连接Java-MySql:不允许公钥检索 [英] Connection Java-MySql : Public Key Retrieval is not allowed
问题描述
我尝试使用连接器8.0.11将MySql数据库与Java连接.一切似乎都还可以,但是我有一个例外:
I try to connect MySql database with Java using connector 8.0.11. Everything seems to be ok but I have this exception:
线程"main"中的异常java.sql.SQLNonTransientConnectionException:不允许公钥检索
Exception in thread "main" java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed
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();
}
}
推荐答案
您应在mysql-connector allowPublicKeyRetrieval=true
中添加客户端选项,以允许客户端自动从服务器请求公钥.请注意,AllowPublicKeyRetrieval=True
可能允许恶意代理执行MITM攻击以获取纯文本密码,因此默认情况下为False,必须显式启用它.
You should add client option to your mysql-connector allowPublicKeyRetrieval=true
to allow the client to automatically request the public key from the server. Note that AllowPublicKeyRetrieval=True
could allow a malicious proxy to perform a MITM attack to get the plaintext password, so it is False by default and must be explicitly enabled.
https://mysql-net.github.io/MySqlConnector/connection-options /
您也可以在将useSSL=false
用于测试/开发目的时尝试添加
you could also try adding useSSL=false
when you use it for testing/develop purposes
示例:
jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&useSSL=false
