Angular客户端请求Rest服务跨域问题的解决方法

@CrossOrigin(origins = "", maxAge = 3600)
@RequestMapping(value = "/api/v1/staffs", produces = { "application/json" }, method = RequestMethod.GET)
RestResponseList<?> queryStaffs(@RequestParam(value = "limit", required = false, defaultValue = "20") int limit,
 @RequestParam(value = "offset", required = false, defaultValue = "0") int offset);

@CrossOrigin(origins = "", maxAge = 3600)
@RequestMapping(value = "/api/v1/staffs", produces = { "application/json" }, method = RequestMethod.POST)
RestResponse<?> createStaff(@RequestBody RestRequest<StaffReqInfo> request);

let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers });

return this.http.post(this.staffCreateURL, body, options).map((response: Response) => {
 //return this.http.get(this.userLoginURL).map((response:Response)=> {
 let responseInfo = response.json();
 console.log("====请求staffCreateURL成功并返回数据start===");
 console.log(responseInfo);
 console.log("====请求staffCreateURL成功并返回数据end===");
 let staffName = responseInfo.responseInfo.staffName;
 console.log(staffName);
 return responseInfo;
})
