Angularjs REST服务中角度JS POST请求映射到DTO

我不熟悉Angular JS和REST服务，只是尝试一下hello world

web.xml

<servlet>
        <servlet-name>jersey-helloworld-serlvet</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
             <param-name>com.sun.jersey.config.property.packages</param-name>
             <param-value>com.ipocc.service</param-value>
        </init-param>
        <init-param>
            <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

DTO

角度JS文件

var validationApp = angular.module('validationApp', []);
validationApp.controller('mainController', function($scope,$http) {
    $scope.submitForm = function() {

            var update_path = "http://localhost:8080/IPOCCService/rest/UserManager/validate";
            var data1 = angular.toJson($scope.user);
            alert(data1);            
            $http({
                  url: update_path, 
                  method: "POST",
                  data:  data1,
                  headers : {
                         "Content-Type" : "application/json; charset=utf-8",
                         "Accept" : "application/json"
                   }
             }).
             success(function(data, status, headers, config) {
                 alert("success");
             }).
             error(function(data, status, headers, config) {
                 alert("failure");
             });

    };
});

我面临的错误

我想实现当我从Angular JS调用http post请求时，它应该得到映射到用户对象，但我得到了上面的错误。如果我将参数保留为字符串，则我将以电子邮件的形式获取数据：a@a.com，name:j，username:j

我不熟悉jersey，但您似乎缺少jersey json依赖项来解析收到的json数据。-

如果它能帮助某人

我很抱歉犯了错误。在我的依赖项中，jar版本不匹配，在pom.xml中做了如下更改后，现在可以工作了

        <dependency>
            <groupId>com.sun.jersey</groupId>
