Spring Boot 2.0.0.RELEASE迁移后出现“获取不同大小的元组和别名”异常
Spring Boot 2.0.0.RELEASE迁移后出现“获取不同大小的元组和别名”异常

//imports, etc.
@Entity
@Table(name = "TSTRANS")
@SqlResultSetMappings(
{
@SqlResultSetMapping(name = TS_TRANS_EMP_STAT,
classes = {
@ConstructorResult(
targetClass = EmpStat.class,
columns = {
@ColumnResult(name = "EMPID", type = Long.class),
@ColumnResult(name = "CODE", type = String.class),
@ColumnResult(name = "TOTALCOUNT", type = Integer.class)
}
)
})
}
)
@NamedNativeQueries({
@NamedNativeQuery(name = "TsTrans.getStat", query = "select * from SP_TASK_STATS_EMP (:in_empid, :in_gidstr, :in_onlytodo)", resultSetMapping = TS_TRANS_EMP_STAT)
})
public class TsTrans extends TsTransCommon {
public static final String TSTRANS_BADGE = "TSTRANS_BADGE";
private static final long serialVersionUID = -3391028108003625153L;
public static final String TS_TRANS_EMP_STAT = "TsTrans.empStat";
public static final String TS_TRANS_SCHEDULE_STAT = "TsTrans.getScheduleStat";
public static final String TS_TRANS_FOLLOWUP = "TS_TRANS_FOLLOWUP";
}这就是实体。
// imports, etc.
public class EmpStat extends BaseStat {
private static final long serialVersionUID = -4410895509438727581L;
private Long mEmpid;
public EmpStat(Long aEmpid, String aCode, Integer aTotalcount) {
super(aCode, aTotalcount);
mEmpid = aEmpid;
}
public Long getEmpid() {
return mEmpid;
}
public void setEmpid(Long aEmpid) {
mEmpid = aEmpid;
}
}这是非实体pojo，namedquery返回类型。
// imports, etc.
@Repository
public interface TsTransRepository extends TsTransCommonRepository<TsTrans> {
List<EmpStat> getStat(@Param("in_empid") Long aEmpid, @Param("in_gidstr") String aGidstr, @Param("in_onlytodo") Boolean aOnlytodo);
}这是存储库类。
我使用这个namednativequeries从存储过程返回非实体pojos。从Spring Boot 1.5.9开始，它就一直在工作，没有例外。在Spring Boot 2.0.0.M7上。迁移到2.0.0.RELEASE后，开始出现以下异常。

在JPA2.1中，将@Query(nativeQuery = true)注释放在存储库接口方法上，修复了这个问题。参考资料：

将您的SqlResultSetMappings更改为
@SqlResultSetMappings({
@SqlResultSetMapping(name = TS_TRANS_EMP_STAT,
columns = {
@ColumnResult(name = "EMPID", type = Long.class),
@ColumnResult(name = "CODE", type = String.class),
@ColumnResult(name = "TOTALCOUNT", type = Integer.class)
})
}并将EmpStat从普通类更改为接口：
public interface EmpStat {
Long getEMPID();
String getCODE();
Integer getTOTALCOUNT();
