连接Java - MySQL:不允许公钥检索

我尝试使用连接器8.0.11连接MySQL数据库与Java。一切似乎都很好，但我得到这个异常:

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.MysqlDataSource.getConnection(MysqlDataSource.java:119) at
     ConnectionManager.getConnection(ConnectionManager.java:28) at
     Main.main(Main.java:8)

下面是我的Connection Manager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();
    }
}

当前回答

使用jdbc url如下:

jdbc:mysql://localhost:3306/Database_dbName?allowPublicKeyRetrieval=true&useSSL=False;

PortNo: 3306在您的配置中可以不同

其他回答

将服务器时区设置为本地位置，修复了这个问题。

这也可能发生由于错误的用户名或密码。作为解决方案，我添加了allowPublicKeyRetrieval=true&useSSL=false部分，但我仍然得到了错误，然后我检查了密码，它是错误的。

我的问题是在pom.xml (spring boot)中。我的pom.xml有两个不同数据库的依赖项。确保只保留MySQL依赖项，并删除任何其他数据库依赖项。

spring.datasource.url=jdbc:mysql://localhost:3306/database?createDatabaseIfNotExist=true&allowPublicKeyRetrieval=true&useSSL=false

您可以将这一行插入到应用程序中。属性文件，这意味着，

spring.datasource.url=jdbc:mysql://localhost:3306/ This one uses mysql as the database service. I think this can changed by using relavent name and the port of your database name. database?createDatabaseIfNotExist=true = use the database named database if you haven't already make a database like that, make a new one. allowPublicKeyRetrieval=true = to allow the client to automatically request the public key from the server. (This part might be additional) useSSL=false = This will disable SSL and also suppress the SSL errors

此外，要警惕同一文件中的spring.jpa.database-platform=org.hibernate.dialect.MySQL8Dialect属性。

最后检查是否在pom.xml文件的dependencies中添加了以下依赖项。

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.23</version>
</dependency>

此解决方案适用于MacOS Sierra，并运行MySQL 8.0.11版本。请确保您在构建路径中添加了驱动程序-“添加外部jar”应该与SQL版本匹配。

String url = "jdbc:mysql://localhost:3306/syscharacterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true";
