如何解决Java中的NumberFormatException？

表字段

Field: Bank_Account_No
Type : int(100)

这是我的带有setter/getter方法的“account”模型

@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。但当我插入“123456789111111”时，它抛出NumberFormatException

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

这里是Trach：

如果查看stacktrace，您会看到

java.lang.Integer.parseInt

您提供的数字太大，超出了整数范围。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位有符号2的补码 整数，最小值为-231，最大值为 231-1. 在JavaSE8和更高版本中，可以使用int数据类型 表示最小值为0的无符号32位整数 最大值为232-1。使用Integer类来使用int数据 键入一个无符号整数。请参见课程编号部分 更多信息。静态方法，如compareUnsigned、divideUnsigned etc已添加到Integer类以支持该算法 无符号整数的运算

来源：

整数

数字超出范围。将您的类型更改为

Long

整数值应介于两者之间

一个常量，包含一个int可以具有的最大值，

2^31-1

。 i、 e

2147483647

一个常量，它保存一个int可以具有的最小值，

-2^31

。即

2147483648

建议始终使用Long for id，因为它将占用64位，即

-2^63

数字超出范围<代码>“123456789111111”是一个长数字

范围是什么：

。检查说明

上面的号码是123456789111111，即2147483647

（2^31-1），您希望使用Long而不是整数，因为如果您期望的数字那么大，Long最多可以是（9223372036854775807）。

对于标识字段，请使用Long而不是Integer。

---

十进制对于货币操作

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

有符号的long的最小值为-2^63，最大值为（2^63）-1。

Int数据类型是一个32位有符号2的补码整数。最小值为-2147483648。（-2^31）最大值为2147483647（包括）。（2^31-1）“123456789111111”大于java整数的最大值（max=2147483647，min=-2147483648）。好吧，您超出了

整数的最大值。如果您希望您的值如此大，那么使用
Long
，这意味着int（100）没有问题吗？什么是问题，为什么你建议长。谢谢你抽出时间@可能是来源。com@Ashish根据使用的位数，每种数据类型都有不同的范围。输入的数字需要更多的位来存储。在oracle站点上查看文档是适合您的类型。带符号的long的最小值为-2^63，最大值为2^63-1*（-922337e+18到922337e+18）。请看下面的内容，这是关于Java和C/C++之间差异的好信息。Java类型是标准的，因为一切都在JVM上运行。对于C/C++来说，类型根据机器的体系结构（）的不同而变化。问题已解决，改为Long。我还更改了数据表字段的BIGINT。谢谢@maythesource.comIt应该足以更改为Long。BigInteger用于更大的数字，但您不需要它。：-）\大家好。感谢allz。完成了对长型的更改。我还更改了BIGINT中的数据字段类型。谢谢。
