Spring JPA SQLException：从数据类型INTO到CHAR的隐式转换

当通过Spring JPA在ClientAccount和ProductDescription之间进行JOIN时发生隐式转换错误。我不确定转换发生在哪里。我正在使用Sybase。Spring JPA SQLException：从数据类型INTO到CHAR的隐式转换

错误：

ProductDescription SQL Table Schema

谁能帮助确定我可能是错的？

您的主键定义在哪里？据我所知，您需要在JPA – mrkernelpanic

中至少定义一个我在原始文章中添加了主键的快照。 – user3712237

为什么到处使用'insertable = false，updatable = false'？请添加完整的异常堆栈？其次，关系'ProductDescription'''ClientAccount'应该拥有关联关系之一，我建议你使用@OneToMany和'mappedby'（两边都不需要@JoinColumn），你可以写'@OneToMany（fetch = FetchType.LAZY，mappedBy =“clientAccount”）' –

在您的ProductDescriptionkey类中将字符串中的productId类型更改为Integer或Long，因为这代表您的主键。

我刚试过，它给了我同样的错误。我在原始文章中添加了堆栈跟踪。有没有办法在ProductDescriptionKey中添加转换为属性？ – user3712237

我无法从异常多的信息，但我会努力纠正一些映射问题，它可能会导致异常

首先：ClientAccount.java应该是（因为你使用双向关联）：

@Table(name="ClientAccount") 
@Entity 
@Getter 
@Setter 
public class ClientAccount { 

    @EmbeddedId 
    private ClientAccountKey key; 

    @OneToMany (fetch = FetchType.LAZY, mappedBy = "clientAccount") 
    private List<ProductDescription> productDescription;  
}

ProductDescriptionKey.java

Table(name="ProductDescription") 
@Entity 
@Getter 
@Setter 
public class ProductDescription { 

    @EmbeddedId 
    private ProductDescriptionKey key; 

    @Column(name = "Description", insertable = false, updatable = false) 
    private String description; 

    @ManyToOne 
    @JoinColumns({ 
     @JoinColumn(name="ClientAccountKeyField1_Fk_ColumnName", referencedColumnName = "ClientAccountKeyField1_Pk_ColumnName"), 
     @JoinColumn(name="ClientAccountKeyField2_Fk_ColumnName", referencedColumnName = "ClientAccountKeyField2_Pk_ColumnName"), 
//... other @JoinColumn 
    }) 
    private ClientAccount clientAccount; 
}

你可能注意到了，在@JoinColumn您应该使用ClientAccountKey字段，而不是ProductDescriptionKey，因为这些列将在ProductDescription中创建，以引用ClientAccount行。

...，并使用@JoinColumns时，您应该使用referencedColumnName，如文档中表示：

When the JoinColumns annotation is used, both the name and the referencedColumnName elements must be specified in each such JoinColumn annotation

二：我不认为这是ProductDescriptionKey类使用insertable = false, updatable = false一个好主意，因为你应该有一个ID要坚持。但是，如果您想要只读实体，请改用@Immutabl。

希望它解决了这个问题！
