java - 错误 SqlExceptionHelper - 整数值不正确

Question

错误 SqlExceptionHelper - 整数值不正确:'\xAC\xED\x00\x05sr\x00!com.domain.Client\xF3\xA5\x02\x0E\xC5d.\xA2\x02\x00\x0AJ\x00\x09clientKeyL第 1 行“ClientKey”列的\x00\x0AclientN'

我的道如下

@Entity
@Table(name = "M_FeedInputParams")
public class FeedInputParams {

    private Client clientKey;
@Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "ParamKey")
    private long paramKey;

    public long getParamKey() {
        return paramKey;
    }

    @Column(name = "FeedKey")
    public long getFeedKey() {
        return feedKey;
    }

    public void setFeedKey(long feedKey) {
        this.feedKey = feedKey;
    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "clientKey")
    @Column(name="ClientKey")
    public Client getClientKey() {
        return clientKey;
    }

    public void setClientKey(Client client) {
        this.clientKey = client;
    }}

首先，我设置了客户端表的客户端 key ，并将客户端传递给 FeedInputParams 。当我执行时，它给出了错误，客户端 key 很长，并且在数据库中为 bigint(20)

Answer 1

注释放置不正确。应该在注释字段或注释方法之间做出决定。 JPA 2.0 规范中对此进行了如下说明。

It is an error if a default access type cannot be determined and an access type is not explicitly specified by means of annotations or the XML descriptor. The behavior of applications that mix the placement of annotations on fields and properties within an entity hierarchy without explicitly specifying the Access annotation is undefined.

在这种特定情况下，Hibernate 根据 paramKey 中的 @Id 注释决定首选基于字段的访问。因此，getClientKey 方法中的注释将被忽略。可以通过将注释从 getClientKey 方法移动到 clientKey 字段来解决问题。

如果混合访问是首选，则 @Access应该使用。
