springboot集成支付宝沙箱支付
支付宝沙箱环境配置
首先进入支付宝开放平台的沙箱支付（如果没有支付宝开发平台账号的需要注册，需要相应的认证信息填写）点击进入沙箱环境用支付宝登录。
点击沙箱工具后进入沙箱管理界面
这里的应用公钥需要下载一个工具获取密钥工具下载，下载安装之后打开软件是这样的界面
点击生成密钥。会得到一对密钥分别是应用公钥和应用私钥，应用公钥是生成支付宝公钥必需的前置条件，应用私钥是我们后面springboot集成支付宝支付需要的
按照步骤把应用公钥复制到开放平台中得到支付宝公钥，这一步就不在赘述。
现在我们已经完成了沙箱环境的所有前置条件的获取，包括支付宝公钥，应用私钥，支付宝网关地址，appId，现在可以开始代码的编写了。
springboot 环境配置
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.35.79.ALL</version>
</dependency>在你的yml文件里面配置支付宝沙箱相关参数
alipay:
appId:
appPrivateKey:
alipayPublicKey:
notifyUrl: #如果是在本地测试需要下载内网穿透工具，用来支付宝的调的回调接口支付宝支付的相关配置代码AlipayConfig.java
@Component
@ConfigurationProperties(prefix = "alipay")
public class AliPayConfig {
private String appId;
private String appPrivateKey;
private String alipayPublicKey;
private String notifyUrl;
public String getAppId() {
return appId;
}
public void setAppId(String appId) {
this.appId = appId;
}
public String getAppPrivateKey() {
return appPrivateKey;
}
public void setAppPrivateKey(String appPrivateKey) {
this.appPrivateKey = appPrivateKey;
}
public String getAlipayPublicKey() {
return alipayPublicKey;
}
public void setAlipayPublicKey(String alipayPublicKey) {
this.alipayPublicKey = alipayPublicKey;
}
public String getNotifyUrl() {
return notifyUrl;
}
public void setNotifyUrl(String notifyUrl) {
this.notifyUrl = notifyUrl;
}
}添加相关的支付接口

recordService.updateById(record);

// 判断是否达到目标金额，如果达到则更新状态为已完成
if (donationProject.getCurrentAmount().compareTo(donationProject.getTargetAmount()) >= 0) {
donationProject.setStatus(1);
}
ordersService.updateById(donationProject);
}
}
}
/**
* 支付成功跳转前端页面接口
* @param request
* @param response

*/
@GetMapping("/redirect")
public void alipayRedirect(HttpServletRequest request, HttpServletResponse response) throws Exception {
// 添加缓存控制头
response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");
response.setHeader("Pragma", "no-cache");
response.setHeader("Expires", "0");
Map<String, String> params = new HashMap<>();
Map<String, String[]> requestParams = request.getParameterMap();
for (String name : requestParams.keySet()) {
params.put(name, request.getParameter(name));
}
boolean signVerified = checkAlipaySignature(params);
if (signVerified) {

private boolean checkAlipaySignature(Map<String, String> params) {

return AlipaySignature.rsa256CheckContent(
content,
sign,
aliPayConfig.getAlipayPublicKey(),
"UTF-8"
);
} catch (AlipayApiException e) {
e.printStackTrace();
return false;
}
}
}在你后端代码中的拦截器上忽略支付宝接口的配置
//允许直接访问的接口
.excludePathPatterns(
"/sysUser/login",
"/sysUser/register",
"/file/**",
//swagger放行
"/swagger-ui/**",
"/swagger-ui.html",
"/swagger-resources/**",
"/images/**",
"/webjars/**",
"/v2/api-docs",
"/configuration/ui",
"/configuration/security",
"/doc.html",
"/alipay/**" //重点别忘了
);如果是微服务项目，需要在网关处添加相应白名单，允许不鉴权。
按照上述配置之后，是可以成功进行沙箱支付。
希望本文对你进一步了解沙箱支付的相关逻辑有更大的帮助。
一入java深似海，争渡争渡！
