JAX-RS：NoSuchMethodFound Exception Jersey-media-moxy JSON

Question

我一直在努力工作几个小时。我正在用Jersey-RS制作球衣。一切都很顺利，直到我不得不在一个地方返回JSON。我知道必须有一个jersey-media-moxy库才能将Java对象绑定到JSON格式。我从Jersey-media-moxy到Google的genson库一个接一个地下载了几个JSON库。但还没有成功。使用我从http://www.java2s.com/Code/Jar/j/Downloadjerseymediamoxy23jar.htm下载的Jersey-media-moxy，运行Web服务时出现以下错误。

如果我用SEVERE: StandardWrapper.Throwable java.lang.NoSuchMethodError: org.glassfish.jersey.internal.util.PropertiesHelper.getValue(Ljava/util/Map;Ljavax/ws/rs/RuntimeType;Ljava/lang/String;Ljava/lang/Object;Ljava/lang/Class;)Ljava/lang/Object;

这是一个非maven项目，我通过Project-＆gt;添加了罐子。属性。 我尝试了其他JSON库，如 Jetty，Jackson ，但没有一个工作过。 Jersey-media-moxy 以外的库会使 MessageBodyWriter找不到异常。我做错了什么？它与家属有关吗？这是我的项目结构：

在这方面的任何帮助将受到高度赞赏。 在此先感谢。

Answer 1

我一直遇到同样的问题，花了我很长时间才能摆脱掉。

此问题的基本问题是缺少jersey-media-moxy-2.27.jar请求的几个jar jersey-media-moxy-2.27 jar在运行时内部使用了一些其他API。

要解决此问题，请参考随附的快照，并确保项目中包含所有jar（版本很重要） image

建议：如果您正在使用Eclipse IDE，并且认为服务器是“已启动”，请尝试在启动服务器（在本例中为它的Tomcat）时查看控制台日志。不应有任何错误消息。

Answer 2

确保你的jersey.media jar与其他jersey jar完全相同

compile "org.glassfish.jersey.media:jersey-media-json-jackson:{$version}

所有罐子的

$ version应该是相同的

Answer 3

就我而言，它的发生是由于：

<dependency>
    <groupId>org.glassfish.jersey.connectors</groupId>
    <artifactId>jersey-apache-connector</artifactId>
    <version>${jersey.version}</version>
</dependency>

其中 $ {jersey.version} 与其他球衣依赖项不同
