@NamedQuery和getNamedQuery - 不兼容的类型

时间：2016-06-30 18:28:52

标签： spring hibernate

我遇到了Hibernate @NamedQuery注释的问题。我在DTO类查询中创建并尝试在DAO类中使用它。但是我遇到了不兼容类型的问题（必需的org.hibernate对象，找到了java.lang.Object）。

DTO CLASS 

import org.hibernate.annotations.NamedQueries;
import org.hibernate.annotations.NamedQuery;
import javax.persistence.*;
import javax.persistence.Entity;
import javax.persistence.Table;
import java.util.Collection;

/**
 * Created by xxx on 22.06.2016.
 */

@Entity
@Table
@AttributeOverride(name = "id", column = @Column(name = "userId"))
@NamedQueries({ @NamedQuery(name = "User_findByEmail",
        query = "select username from user u where u.email=:email") })
public class User extends BaseEntity {
    @JoinTable(name = "user_role",
            joinColumns = @JoinColumn(name = "user_id", referencedColumnName = "userId"),
            inverseJoinColumns = @JoinColumn(name = "role_id", referencedColumnName = "roleId"))
    private Collection<Role> roles;
    @Column(name = "username")
    private String username;
    @Column(name = "password")
    private String password;
    @Column(name = "email")
    String email;
    @Column(name = "enabled")
    boolean enabled;
    @Column(name = "tokenExpired")
    boolean tokenExpired;

DAO CLASS 

import com.adapp.dao.abstr.AbstractHibernateDAO;
import com.adapp.dao.interf.IUserDAO;
import com.adapp.dto.User;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;

import org.springframework.stereotype.Repository;


/**
 * Created by Dom on 22.06.2016.
 */
@Repository
public class UserDAO extends AbstractHibernateDAO<User> implements IUserDAO {

    public UserDAO(){
        super();
        setClazz(User.class);
    }

    @Override
    public User findByMail(String email) {

        Session session = getCurrentSession();
        Transaction tx = null;
        tx = session.beginTransaction();
        Query query = session.getNamedQuery("User_findByEmail")
                .setString(":email", email)
                .uniqueResult();

    }
}

寻求帮助。

User user = session.getNamedQuery("User_findByEmail")
                .setString(":email", email)
                .uniqueResult();

uniqueResult方法将返回您的实体类型，而不是查询。
