用如下命令导入证书文件到jdk中去
keytool -import -alias 12306 -keystore cacerts -file D:\srca12306\srca.cer -trustcacerts
keytool -import -keystore %JAVA_HOME%\jre\lib\security\cacerts -file D:\srca12306\srca.cer -alias 12307
keytool -import -keystore cacerts -file D:\srca12306\srca.cer -alias 12307
jdk密钥库的默认密码为changeit
HttpsURLConnection 中文乱码问题

//编码问题,这边处理一下就ok了，不错 啊啊啊,对流进行转码

//怎么会这样，我的这个中文显示乱码，并且找不到这个中文字符
