远程给客户部署项目，运行时程序调外部接口时总是出不去，经过不懈努力，后来发现客户那边的网络走的是代理，于是在代码中加下面代码：

//设置代理  System.setProperty("http.proxySet", "true");  System.setProperty("http.proxyHost", "代理ip地址");  System.setProperty("http.proxyPort", "8080");

调试后，汗~~~不管用，又开始找资料，请教别人后才知道 只要在Tomcat的..\bin\catalina.bat文件里添加代理就可以了

找到set JAVA_OPTS加上如下代码即可：

set JAVA_OPTS=%JAVA_OPTS% -server -XX:PermSize=128M -XX:MaxPermSize=512m -Dhttp.proxyHost=代理服务器ip -Dhttp.proxyPort=代理服务器端口 -Dhttps.proxyHost=代理服务器ip -Dhttps.proxyPort=代理服务器端口

 心想这下应该可以正常运行了吧，结果还是超时，最后干脆用java的原始类HttpURLConnection替换掉第三方开源框架类HttpClient，运行后，OK ! ! ! ~

以下是部分代码：
