JHipster 4.14.1:向用户注册其他信息
首先,我要感谢" Paul Etienne "提出的有用的问题和答案!下面的答案稍微详细一点,并考虑到最后一个版本的JHipster(3/17/2018).
问题很明确:如何在JHipster项目中向User实体添加新数据字段.

正如官方JHipster网站中所提到的,向默认JHipster用户添加新字段/关系的最佳方式是创建一个新实体,并将其与一对一关系链接到用户.您可以在新实体中处理更多关系.我们称之为新的Entity UserExtra.
上面的UML图显示了User和UserExtra之间的组合,这意味着User具有强烈依赖于User的UserExtra,并且在没有User的情况下不能存在.换句话说,应该有一个用户,所以我们可以分配一个电话号码.
第1步:创建一个新实体
我建议使用终端创建新实体:jhipster entity userExtra
要么
JDL:
第2步:修改新实体
您可以在域文件夹下找到新的实体类:
我们可以将UserExtra的id映射到User的id,这样我们就可以使用UserExtra的id作为外键.如果是这样,那么我们就不应该在UserExtra中对id使用@GeneratedValue注释了.这是一个示例UserExtra类.以下是修改后的UserExtra示例:
package org.jhipster.domain;
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Objects;
/**
* A UserExtra.
*/
@Entity
@Table(name = "user_extra")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class UserExtra implements Serializable {
private static final long serialVersionUID = 1L;
@Id
private Long id;
@OneToOne
@MapsId
private User user;
@Column(name = "phone")
private String phone;
// jhipster-needle-entity-add-field - JHipster will add fields here, do not remove
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getPhone() {
return phone;
}
public UserExtra phone(String phone) {
this.phone = phone;
return this;
}
public void setPhone(String phone) {
this.phone = phone;
}
public User getUser() {
return user;
}
public UserExtra user(User user) {
this.user = user;
return this;
}
public void setUser(User user) {
this.user = user;
}
// jhipster-needle-entity-add-getters-setters - JHipster will add getters and setters here, do not remove
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (o == null || getClass() != o.getClass()) {
return false;
}
UserExtra userExtra = (UserExtra) o;
if (userExtra.getId() == null || getId() == null) {
return false;
}
return Objects.equals(getId(), userExtra.getId());
}
@Override
public int hashCode() {
return Objects.hashCode(getId());
}
@Override
public String toString() {
return "UserExtra{" +
"id=" + getId() +
", phone='" + getPhone() + "'" +
"}";
}
}
第3步:修改新实体的配置
[如果您在第一步中使用了JDL,则可以跳过此步骤]
有一个json文件保存实体的配置:
我们需要修改配置.这是一个修改过的配置json文件的示例:
{
"fluentMethods": true,
"relationships": [
{
"relationshipType": "one-to-one",
"relationshipName": "user",
"otherEntityName": "user",
"otherEntityField": "id",
"ownerSide": true,
"otherEntityRelationshipName": "userExtra"
}
],
"fields": [
{
"fieldName": "phone",
"fieldType": "String"
}
],
"changelogDate": "20180317190851",
"dto": "no",
"service": "no",
"entityTableName": "user_extra",
"jpaMetamodelFiltering": false,
"pagination": "no"
}
还有一些xml更改日志:
以下是样本更改日志:

baseTableName="user_extra"
constraintName="fk_user_extra_user_id"
referencedColumnNames="id"
referencedTableName="jhi_user"/>
</changeSet>
</databaseChangeLog>
请注意,JHipster为User实体使用名为"JHI_USER"的表,并为新实体创建了一个名为"USER_EXTRA"的表.我们将命名新实体"USER_ID"的primary-key/id字段:
第4步:修改ManagedUserVM.java
ManagedUserVM类是一种扩展UserDTO的DTO,它在REST控制器中使用.
此修改的目的是添加我们将要绑定到User的新字段作为额外信息.以下是此类的示例代码.phone属性已添加到修改后的类中:
package org.jhipster.web.rest.vm;
import org.jhipster.service.dto.UserDTO;
import javax.validation.constraints.Size;
/**
* View Model extending the UserDTO, which is meant to be used in the user management UI.
*/
public class ManagedUserVM extends UserDTO {
public static final int PASSWORD_MIN_LENGTH = 4;
public static final int PASSWORD_MAX_LENGTH = 100;
@Size(min = PASSWORD_MIN_LENGTH, max = PASSWORD_MAX_LENGTH)
private String password;
private String phone;
public ManagedUserVM() {
// Empty constructor needed for Jackson.
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
@Override
public String toString() {
return "ManagedUserVM{" +
"} " + super.toString();
}
}
第5步:修改UserService.java
在这个calss中有一个名为"registerUser"的方法,它负责注册一个新用户:
修改此服务类的目的是强制它在添加用户时添加UserExtra对象.这是修改后的"registeruser"方法的示例.您可以在其顶部找到添加的代码"创建并保存UserExtra实体"作为注释:
public User registerUser(UserDTO userDTO, String password, String phone) {
User newUser = new User();
Authority authority = authorityRepository.findOne(AuthoritiesConstants.USER);
Set<Authority> authorities = new HashSet<>();
String encryptedPassword = passwordEncoder.encode(password);
newUser.setLogin(userDTO.getLogin());
// new user gets initially a generated password
newUser.setPassword(encryptedPassword);
newUser.setFirstName(userDTO.getFirstName());
newUser.setLastName(userDTO.getLastName());
newUser.setEmail(userDTO.getEmail());
newUser.setImageUrl(userDTO.getImageUrl());
newUser.setLangKey(userDTO.getLangKey());
// new user is not active
newUser.setActivated(false);
// new user gets registration key
newUser.setActivationKey(RandomUtil.generateActivationKey());
authorities.add(authority);
newUser.setAuthorities(authorities);
userRepository.save(newUser);
cacheManager.getCache(UserRepository.USERS_BY_LOGIN_CACHE).evict(newUser.getLogin());
cacheManager.getCache(UserRepository.USERS_BY_EMAIL_CACHE).evict(newUser.getEmail());
log.debug("Created Information for User: {}", newUser);
// Create and save the UserExtra entity
UserExtra newUserExtra = new UserExtra();
newUserExtra.setUser(newUser);
newUserExtra.setPhone(phone);
userExtraRepository.save(newUserExtra);
log.debug("Created Information for UserExtra: {}", newUserExtra);
return newUser;
}
第6步:修改AccountResource.java
此类是一个REST控制器,负责与帐户相关的活动:
在这个控制器中有一个名为"registerAccount"的方法,它调用UserService类的"registerUser"方法:
User user = userService.registerUser(managedUserVM, managedUserVM.getPassword());
我们需要修改这一行,以便我们可以将新字段传递给方法:
@PostMapping("/register")
@Timed
@ResponseStatus(HttpStatus.CREATED)
public void registerAccount(@Valid @RequestBody ManagedUserVM managedUserVM) {
if (!checkPasswordLength(managedUserVM.getPassword())) {
throw new InvalidPasswordException();
}
userRepository.findOneByLogin(managedUserVM.getLogin().toLowerCase()).ifPresent(u -> {throw new LoginAlreadyUsedException();});
userRepository.findOneByEmailIgnoreCase(managedUserVM.getEmail()).ifPresent(u -> {throw new EmailAlreadyUsedException();});
User user = userService.registerUser(managedUserVM, managedUserVM.getPassword(), managedUserVM.getPhone());
mailService.sendActivationEmail(user);
}
第7步:修改用户界面
最后,您需要在html文件中添加一个输入元素:
<div class="form-group">
<label class="form-control-label" for="phone" data-translate="global.form.phone">Phone number</label>
<input type="tel" class="form-control" id="phone" name="phone" #phone="ngModel" placeholder="{{'global.form.phone.placeholder' | translate}}"
[(ngModel)]="registerAccount.phone">
</div>
然后,这是您在注册页面中拥有的内容:
这是数据层:
JHI_USER
USER_EXTRA
PS
最简单的方法是通过JDL添加一个与User一对一关系的UserExtra实体,并在创建新用户时添加"userExtra".
