我没有发现问题所在，在添加最后 3 个依赖项后，我无法访问我的任何资源 project.Even 如果我没有上传文件并尝试访问除此之外的资源然后我收到这个错误。请帮我解决这个问题。

Answer 1

不要混用 Jersey Major 版本。它们不兼容，即

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.8</version>
</dependency>

<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-multipart</artifactId>
    <version>1.8</version>
</dependency>

摆脱那两个。对于多部分支持，请改用

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.16</version>
</dependency>

这是球衣 2.x 支持。然后你需要注册MultiPartFeature。这取决于您如何配置您的应用程序，以及如何完成。这些链接可能会有所帮助：, link,
