注意：一定要使用httpclient-4.3.5.jar，httpcore-4.3.2.jar。如果使用的话，每次调用的时候提示握手失败；

可以使用：httpclient-4.3.6.jar，httpcore-4.3.6.jar 本实例就是使用了这个版本。


Tomcat 版本配置SSL过程有两步
1用JDK自带的keytool.exe来生成私有密钥和自签发的证书，如下：
keytool -genkey -keyalg RSA -alias tomcat

2修改Tomcat的conf\server.xml文件，即增加下面一段

tomcat6 在server.xml

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" 
  keystroke="${user.home}/.keystore"  keystorePass="changeit"  />

tomcat7

  <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
   keystoreFile="${user.home}/.keystore"  keystorePass="changeit"
               clientAuth="false" sslProtocol="TLS" />


keystoreFile：证书存放位置
keystorePass：证书密码
