我正在使用java连接到db。

Class.forName("org.drizzle.jdbc.DrizzleDriver");

Connection connection = DriverManager.getConnection(""jdbc:drizzle://" + ADDRESS + ":" + PORT + "/" + DB", userName, password);

Connection connection = DriverManager.getConnection(
                        "jdbc:drizzle://" + DBProperties.ADDRESS + ":" + DBProperties.PORT + "/?allowMultiQueries=true",
                        DBProperties.USER, DBProperties.PASS)

<dependency>
        <groupId>org.drizzle.jdbc</groupId>
        <artifactId>drizzle-jdbc</artifactId>
        <version>1.4</version>
    </dependency>

我不知道为什么我能得到这个能有人帮助我吗？

请尝试按照https://mariadb.com/kb/en/library/about-mariadb-connector-j/

中的建议操作

我会从您的maven依赖项中删除drizzle驱动程序并包含最新版本的mariaDB连接器

<dependency>
    <groupId>org.mariadb.jdbc</groupId>
    <artifactId>mariadb-java-client</artifactId>
    <version>2.2.3</version>
</dependency>

然后我会替换官方示例的客户端代码：

Connection connection = DriverManager.getConnection("jdbc:mariadb://localhost:3306/DB?user=foo&password=bar");

使用适当的端口，用户等值。我希望你发现它很有用

无法创建连接：无法连接：客户端不支持服务器请求的身份验证协议
