创建config配置类
@Configuration
public class Config_alipay {
//创建支付宝所需要的对象
@Bean
public AlipayClient alipayClient(){
return new DefaultAlipayClient(AppUtil.gatewayUrl,AppUtil.app_id,AppUtil.merchant_private_key,"json",AppUtil.charset,
AppUtil.alipay_public_key,AppUtil.sign_type);
}
//支付信息的配置
@Bean
public AlipayTradePagePayRequest alipayTradePagePayRequest(){
return new AlipayTradePagePayRequest();
}
}
创建支付配置类
主要是公钥私钥以及appi等，还有异步通知以及页面跳转
public class AppUtil {

创建Controller
这里面的getnotify和getreturn只是用于反馈信息的，如果接入自己的业务,需要根据自己的实际业务需求进行重构。
@RestController
public class alipayController {
@Resource
private AlipayClient alipayClient;
@Resource
private AlipayTradePagePayRequest alipayTradePagePayRequest;
@RequestMapping("pay.api")
public String alipay1(String WIDout_trade_no, String WIDsubject, String WIDtotal_amount, String WIDbody){
System.out.println("pay");
//设置响应的地址(支付宝返回给商户的响应地址)
alipayTradePagePayRequest.setNotifyUrl(AppUtil.notify_url);
alipayTradePagePayRequest.setReturnUrl(AppUtil.return_url);
//4.设置请求的参数(传递给支付宝的数据)
alipayTradePagePayRequest.setBizContent(
"{\"out_trade_no\":\""+ WIDout_trade_no +"\","
+ "\"total_amount\":\""+ WIDtotal_amount +"\","
+ "\"subject\":\""+ WIDsubject +"\","
+ "\"body\":\""+ WIDbody +"\","
+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
//发送请求
String result = null;
try {
result = alipayClient.pageExecute(alipayTradePagePayRequest).getBody();
} catch (AlipayApiException e) {
e.printStackTrace();
}
return result;
}
/**
* 接收支付宝返回的异步通知的信息
* @param request
* @return
*/
@RequestMapping("getnotify")
public String getnotify(HttpServletRequest request){
//商户订单号
String out_trade_no =request.getParameter("out_trade_no");
//支付宝交易号
String trade_no = request.getParameter("trade_no");
//交易状态
String trade_status = request.getParameter("trade_status");
StringBuffer sb = new StringBuffer();
sb.append("接收支付宝返回的异步通知的信息=");
sb.append("商户订单号:");
sb.append(out_trade_no);
sb.append("支付宝交易号:");
sb.append(trade_no);
sb.append("交易状态:");
sb.append(trade_status);
System.out.println(sb);
return sb.toString();
}
/**
* 获取支付宝GET过来反馈信息
* @param request
* @return
*/
@RequestMapping("getreturn")
public String getreturn(HttpServletRequest request){
//商户订单号
String out_trade_no =request.getParameter("out_trade_no");
//支付宝交易号
String trade_no = request.getParameter("trade_no");
//交易状态
String total_amount = request.getParameter("total_amount");
StringBuffer sb = new StringBuffer();
sb.append("获取支付宝GET过来反馈信息=");
sb.append("商户订单号:");
sb.append(out_trade_no);
sb.append("支付宝交易号:");
sb.append(trade_no);
sb.append("交易金额:");
sb.append(total_amount);
return sb.toString();
}
}
编写前端页面
然后需要一个前端html页面调用这个api
<html>

然后就可以通过支付宝进行付款操作了 ，非常的方便,非常的银杏。
