersey-server-2.22.2中。jar和应用程序在javax中。ws。rs-api-2.0.1，两个JAR都存在于构建路径中。

但我仍然得到了NoSuchMethodError。我查看了以下链接：

• 链接1我没有使用招摇在所有
• 链接2我看不到超过一个版本的应用程序
• 链接3我正在使用JRE 7和JBoss，因为7.1也与JDK 7兼容

因此，我只有一个应用程序包含getProperties（）方法，即使这样，我也得到了NoSuchMethodError。有人能告诉我为什么会这样吗？




Answer 1

正如JBoss As 7文档中提到的，使用的JAX-RS规范的版本是1.1。

因此，为了使用Jsersey 2. X，它提供对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WEB-INF/jboss-deployment-structure.xml来排除与RESTEasy的冲突：

<?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中。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>
