我尝试使用Connector8.0.11将mysql数据库与java连接起来。一切似乎都很好，但我有一个例外：
线程“main”java.sql.sqlnontransientconnectionexception中出现异常：不允许检索公钥
堆栈跟踪：

Exception in thread "main" java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:108) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:95) at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:122) at

连接器管理器：

public class ConnectionManager {

    public static final String serverTimeZone = "UTC";
    public static final String serverName = "localhost";
    public static final String databaseName ="biblioteka";
    public static final int portNumber = 3306;
    public static final String user = "anyroot";
    public static final String password = "anyroot";

    public static Connection getConnection() throws SQLException {

        MysqlDataSource dataSource = new MysqlDataSource();

        dataSource.setUseSSL( false );
        dataSource.setServerTimezone( serverTimeZone );
        dataSource.setServerName( serverName );
        dataSource.setDatabaseName( databaseName );
        dataSource.setPortNumber( portNumber );
        dataSource.setUser( user );
        dataSource.setPassword( password );

        return dataSource.getConnection();
    }
}
