#### 一、前期准备 ####

*  进入[开放平台，沙箱环境][Link 1]，登录，一开始需要填写基本信息
 *  下载[支付宝开放平台开发助手][Link 2]，生成密钥需要用到  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQ0OTIyMTEz_size_16_color_FFFFFF_t_70 1]
 *  配置参数
    
     *  保留appId 和 支付宝网关，后面我们会用到

     *  生成密钥（打开我们下载的开发助手）， 保留公钥和私钥  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQ0OTIyMTEz_size_16_color_FFFFFF_t_70 3]
     *  将公钥配置到我们的沙箱环境中，保留最后的支付宝公钥，后面我们会用到

#### 二、项目应用 ####

1.  后台代码

*  编写 AlipayConfig.java 类，里面设计的参数，我们前一步都获取到了，填写到对应位置就可以了

/** * @author zte * @since 2021/1/28 15:10 */
    public class AlipayConfig { 
    
        /** * 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号 */
        public static String APP_ID = "";
    
        /** * 商户私钥，您的PKCS8格式RSA2私钥，这些就是我们刚才设置的 */
        public static String MERCHANT_PRIVATE_KEY = "";
    
        /** * 支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。，这些就是我们刚才设置的 */
        public static String ALIPAY_PUBLIC_KEY = "";
    
        /** * 异步通知，再这里我们设计自己的后台代码 */
        public static String notify_url = "https://www.baidu.com";
    
        /** * 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 */
        public static String return_url = "https://www.baidu.com";
    
        /** * 签名方式 */
        public static String SIGN_TYPE = "RSA2";
    
        /** * 字符编码格式 */
        public static String CHARSET = "utf-8";
    
        /** * 支付宝网关 */
        public static String GATEWAYURL = "";
    
        /** * 支付宝网关 */
        public static String LOG_PATH = "C:\\";
    
    
    //↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
    
        /** * 写日志，方便测试（看网站需求，也可以改成把记录存入数据库） * @param sWord 要写入日志里的文本内容 */
        public static void logResult(String sWord) { 
            FileWriter writer = null;
            try { 
                writer = new FileWriter(LOG_PATH + "alipay_log_" + System.currentTimeMillis()+".txt");
                writer.write(sWord);
            } catch (Exception e) { 
                e.printStackTrace();
            } finally { 
                if (writer != null) { 
                    try { 
                        writer.close();
                    } catch (IOException e) { 
                        e.printStackTrace();
                    }
