轻松自如，文件上传：无内容处理错误

问题描述

|| 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) {
     }

我已经使用SOAPUI，curl和HTML表单来测试此代码，对于所有这些我都遇到相同的错误：在零件内找不到Content-disposition标头

我正在使用JBoss AS 6和resteasy。我不明白为什么会收到此错误或如何解决它。     

解决方法

尝试使用resteasy和我的Seam框架时，出现了相同的错误。 该错误的原因是Seam MultipartFilter捕获了该请求。我什么 要做的是告诉Seam MultipartFilter仅处理以结尾的多部分请求 *。接缝。 这样，resteasy达到了预期的要求，而不是接缝过滤器。 我的休息方法：

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

上传表格：

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，我也将开始查看您正在使用的框架并找出首先处理您的请求的地方。     ,使用Resteasy和Spring Boot我遇到了相同的错误。 Spring MVC默认不配置ѭ5，但Spring Bootѭ6配置。 只需将以下内容添加到ѭ7中，即可禁用Spring Boot想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
