javax.ws.rs.core.Application 的 MultiPartFeature

Question

我正在尝试使用 Jersey 上传文件，但我遇到了很多麻烦。我看到我必须配置 MultiPartFeature 才能让事情发生，但我无法让它工作。我知道我必须在球衣上启用多部分功能，但这就是问题所在。

我尝试配置自定义应用程序 ResourceConfig 但由于某些原因，当我这样做时，我的其余服务停止工作。我还尝试添加一个 <init-param> 启用 MultiPart 但效果不佳。

我正在使用 Tomcat7，Spring，Jersey with Jackson

这些是我尝试过的几种方法。

Uploading file using Jersey over RESTfull service and The resource configuration is not modifiable?

我正在使用默认的 servlet 配置 javax.ws.rs.core.Application 来映射我的其余服务。我想这就是整个问题，但正如我之前提到的，当我尝试映射自定义 Application ou ResourceConfig 时，我遇到了其他问题

这是我当前的配置。使用此配置，除了 Multipart

之外，一切都很好

</servlet>

<servlet-mapping>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

Answer 1

我认为您使用 JSON 作为消费者并以字节数组形式传递您的文件会更容易，这将使它成为您 json 请求的一部分。

Answer 2

是的，所以您拥有的原始 servlet 配置

<servlet>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <load-on-startup>1</load-on-startup>
</servlet>

允许通过类路径扫描注册类。添加 <init-param> ...provider.classnames 后，您对 Jersey 说，"don't register all those resources and providers you found on the classpath, I will register them myself".

所以要解决这个问题，您可以添加 <init-param> 来扫描您的项目包，或类路径上的任何其他包（如其他 jar）。

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>
        the.packages.to.scan,
        multiple.pacakges,
        can.be.separated.by.comma
    </param-value>
</init-param>

这与扫描类路径不同，但在大多数情况下，您的所有资源无论如何都应该在您的项目中，如果没有，只需显式注册 jar 包即可。

一般情况下，请参阅 Application Deployment 了解其他部署模式和配置
