java - 带有 javax.ws.rs.core.Application 的 MultiPartFeature

标签 java web-services rest jersey tomcat7

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让事情发生，但我无法让它发挥作用。我知道我必须在 Jersey 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但出于某种原因，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 但效果不佳。

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?

我正在使用默认的 servlet 配置 javax.ws.rs.core.Application映射我的休息服务。我想这就是整个问题，但正如我之前在尝试映射自定义 Application ou ResourceConfig 时提到的那样我遇到了其他问题

这是我当前的配置。使用此配置，除了 Multipart 之外，一切都很好

接收上传文件的服务

    private MigracaoGenericService migracaoGenericService;

    @Autowired
    private UsuarioController usuarioController;

}

在 jersey servlet 中初始化参数。如果我添加这个初始化参数，我的其余服务将停止工作:(

    <servlet>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <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>

最佳答案

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来注册类。添加 <init-param> 后...provider.classnames ，你是在对 Jersey 说，“不要注册你在类路径上找到的所有那些资源和提供者，我会自己注册它们”。

所以要解决这个问题，您可以添加 <init-param>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。
