我的环境是Spring 4.0.5，hibernate 4.3.6，hsql 2.3.2。在生产中它将连接到mysql。 我在执行本机查询时不断找到列。
这是我的实体
@Entity
@Table(name = "taxonomy")
public class Taxonomy implements AwrDO, Searchable {
@Id
@Column(name = "taxonomy_sid", nullable = false)
private Long sid;
@Column(name = "taxonomy_id", nullable = false)
private Long taxonomyId;
@Column(name = "region_id", nullable = false)
private Integer regionId;
@Column(name = "taxonomy_name")
private String taxonomyName;
// weird column
@Column(name = "event_type_id")
private Integer evnetTypeId;
}
我的命名本机查询和SqlResultSetMapping是
@NamedNativeQuery(
name = "getNextLevelFromIdAndRegion",
query = "select t.taxonomy_sid, t.taxonomy_id, t.region_id, t.taxonomy_name " +
"from ... ",
resultSetMapping = "getNextLevelFromIdAndRegion"
)
@SqlResultSetMapping(name = "getNextLevelFromIdAndRegion", entities = { @EntityResult(entityClass = Taxonomy.class, fields = {
@FieldResult(name = "sid", column = "taxonomy_sid"),
@FieldResult(name = "taxonomyId", column = "taxonomy_id"),
@FieldResult(name = "regionId", column = "region_id"),
@FieldResult(name = "taxonomyName", column = "taxonomy_name")
)
因此，在我的原生查询中，我只对前四列感兴趣，而我只选择那些并且仅在结果集映射中指定它们。
但是，如果我这样做，我会得到异常抱怨Caused by: java.sql.SQLException: Column 'event_ty4_8_0_' not found.，甚至认为本机查询在mysql中有效。
解决方法是选择@Entity中定义的所有列，并将所有列放在SqlResultSetMapping中。关于如何定义我的实体有什么不对吗？

来自@EntityResult的 Javadoc ：
用于将SQL查询的SELECT子句映射到实体结果。 如果使用此批注，则应选择SQL语句 所有映射到实体对象的列。 这应该包括相关实体的外键列。 当数据不足时获得的结果 未定义。
