我是靠谱客的博主大胆橘子，最近开发中收集的这篇文章主要介绍2020-8-11 springboot项目接入支付宝接口，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

不会的时候觉得项目接入支付宝接口男上加男，学会以后觉得还是挺简单的（狗头），总结一下步骤：

1、登录支付宝开放平台，手机支付宝扫一扫也就登录了，真方便

2、进入沙箱环境，在RSA2秘钥的地方可以生成秘钥，需要下载，我的已经生成过了

这两处地方可以和我配置的一样，回调地址是支付宝付款成功后跳转的地址

3、下载SDK

点我，

大概这个样子吧

<!-- alipay -->
    <dependency>
      <groupId>com.alipay.sdk</groupId>
      <artifactId>alipay-sdk-java</artifactId>
      <version>3.1.0</version>
    </dependency>

4、又是工具类

工具类基本上是这样的，和微信比，接入支付宝真是简单多了，接口文档写的也很好，爱了爱了。这个返回的form其实是一个前端的form表单，会自动提交，可以在控制台输出看一下效果，但是最后的<script>标签在前端的时候会自动解析，所以可以截取下来，将form放入前端的div中，通过jquery选择器获取到form,.submit()提交就可以了。支付宝做的这个页面在支付完成后会自动跳转到我们制定的页面。接入就完成了。

package com.fh.util;

import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.request.AlipayTradePagePayRequest;
import com.fh.entity.Order;

import javax.servlet.http.HttpServletRequest;
import java.io.IOException;

public class AliPayUtil {

    public static String payController(HttpServletRequest request, Order order) throws IOException {
        //获得初始化的AlipayClient
        AlipayClient alipayClient = new DefaultAlipayClient(
