Question

我正在运行此Java + SSL Tutorial，但我收到以下错误。

main, handling exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown
javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown
    at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source)
    at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown Source)

    at java.io.BufferedReader.readLine(Unknown Source)
    at java.io.BufferedReader.readLine(Unknown Source)
    at EchoServer.main(EchoServer.java:24)

发生异常的代码中的行是：

        while ((string = bufferedreader.readLine()) != null) {

我在这里做错了什么？自那个例子写完之后，事情发生了变化吗？

由于某种原因，您的证书可能无效（或未加载）。启用调试模式应该可以帮助您找到更多问题

System.setProperty（“javax.net.debug”，“all”）;

此外，如果您使用的是自签名证书，请查看：http://ctasada.blogspot.com.es/2010/11/httpclient-use-self-signed-certificates.html

运行简单SSL Java示例时出现SSLHandshakeException
