Can you run your unit tests without this "extra" .xml file?
Sometimes a different .xml file is created for unit testing.

I'm assuming you have an architecture like this: TodoController ==> TodoService ==> TodoDao.
If so, TodoController should handle all CRUD operations on your Todo entity.  Why would you have another controller that performs CRUD operations on the Todo entity?

If you DID have another controller that performed CRUD operations on the Todo entity, that controller could still use the TodoService and TodoDao layers; eliminating the need for duplicate code.

I get the feeling you are looking for a 'Spring-based' solution to your problem in order to learn Spring, but based on your requirements, a database trigger on the Todo table may be more appropriate.

I viewed your source code and was impressed.
Is this a tutorial you are following?
If so, would you share the link?

I forgot the braces on the getPrincipal function.....

model.addAttribute("user", userService.getUser(authentication.getPrincipal().getName()));

I'm guessing it's something in the UserController.
Line 11 looks suspicious; it doesn't return anything.
Try this:
comment out line 11
change line 12 to model.addAttribute("user", userService.getUser(authentication.getPrincipal.getName()));

Paul,

Here is a series of steps that will fix your problem:

1. Use a better naming convention; ie, stick to camel-case.  Rename your interfaces to: UserDao, UserService.
2. Even though you are autowiring UserDao twice, you still use the singleton instance created by the Spring container.
3. Remove @Qualifier annotation; it is not needed.
4. Remove line 41 from db-config.xml, since Component scanning will create this bean anyway.
5. In Web.xml remove lines 38-41.  You've already created a ContextLoaderListener in lines 20-23

Your closing head tag </head> needs to be as shown below.  Your code appears to have wrapped the body tags within the head tags, which is incorrect.

You need to use Maven to manage your .jar files.  It dramatically simplifies things.  
JavaBrains has some free tutorials on YouTube regarding using Maven with Spring.

Yes, you can mix.
In Spring MVC, I have used an .xml config file, while annotating components with @Controller, @Service and @Repository.
