        httpResponse.setHeader("Access-Control-Allow-Origin",

        // 表明它允许xxx的外域请求

        chain.doFilter(request, response);
    }

}
但是请求的时候还是会报 已拦截跨源请求:同源策略禁止读取位于 http://127.0.0.1:8080/NutzWk-bootstrap-3.3.x/platform/cms/article/sendPropertyMessages 的远程资源。(原因:CORS 头 'Access-Control-Allow-Origin' 不匹配 '*, *')

用域名测试

@wendal
$.ajax({
url: "http://127.0.0.1:8080/NutzWk-bootstrap-3.3.x/platform/cms/article/sendPropertyMessages",
contentType: "application/json;charset=utf-8",
type: "POST",
data: JSON.stringify({

                 "cms_article": {
                   "title": "test"
                 },

              }),
         dataType: "json",
         cache: false,
         success: function(message) {

         }
       });

httpResponse.setHeader("Access-Control-Allow-Origin","http://127.0.0.1:8080"); 这样吗
还是报
已拦截跨源请求:同源策略禁止读取位于 http://127.0.0.1:8080/NutzWk-bootstrap-3.3.x/platform/cms/article/sendPropertyMessages 的远程资源。(原因:CORS 头 'Access-Control-Allow-Origin' 不匹配 'http://127.0.0.1:8080, *')。

nutz有CrossOriginFilter

我说的是, 不要用127.0.0.1这样的地址测试
