连接 Java - MySQL:不允许检索公钥
我尝试使用连接器8.0.11将MySQL数据库与Java连接。一切似乎都还好,但我得到这个例外:
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.MysqlDataSource.getConnection(MysqlDataSource.java:119) at
ConnectionManager.getConnection(ConnectionManager.java:28) at
Main.main(Main.java:8)
这是我的连接管理器类:
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();
}
}
