Java InvalidDataAccessResourceUsageException:无法提取结果集 简介

我继承了一个项目，正在尝试进行更改。 在我向实体添加以下字段和方法之前，web应用程序工作正常

@Lob
@Column(name = "FIELDS")
private String partnerFields;

public String getPartnerFields() {
    return partnerFields;
}

public void setPartnerFields(String partnerFields) {
    this.partnerFields = partnerFields;
}

错误 添加这些后，我会出现以下错误：

补充资料 代码是专有的，所以我不能全部发布，但我还可以补充，错误发生在

findAll

方法调用中，该调用将

规范

作为参数

1。findAll调用

引发异常的行：

return partnerRepository.findAll(PartnerSpecifications.isForSelection(selectionFilter), pageable);

这就是所谓的特定JPA方法：

2。由Hibernate显示的SQL语句

以下是SQL语句的编辑版本，其中大部分列已删除：

SELECT * 
FROM   (SELECT DISTINCT partnerent0_.partner_id                 AS 
                        PARTNER_ID1_16_, 
                        ...
        FROM   partner partnerent0_, 
               partner_id partneride1_ 
        WHERE  partnerent0_.id = partneride1_.id 
               AND ( partnerent0_.status IS NOT NULL ) 
               AND partnerent0_.status <>? 
               AND ( partneride1_.identifier LIKE ? ) 
               AND ( partnerent0_.cat2016 <>?  OR partnerent0_.category_2016 IS NULL )
               )

我的新实体（1对1）：

 @OneToOne(cascade = CascadeType.ALL, mappedBy = "partner")
    private PartnerFieldsEntity partnerFieldsEntity;

@Entity
@Table(name="PARTNER_FIELDS")
public class PartnerFieldsEntity{

    @Id
    @OneToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "PARTNER_ID", nullable = false)
    private PartnerEntity partner;

    @Lob
    @Column(name = "FIELDS")
    private String partnerFields;

    public PartnerEntity getPartner() {
        return partner;
    }

    public void setPartner(PartnerEntity partner) {
        this.partner = partner;
    }

    public String getPartnerFields() {
        return partnerFields;
    }

    public void setPartnerFields(String partnerFields) {
        this.partnerFields = partnerFields;
    }

    public void setPartnerFields(PartnerFieldsWrapper projectFields) {
        setPartnerFields(projectFields.toJson());
    }

}

Oracle 10中的

SELECT DISTINCT

需要

UNION

，而

CLOB

不支持此操作。您必须使用

DISTINCT

的替代方法。另外，不要在

WHERE

语句中包含

CLOB

列。

Yes。。。我检查了一下，确实有

query.distinct（true）。我将不加区分地试一试。您的来源：：）找不到适合我的工作解决方案。可能情况不同
