方法详细资料

init

void init(Protocol<M> prot,
          PropertySet propertySet,
          ExceptionInterceptor exceptionInterceptor)

connect

void connect(ServerSession serverSession,
             String userName,
             String password,
             String database)

changeUser

void changeUser(ServerSession serverSession,
                String userName,
                String password,
                String database)

Re-authenticates as the given user and password

参数:

serverSession - ServerSession object

userName - user name

password - password

database - db name

getEncodingForHandshake

String getEncodingForHandshake()

getCharsetForHandshake

static byte getCharsetForHandshake(String enc,
                                   ServerVersion sv)

Get the MySQL collation index for the handshake packet. A single byte will be added to the packet corresponding to the collation index found for the requested Java encoding name. If the index is > 255 which may be valid at some point in the future, an exception will be thrown. At the time of this implementation the index cannot be > 255 and only the COM_CHANGE_USER rpc, not the handshake response, can handle a value > 255.

参数:

enc - The Java encoding name used to lookup the collation index

sv - server version

返回:

collation index
