Question

<script>
    angular.module("suiteESCWeb", ["ngMessages"]);
    angular.module("suiteESCWeb").controller("usuarioCtrl", function ($scope, $http) {
        $scope.app = "Lista Telefonica";

        $scope.usuario = [];

           var config = {headers: {
                'Content-Type': 'application/json',
                'Access-Control-Allow-Origin' : '*',
                'Access-Control-Allow-Methods' : 'GET, POST, PUT, DELETE',
                'X-Requested-With': 'XMLHttpRequest',
                'Access-Control-Allow-Headers' : 'Origin, X-Requested-With, Content-Type, Accept'
            }
        };

        var carregarUsuario = function () {
            $http.get("http://localhost:8080/usuario/1", config).success(function (data) {

                console.log(data);
                $scope.usuario = data;
            }).error(function (data, status) {
                $scope.message = "Aconteceu um problema: " + data;
            });
        };

        carregarUsuario();
    });

我开始研究AngularJS，Back-End的一部分正在完美地完成由邮递员在chrome上测试的URL现在尝试集成，尝试进行这个简单的调用并且似乎永远不会传递标题。

我一直有的错误是：

{"timestamp":1473905412331,"status":415,"error":"Unsupported Media Type","exception":"org.springframework.web.HttpMediaTypeNotSupportedException","message":"Content type 'null' not supported","path":"/usuario/1"}

public class CORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, Content-Type");
        response.setContentType("text/html; charset=UTF-8");
        response.setCharacterEncoding("UTF-8");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}
}

试试这个，

        $http({
            method: "GET", 
            url: 'http://localhost:8080/usuario/1',
            headers: config
        }).
        success(function (data, status, headers, config) {          
        }).
        error(function (data, status, headers, config) {                
        });

我无法通过标题
