两种方式 1.添加网站证书到密钥库 导入网站证书，并放入jdk1.7.0_51\jre\lib\security目录中 进入安装java所在目录,我的是如下的路径 C:\Program Files\Java\jdk1.7.0_51\jre\lib\security> 执行C:\Program Files\Java\jdk1.7.0_51\jre\lib\security>keytool -import -file zhaopin.cer -keystore cacerts -alias 别名 如果需要输入密码，默认为changeit 2.java类信任所有证书

调用httpclient之前执行 Protocol.registerProtocol("https", new Protocol("https", new MySSLSocketFactory(), 443)); 在httpclient模拟请求的时候，如果需要保留cookie,需要使用httpclient 提供的获取cookie的方法，不要自己从header中拿Set-Cookie头信息,以免无法正常模拟请求失败。
