使用ExtJS和Jersey上传文件
我有一个基于ExtJS的应用程序,我想通过Rest的Jersey来上传一个文件,一张图片,但是我不能这么做,这有可能吗? 这是我的代码的一部分:
视图:
.
.
.
items: [{
xtype: 'filefield',
name: 'iconBmp',
fieldLabel: this.i18nColIconBmp,
enforceMaxLength : true,
labelWidth: 100,
msgTarget: 'side',
anchor: '100%',
buttonText: 'Exam'
}],
buttons: [{
text: 'Upload',
handler: function() {
var form = this.up('form').getForm();
if (form.isValid()) {
form.submit({
url: 'icon/upload',
waitMsg: 'Uploading...',
success: function(fp, o) {
Ext.Msg.alert('Success', o.result.file + ' has been uploaded.');
}
});
}
}
}]
Java的:
@Path("icon")
public class CatIconRest {
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFIle(
@FormDataParam("file") InputStream uploadedInputStream,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String string = fileDetail.getFileName();
System.out.println(string );
// TODO:
return null;
}
}
问题是,我从来没有去过Java类,ExtJS形式不发送任何东西,我必须改变/添加?
如果你需要更多的代码,请问。
提前致谢!
编辑:我正在测试它与称为邮递员的铬扩展,这些是请求的配置:
邮差测试:
Accept: application/json
Content-type: multipart/form-data
Cache-Control: no-cache
Url: http://localhost/app/icon/upload
Method: POST
File: Mine.doc
我在项目中添加了一些jar,jersey-multipart-1.17.1.jar和mimepull-1.9.3.jar,但我无法用扩展名测试它,这就是我得到的结果:
A message body reader for Java class com.sun.jersey.core.header.FormDataContentDisposition, and Java type class com.sun.jersey.core.header.FormDataContentDisposition, and MIME media type multipart/form-data was not found.
The registered message body readers compatible with the MIME media type are:

问候。
显然在pom.xml中有一个依赖关系问题,并且配置错误,如果可以帮忙,我会把它留给其他人:
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces({ MediaType.APPLICATION_JSON })
public ServiceResponse uploadFIle(FormDataMultiPart form) {
byte[] fileContents = form.getField("iconBmp").getValueAs(byte[].class);
String uploadedfilename = form.getField("iconBmp").getContentDisposition().getFileName();
String description = form.getField("description").getValue();
String fileName = form.getField("fileName").getValue();
//String id = form.getField("id").getValue();
// TODO:
//catIconBean.uploadIcon(fileContents);
ServiceResponse sr = new ServiceResponse();
sr.httpResponse = true;
return sr;
}
问候。
