标签： java angularjs spring spring-mvc spring-restcontroller

我有以下html文件

<!DOCTYPE html>
<html>

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js"></script>
    <script>
    angular.module("myapp", [])
    .controller("MyController", ['$scope', '$http', function($scope, $http) {
        console.log("Start");
        $scope.myForm = {};
        $scope.role = [{ roleName :"A"},{roleName : "B"},{ roleName : "C"}];
        $scope.submitForm = function() {
            var dataObj = {
                    "attUid" : $scope.myForm.firstName,
                    "role" : $scope.myForm.selectedRole
            };  
            $http.post('/UPRS/services/poc/add',dataObj).then(function(response) {
                console.log("Success!");
            },
            function(error) {
                console.log("Something went wrong!");
            });
        }
    }]);
  </script>

</head>

<body ng-app="myapp">

  <div ng-controller="MyController">
    <form ng-submit="submitForm()" method="POST">
      ATTID :
      <input type="text" name="firstName" ng-model="myForm.firstName">
      <br/> Role :
      <select ng-model="myForm.selectedRole" ng-options="r.roleName for r in role"></select>
      <br/>
      <input type="submit" id="submit" value="Submit" />
    </form>
    <div>
      {{myForm.firstName}} {{selectedRole.roleName}}
    </div>
  </div>


</body>

</html>

我的Hibernate对象文件是：

@Entity
@Table(name="ATTUIDRoles")
public class Role {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="No")
    Long no;

    @Column(name="ATTUID")
    String attUid;


    @Column(name="Role")
    String role;


    public Long getNo() {
        return no;
    }


    public void setNo(Long no) {
        this.no = no;
    }


    public String getAttUid() {
        return attUid;
    }


    public void setAttUid(String attUid) {
        this.attUid = attUid;
    }


    public String getRole() {
        return role;
    }


    public void setRole(String role) {
        this.role = role;
    }


}

我的服务档案是：

@RestController
@RequestMapping("/poc")
public class POCService {

    @Autowired
    POCRepository pocRepository;

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public void addPOCDetails(@RequestBody Role role){
        System.out.println("HI");
        System.out.println(role.getAttUid());
        System.out.println(role.getRole());
    }
}

错误生成为：

我已经使用了hibernate对象，就像在responsebody中一样。由于它有什么影响，或者其他东西就是这种情况。请接受我的帮助。

2 个答案:

答案 0 :(得分：1)

h1返回对象。

您应该使用$scope.myForm.selectedRole获取roleName值。

答案 1 :(得分：-1)

将implements Serializable添加到您的角色实体定义。
