java - 使用hibernate和java进行Mysql查询时出错

Question

Mysql查询

sql = new StringBuilder("SELECT * FROM table_name WHERE userId = :userId AND deleteFlag = 0 "
                    + "AND YEAR(NOW()) = YEAR(CreatedDate) ");
            sql.append("ORDER BY Id ");

            query = getSession().createSQLQuery(sql.toString());
            query.addEntity(table_name.class);
            query.setParameter("userId", userId);

型号

public class UserProgramRecommendationV2 implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    Integer id;

    @Column(name="UserId")
    private Long userId;
}

检查数据库中所有行是否与模型中定义的行匹配。

Answer 1

问题是

User#4127404

在模型中的某个位置，您有一个类 X，它与具有 id 4127404 的 User 关联。数据库中不存在具有此类 ID 的用户。
