## 微信支付简单例子

#### 支付配置

```java

        WxPayConfigStorage wxPayConfigStorage = new WxPayConfigStorage();
        wxPayConfigStorage.setMchId("合作者id（商户号）");
        wxPayConfigStorage.setAppid("应用id");
        wxPayConfigStorage.setKeyPublic("密钥");
        wxPayConfigStorage.setKeyPrivate("密钥");
        wxPayConfigStorage.setNotifyUrl("异步回调地址");
        wxPayConfigStorage.setReturnUrl("同步回调地址");
        wxPayConfigStorage.setSignType("签名方式");
        wxPayConfigStorage.setInputCharset("utf-8");
        //是否为测试账号，沙箱环境 此处暂未实现
        wxPayConfigStorage.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 

        //支付服务
        PayService service =  new WxPayService(wxPayConfigStorage);
        
        //设置网络请求配置根据需求进行设置
        //service.setRequestTemplateConfigStorage(httpConfigStorage)

```

#### 创建支付订单信息

```java

        //支付订单基础信息
           PayOrder payOrder = new PayOrder("订单title", "摘要",  new BigDecimal(0.01) , UUID.randomUUID().toString().replace("-", ""));
  
``` 

#### 扫码付

```java

 
            /*-----------扫码付-------------------*/
           payOrder.setTransactionType(WxTransactionType.NATIVE);
           //获取扫码付的二维码
           BufferedImage image = service.genQrPay(payOrder);
           /*-----------/扫码付-------------------*/


``` 

#### APP支付

```java

        /*-----------APP-------------------*/
          payOrder.setTransactionType(WxTransactionType.APP);
              //获取APP支付所需的信息组，直接给app端就可使用
          Map appOrderInfo = service.orderInfo(payOrder);
        /*-----------/APP-------------------*/

``` 

#### 网页支付

```java

        /*-----------网页支付-------------------*/

        payOrder.setTransactionType(WxTransactionType.MWEB); //  网页支付
        //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);
        /*-----------/即时到帐 WAP 网页支付-------------------*/

``` 

#### 条码付 刷卡付

```java

        /*-----------条码付 刷卡付-------------------*/
        payOrder.setTransactionType(WxTransactionType.MICROPAY);//条码付
        payOrder.setAuthCode("条码信息");
        // 支付结果
        Map params = service.microPay(payOrder);

```java

        /*-----------回调处理-------------------*/
        //HttpServletRequest request;
         Map<String, Object> params = service.getParameter2Map(request.getParameterMap(), request.getInputStream());
        if (service.verify(params)){
            System.out.println("支付成功");
            return;
