Java SSL HTTPS进行双重认证开发实践

1、我们先将.cer 和.jks文件导出然后发给服务端进行证书认证才好进行接下来的开发
      1.1、至于如何导出：
      命令1.keytool -genkeypair -dname "cn=clientAuth_PhevBattery, ou=IS, o=SGM, c=CN" -alias clientAuthCert -keypass Pass1234 -keystore d:\clientAuth_PhevBattery.jks -storepass Pass1234 -validity 3600  -keyalg RSA -keysize 2048 -sigalg SHA256WithRSA
      命令2：keytool -export -file d:\clientAuth_PhevBattery.cer -keystore d:\clientAuth_PhevBattery.jks -storepass Pass1234 -alias clientAuthCert
       PS：.cer是我们的证书保存了公钥，.jks保存的公钥和秘钥的算法  个人理解，如果错了希望大家可以提供改正，谢谢
    2、开发过程中遇到两个问题
       1.1、没搞明白JDK的security/cacerts库的是什么意思
            经查询资料显示cacerts是一个秘钥库，我们在执行SSL认证的时候会使用到
       1.2、客户没有将我们导出的.cer证书成功的加入到秘钥库进行受信任，所以在测试的过程中程序报错
