Question

表格字段

Field: Bank_Account_No
Type : int(100)

这是我的“帐户”模型，带有setter / getter方法

@Entity
@Table(name = "account")
public class Account {

@Column(name = "Pharmacy_Account_No")
private Integer pharmacyAccountNo;

public Integer getPharmacyAccountNo() {
    return pharmacyAccountNo;
}

public void setPharmacyAccountNo(Integer pharmacyAccountNo) {
    this.pharmacyAccountNo = pharmacyAccountNo;
   }
}

如果我插入“1234567891”，它将成功添加。但是当我插入“123456789111111”时，它会抛出NumberFormatException

Inserting Code:
pharmacyAccount.setPharmacyAccountNo(request.getParameter("pharmacyAccountNo"). != null
                        && !request.getParameter("pharmacyAccountNo").equals("")
                                ? Integer.valueOf(request.getParameter("pharmacyAccountNo") : 0);

这里是StackTrach：

Answer 1

如果您查看堆栈跟踪，就会看到java.lang.Integer.parseInt

您提供的数字太大，不在整数范围之内。您应该尝试使用Long。

如果您查看oracle网站上的文档：

int：默认情况下，int数据类型是32位带符号的二进制补码整数，最小值为-231，最大值为 231-1。在Java SE 8及更高版本中，您可以使用int数据类型表示无符号的32位整数，其最小值为0 最大值为232-1。使用Integer类来使用int数据键入无符号整数。请参阅“数字类”一节更多信息。静态方法，如compareUnsigned，divideUnsigned 等已添加到Integer类以支持算术无符号整数的运算。

Answer 2

Integer数字超出范围。将您的类型更改为Long。

整数值应介于

之间

保持int可以具有的最大值的常量2 ^31-1。即2147483647

保持int可以具有的最小值的常量，-2^31。即2147483648

始终建议对Ids使用Long，因为它需要64位，即

2^ 63-1 - -2^63

Answer 3

数量超出范围。 "123456789111111"是一个很长的数字。

范围是什么：

              width                     minimum                         maximum
signed    8 bit                        -128                            +127
signed   16 bit                     -32 768                         +32 767
signed   32 bit              -2 147 483 648                  +2 147 483 647
signed   64 bit  -9 223 372 036 854 775 808      +9 223 372 036 854 775 807
unsigned  8 bit                           0                            +255
unsigned 16 bit                           0                         +65 535
unsigned 32 bit                           0                  +4 294 967 295
unsigned 64 bit                           0     +18 446 744 073 709 551 615

Reference。查看Integer了解说明

Answer 4

编号123,456,789,111,111高于Integer.MAX_INT，即2,147,483,647 （2 ^ 31-1），你想使用Long而不是Integer作为Long可以达到2^63-1（9,223,372,036,854,775,807），如果你期望那么大的麻木。

Answer 5

对IDENTITY字段使用长而不是整数。货币操作的十进制

Answer 6

如上所述，最好使用Long而不是Integer对象，因为这将允许您的应用程序处理大尺寸的数字。

签名长的最小值 -2 ^ 63 ，最大值（2 ^ 63） - 1。 < / p>

Int数据类型是32位带符号的二进制补码整数。最低值为 - 2,147,483,648。（ - 2 ^ 31）最大值为2,147,483,647（含）。（2 ^ 31 -1）
