如何在 Java 中连接到 MySQL 数据库？

当我尝试时，我得到

java.sql.SQLException: No suitable driver found for jdbc:mysql://database/table
    at java.sql.DriverManager.getConnection(DriverManager.java:689)
    at java.sql.DriverManager.getConnection(DriverManager.java:247)

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

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

最佳答案

DriverManager是一种相当古老的做事方式。更好的方法是获取 DataSource ，或者通过查找您的应用服务器容器已经为您配置:

Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("java:comp/env/jdbc/myDB");

MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setUser("scott");
dataSource.setPassword("tiger");
dataSource.setServerName("myDBHost.example.org");

Connection conn = dataSource.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT ID FROM USERS");
...
rs.close();
stmt.close();
conn.close();
