从Spring Boot调用Oracle PL / SQL函数时出错

Question

我有一个连接到Oracle DB的Spring Boot应用程序。 该DB具有大量用PL/SQL编写的存储过程和函数。

我试图调用一个非常简单的PL/SQL函数，该函数将字符串作为输入并返回字符串作为输出。 但是我在打电话时遇到了一个例外。

错误：

PLS-00306: wrong number or types of arguments in call to 'CHECK_ACTIVE_APPL'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

PL / SQL功能：

FUNCTION CHECK_ACTIVE_APPL (appl IN VARCHAR2)
RETURN VARCHAR2 AS
  activeFlag VARCHAR2(1);
  BEGIN
    SELECT appl_actv_cd INTO activeFlag FROM   link_appl WHERE  appl_id=appl;
    RETURN activeFlag;
END CHECK_ACTIVE_APPL;

Answer 1

最后，此SO链接（ 如何使用Hibernate（EntityManager）或JPA 2调用Oracle函数或过程 ）和本文（ https://vladmihalcea.com/how-to-call-oracle-stored-procedures-and-functions- from-hibernate / ）帮助我解决了问题。 为使事情正常进行，我进行了一些更改。

LinkAppl.java

@Entity
@Table(name = "LINK_APPL")
public class LinkAppl {
    private String applId;
    private String applDeTx;
    private String seqNbResetCd;
    private String intfMsgFrmtCd;
    private String sndRcvCd;
    private String applAcptMsgFrmtCd;
    private String applActvCd;
    private String sodEodIn;
    private String linkNotesTx;
    private String lastModByUsrId;
    private Timestamp lastModTs;
    private String sndCnctStsCd;
    private Long maxSeqNb;
    private String batIntfIn;
    private String gfpSrcSiteCd;
    private String rcvRterAckmentIn;
    private String rcvMqCodIn;
    private String fxApplIn;
    private String rcvEodpAckmentIn;
}

LinkApplService.java

@Service
@Log4j2
public class LinkApplService {

    private static final String CHECK_ACTIVE_APPL_QUERY = "select PKG_USROUTER.CHECK_ACTIVE_APPL(:appl) from DUAL";

    @PersistenceContext
    private EntityManager em;
    @Autowired
    private LinkApplRepository linkApplRepository;

    public String checkApplicationActive(String applicationId) {
        String activeFlag = (String) em.createNativeQuery(CHECK_ACTIVE_APPL_QUERY)
                .setParameter("appl", applicationId)
                .getSingleResult();
        log.debug("activeFlag: " + activeFlag);
        return activeFlag;
    }

}

LinkApplController.java

@Controller
@RequestMapping("/applications")
@Log4j2
public class LinkApplController {

    @Autowired
    private LinkApplService linkApplService;

    @GetMapping
    public String getAllApplLinks(Model model) {
        String activeFlag = linkApplService.checkApplicationActive("TITAN");
        log.debug("@@@@@@@@@@@@@@@@activeFlag: " + activeFlag);
        model.addAttribute("activeFlag", activeFlag);    
        return "index";
    }
}
