我正在使用Jersey 1.11 + Jetty 7.6.1.v20120215. 这些是我的依赖项:

I am using Jersey 1.11 + Jetty 7.6.1.v20120215. These are my dependencies:

                </dependency>

我尝试环顾Google，但似乎找不到原因.

I tried looking around Google, but I couldn't seem to find the cause.

提前谢谢！

推荐答案

删除

   <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-bundle</artifactId>
        <version>1.11</version>
   </dependency>

你应该没事.

通过将捆绑包和单独的依赖项添加到类路径中，使Jersey感到困惑.因此，基本上，您有两个具有相同名称的类(在本例中为"com.sun.jersey.core.util.FeaturesAndProperties")，Jersey运行时期望一个，而您要提供第二个.反之亦然.

You are confusing Jersey by adding bundle and separate dependencies to the classpath. So basically you have two classes which have same name ("com.sun.jersey.core.util.FeaturesAndProperties" in this case), Jersey runtime expects one and you are providing second one.. or vice versa.

无论如何，当从类路径中删除jersey-bundle时，您应该没事.

Anyway, you should be fine when jersey-bundle is removed from classpath.
