一、前言
已有教程大部分是使用jdk自带keytool生成自签名证书，自己测试可以的，但是用于实际使用时，在ssl双向认证中服务器认证客户端时，不可避免的每增加一个客户，服务器端需要添加信任列表。
解决方法：使用同一ca(向第三方机构申请或者自己模拟一个)签名过的服务器和若干客户端，服务器只需要添加该ca的信任认证即可。
二、工具链接（推荐openssl）

三 补充
1 p12转jks
1
keytool -importkeystore -srckeystore server.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore server.jks
2 导入信任cer到jks
1
keytool -import -v -alias root -file root.cer -keystore server.jks
3 server.jks 应包含 server的秘钥，信任的root的公钥
4 浏览器里应该有的证书：root的包含公钥的证书（一般cer格式导入），由root签发的各个用户的含有秘钥的证书（一般p12格式导入）
5 应用服务器server.xml 一般配置
