在 Hibernate/Oracle 上執行批量更新/插入時出現異常

Question

我在將對象持久保存到數據庫中時遇到異常，下面是代碼庫模型：

@Entity
@Table(name = "customer_data")
public class BsslpCustomerInfo {
    @Id
    @Column(name = "id", length = 10)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    @Column(name = "service_Id", length = 50, unique = true, nullable = false)
    private String serviceId;

    @Column(name = "quarter", length = 255, nullable = false)
    private String quarter;

    @Column(name = "year")
    private int year;

    @Column(name = "activated_Customer_Name")
    private String activatedCustomerName;

    @Column(name = "deactivated_Customer_Name")
    private String deactivatedCustomerName;

    @Column(name = "quarter_Start_Date")
    private String quarterStartDate;

    @Column(name = "quarter_End_Date")
    private String quarterEndDate;

    public String getServiceId() {
        return serviceId;
    }

    public void setServiceId(String serviceId) {
        this.serviceId = serviceId;
    }

    public String getQuarter() {
        return quarter;
    }

    public void setQuarter(String quarter) {
        this.quarter = quarter;
    }

    public int getYear() {
        return year;
    }

    public void setYear(int year) {
        this.year = year;
    }

    public String getActivatedCustomerName() {
        return activatedCustomerName;
    }

    public void setActivatedCustomerName(String activatedCustomerName) {
        this.activatedCustomerName = activatedCustomerName;
    }

    public String getDeactivatedCustomerName() {
        return deactivatedCustomerName;
    }

    public void setDeactivatedCustomerName(String deactivatedCustomerName) {
        this.deactivatedCustomerName = deactivatedCustomerName;
    }

    public String getQuarterStartDate() {
        return quarterStartDate;
    }

    public void setQuarterStartDate(String quarterStartDate) {
        this.quarterStartDate = quarterStartDate;
    }

    public String getQuarterEndDate() {
        return quarterEndDate;
    }

    public void setQuarterEndDate(String quarterEndDate) {
        this.quarterEndDate = quarterEndDate;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }
}

...這是“控制器”代碼：

for (BsslpParty bsslp : data) {
    Date activationDate = sdf.parse(bsslp.getAssocStartDate());
    Date deactivationDate = sdf.parse(bsslp.getAssocEndDate());
    if(activationDate.compareTo(startDate)>=0 && activationDate.compareTo(endDate)<=0){
        activeCount++;
        BsslpCustomerInfo bsslpCustomerInfo = new BsslpCustomerInfo();
        bsslpCustomerInfo.setServiceId(bsslp.getBsslpName());
        bsslpCustomerInfo.setActivatedCustomerName(bsslp.getEntitledPartyName());
        bsslpCustomerInfo.setQuarter(quarterDateRange.getStartdate());
        bsslpCustomerInfo.setYear(quarterDateRange.getFinYear());
        bsslpCustomerInfo.setQuarterStartDate(quarterDateRange.getStartdate());
        bsslpCustomerInfo.setQuarterEndDate(quarterDateRange.getEndDate());
        listOfActDeActCust.add(bsslpCustomerInfo);              
    }

    usageMetricschartService.saveAllCustomerData(listOfActDeActCust);
}

“服務”實現：

@Override
@Transactional
public void saveAllCustomerData(List<BsslpCustomerInfo> customersData) {
    // TODO Auto-generated method stub

    for (BsslpCustomerInfo bsslpCustomerInfo : customersData) {
        usageMetricsCustomersRepository.save(bsslpCustomerInfo);
    }

}

它拋出一個錯誤，如：

java.sql.BatchUpdateException: ORA-01722: 無效數字

oracle.jdbc.driver.DatabaseError.throwBatchUpdateException(DatabaseError.java:343) org.springframework.dao.InvalidDataAccessResourceUsageException：無法執行批處理； SQL [插入customer_data (activated_Customer_Name、deactivated_Customer_Name、quad、quority_End_Date、quarter_Start_Date、service_Id、year、id) 值(?, ?, ?, ?, ?, ?, ?, ?)]; 嵌套異常是 org.hibernate.exception.SQLGrammarException: 無法執行批處理

我嘗試了所有可能的方法都無法解決這個問題； 任何人都可以幫助我嗎？

Answer 1

您已將id定義為自動生成，但對於您創建的每個實體，您都將 0 值傳遞給數據庫。 這是因為您使用的原始int類型默認初始化為 0。如果您為id字段設置一個值，則不會自動生成。

將id屬性更改為Integer類型，以便在持久化時將空值發送到 JPA，這將導致生成 id。
