java.lang.NumberFormatException：對於從數據庫獲取數據時的輸入字符串XX

我試圖從數據庫中獲取數據。我收到以下錯誤。java.lang.NumberFormatException：對於從數據庫獲取數據時的輸入字符串XX

[Request processing failed; nested exception is org.hibernate.exception.GenericJDBCException: An error occurred while converting the nvarchar value to JDBC data type INTEGER.] with root cause 
java.lang.NumberFormatException: For input string: "XX"

我知道它試圖將我的字符串轉換爲整數。但我不明白爲什麼這樣做，因爲我的數據類型只是字符串。

我的代碼如下所示：

型號：

package com.a.spring.models; 

import java.util.Date; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.JoinColumn; 
import javax.persistence.OneToOne; 
import javax.persistence.Table; 


@Entity 
@Table(name="CapacityConstraint") 
public class CapacityConstraint { 


    private int DocEntry; 
    private String OpCode; 
    private String RsrcCd; 
    private String Type; 
    private Operation operation; 

    @Id 
    @Column(name="DocEntry") 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    public int getDocEntry() { 
     return DocEntry; 
    } 


    public void setDocEntry(int DocEntry) { 
     this.DocEntry = DocEntry; 
    } 


    @Column(name="OpCode") 
    public String getOpCode() { 
     return OpCode; 
    } 


    public void setOpCode(String opCode) { 
     OpCode = opCode; 
    } 


    @Column(name="RsrcCd") 
    public String getRsrcCd() { 
     return RsrcCd; 
    } 


    public void setRsrcCd(String rsrcCd) { 
     RsrcCd = rsrcCd; 
    } 


    @Column(name="Type") 
    public String getType() { 
     return Type; 
    } 


    public void setType(String type) { 
     Type = type; 
    } 

    @OneToOne 
    @JoinColumn(name = "OpCode", nullable = false, insertable = false, updatable = false) 
    public Operation getOperation() { 
     return operation; 
    } 


    public void setOperation(Operation operation) { 
     this.operation = operation; 
    } 


}

操作模式：

@Entity 
@Table(name="[@IS_OPRMASTER]") 
public class Operation { 
    private int docEntry; 
    private String OpCode; 
    private String OpName; 

    @Id 
    @Column(name="DocEntry") 

    public int getDocEntry() { 
     return docEntry; 
    } 
    public void setDocEntry(int docEntry) { 
     this.docEntry = docEntry; 
    } 

    @Column(name="U_OpCode") 
    public String getOpCode() { 
     return OpCode; 
    } 
    public void setOpCode(String opCode) { 
     OpCode = opCode; 
    } 
    @Column(name="U_OpName") 
    public String getOpName() { 
     return OpName; 
    } 
    public void setOpName(String opName) { 
     OpName = opName; 
    } 

}

功能來獲取數據：

@Override 
    public List<CapacityConstraint> getList() { 
     Session session = sessionFactory.getCurrentSession(); 
     Query query= session.createSQLQuery("SELECT * FROM CapacityConstraint order by docEntry").addEntity(CapacityConstraint.class); 
     List <CapacityConstraint> d=query.list(); 
     return d; 
    }

表capacityconstraint

CREATE TABLE [dbo].[CapacityConstraint](
    [DocEntry] [numeric](18, 0) IDENTITY(1,1) NOT NULL, 
    [OpCode] [nvarchar](50) NULL, 
    [RsrcCd] [nvarchar](50) NULL, 
    [Type] [nvarchar](50) NULL, 
    CONSTRAINT [PK_CapacityConstraint] PRIMARY KEY CLUSTERED 
(
    [DocEntry] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
) ON [PRIMARY]

表操作

CREATE TABLE [dbo].[@IS_OPRMASTER](
    [DocEntry] [int] NOT NULL, 
    [U_OpCode] [nvarchar](20) NULL, 
    [U_OpName] [nvarchar](100) NULL, 
CONSTRAINT [KIS_OPRMASTER_PR] PRIMARY KEY CLUSTERED 
(
    [DocEntry] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
) ON [PRIMARY]

這是給錯誤的操作碼。如果我從capacityConstraint模型中刪除操作模型，那麼它工作正常，不會出現任何錯誤。但是如果我包含它，那麼它會拋出錯誤。所以我認爲問題是與@joinColumn語句。

我真的很感激，如果有人能解決我的問題。

在此先感謝。

'XX'是二十個右邊。 –

也許'docEntry'不是int。請發佈您的表架構 –

XX是一個字符串。 – mona

我認爲你是有身分的同名2列，

@Column（name = 「操作碼」）
公共字符串getOpCode（）{
返回操作碼;
}

和

@OneToOne
@JoinColumn（name = 「操作碼」，可爲空=假，可插入 =假，可更新= FALSE）
公共操作getOperation（）{ 返回操作; }

一個對象引用（外鍵）一個字符串，所以他們中的一個人試圖在整數格式轉換爲字符串格式外鍵和一個。

你好Rupesh，我試着改變joincolumn語句中的列名。但它給我列名稱U_OpCode無效。 @JoinColumn（name =「OpCode」，...）中的 – mona

名稱應該是您的表CapacityConstraint中具有用於@IS_OPRMASTER外鍵的列的名稱，此列缺失。 – Rupesh
