Eclipse连接数据库的时候显示错误 找不到或无法加载主类 MyJDBC.Myjdbc

代码如下
package MyJDBC;

import java.sql.DriverManager;
import java.sql.SQLException;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;

public class Myjdbc {
public static void main(String args[]){
insert();
}
//连接数据库地址
public static String URL = "jdbc:mysql://localhost:3306/test";
public static String USERNAME = "root";
public static String PASSWORD = "09281010";
public static void insert(){
try {
// 1: 加载数据库驱动程序
Class.forName("com.mysql.jdbc.Driver");
//2： 获取数据库连接
try {
Connection conn = (Connection) DriverManager.getConnection(URL, USERNAME, PASSWORD);
//3：构造SQL语句
String sql = "insert into person(name,age,description)value('小白'，'18','一个猥琐的男人') ";
//4 ：构造一个statement 实例(用来发送SQL语句的载体)
Statement stat = (Statement) conn.createStatement();
//5 :执行SQL语句
stat.executeUpdate(sql);
//6: 关闭连接
stat.close();
conn.close();
System.out.println("success");
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
