@CrossOrigin(origins = "*", maxAge = 3600)
@RequestMapping(value = "/api/v1/staffs", produces = { "application/json" }, method = RequestMethod.GET)
RestResponseList<"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<"text-align: center">

5.查看响应码415，错误原因：
"status": 415,

"error": "Unsupported Media Type",

"exception": "org.springframework.web.HttpMediaTypeNotSupportedException",

"message": "Content type 'text/plain;charset=UTF-8' not supported"


6.进一步查看请求头信息，content-type为text/plain。与Response Headers的Content-Type:application/json;charset=UTF-8类型不匹配，故报错。

7.指定请求头content-type为application/json，比如在Angular中增加Headers。发送Post请求，请求成功。


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;
})




另：也可以在HttpServletResponse对象通过setHeader("Access-Control-Allow-Origin", "*")方法增加响应头参数，解决跨域问题，即是@CrossOrigin注解方式。推荐使用注解，方便。
