About Springmvc class not found [no qualifying bean of type [...] is defined] Issue

First of all, don't panic, this problem must be a certain configuration note is not written on:

Just a few places:

1. Whether the control layer adds @controller or whether the class that requires Pring management is added @component

Whether the 2.DAO layer adds @repository

If the 3.Service layer is added @service indeterminate case can @service ("Beanname") whether to refer to the DAO layer is not added @resource (I like to use @Resource annotation on the field, and this annotation belongs to the Java EE, The coupling with spring is reduced. The most important of these is that the code looks more elegant. )

4. Is whether the controller layer refers to @autowired

However, the fourth error message is not described in this heading, but is checked to see if the reference is also forgotten.
