java報錯--java.io.IOException: Server returned HTTP response code: 502

java.io.IOException: Server returned HTTP response code: 502 for URL: http://ip.taobao.com/service/getIpInfo.php?ip=219.xxx.xxx.xxx

通過淘寶ip庫獲取ip地址和地理位置報錯502

原因：淘寶獲取IP地址的接收，有時候會不穩定。(總的來說就是淘寶IP庫有時候會不穩定)

解決辦法：暫時沒時間找

暫時解決辦法：配置中關閉addressEnabled,addressEnabled=false，或者更換爲離線IP~
