System.out.printf("%.2f", 1.323);
console1.32
I use @JSONField(format = "%.2f")
for Double
&String
&Float
& BigDecimal
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.annotation.JSONField;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.math.BigDecimal;
@Data
@NoArgsConstructor
public class RunTest {
@JSONField(format = "%.2f")
private Double d0;
@JSONField(format = "%.2f")
private String d1;
@JSONField(format = "%.2f")
private Float d2;
@JSONField(format = "%.2f")
private BigDecimal d3;
public static void main(String[] args) {
System.out.printf("%.2f", 1.323);
RunTest runTest = JSON.parseObject("{\n" +
" \"d0\": 1.323,\n" +
" \"d1\":1.323,\n" +
" \"d2\": 1.323,\n" +
" \"d3\":1.323\n" +
"}", RunTest.class);
}
}
I hope value is 1.32
What should I do?

maybe don't have the method ,you can try to use deserializeUsing and write your own deserialize class
