[BUG] BigDecimal反序列化可能报错 #3665
Description
问题描述
public class DeserializeBugDTO {
private String address;
private BigDecimal kwhIncome;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public BigDecimal getKwhIncome() {
return kwhIncome;
}
public void setKwhIncome(BigDecimal kwhIncome) {
this.kwhIncome = kwhIncome;
}
@Override
public String toString() {
return "DeserializeBugDTO{" +
"address='" + address + '\'' +
", kwhIncome=" + kwhIncome +
'}';
}
}
使用springmvc HttpMessageConverter 配置为fastjson版本，@RequestBody反序列化DeserializeBugDTO报错，当BigDecimal为空字符且在json串的最后时会报错，在前面不会报错。
{
"kwhIncome": "",
"address": "中国"
}
不会报错
{
"address": "中国",
"kwhIncome": ""
}
会报错
环境信息
- JDK信息： 1.8
相关日志输出
{
"address": "中国",
"kwhIncome": ""
}
