上面说了一大堆，没一个说到点子上。
1. 你访问的域名要与 要与 subject name 一样; (可以是IP)

2. 你要有（你访问网站）的跟证书.假设为ca.cer, 然后导入到名称为ca的keystore中(假设)
3.客户端需要制定trustStore, 如加入以下代码
System.setProperty("javax.net.ssl.trustStore", "c:\ca");
或是:
加入默认信任密钥库:keytool -import -keystore C:\Java\jdk1.6.0_14\jre\lib\security\cacerts -storepass changeit -file ca.cer -alias ca
这样就可以了.
还有, 我们之所以访问一些https网站，没有弹出错误提示,那是因为我们浏览器上有哪些网站的根证书.如:versign.cer,所以你用代码访问https网站，也是一样.

前天 刚学会使用httpclient访问https网站 不过我用的是httpclient 4的版本 ，楼主貌似是老版本的了...基本上处理流程如下 第一条最重要[Quote=引用 7 楼 swoky 的回复:]

1,证书的域名跟你程序中的域名一样(这个重要)
e.g.
keytool ...... -dname "CN=xxxx.com, OU=.........."

2,jdk中证书正确(你的getKeyStore方法没试过,一直是导入jdk的)

3,sun jdk中的https连接只能用域名的,不能用IP(配hosts也OK)

Exception in thread "main" javax.net.ssl.SSLException: hostname in certificate didn't match: <eps.dev.surepush.cn> != <*.xxxxxxx(公司名称).com>
程序中你访问的是
https://eps.dev.surepush.cn:443/epscu/
证书中的hostname是<*.xxxxxxx(公司名称).com>
二者不匹配，所以出异常了
你得先把二者搞匹配才行
把<*.xxxxxxx(公司名称).com>
映射到eps.dev.surepush.cn对应的IP可以尝试下

测试类2：


public static void main(String[] args) throws Exception {

		

		ZTest test = new ZTest();

大概意思我也能看懂，第一个异常是路径不匹配，我按照网上查找的方法，修改Windows\System32\drivers\etc\的文件夹，也改不对。
第二个异常不能识别证书，我按照https的路径，导了N次还是不对。
但问题就是没解决，郁闷死了，高人指点一下。。
我要解决办法啊啊啊。。。
当你在代码里遇到HTTP 403错误时，这些方法能救你一命！（超详细排坑指南）
解决403错误就像和服务器玩捉迷藏，核心思路就是让自己的请求看起来像"正常...如果所有方法都试过还是不行…可能是时候联系网站管理员跪求API权限了（认真脸）。遇到其他奇葩情况欢迎在评论区留言，咱们一起见招拆招！
