Question

我尝试使用Jersey上传文件，但我遇到了很多麻烦。我看到我必须配置MultiPartFeature以使事情发生但我无法使其发挥作用。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和ResourceConfig，但由于某种原因，当我这样做时，我的休息服务停止工作。我还尝试添加<init-param>启用MultiPart，但也没有。

我正在使用Tomcat7，Spring，Jersey和Jackson

这些是我尝试过的几种方法。

org.glassfish.jersey upload file with FormDataContentDisposition

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

我使用默认的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

这是我目前的配置。使用此配置，一切都很好，除了Multipart

泽西servlet中的初始化参数。如果我添加此init-param，我的其他服务将停止工作：（

    <init-param>

        <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
    </init-param>
</servlet>

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

Answer 1

是的，你有原始的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。一旦你添加了<init-param> ...provider.classnames，你就会对泽西说：“不要注册你在类路径上找到的所有资源和提供者，我会自己注册”。

因此，为了解决这个问题，您可以添加<init-param>来扫描项目包，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，所有资源都应该在项目中，如果没有，只需显式注册jar包。

通常，请参阅Application Deployment了解其他部署模式和配置

Answer 2

我认为使用JSON作为使用者更容易，并将文件作为字节数组传递，这将使其成为json请求的一部分。
