尝试使用symfony运行查询,我收到此错误:

[Syntax Error] line 0, col 83: Error: Expected end of string, got 'username'

此代码抛出该错误:

$query = $em->createQuery(
            'SELECT username
            FROM BLOGBlogBundle:user
            WHERE username= :usrname'
        )->setParameter('usrname', $usr);
        $products = $query->getResult();

我究竟做错了什么？

尝试启动tomcat7时出现此错误：

我使用此链接：[ /sf/ask/556880971/?lq=1 ]并在我的JRE中复制“ tomcat-juli.jar”和...，但不起作用

ps：当我将tomcat 6更改为7时，出现此错误，我的项目在此更改之前有效！
