Annotation Approach   ComponentScan    x y z    x y z dao

A delayed response but to give multiple packages using annotation based approach we can use as below    ComponentScan   com my package one   com my package subpackage two   com your package supersubpackage two

You can add multiple base packages  see axtavt s answer   but you can also filter what s scanned inside the base package    lt context component-scan base-package  x y z  gt      lt context include-filter type  regex  expression   service controller        gt   lt  context component-scan gt

If x y z is the common package then you can use    lt context component-scan base-package  x y z    gt    it will include all the package that is start with x y z like  x y z controller x y z service etc

lt context component-scan base-package  x y z   gt    will work since the rest of the packages are sub packages of  x y z   Thus  you dont need to mention each package individually

User · Answer

The following approach is correct    lt context component-scan base-package  x y z service  x y z controller    gt     Note that the error complains about x y z dao daoservice LoginDAO  which is not in the packages mentioned above  perhaps you forgot to add it    lt context component-scan base-package  x y z service  x y z controller  x y z dao    gt
