类 ConnectionUrlParser

  • 所有已实现的接口:
    DatabaseUrlContainer
    public class ConnectionUrlParser
extends Object
implements DatabaseUrlContainer
    This class parses a connection string using the general URI structure defined in RFC 3986. Instead of using a URI instance to ensure the correct syntax of the connection string, this implementation uses regular expressions which is faster but also less strict in terms of validations. This actually works better because database URLs don't exactly stick to the RFC 3986 rules.

    scheme://authority/path?query#fragment

    This results in splitting the connection string URL and processing its internal parts:

    scheme
    The protocol and subprotocol identification. Usually "jdbc:mysql:" or "mysqlx:".
    authority
    Contains information about the user credentials and/or the host and port information. Unlike its definition in the RFC 3986 specification, there can be multiple authority sections separated by a single comma (,) in a connection string. It is also possible to use an alternative syntax for the user and/or host identification, that also allows setting per host connection properties, in the form of "[user[:password]@]address=(key1=value)[(key2=value)]...[,address=(key3=value)[(key4=value)]...]...".
    path
    Corresponds to the database identification.
    query
    The connection properties, written as "propertyName1[=[propertyValue1]][&propertyName2[=[propertyValue2]]]..."
    fragment
    The fragment section is ignored in Connector/J connection strings.

        参数:
        userInfo - the string containing the user information
        返回:
        a ConnectionUrlParser.Pair containing the user and password information or null if the user information can't be parsed
