Question

我的Spring Boot应用程序中有两个实体：

用户：

public class User implements java.io.Serializable, UserDetails  {
@GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "person") )
@Id
@GeneratedValue(generator = "generator")

@Column(name = "person_id", unique = true, nullable = false)
public int getPersonId() {
    return this.personId;
}

public void setPersonId(int personId) {
    this.personId = personId;
}

@OneToOne(fetch = FetchType.LAZY)
@PrimaryKeyJoinColumn
public Person getPerson() {
    return this.person;
}

public void setPerson(Person person) {
    this.person = person;
}

    @Column(name = "email", unique = true, nullable = false, length = 50)
public String getEmail() {
    return this.email;
}

public void setLoginVersuche(int loginVersuche) {
    this.loginVersuche = loginVersuche;
}

@Column(name ="loginVersuche")
public int getLoginVersuche() {
    return loginVersuche;
}
...omitted code...

}

和人：

public class Person implements java.io.Serializable {

@Id
@GeneratedValue(strategy = IDENTITY)

@Column(name = "idPerson", unique = true, nullable = false)
public Integer getIdPerson() {
    return this.idPerson;
}

public void setIdPerson(Integer idPerson) {
    this.idPerson = idPerson;
}

@OneToOne(fetch = FetchType.LAZY, mappedBy = "person")
public User getUser() {
    return this.user;
}

public void setUser(User user) {
    this.user = user;
}
...omitted code...
}

我有我的DAO：

@Repository
public interface UserDAO extends CrudRepository<User, Integer>{
    User findByEmail(String user);
}

现在我想更新身份验证中的字段。为此，我要求User对象（电子邮件是唯一的）并设置字段。在此之后我想更新db：

中的对象

User userByDB = userDAO.findByEmail(username);    
userByDB.setLoginVersuche(userByDB.getLoginVersuche()+1);
userDAO.save(userByDB);

它只是不更新db中的数据字段，但我也没有收到任何错误。是否与用户外键中的主键有关？

UPDATE-1

@Transactional
    @Modifying
    @Query("update User u set u.loginVersuche = u.loginVersuche+1, u.gesperrt = ?1 where u.email = ?2")
    public int incrementLoginVersuche(boolean gesperrt, String email);

TransactionManager配置：

@Bean(name = "transactionManager")
    public PlatformTransactionManager txManager() {
        return new DataSourceTransactionManager(dataSource());
    }

Answer 1

根据docs (4.6. Transactionality)

默认情况下，存储库实例上的CRUD方法是事务性的

因此您不需要在@Transactional(readOnly = true)界面上方添加UserDAO注释。相反，您应该使您的保存方法具有事务性（假设您的类是有效的Spring组件）：

@Transactional
public void incrementVersuche() {
    ...    
    User userByDB = userDAO.findByEmail(username);    
    userByDB.setLoginVersuche(userByDB.getLoginVersuche()+1);
    userDAO.save(userByDB);
}

<强>更新

public interface IUserSaver { 
        void incrementVersucheAndSave(String username)
}

@Service
public class UserSaver implements IUserSaver {

@Transactional
public void incrementVersucheAndSave(String username) {
        User userByDB = userDAO.findByEmail(username);    
        userByDB.setLoginVersuche(userByDB.getLoginVersuche()+1);
        userDAO.save(userByDB);
      }
}

然后在你的AuthProvider中：

....
@Autowired
private IUserSaver saver;

 public void incrementLoginVersuche() {
   ....
   saver.incrementVersucheAndSave(username);
}

Answer 2

删除

@Transactional（readOnly = true）

来自您的存储库的

。该事务不会抛出异常： @Transactional readOnly

Answer 3

没有事务调用的方法。检查你的tr demercations或来电环境。不是事务性的。原始问题：如果设置tr RO，它将不会执行更新SQL命令。

使用Spring Repo更新OneToOne的列
