带有gradle的Mysql jdbc ojdcn

Question

我有一个正在处理的纯Java项目，它正在使用gradle。我想连接到数据库（我的SQL）。

我应该在gradle构建文件中放什么？有人可以建议使用逐步解决方案吗？我只想查询数据库，问候

这是我的代码：

import java.sql.*;

    public class DBSupport {


       private  String url = "jdbc:mysql://10.90.256.15639.3306/guro";
       private String user = "jlkjhmhj";
       private String password = "jhgjkggh";


       public void getUserFromDB() throws ClassNotFoundException, IllegalAccessException, InstantiationException, SQLException {
           Class.forName("com.mysql.jdbc.Driver");
           Connection conn = DriverManager.getConnection(url, user, password);
           Statement stmt = conn.createStatement();
           ResultSet rowResult = stmt.executeQuery("select id from users where email = '[email protected]';`");
           String userId = rowResult.getString("id");
       }

这是我的例外

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

这是我的gradle构建文件
