[英]Spring JPA Stored Procedure with a null value?
我有一個存儲過程,它是從 JpaRepository 實現中調用的
@Repository
public interface DataMartRepo extends JpaRepository<DataMartDAO, String> {
@Procedure(procedureName = "dbo.txn_ETL")
public void txnETL(
@Param("txId") String txId,
@Param("inId") String inId,
@Param("proc") String proc,
@Param("qtys") String qtys);
現在,這工作正常,期待當“proc”為空值時,在這種情況下它會拋出異常:
SEVERE: Servlet.service() for servlet [dispatcher] in context with path [/Authenticator]
threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException:
Error calling CallableStatement.getMoreResults; nested exception is org.hibernate.exception.GenericJDBCException:

如何處理空值? 將所有字符串設置為 "" 不提供空插入。
看起來 SP 調用中具有空值的參數是未解決的問題。 請參閱https://hibernate.atlassian.net/browse/HHH-9007
