数据模型设计转账记录应包含:交易ID、时间戳、转出/入账户、金额、备注等字段回执单需要额外包含银行logo、印章等视觉元素关键技术点使用JavaFX或iText生成PDF格式回执单通过BufferedImage实现截图效果使用SimpleDateFormat处理交易时间安全注意事项生成的虚拟数据必须添加明显的水印标识代码语言:txt复制
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Random;
public class VirtualTransferGenerator {
private static final String[] BANKS = {"中国工商银行","中国建设银行","中国银行"};
public static TransferRecord generateRecord() {
Random rand = new Random();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
return new TransferRecord(
"VIR" + System.currentTimeMillis(),
sdf.format(new Date()),
BANKS[rand.nextInt(BANKS.length)] + "(" + rand.nextInt(9999) + ")",
BANKS[rand.nextInt(BANKS.length)] + "(" + rand.nextInt(9999) + ")",
String.format("%.2f", rand.nextDouble() * 10000),
"测试用途-虚拟数据"
);
}
}
class TransferRecord {
String transactionId;
String timestamp;
String fromAccount;
String toAccount;
String amount;
String remark;
// 构造方法、getter/setter省略
}
