很气愤的一件事，我刚刚写好的一篇博客，点击提交时，博客园的程序报错！白写了！现在大家看到这篇是减缩版，代码是可以使用的，只是有些解释型语言，我不想在重复一遍了，希望博客园的管理者好好管理，不要再出现类似问题了。
使用jersey发布上传图片服务需要依赖两个jar包：jersey-multiart.jar，mimepull.jar
前端html：
<form id="messageform" class="messagetable" enctype="multipart/form-data" method="post" >
<div class="messagebody">
<textarea name="message" rows="5" cols="5" data-dojo-attach-point="messageNode"></textarea>
<input type="hidden" name="ids" id="checkedids">
<input type="hidden" name="terminalid" id="terminalid">
</div>
<input name="file" type="file" accept="image/*" single name="file" data-dojo-attach-point="fileNode" data-dojo-attach-event="onchange: onFileLoad">
<img data-dojo-attach-point="imgNode" src="" >
<input type="submit" value="上传图片" data-dojo-attach-event="onclick:onUploadImg">
<input type="button" value="发送" data-dojo-attach-event="onclick:onSendMessage">
</form>javascript：
uploadImg: function(form){
var myhostname = "http://" + window.location.hostname + ":"
+ window.location.port;
var url = myhostname + "/TrackingSys/services/ConductControl/uploadImg";
form.ids = this.getStrIds();
console.log(form);
iframe(url, {
form: form,
//url: url,
method: 'POST',
handleAs: "html"
}).then(lang.hitch(this, 'uploadSuccess'), lang.hitch(this, 'err'));
},
uploadSuccess: function(res){
var contentNode = res.childNodes[0];
if (contentNode){
var content = contentNode.textContent? contentNode.textContent : contentNode.innerText;
var data = JSON.parse(content);
console.log(data);
}
},后台：注意返回的格式
@POST @Path("/uploadImg")
@Consumes(MediaType.MULTIPART_FORM_DATA) // 消费注解必须是这个类型
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public String uploadImg(@FormDataParam("file") InputStream uploadedStream,
@FormDataParam("ids") String ids, @FormDataParam("terminalid") String terminalid){
String[] checkIds = ids.split(",");
String result = dao.sendImgToTerminal(terminalid, uploadedStream, checkIds);
String re = "<html>{\"result\":\"" + result + "\"}</html>";
return re;
}插入图片部分：不能使用被注释掉的那种写法
rpt = conn.prepareStatement(sql);
BufferedInputStream bs = new BufferedInputStream(picData);
ByteArrayOutputStream outputStream=new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int len=picData.read(bytes);
while (len != -1) {
outputStream.write(bytes, 0, len);
len=picData.read(bytes);
}
rpt.setBytes(1, outputStream.toByteArray());
//rpt.setBinaryStream(1, picData,picData.available() );
rpt.setInt(2, imageId);
rpt.executeUpdate();
