可以使用Java的String类中的getBytes方法，将字符串转换为字节数组，再使用Java的DatatypeConverter类中的printHexBinary方法将字节数组转换为16进制字符串。示例代码如下：

import javax.xml.bind.DatatypeConverter;

public class HexConverter {
    public static String convertToHex(String input) {
        byte[] bytes = input.getBytes();
        return DatatypeConverter.printHexBinary(bytes);
    }
}

使用方法：

String input = "OrderBodys { otaOrderSn = '1234567234', orderSeedSn = 'null', refundQuantity = NULL, voucherCode = 'null', orderSn = '123456344234', totalPrice = 2, totalCostPrice = 2, NAME = '大毛', mobile = '18888888888', idCard = '', seeds =[ Seeds { orderSeedSn = '2354434654', productCode = 'abcdef', price = 1, totalPrice = 1, quantity = 1, NAME = '大毛', mobile = '18888888888', idCard = '', voucherCode = '7934734276', travelDate = '2020-08-08' }, Seeds { orderSeedSn = '641428356', productCode = 'asxdaq', price = 2, totalPrice = 4, quantity = 6, NAME = '小毛', mobile = '18756788225', idCard = '', voucherCode = '9856322478', travelDate = '2021-09-08' }]}";
String output = HexConverter.convertToHex(input);
System.out.println(output);

输出结果：
