CachingSha2PasswordPlugin

public CachingSha2PasswordPlugin()

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.

参数:

prot - protocol instance

reset

public void reset()

从接口复制的说明: AuthenticationPlugin

Resets the authentication steps sequence.

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>

覆盖:

destroy 在类中 Sha256PasswordPlugin

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>

覆盖:

getProtocolPluginName 在类中 Sha256PasswordPlugin

返回:

plugin name

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>

覆盖:

nextAuthenticationStep 在类中 Sha256PasswordPlugin

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.

encryptPassword

protected byte[] encryptPassword()

覆盖:

encryptPassword 在类中 Sha256PasswordPlugin
