我很高兴参与这个网站。我是 Stack Overflow 的新手，但总有第一次 :)。

目前我正在使用 Spring Data 1.3.0 和 Hibernate 4.1.9，使用 JPA 2.0 over Java 生成基于存储库的查询，数据库是 SQL Server 2008。我需要使用两个表进行插入操作：A模式表称为 PATTERN_TABLE。该表被另一个称为 CHILD_TABLE 的表引用，它们的关系是一对多的。我针对此要求开发解决方案的指南是以下链接：Hibernate one-to-many mapping using annotations，并且我正在尝试将其调整为弹簧数据支持（存储库管理）。但是它失败了，因为 Hibernate 对于插入，尝试查找 CHILD_TABLE 表（在数据库中）和映射实体中不存在的列。我不知道为什么 Hibernate 会试图找到这个列名，我认为它是一个别名（称为 patternTable_CODIGO）。该错误由以下日志注册表定义：

Hibernate: insert into GDA.dbo.PATTERN_TABLE (COLUMN_A, COLUMN_B, COLUMN_C, COLUMN_D) values (?, ?, ?, ?)
(...)
Hibernate: insert into GDA.dbo.CHILD_TABLE (COLUMN_CHILD_A, COLUMN_CHILD_B, patternTable_CODIGO) values (?, ?, ?) --->patternTable_CODIGO doesn't exists in the database!!!

这是PatternTable实体：

package co.com.myproject.persistencia;
// ... libraries
import javax.persistence.*;

@Entity
@Table(name = "PATTERN_TABLE", schema = "dbo", catalog = "GDA")
public class PatternTable implements Serializable {
    private static final long serialVersionUID = 1L;
    private int codigo;

    // ... a lot of mapped fields...

    private Set<ChildTable> childTable = new HashSet<ChildTable>(0);

    public PatternTable() {}

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "CODIGO")
    public int getCodigo() {
            return codigo;
    }

    public void setCodigo(int codigo) {
            this.codigo = codigo;
    }

    // ... a lot of getters and setters...

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name="CODIGO_PATTERN_TABLE")
    public Set<ChildTable> getChildTable() {
            return childTable;
    }

    public void setChildTable(Set<ChildTable> childTable) {
            this.childTable = childTable;
    }
}

这是ChildTable实体

package co.com.myproject.persistencia;
//... libs
@Entity
@Table(name = "CHILD_TABLE", schema = "dbo", catalog = "GDA")
public class ChildTable implements java.io.Serializable {

    private static final long serialVersionUID = 1L;
    private int codigo;
    private PatternTable patternTable;
    //... more attribures

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "CODIGO", unique = true, nullable = false)
    public int getCodigo() {
            return codigo;
    }

    public void setCodigo(int codigo) {
    this.codigo = codigo;
}

@ManyToOne
public PatternTable getPatternTable() {
    return patternTable;
}

public void setPatternTable(PatternTable patternTable) {
    this.patternTable = patternTable;
}

// ... more getters and setters
}

这是我的存储库接口PatternTable：

@Transactional(readOnly = true)
public interface PatternTableRepository extends JpaRepository<PatternTable, Integer> {
    List<PatternTable> findByPatternParameter(String patternParameter);
    // ... more code next
}

我的服务方法定义为：

public void guardar(PatternTable patternTable) {
    patternTableRepository.save(patternTable);
}

并且patternTable' 对象childTable通过以下方式收集一个或多个：

childTable = new ChildTable();
//...set attributes of childTable...
patternTable.getChildTable().add(childTable);

如果我的英语不流利，我很抱歉。我会尝试找到一个解决方案，但如果你能帮助我，我将不胜感激。非常感谢！:)

嗯......我不能为这个麻烦开发出我理想的解决方案，但我可以开发一个非常快速和简单的解决方案。这工作如下：

  1. 在实体 beanPatternTable中编写一些更改。ChildTable在ChildTable@ManyToOne 注释之后，添加 FetchType 和 JoinColumn，如下所示：

    //Entity definition and getters / setters...        
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "CODIGO_PATTERN_TABLE", nullable = false)
public PatternTable getPatternTable() {
    return patternTable;
}
//More getters and setters...

    此外，在PatternTable实体 bean 中，修改 @OneToMany 关系如下：

    //Entity definition and getters / setters... 
@OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, mappedBy = "patternTable")
public Set<ChildTable> getChildTable() {
    return childTable;
}
//More getters and setters...

  2. 修改实体 bean 的保存方法。第一次，我保存了没有 Set of s的PatternTable实体 bean 。ChildTable之后，我将ChildTables' 集与它们各自的集合相关联，PatternTable并创建了一个新的存储库ChildTable来保存这些。

非常感谢您查看这个问题，并为我糟糕的英语感到抱歉！:)
