前台报错 415 (Unsupported Media Type)

Question

//异步上传图片 function doploy(){ //定义参数 var options={ url:"rest/process/deploy/", dataType:"text", type:"post", success:function(data){ alert(data); }, error:function(){ alert("upload error"); } }; //使用jquery.form异步上传图片 $("#deployProcess").ajaxSubmit(options); }

请选择发布的流程：
onclick="doploy()" />

@POST
@Path("/deploy/")
@Produces(MediaType.APPLICATION_JSON)
@LogAnnotation(operationName = "发布流程")
public String deployProcess(@RequestParam(required=false) MultipartFile processDef) {

ZipInputStream zis = null;
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
.getRequestAttributes()).getRequest();
try {
request.setCharacterEncoding("UTF-8");
String deployFile = request.getParameter("processDef");
if (deployFile != null && !deployFile.isEmpty()) {
ProcessEngine processEngine = Configuration.getProcessEngine();
RepositoryService repositoryService = processEngine
.getRepositoryService();

            zis = new ZipInputStream(processDef.getInputStream());
            repositoryService.createDeployment()
                    .addResourcesFromZipInputStream(zis).deploy();
            zis.close();
        } else {
            return GlobalConstant.FAILURE;
        }
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return GlobalConstant.FAILURE;
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return GlobalConstant.FAILURE;
    } finally {
        try {
            if(zis != null){
                zis.close();
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }
    return GlobalConstant.SUCCESS;
}

Answer 1

var options = {

target: '#output', //把服务器返回的内容放入id为output的元素中

beforeSubmit: showRequest, //提交前的回调函数

success: showResponse, //提交后的回调函数

url: url, //默认是form的action， 如果申明，则会覆盖

type: type, //默认是form的method（get or post），如果申明，则会覆盖

dataType: null, //html(默认), xml, script, json...接受服务端返回的类型

clearForm: true, //成功提交后，清除所有表单元素的值

resetForm: true, //成功提交后，重置所有表单元素的值

timeout: 3000 //限制请求的时间，当请求大于3秒后，跳出请求

}

你的程序报的是：不支持的媒体类型，所以定位到dataType字段的属性，你把它换成上面的格式试一下，看看哪一种可以通过
