替换证书，造成bad_certificate

系统调用外部的web service，走https方式，今天测试人员自己替换了https证书之后，说调用不通了，我协助定位了一下，在此记录一下定位过程，作为记录

查看cxf日志，发现以下错误信息：

感觉是证书的问题，于是从服务器上取下证书，用keytool -list -v 命令看了一下，配置的CN是正确的

但是比对了一下这个证书和原始证书的大小，发现不符合，显然不是同一份证书

因为对方的web service是双向认证https的，所以原先的证书信息，已经导入到对方的truststore里了。现在临时替换了一个证书，没有重新导入对方的truststore中，因此对方不接受新的证书，造成调用无法成功
