Question

我创建了一个控制器来将新用户添加到数据库中但是当我在邮递员中测试Post请求时我得到了这个错误：

{“code”：null，“message”：“缺少必需的请求正文：public com.pack.model.persistent.User com.pack.restapi.controllers.UserController.create（com.model.persistent.User）“}

这是做了什么：

//User class
@Entity
public class User extends PersistenceGenerique {

	private static final long serialVersionUID = 245457152874587458468L;
	
	@Column
	@OrderBy
	private String firstname;

	@Column
	private String lastname;

	@Column
	private String email;

//service
public User create(User user);

//serviceIMPL

@Override
	public User create(User user) {
	userDao.persist(user);
	return user;
		    }
        
//RestController
	 @PostMapping
	    public User create(@RequestBody User user){
	        return userService.create(user);
	    }

的修改

以下是我的打字稿代码以获取更多详细信息：

    createUser(): void {
        this.usrSRV.CreateUser(this.user)
            .subscribe(data => {
                alert("User created successfully.");
            });

    };

   CreateUser(user) {
        const userUrl = this._userUrl;        
        return this.http.post(userUrl, user)
            .map(res => {
                return res.json();
            })
            .catch(this.handleError);
    }

<form (ngSubmit)="createUser()">
    <div class="form-group">
      <label for="firstname">Firstname</label>
      <input type="text" [(ngModel)]="firstname" placeholder="Firstname" name="firstname" class="form-control" id="firstname">
    </div>
    <div class="form-group">
      <label for="lastname">LastName</label>
      <input [(ngModel)]="lastname" placeholder="lastname" name="lastname" class="form-control" id="lastname">
    </div>
    <div class="form-group">
      <label for="email">email</label>
      <input [(ngModel)]="email" placeholder="email" name="email" class="form-control" id="email">
    </div>
    <button class="btn btn-success">Create user</button>
  </form>
</div>

我的PostRequest中缺少必需的请求正文（将用户添加到数据库）
