java.lang.NumberFormatException : For input string XX while fetching the data from the database

标签 java spring hibernate jdbc numberformatexception

我正在尝试从数据库中获取数据。我收到以下错误。

[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"

我知道它正在尝试将我的字符串转换为整数。但我不明白为什么要这样做，因为我的数据类型只是字符串。

我的代码如下:

型号:

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;
    }


}

运营模式:

@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;
    }

}

获取数据的函数:

@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;
    }

表容量约束

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]

它给出了操作码错误。如果我从容量约束模型中删除操作模型，那么它可以正常工作，不会出现任何错误。但如果我包含它，它就会抛出错误。 所以我认为问题出在 @joinColumn 语句上。

如果有人能解决我的问题，我将非常感激。

提前致谢。

最佳答案

我认为您正在用相同的名称命名 2 列，

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

和

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

一个用于对象引用(外键)，一个用于字符串，因此其中之一尝试将外键转换为整数格式，另一者尝试将其转换为字符串格式。
