java - Simplify DAO Layer with Resteasy / Hibernate / Spring -

i'm looking cleaner code dao layer :

i have generic dao interface :

public interface genericdao<t> {     t save(t entity);     t merge(t entity);     void delete(t entity);     t findfromid(int id);     list<t> findall(); } 

an abstract implementation :

public abstract class abstractgenericdaoimpl<t> implements genericdao<t> {     [...] } 

for each database entity, have 2 files :

an interface :

public interface userdao extends genericdao<userpe> {  } 

a concrete class :

@repository public class userdaoimpl extends abstractgenericdaoimpl<userpe> implements userdao {      [ no code entities ]  } 

i'm using spring injection :

@autowired private userdao userdao; 

i'd use generic dao common entities, :

@autowired private genericdao<myentity> myentitydao; 

but spring doesn't want inject (nosuchbeandefinitionexception) , don't know how configure hibernate queries (which needs entity classes).

i'm using : spring 3.1.0 hibernate 3.6.3 resteasy 2.3.7

do have idea ?

thks reading.

if use spring 4, able use

@autowired private genericdao<myentity> myentitydao; 

if there implementation of genericdao without doing else.

such capability missing in spring 3. check out this blog post more details.

however, if introduce spring 4 project might break integration resteasy. that's you'll need check.
