“无法执行保存操作：org.hibernate.exception.DataException：无法执行语句”使用 OpenXava？

【问题标题】："Impossible to execute Save action: org.hibernate.exception.DataException: could not execute statement" using OpenXava?“无法执行保存操作：org.hibernate.exception.DataException：无法执行语句”使用 OpenXava？

【问题描述】：

我是 Java 新手，需要一些帮助。我使用 OpenXava 创建了一个 @MappedSuperclass “与会者”。

import javax.persistence.*;
import org.hibernate.annotations.*;
import org.openxava.annotations.*;

@MappedSuperclass
public class Attendees {
    
    @Id @Hidden @Column(length = 3)
    @GeneratedValue(generator="system-uuid") @GenericGenerator(name="system-uuid", strategy="uuid")
    private String oid;

    public String getOid() {
        return oid;
    }
    public void setOid(String oid) {
        this.oid = oid;
    }
}

然后我将其扩展为另外两个类“员工”和“参与者”。

import javax.persistence.*;

@Entity
public class Staff extends Attendees{
    
    @Column (length = 50) 
    private String fullName;
    
    @Column (length = 2) 
    private int age;

    @Column (length = 10) 
    private int contactNum;
    
    @Embedded 
    private Address address; 

    @Embedded
    private MedicalInformation medicalInfo;


... 
}

和

import javax.persistence.*;

@Entity
public class Participants extends Attendees{
    
    @Column (length = 50) 
    private String fullName;
    
    @Column (length = 2) 
    private int age;

    @Column (length = 10) 
    private int contactNum;
    
    @Embedded 
    private Address address; 

    @Embedded
    private MedicalInformation medicalInfo;

...
}

下面是两个@Embedded 元素的代码：

地址：

import javax.persistence.*;

@Embeddable
public class Address {
    
    @Column(length = 100)
    private String street;
    
    @Column(length = 100)
    private String suburb;
 
    @Column(length = 100)
    private String city;
 
    @Column(length = 100)
    private String province;
    
    @Column(length = 5)
    private int areaCode;

...
}

和

医疗信息：

import javax.persistence.*;

@Embeddable
public class MedicalInformation {
    
    @Column (length = 3)
    private String dailyMedication;
    
    @Column (length = 300)
    private String medicationDescription;
    
    @Column (length = 300)
    private String allergies;
    
    @Column (length = 300)
    private String dietRequirements;
    
    @Column (length = 300)
    private String additionalNotes;

...
}

除了 Attendees 类之外，我省略了所有 getters() 和 setters()。

我将应用程序作为 Java 应用程序运行，它一直工作到我尝试输入和保存记录为止。当我点击“保存”时，系统会提示我：

 Impossible to execute Save action: org.hibernate.exception.DataException: could not execute statement

在 OpenXava 的控制台中仔细检查后，我发现以下内容：

我在这里没有提到的应用程序中的其他实体，请允许我保存新记录。然而，这些实体与提供的代码没有链接或相关。

请帮忙。

    【解决方案1】：

    变化：

    @Id @Hidden @Column(length = 3)
@GeneratedValue(generator="system-uuid") @GenericGenerator(name="system-uuid", strategy="uuid")
private String oid;

    作者：

    @Id @Hidden @Column(length = 32)
@GeneratedValue(generator="system-uuid") @GenericGenerator(name="system-uuid", strategy="uuid")
private String oid;

    注意@Column(length = 32) 而不是@Column(length = 3)。此外，您必须删除您的表以便 OpenXava 再次生成它们，如果它们已经有数据，只需执行 ALTER TABLE 来更改 OID 列的列长度。

      【解决方案2】：

      错误很明显：

      "SQLDataException: 数据异常：字符串数据，右截断；表：PARTICIPANTS 列：OID"

      问题出在 Participants 表中的 OID 列中（您尝试插入的字符串由于某种原因被截断），它可能与 jamie 所说的有关：
