有人可以解释一下这个错误的含义吗？

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

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

                   <version>1.11</version>
                </dependency>

我试着环顾谷歌，但我似乎无法找到原因。

提前致谢！

Answer 1

除去

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

你应该没事。

您通过向类路径添加捆绑包和单独的依赖项来混淆Jersey。所以基本上你有两个具有相同名称的类（在这种情况下为“com.sun.jersey.core.util.FeaturesAndProperties”），Jersey运行时期望一个，你提供第二个......反之亦然。

无论如何，当从类路径中删除jersey-bundle时，你应该没问题。

Answer 2

我在处理分段上传时遇到了类似的问题。经过一些搜索和调查，我发现我使用的是不同版本的jersey-multipart和mimepull jar，它与我项目中使用的球衣束不兼容。

如果您是非maven开发人员，请确保在类路径中添加了以下jar：

jersey-multipart-X.jar
mimepull-Y.jar

X和Y分别是jersey-multipart和mimepull jar的版本标识符。

*请注意X（jersey-multipart的版本）应与jersey-bundle jar的版本相同。
