本地Java程序访问HTTPs遇到的问题

本地测试程序需要访问HTTPs,

String urlPath = "https://192.168.10.88/xxx/login?username=" + userName + "&password=" + password;
URL url = new URL(urlPath);
connection = (HttpURLConnection)url.openConnection();
connection.connect();

 

 抛出异常：

2. http://bluefoot.info/howtos/how-to-avoid-java-security-cert-certificateexception-no-name-matching-localhost-found/

 

在程序中添加

static {
        //for localhost testing only
        javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
        new javax.net.ssl.HostnameVerifier(){
            public boolean verify(String hostname,
                    javax.net.ssl.SSLSession sslSession) {
                if (hostname.equals("localhost")) {
                    return true;
                }
                return false;
            }
        });
    }

 抛出异常

 说明需要导入192.168.10.88的证书到本地%JAVA_HOME%/jre/lib/security/cacerts中

1. > keytool -import -file d:\https\server.crt -keystore "%JAVA_HOME%\jre\lib\security\cacerts" -alias 88server
2. java中cacerts证书库的默认密钥库密码是changeit
3. 再次验证是否成功导入：
4. > keytool -list -keystore "%JAVA_HOME%\jre\lib\security\cacerts" | findstr /i 88server

一切OK.
