如何创建具有多个端点连接到的单个端点

Question

我正在尝试创建下表以在用户注册时获取用户信息。

根据我在互联网上阅读的教程，我需要创建四个实体类，分别是USER，USER_DETAILS，ROLE和USER_ROLE。 但是我的问题是，当我想在应用程序中创建用户时，我是否必须具有4种不同的发布方法，或者有一种方法可以一次将用户数据添加到相关表中。

我希望能够将数据发布到单个url，并在用户提供所有详细信息时立即填充所有带有外键的表。

就像是 ：

{
    "userName": “ME",
    "password": "1234”,
    “DOB": “1988-05-12",
    "email": “test@test.org",
    “role": “admin",
    "country": "Ireland",
    "registrationLocation": "Dublin",
    "timeStamp": "18-01-2018T12:23:08"
}

将其发布到单个网址，例如：localhost：8080 / live / api

这是我的代码：

用户详细信息

public class UserDetails {
    @Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

private Users user;


@NotBlank
private String DOB;

public UserDetails() {
}

public UserDetails( String DOB) {
    this. DOB = DOB;
}

public String getDOB() {
    return DOB;
}

public void setTitle(String DOB) {
    DOB = DOB;
}


 @OneToOne(cascade = CascadeType.ALL)


 @JoinColumn(name = "userID")
    public Users getUser() {
        return user;
    }

用户

@Entity
@Table(name = "Users", 
uniqueConstraints = 
          {
                @UniqueConstraint(columnNames = "email"),
                @UniqueConstraint(columnNames = "username")
        }

)

public class Users implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long userID;

@NotBlank
@Size(min = 5, max = 100, message = "Please enter between 8 and 100 characters.")
private String password;

@NotBlank
private String username;

private Role role;

public Users() {

}

public Users(long userID, String password, String username, Role role) {
    this.userID = userID;
    this.password = password;
    this.username = username;
    this.role = role;
}


@OneToMany(cascade = CascadeType.ALL)
@JoinColumn(name = "roleID")
public Role getRoles() {
    return role;
}

public long getUserID() {
    return userID;
}

public void setUserID(long userID) {
    this.userID = userID;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public Role getRole() {
    return role;
}

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



}

用户角色

@Entity
public class UserRole implements Serializable {


    private Role role;

    private Users user;

    public UserRole() {
    }

    public UserRole(Role role, Users user) {
        this.role = role;
        this.user = user;
    }

    public Role getRole() {
        return role;
    }

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

    public Users getUser() {
        return user;
    }

    public void setUser(Users user) {
        this.user = user;
    }



}

控制器类方法

@RequestMapping(method = RequestMethod.POST, value = "/api/usermanagement/users")
public Response createUser(@Valid @RequestBody Users user){
    return userService.AddUser(user);

 }

您可以像给出示例一样将所有相关信息发布到1个端点，然后从UserService类（最好是Impl类）中，可以调用所有相关方法以保存相关详细信息。 例如，

@Service
public class UserServiceImpl implements UserService {

public Response addUser(Users user){
   //get details from Users and populate to entities User and UserDetails.
   // Save User and UserDetails. Return Response
 }
 }
