Resteasy 和文件上传：没有出现内容处置错误

Question

我有一个可以上传文件的休息资源。

   @Path("/rest/input")
   public class InputResourceBean {

     @POST
     @Path("{directory: .*}")
     @Consumes("multipart/form-data")
     public void post(final String directory, final MultipartFormDataInput input) {
     }

部分中找不到 Content-Disposition 标头

我使用 SOAPUI、curl 和 HTML 表单来测试此代码，对于所有这些代码，我都得到相同的错误：在我使用 JBoss AS 6 和 Resteasy 的 。我不明白为什么会出现此错误或如何解决它。

Answer 1

当我尝试使用resteasy 时，在我的例子中，Seam 框架出现了同样的错误。
错误的原因是Seam MultipartFilter捕获了请求。我什么
所要做的就是告诉 Seam MultipartFilter 仅处理以以下结尾的多部分请求
*。接缝。

这样 Resteasy 就得到了预期的请求，而不是接缝过滤器。

我的休息方法：

@POST
@Path("admin/uploadImage")
public String uploadImage(@MultipartForm UploadForm form);

上传表单：

public class UploadForm {

    private byte[] filedata;

    public UploadForm() {
    }

    public byte[] getFileData() {
        return filedata;
    }

    @FormParam("filedata")
    @PartType("application/octet-stream")
    public void setFileData(final byte[] filedata) {
        this.filedata = filedata;
    }


}

components.xml：

    <component class="org.jboss.seam.web.MultipartFilter">
        <property name="createTempFiles">true</property>
        <property name="maxRequestSize">8000000</property>
        <property name="urlPattern">*.seam</property>
    </component>

即使您可能不使用 Seam，我也会开始查看您正在使用的框架，并且找出您的请求首先在哪里得到处理。

Answer 2

我使用 Resteasy 和 Spring Boot 遇到了同样的错误。

Spring MVC 不配置 MultipartResolver 默认情况下，但是 Spring Boot MultipartAutoConfiguration确实。

只需将以下内容添加到您的 application.yml 即可禁用 Spring Boot 要配置的多部分解析器：

spring.http.multipart.enabled: false

如果您使用的 Spring Boot 版本低于 1.4：

multipart.enabled: false
