JDBC连接不到Mysql数据库

Question

使用JDBC的方法连接不上MySQL，想自己做个练习，然后就出现了一下的错误，希望各位哥哥姐姐帮忙看下！谢谢

Connection connection = null;
PreparedStatement preparedStatement = null;
ResultSet resultSet = null;
try
{
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8", "root", "user_xin");
}
catch (Exception e) {
e.printStackTrace();
if (resultSet != null) {
try {
resultSet.close();
}
catch (SQLException e1) {
e1.printStackTrace();
}
}
if (preparedStatement != null) {
try {
preparedStatement.close();
}
catch (SQLException e1) {
e1.printStackTrace();
}
}
if (connection != null)
try {
connection.close();
}
catch (SQLException e1) {
e1.printStackTrace();
}
}
finally
{
if (resultSet != null) {
try {
resultSet.close();
}
catch (SQLException e) {
e.printStackTrace();
}
}
if (preparedStatement != null) {
try {
preparedStatement.close();
}
catch (SQLException e) {
e.printStackTrace();
}
}
if (connection != null)
try {
connection.close();
}
catch (SQLException e) {
e.printStackTrace();
}
}

报错如下
