支付宝官方文档：https://opendocs.alipay.com/open/200/105311
开发者中心沙箱环境链接：https://openhome.alipay.com/platform/appDaily.htm?tab=info
按照文档上进行秘钥的生成和公钥的配置之后，引入支付宝的sdk 和freemarker
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.8.10.ALL</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
<version>2.2.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
支付参数类
public class AlipayVO {
/**
*商户订单号，需要保证不重复
*/
private String outTradeNo;
/**
*订单金额
*/
private String totalAmount;
/**
*订单标题
*/
private String subject;
/**
*订单描述
*/
private String body;
}
编写支付接口
@GetMapping("/alipay")
public void alipay(HttpServletRequest httpRequest,
HttpServletResponse httpResponse,AlipayVO alipayVO) throws ServletException, IOException {
AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.URL, AlipayConfig.APPID, AlipayConfig.RSA_PRIVATE_KEY, AlipayConfig.FORMAT, AlipayConfig.CHARSET, AlipayConfig.ALIPAY_PUBLIC_KEY, AlipayConfig.SIGNTYPE); //获得初始化的AlipayClient
AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();//创建API对应的request
alipayRequest.setReturnUrl(AlipayConfig.RETURN_URL);
alipayRequest.setNotifyUrl(AlipayConfig.NOTIFY_URL);//在公共参数中设置回跳和通知地址
Map<String, Object> map = new HashMap<>();
map.put("out_trade_no", alipayVO.getOutTradeNo());// 订单号
map.put("product_code", "FAST_INSTANT_TRADE_PAY");// 销售产品码
map.put("total_amount", alipayVO.getTotalAmount());// 交易金额,单位:元
map.put("subject", alipayVO.getSubject());// 订单标题
map.put("body", alipayVO.getBody());// 订单描述
alipayRequest.setBizContent(JSON.toJSONString(map));
String form = "";
try {
form = alipayClient.pageExecute(alipayRequest).getBody(); //调用SDK生成表单
} catch (AlipayApiException e) {
e.printStackTrace();
}
httpResponse.setContentType("text/html;charset=" + AlipayConfig.CHARSET);
httpResponse.getWriter().write(form);//直接将完整的表单html输出到页面
httpResponse.getWriter().flush();
httpResponse.getWriter().close();
}
编写个测试页面调用接口

编写进入模板的接口
@RequestMapping("/index")
public String index() {
return "indelx";
}
访问页面
