带有 javax.ws.rs.core.Application 的 MultiPartFeature答案

【问题标题】：MultiPartFeature with javax.ws.rs.core.Application带有 javax.ws.rs.core.Application 的 MultiPartFeature
【发布时间】：2015-07-28 19:12:58
【问题描述】：

我正在尝试使用 Jersey 上传文件，但遇到了很多麻烦。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。我还尝试添加启用 MultiPart 的 <init-param>，但效果不佳。

我正在使用 Tomcat7，Spring，Jersey 和 Jackson

这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 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。有了这个配置，一切都很好，除了 Multipart

jersey servlet 中的初始化参数。如果我添加这个 init-param 我的休息服务停止工作:(

<servlet-mapping>

    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

【问题讨论】：

您尝试在 javax.ws.rs.Application servlet 定义中添加类名 init-param 吗？还有什么结果表明它不起作用？
对不起，我没有阅读代码中的注释。但是当我在 servlet 定义中设置 init-param 时，它工作正常。没有它，我会得到与您所面临的相同的结果。你能准确地展示你是如何使用 init-param 的吗？也许你放错地方了。
另外，你的 pom.xml 中已经有一个 <jersey.version> 属性。您应该在 <version> 定义中使用它。我看到你在混合版本。您应该使用${jersey.version} 而不是静态版本来保持它们的一致性。实际上，您甚至不需要版本。这就是bom 的用途。你可以完全摆脱 jersey 依赖定义中的版本，一切都一样
@peeskillet 感谢您的帮助。我将如何设置 init-param 放在问题的最后一部分。如果我设置 init-param 我的休息服务停止工作:(
@peeskillet 当我说我的休息服务停止工作时，我的意思是它们都返回 404

【解决方案1】：

是的，原来的 servlet 配置是这样的

<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，您就是在对 Jersey 说：“不要注册您在类路径中找到的所有资源和提供程序，我会自己注册”。

为了解决这个问题，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>

这和扫描类路径不一样，但在大多数情况下，你的所有资源无论如何都应该在你的项目中，如果没有，只需显式注册 jar 包。

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

【讨论】：

我尝试按照你说的添加包扫描，但我遇到了另一个错误。在我添加了这个 init-param 之后，它使实体到 Json 的转换不起作用。在这个link 中，您可以看到我如何配置 Jersey servlet 和异常消息
您可以通过类（到 ...classnames init-param）org.glassfish.jersey.jackson.JacksonFeature（逗号分隔）或注册包 com.fasterxml.jackson.jaxrs.json（在包 init-param 中）注册 JacksonFeature /跨度>
在我也添加了这个包来扫描“org.codehaus.jackson.jaxrs”之后，我的休息服务又可以工作了。现在我要尝试使上传文件正常工作。非常感谢您的帮助！

【解决方案2】：

我认为使用 JSON 作为消费者并将文件作为字节数组传递会更容易，这将使其成为 json 请求的一部分。

【讨论】：

它接缝是一个不错的选择。你能否提供更多细节或提出一些方向。 Tks
