方法详细资料

init

public void init(Protocol<NativePacketPayload> prot)

从接口复制的说明: AuthenticationPlugin

We need direct Protocol reference because it isn't available from Connection before authentication complete.

指定者:

init 在接口中 AuthenticationPlugin<NativePacketPayload>

参数:

prot - protocol instance

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

reset

public void reset()

从接口复制的说明: AuthenticationPlugin

Resets the authentication steps sequence.

指定者:

reset 在接口中 AuthenticationPlugin<NativePacketPayload>

destroy

public void destroy()

从接口复制的说明: AuthenticationPlugin

Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed.

指定者:

destroy 在接口中 AuthenticationPlugin<NativePacketPayload>

getProtocolPluginName

public String getProtocolPluginName()

从接口复制的说明: AuthenticationPlugin

Returns the client-side name that the MySQL server uses on the wire for this plugin.

指定者:

getProtocolPluginName 在接口中 AuthenticationPlugin<NativePacketPayload>

返回:

plugin name

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

isReusable

public boolean isReusable()

指定者:

isReusable 在接口中 AuthenticationPlugin<NativePacketPayload>

返回:

true if plugin instance may be reused, false otherwise

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.
