java - 使用 angularjs 和 spring boot 将数据存储到数据库中的问题

Question

这就是我所拥有的:

用户.java

@Entity
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;

    @Column
    private String username;

    @Column
    private String password;

    @Column
    private String lastname;

    public Integer getId() {
        return id;
    }

    public String getLastname() {
        return lastname;
    }

    public String getPassword() {
        return password;
    }

    public String getUsername() {
        return username;
    }
}

UserController.java

@RestController
@RequestMapping("/user")
public class UserController {
    @Autowired
    private UserRepository repo;

    @RequestMapping(method = RequestMethod.POST)
    public User addUser(@RequestBody User user) {
        return repo.saveAndFlush(user);
    }

用户.service.js

注意:这里控制台输出了用户名、密码和姓氏这3个值。

    function Create(user) {

        console.log(user.username)
        console.log(user.password)
        console.log(user.lastName)


        return $http.post('/user', user).then(handleSuccess, handleError('Error creating user'));
    }

注册.controller

(function () {
    'use strict';

    angular
        .module('app')
        .controller('RegisterController', RegisterController);

    RegisterController.$inject = ['UserService', '$location', '$rootScope', 'FlashService'];
    function RegisterController(UserService, $location, $rootScope, FlashService) {
        var vm = this;

        vm.register = register;

        function register() {
            vm.dataLoading = true;
            UserService.Create(vm.user)
                .then(function (response) {
                    if (response.success) {
                        FlashService.Success('Registration successful', true);
                        $location.path('/login');

                    } else {
                        FlashService.Error(response.message);
                        vm.dataLoading = false;
                    }
                });
        }
    }

})();

注册.html

<div class="container" ng-controller="RegisterController as vm">
<div class="col-md-6 col-md-offset-3">
    <h2>Register</h2>
    <div ng-show="vm.error" class="alert alert-danger">{{vm.error}}</div>

        <div class="form-actions">

</div>

但由于某种原因，这是用户的结果。

{id: 1, username: "33", password: "33", lastname: null}
id: 1
lastname: null
password: "33"
username: "33"

无论我做什么，它总是显示为空。我真的不知道我错过了什么

有人知道这件事吗？我想我一直在忽略一些事情。

Answer 1

您的 View 和服务将姓氏的数据指定为lastName，您的模型为小写。
