我有以下的HTML文件Hibernate对象的在AngularJS @RequestBody和Spring
<!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对象的文件是：
@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;
}
}
我的服务文件是：
@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());
}
}
的错误正在产生为：

我有使用hibernate对象作为responsebody.Will有任何影响，由于它或其他情况是这样的。请亲切地帮助我。
我做了研究，发现在html中，dataObj中的$ scope导致了这个错误，因为当我传递了dataObj中的硬编码值时，它接受了相同的结果。 –
您的问题标题错误地提到'ResponseBody'而不是'RequestBody'（序列化和反序列化是相当不同的主题）。 –
要解决您的问题，只需使用'ng-options =“r.roleName作为角色r中的r.roleName。 –
