private Double amount;// 金额 1.ccbB2b ccbB2b.setPAYMENT(String.valueOf(advancePayment.getAmount())); 2、 String tOrderAmountStr = String.valueOf(advancePayment.getAmount()); tOrder.setOrderAmount(tOrderAmount); 3、bocb2b String orderAmount = String.valueOf(advancePayment.getAmount()); DecimalFormat df2 = new DecimalFormat("##0.00"); payObject.setOrderAmount(df2.format(Double.parseDouble(orderAmount))); 4. sdbb2b DecimalFormat df2 = new DecimalFormat("##0.00"); sdbB2bPayObject.setAmount(df2.format(advancePayment.getAmount())); 5. psbcb2c DecimalFormat df2 = new DecimalFormat("##0.00"); tranlistRow.setORDERAMT(String.valueOf(df2.format(advancePayment.getAmount())));//订单金额
