Java SSL：客户端握手失败，服务器没有常见的密码套件

1 周，3 日 Questions & Answers 308

我正在尝试通过Java中的SSLsocket从客户端连接到服务器。客户端接收握手失败，服务器端（www）没有通用的密码套件

服务器配置为SSL Tomcat 9，以下是连接器：

        <Connector SSLEnabled="true" acceptCount="100" clientAuth="false"
            disableUploadTimeout="true" enableLookups="false" maxThreads="25"
            port="8443" keystoreFile="C:/Users/xxx/.keystore" keystorePass="xxx"
            keystoreType="PKCS12"
            protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https"
            secure="true" sslProtocol="TLS" />

客户端是Java项目。双方都有钥匙工具证书。证书已从keytool导出，并由keytool在客户端导入。所以，在客户端和服务器端，我们导入了服务器。cer。 Tomcat从端口8443启动，socket使用端口443

我试过什么？ -在代码中设置协议 -设置密码套件 -更换端口 -从8080和8443端口启动tomcat

服务器：

    void mySSLServerSocket(int port) throws IOException {

        SSLServerSocketFactory sslServerSocketFactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
        SSLServerSocket sslServerSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(port);
        sslServerSocket.setEnabledProtocols(new String[] {"TLSv1.2"});
        sslServerSocket.setEnabledCipherSuites(new String[] {"TLS_RSA_WITH_AES_256_CBC_SHA"});
        SSLSocket socket = (SSLSocket) sslServerSocket.accept();
        OutputStream out = socket.getOutputStream();
        InputStream in = socket.getInputStream();
        while(true) {
            int orderNumber = in.read();
            System.out.println("order number readed: " + orderNumber);
        }
    }

客户：

    void mySocket(String ip, int port) throws IOException {

        SSLSocketFactory sslSocketFactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
        SSLSocket sslSocket = (SSLSocket) sslSocketFactory.createSocket(ip, port);
        sslSocket.setEnabledProtocols(new String[] {"TLSv1.2"});
        sslSocket.setEnabledCipherSuites( new String[] {"TLS_RSA_WITH_AES_256_CBC_SHA"});
        sslSocket.startHandshake();
        InputStream in = sslSocket.getInputStream();
        OutputStream out = sslSocket.getOutputStream();
        out.write(1);
        while (in.available() > 0) {
            System.out.print(in.read());
        }

    }

客户端错误：

错误表明没有密码套件，但我检查了支持的密码并选择了一个，对双方都可用。声明了TSL协议，但仍然没有成功

我想成功地从客户端连接到服务器，但不知道下一步该怎么做，因为在internet上找不到任何建议

我读过一些关于连接所需的私钥的内容。它在哪里？我猜，那个服务器。cer只有公钥

当tomcat在8443上运行时，使用端口443作为socket是否合适？也许我应该在某个地方指定那些端口

有 Java 编程相关的问题?
