## 银联支付简单例子
|
||
|
||
#### 支付配置
|
||
|
||
```java
|
||
|
||
UnionPayConfigStorage unionPayConfigStorage = new UnionPayConfigStorage();
|
||
unionPayConfigStorage.setMerId("商户id");
|
||
unionPayConfigStorage.setKeyPublic("公钥，验签证书链格式： 中级证书路径;根证书路径");
|
||
unionPayConfigStorage.setKeyPrivate("私钥, 私钥证书格式： 私钥证书路径;私钥证书对应的密码");
|
||
unionPayConfigStorage.setNotifyUrl("异步回调地址");
|
||
unionPayConfigStorage.setReturnUrl("同步回调地址");
|
||
unionPayConfigStorage.setSignType("RSA2");
|
||
unionPayConfigStorage.setInputCharset("UTF-8");
|
||
//是否为测试账号，沙箱环境
|
||
unionPayConfigStorage.setTest(true);
|
||
|
||
```
|
||
|
||
#### 网络请求配置
|
||
|
||
```java
|
||
|
||
HttpConfigStorage httpConfigStorage = new HttpConfigStorage();
|
||
/* 网路代理配置 根据需求进行设置**/
|
||
//http代理地址
|
||
httpConfigStorage.setHttpProxyHost("192.168.1.69");
|
||
//代理端口
|
||
httpConfigStorage.setHttpProxyPort(3308);
|
||
//代理用户名
|
||
httpConfigStorage.setHttpProxyUsername("user");
|
||
//代理密码
|
||
httpConfigStorage.setHttpProxyPassword("password");
|
||
/* /网路代理配置 根据需求进行设置**/
|
||
|
||
/* 网络请求ssl证书 根据需求进行设置**/
|
||
//设置ssl证书路径
|
||
httpConfigStorage.setKeystorePath("证书绝对路径");
|
||
//设置ssl证书对应的密码
|
||
httpConfigStorage.setStorePassword("证书对应的密码");
|
||
/* /网络请求ssl证书**/
|
||
|
||
```
|
||
|
||
#### 创建支付服务
|
||
|
||
```java
|
||
|
||
UnionPayService service = new UnionPayService(unionPayConfigStorage);
|
||
|
||
unionPayConfigStorage.setCertSign(true);//是否为证书签名
|
||
|
||
```
|
||
|
||
#### 创建支付订单信息
|
||
|
||
```java
|
||
PayOrder payOrder = new PayOrder("订单title", "摘要", new BigDecimal(0.01) , new SimpleDateFormat("yyyyMMddHHmmss").format(System.currentTimeMillis()));
|
||
```
|
||
#### 网页支付
|
||
```java
|
||
// 手机网页支付（WAP支付）
|
||
payOrder.setTransactionType(UnionTransactionType.WAP);
|
||
// 网关支付
|
||
// payOrder.setTransactionType(UnionTransactionType.WEB);
|
||
// 企业网银支付（B2B支付）
|
||
// payOrder.setTransactionType(UnionTransactionType.B2B);
|
||
//获取支付所需的信息
|
||
Map directOrderInfo = service.orderInfo(payOrder);
|
||
//获取表单提交对应的字符串，将其序列化到页面即可,
|
||
String directHtml = service.buildRequest(directOrderInfo, MethodType.POST);
|
||
```
|
||
|
||
#### 主扫申请二维码交易
|
||
|
||
```java
|
||
payOrder.setTransactionType(UnionTransactionType.APPLY_QR_CODE);
|
||
BufferedImage image = service.genQrPay(payOrder);
|
||
```
|
||
|
||
#### 消费(被扫场景)待定
|
||
|
||
```java
|
||
payOrder.setTransactionType(UnionTransactionType.CONSUME);
|
||
payOrder.setAuthCode("C2B码(条码号),1-20位数字");
|
||
Map<String, Object> params = service.microPay(payOrder);
|
||
```
|
||
#### 消费撤销
|
||
|
||
```java
|
||
Map<String, Object> params = service.unionRefundOrConsumeUndo("原交易查询流水号", "订单号", new BigDecimal("退款金额" ),UnionTransactionType.CONSUME_UNDO);
|
||
|
||
```
|
||
#### 交易状态查询交易：只有同步应答
|
||
|
||
```java
|
||
payOrder.setTransactionType(UnionTransactionType.QUERY);
|
||
Map<String, Object> params = service.query(null,"商户单号");
|
||
|
||
```
|
||
|
||
|
||
#### 退货交易：后台资金类交易，有同步应答和后台通知应答
|
||
|
||
```java
|
||
payOrder.setTransactionType(UnionTransactionType.REFUND);
|
||
Map<String, Object> params = service.refund("原交易查询流水号", "订单号", null,new BigDecimal("退款金额" ));
|
||
|
||
```
|
||
|
||
|
||
#### 文件传输类接口：后台获取对账文件交易，只有同步应答
|
||
|
||
```java
|
||
String fileConten = service.downloadbill("清算日期格式MMDD","文件类型，一般商户填写00即可");
|
||
```
|
||
