我为 spring 3 rest 多部分文件上传做了一个 POC。它工作正常。但是当我尝试与我的应用程序集成时,我遇到了问题。
它抛出以下异常:
org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request;
nested exception is org.apache.commons.fileupload.FileUploadException:
the request was rejected because no multipart boundary was found**"
如果我的代码有任何错误,请告诉我。
bean :
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="order" value="1" />
<property name="mediaTypes">
<map>
<entry key="json" value="application/json" />
<entry key="xml" value="application/xml" />
<entry key="file" value="multipart/mixed" />
</map>
</property>
</bean>
<!-- multipart resolver -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- one of the properties available; the maximum file size in bytes -->
<property name="maxUploadSize" value="50000000" />
</bean>
Controller :
@Controller
public class MultipleFilesRecieve {
@RequestMapping ( value = "/saveMultiple", method = RequestMethod.POST )
public String save( FileUploadForm uploadForm ) {
List<MultipartFile> files = uploadForm.getFiles( );
List<String> fileNames = new ArrayList<String>( );
if ( null != files && files.size( ) > 0 ) {
for ( MultipartFile multipartFile : files ) {
String fileName = multipartFile.getOriginalFilename( );
fileNames.add( fileName );
}
}
return "multifileSuccess";
}
}
最佳答案
问题不在于您的代码,而在于您的请求。您在多部分请求中缺少边界。正如 specification 中所说:
The Content-Type field for multipart entities requires one parameter, "boundary", which is used to specify the encapsulation boundary. The encapsulation boundary is defined as a line consisting entirely of two hyphen characters ("-", decimal code 45) followed by the boundary parameter value from the Content-Type header field.
关于 Spring 休息 : The request was rejected because no multipart boundary was found,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/17462642/
