您可以通过代码连接云数据库RDS MySQL版的测试程序，示例代码如下。

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

public class mysqlconnection {

public static void main(String[] args) {

Connection conn = null;

String sql;

// 此处为您的连接地址、端口、账号、密码等信息。

String url = "jdbc:mysql://rdssoxxxxxxxxx.mysql.rds.aliyuncs.com:3306?zeroDateTimeBehavior=convertToNull&"

+ "user=michael&password=password&useUnicode=true&characterEncoding=UTF8";

try {

Class.forName("com.mysql.jdbc.Driver");

conn = DriverManager.getConnection(url);

Statement stmt = conn.createStatement();

//切换库。

String sqlusedb="use test_5";

int result1 = stmt.executeUpdate(sqlusedb);

//创建表。

sql = "create table teacher(NO char(20),name varchar(20),primary key(NO))";

int result = stmt.executeUpdate(sql);

//插入数据。

if (result != -1) {

sql = "insert into teacher(NO,name) values('2016001','wangsan')";

result = stmt.executeUpdate(sql);

sql = "insert into teacher(NO,name) values('2016002','zhaosi')";

result = stmt.executeUpdate(sql);

//查询数据。

sql = "select * from teacher";

ResultSet rs = stmt.executeQuery(sql);

System.out.println("学号\t姓名");

while (rs.next()) {

System.out

.println(rs.getString(1) + "\t" + rs.getString(2));

}

}

//捕捉异常。

} catch (SQLException e) {

System.out.println("MySQL操作错误");

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

conn.close();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

}
