                @SqlResultSetMapping(name = TS_TRANS_EMP_STAT,
                        classes = {
                                @ConstructorResult(
                                        targetClass = EmpStat.class,

                                                @ColumnResult(name = "CODE", type = String.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。

我正在使用此 namednativequeries 从存储过程返回非实体 pojos 。自从Spring Boot
1.5.9起，它一直毫无例外地工作。在Spring Boot 2.0.0.M7上。迁移到2.0.0.RELEASE之后，开始发生以下异常。

在迁移过程中，我是否错过任何事情？
