处理无法连接到Mysql

Question

我一直在努力将处理草图连接到我的wamp服务器中的mysql，但是我遇到了sql错误，说明访问被拒绝

这是我的代码：

MySQL msql;


void setup()
{
    size( 100, 100 );
    String user     = "root";
    String pass     = "xxxx";

    String database = "test";

    msql = new MySQL( this, "localhost", database, user, pass );

    if ( msql.connect() )
    {
        msql.query( "SELECT COUNT(*) FROM temp" );
        msql.next();
        println( "number of rows: " + msql.getInt(1) );
    }
    else
    {
        // connection failed !
    }
}

void draw()
{
    //  visual sketch ...
}

我的用户名和密码与我的phpmyadmin以及mysql控制台一起工作正常。但在处理中我得到这个错误。

SQL.connect(): Could not connect to the database ( jdbc:mysql://localhost/test ).
