在此 ResultSet Postgresql Spring Data JPA 中找不到列名答案

【问题描述】：

我在存储库接口中为表 items_table 创建了自己的方法。实体 ItemEntity 映射到 items_table 并提供了相同的 Entity 类。

package com.adhya.inventory.entity;

import java.sql.Types;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.Table;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;

import org.hibernate.annotations.GenericGenerator;
import org.hibernate.annotations.Type;

@Entity
@Table(name="ItemsTable")
public class ItemEntity {

    @Id
    @GenericGenerator(name="itemIdGen", strategy="com.adhya.inventory.entity.ItemIdGenerator")
    @GeneratedValue(generator="itemIdGen")
    private String itemId;

    private String itemType;
    
    @Min(value=0)
    private Double quantity;
    
    private Double costPrice;
    
    @Min(value=0)
    private Double sellingPrice;
    
    @NotNull
    private String color;
    
    private String material;
    
    private String store;
    
    private String details;
    
    @Lob
    private byte[] image;
    
    private String trader;
    
    private String status;
    
    public String getItemId() {
        return itemId;
    }
    public void setItemId(String itemId) {
        this.itemId = itemId;
    }
    public String getItemType() {
        return itemType;
    }
    public void setItemType(String itemType) {
        this.itemType = itemType;
    }
    public Double getQuantity() {
        return quantity;
    }
    public void setQuantity(Double quantity) {
        this.quantity = quantity;
    }
    public Double getCostPrice() {
        return costPrice;
    }
    public void setCostPrice(Double costPrice) {
        this.costPrice = costPrice;
    }
    public Double getSellingPrice() {
        return sellingPrice;
    }
    public void setSellingPrice(Double sellingPrice) {
        this.sellingPrice = sellingPrice;
    }
    public String getColor() {
        return color;
    }
    public void setColor(String color) {
        this.color = color;
    }
    public String getMaterial() {
        return material;
    }
    public void setMaterial(String material) {
        this.material = material;
    }
    public String getStore() {
        return store;
    }
    public void setStore(String store) {
        this.store = store;
    }
    public String getDetails() {
        return details;
    }
    public void setDetails(String details) {
        this.details = details;
    }
    public byte[] getImage() {
        return image;
    }
    public void setImage(byte[] image) {
        this.image = image;
    }
    public String getTrader() {
        return trader;
    }
    public void setTrader(String trader) {
        this.trader = trader;
    }
    public String getStatus() {
        return status;
    }
    public void setStatus(String status) {
        this.status = status;
    }
}

pgAdmin中items_table的列视图如下： Columns in items_table

以下自定义查询不起作用：

@Query(value="SELECT item_id from public.items_table where lower(CONCAT(item_id,' ', color,' ',details,' ',material,' ',quantity,' ',selling_price,' ',trader)) like all ('{\"%blue%\", \"%silk%\"}') and store='Main' and status='In Stock' and item_type='Container'", nativeQuery = true)

相同的方法签名是：

List<ItemEntity> search(@Param("hs") Set<String> hs, @Param("itemType") String itemType, @Param("itemStatus") String itemStatus,@Param("store") String store);

异常堆栈跟踪的主要部分是

The column name color was not found in this ResultSet.

完整的堆栈跟踪信息供您参考：

org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute query; SQL [SELECT item_id from public.items_table where lower(CONCAT(item_id,' ', Color,' ',details,' ',material,' ',quantity,' ',selling_price,' ',trader)) like all ('{"%blue%", "%silk%"}') and store='Anjali Rama Market' and status='In Stock' and item_type='Saree']; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query

【问题讨论】：

什么是存储库方法签名？
@crizzis 签名已添加到问题中。谢谢
既然您选择的是实体列表，为什么不SELECT *？
@crizzis 感谢您指出这一点，这是我的粗心。我正在尝试使用过滤器并使用 like 运算符实现自定义搜索，但由于其中一列包含图像，因此脚本出错了，以避免每次我只是选择导致错误的 id 时获取它，因为结果不包含任何其他列。

标签： spring postgresql hibernate jpa spring-data-jpa

【解决方案1】：

这引起了我的注意——顶部查询是堆栈跟踪中的查询，底部是@Query 中的查询。错误的有“颜色”与“颜色”。如果您在引号Are PostgreSQL column names case-sensitive? 中定义列，Postgresql 可能会区分大小写。在 Postgresql 工具中尝试这两个查询，因为异常源自 Postgresql - 剥离所有 Java 层以简化调试。

SELECT item_id from public.items_table where lower(CONCAT(item_id,' ', Color,' ',details,' ',material,' ',quantity,' ',selling_price,' ',trader)) like all ('{"%blue%", "%silk%"}') and store='Anjali Rama Market' and status='In Stock' and item_type='Saree'

SELECT item_id from public.items_table where lower(CONCAT(item_id,' ', color,' ',details,' ',material,' ',quantity,' ',selling_price,' ',trader)) like all ('{\"%blue%\", \"%silk%\"}') and store='Main' and status='In Stock' and item_type='Container'
