    • 方法详细资料

      • init

        public void init​(Protocol<NativePacketPayload> prot,
                 MysqlCallbackHandler cbh)
        从接口复制的说明: AuthenticationPlugin
        Initializes this plugin with a direct Protocol reference and a generic MysqlCallbackHandler that can be used to pass over information back to the authentication provider. For example an authentication plugin may accept null usernames and use that information to obtain them from some external source, such as the system login.
        指定者:
        init 在接口中 AuthenticationPlugin<NativePacketPayload>
        参数:
        prot - the protocol instance
        cbh - a callback handler to provide additional information to the authentication provider

      • requiresConfidentiality

        public boolean requiresConfidentiality()
        从接口复制的说明: AuthenticationPlugin
        Does this plugin require the connection itself to be confidential (i.e. tls/ssl)...Highly recommended to return "true" for plugins that return the credentials in the clear.
        指定者:
        requiresConfidentiality 在接口中 AuthenticationPlugin<NativePacketPayload>
        返回:
        true if secure connection is required

      • setAuthenticationParameters

        public void setAuthenticationParameters​(String user,
                                        String password)
        从接口复制的说明: AuthenticationPlugin
        This method called from Connector/J before first nextAuthenticationStep call. Values of user and password parameters are passed from those in NativeAuthenticationProvider#changeUser() or NativeAuthenticationProvider#connect(). Plugin should use these values instead of values from connection properties because parent method may be a changeUser call which saves user and password into connection only after successful handshake.
        指定者:
        setAuthenticationParameters 在接口中 AuthenticationPlugin<NativePacketPayload>
        参数:
        user - user name
        password - user password

      • nextAuthenticationStep

        public boolean nextAuthenticationStep​(NativePacketPayload fromServer,
                                      List<NativePacketPayload> toServer)
        从接口复制的说明: AuthenticationPlugin
        Process authentication handshake data from server and optionally produce data to be sent back to the server. The driver will keep calling this method on each new server packet arrival until either an Exception is thrown (authentication failure, please use appropriate SQLStates) or the number of exchange iterations exceeded max limit or an OK packet is sent by server indicating that the connection has been approved. If, on return from this method, toServer is a non-empty list of buffers, then these buffers will be sent to the server in the same order and without any reads in between them. If toServer is an empty list, no data will be sent to server, driver immediately reads the next packet from server. In case of errors the method should throw Exception.
        指定者:
        nextAuthenticationStep 在接口中 AuthenticationPlugin<NativePacketPayload>
        参数:
        fromServer - a buffer containing handshake data payload from server (can be empty).
        toServer - list of buffers with data to be sent to the server (the list can be empty, but buffers in the list should contain data).
        返回:
        return value is ignored.
