支付寶沙箱demo運行出現read timed out的解決辦法

問題描述

博主在使用支付寶沙箱集成當面付接口時，遇到一個問題。原本按照按照官方的解釋，本身下載完demo之後，修改裏面的部分參數：

# 支付寶網關名、partnerId和appId
open_api_domain = https://openapi.alipaydev.com/gateway.do
mcloud_api_domain = http://mcloudmonitor.com/gateway.do
pid = ?
appid = ？

# RSA私鑰、公鑰和支付寶公鑰
private_key =？
public_key =？

#SHA1withRsa對應支付寶公鑰，已經廢棄
#alipay_public_key = MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDDI6d306Q8fIfCOaTXyiUeJHkrIvYISRcc73s3vF1ZT7XN8RNPwJxo8pWaJMmvyTn9N4HQ632qJBVHf8sxHi/fEsraprwCtzvzQETrNRwVxLO5jVmRGi60j8Ue1efIlzPXV9je9mkjzOmdssymZkh2QhUrCmZYI/FCEa3/cNMW0QIDAQAB

#SHA256withRsa對應支付寶公鑰
alipay_public_key =？

# 簽名類型: RSA->SHA1withRsa,RSA2->SHA256withRsa
sign_type = RSA2
# 當面付最大查詢次數和查詢間隔（毫秒）
max_query_retry = 5
query_duration = 5000

# 當面付最大撤銷次數和撤銷間隔（毫秒）
max_cancel_retry = 3
cancel_duration = 2000

# 交易保障線程第一次調度延遲和調度間隔（秒）
heartbeat_delay = 5
heartbeat_duration = 900

也就是5個問號，而後運行主方法就應該能夠獲得正確的代碼：

可是實際運行的結果則是：

問題解決

這個問題真是干擾了好久，去支付寶論壇發現也沒有解決的辦法，後來才發現是由於支付寶目前還不支持java10，而我用的就是java10.若是你改用java7,8就不會出現這種問題了。其實關於付寶目前還不支持java10這個，好像官方人員都沒有一個合理的說明，反正你用java10就是不行，運行不了，用java7,8就是能夠。
