hibernate - org.hibernate.PropertyNotFoundException : Could not find setter for flat_rate on class dk. comtalk.billing.server.rating.db.RateDTO 问题

Question

在将 SQL 结果转换为 HQL 时出现此异常。 query.setResultTransformer(Transformers.aliasToBean(RateDTO.class)).list()

但我已经为 RateDTO 类中的 flat_rate 列设置了 setter 和 getter

private BigDecimal flatRate;

    @Column(name="flat_rate")
public BigDecimal getFlatRate() {
    return flatRate;
}   

public void setFlatRate(BigDecimal flatRate) {
    this.flatRate = flatRate;
}

Mysql DB 中对应的表。谁能帮帮我。

Answer 1

尝试使用addScalar()在调用 query.list()

之前查询对象

final String sql = "select * " + "from international_rate r " + "WHERE LEFT(:called, LENGTH(r.prefix)) = r.prefix " + "and r.valid_from <= :date AND ( r.Valid_to >= :date or r.Valid_to = 0)" + "and r.deleted = 0"; "

    sess.createSQLQuery(sql)
     .addScalar("flatRate", Hibernate.STRING) //like all properties need to Add
.setResultTransformer(Transformers.aliasToBean(RateDTO.class)).list();
