使用注释进行映射时的 Hibernate QuerySyntaxException
Hibernate QuerySyntaxException when using annotations for mapping
我有一个名为 USER 的数据库 table 和一个名为 User 的模型 class，使用 javax.persistence 注释为 @Entity。当我尝试查询用户时，出现以下异常：
SEVERE: Servlet.service() for servlet [Jersey Web Application] in context with path [/myapp] threw exception [java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: User is not mapped [FROM User u WHERE u.username = :username]] with root cause

我的查询在名为 UserService.java 的服务 class 中进行，如下所示：
import javax.persistence.TypedQuery;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import com.xxxxxx.model.User;
public class UserService {
private static SessionFactory factory;
public UserService() {
}
public User getUser(String username) {
try{
factory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Failed to create sessionFactory object." + ex);
throw new ExceptionInInitializerError(ex);
}
Session session = factory.openSession();
Transaction tx = null;
User user = null;
try {
tx = session.beginTransaction();
TypedQuery<User> query = session.createQuery("FROM User u WHERE u.username = :username", User.class).setParameter("username", username);
user = query.getSingleResult();
} catch(HibernateException e) {
if (tx != null) {
tx.rollback();
}
e.printStackTrace();
} finally {
session.close();
}
return user;
}
}
我的模型class如下：
import javax.persistence.*;
@Entity
@Table(name="USER")
public class User {
@Id @GeneratedValue
@Column(name="id")
private long id;
@Column(name="username", unique=true)
private String username;
@Column(name="email")
private String email;
@Column(name="created")
private Timestamp created;
public User(long id, String username, String email) {
this.id = id;
this.username = username;
this.email = email;
}
}
对于大多数遇到同样问题的人来说，他们似乎使用的是 table 名称而不是实体名称。但是，就我而言，我认为我使用的是正确的实体名称。我还尝试删除 User 的构造函数的参数和正文，但没有帮助。
为清楚起见，下面是我的 hibernate.cfg.xml:
<hibernate-configuration>
<session-factory>
<!-- connection settings -->
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/myapp</property>

<property name="hibernate.connection.password">xxxxx</property>

<!-- mapping files -->
<!-- dev config - remove at prod -->
<property name="hibernate.hbm2ddl.auto">update</property>

由于某种原因，注释未被处理。您要么需要创建一个映射文件并将其包含在您的配置中，https://www.tutorialspoint.com/hibernate/hibernate_mapping_files.htm or as long as I remember there is a way to specify annotation configuration during hibernate session creation where you specify annotated entities. You are probably missing that part. Please, check this for reference Add Annotated Class in Hibernate by adding all classes in some package. JAVA
