You should add mapping information for fields. Read more

Like this:

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

I made the mistake of adding a new Entity through console with a mapping type of 'php' instead of my default 'annotations'. Immediately without even touching the generated class my site wouldn't load. It threw this MappingException for my user class.

I removed the new Entity class thinking that would fix it, and everything else I could think of. Then I looked in my app/Resources/config directory. There was a new directory called Doctrine. It contained a mapping file for the Entity that caused the issue. When I removed this directory and file, the Exception was gone.

If you want to use annotations to defining your mapping, just select the option "annotations" when you generate your entity.

Although this question is quite old I don't want to keep a secret how I solved it. It seems that I had an old mapping files reference in the cache because I moved it to another folder. Clearing the cache solved the issue for me.
