带有spring restcontroller的跨域ajax请求问题

我正面临着使用ajax进行跨域请求的问题。

以下是我的春季控制器的代码：

@RestController @RequestMapping(value = "/help") public class MYController { @Autowired private MyService myService; private static final int SUCCESS = 1; private static final int FAIL = 0; @RequestMapping(value = "save", method = RequestMethod.POST,produces={"application/json"}) public int save(@RequestBody Item item,HttpServletRequest request,HttpServletResponse response) { response.addHeader("Access-Control-Allow-Origin","*"); response.addHeader("Access-Control-Allow-Methods","GET, PUT, POST, DELETE, OPTIONS"); response.addHeader("Access-Control-Allow-Headers","Content-Type, Content-Range, Content-Disposition, Content-Description"); try { myService.save(item); return SUCCESS; } catch (Exception ex) { ex.printStackTrace(); return FAIL; } } } 

上面的代码是我的rest服务的一部分，它在其他tomcat上运行。

以下是我的脚本代码，这是我的客户端代码。

 $.ajax({ type: "POST", url:"http://10.10.13.215:9092/helpProject/help/save", crossDomain: true, dataType: "JSON", data:JSON.stringify(item), //item is my pojo here headers : {Accept : "applicationjson","Access-Control-Allow-Origin" : "*"}, success: function(msg) { alert(msg); }, error: function (e) { alert("errorrrrrr"); } }); 

我在浏览器的控制台中收到以下错误：

 XMLHttpRequest cannot load http://10.10.13.215:9092/helpProject/help/save", No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8082' is therefore not allowed access. 

请帮忙解决..谢谢

尝试添加此filter。

 @Component public class CorsFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { // TODO Auto-generated method stub } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletResponse res = (HttpServletResponse) response; res.setHeader("Access-Control-Allow-Origin", "*"); res.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE"); res.setHeader("Access-Control-Max-Age", "3600"); res.setHeader("Access-Control-Allow-Headers", "x-requested-with"); chain.doFilter(request, res); } @Override public void destroy() { // TODO Auto-generated method stub } }
