I'm a little confused as to how the IOC works in spring. Say I have a service class called UserServiceImpl that implements UserService interface. How would this be auto-wired?

I have a Java class (Entity) with a set of named queries. When the Spring tries to inject the related bean, it is not finding one of the queries.

I want to make all beans request scoped by default, however the Spring documentation says that the default scope is Singleton. (sections 3.4.1 and 3.4.2 http://static.springsource.org/spring/docs/2.5.x/reference/beans.html) I want to declare the default scope to be request scoped. This is the closest thing I have found so far -- it's ...
Little confused, the basic spring mvc app has this: app-config.xml <context:component-scan base-package="org.springframework.samples.mvc.basic" /> and the mvc-config.xml has: <!-- Configures the @Controller programming model --> <mvc:annotation-driven /> Do you really need both? for component-scan, does this mean if I don't p...

I am setting up a simple RESTful controller for a Todo resource with an XML representation. It all works great - until I try to redirect. For example, when I POST a new Todo and attempt to redirect to its new URL (for example /todos/5, I get the following error: Error 500 Unable to locate object to be marshalled in model: {} I do know...
In my Spring MVC based web-app, I'm manually creating an Errors/BindingResult object after manually validating one of my domain objects.

It’s a general consensus that Singleton is bad for unit-testing. But what about having an IoC container like the Spring framework to control your beans which are singletons by default? Is using those beans in your classes also considered bad for unit testing the same way singleton is? ...

I am getting this exception in a controller of a web application based on spring framework using hibernate. I have tried many ways to counter this but could not resolve it. In the controller's method, handleRequestInternal, there are calls made to the database mainly for 'read', unless its a submit action. I have been using, Spring's S...

I am using Spring with WebSphere 6.1 and today I started to get NET_BIND errors stating that port 1099 (port that Spring is using) is already in use and that Spring cannot use it. I've been using that port for a long time and ran netat to make sure that 1099 wasn't listed (which it wasn't). I also looked at the ports configured for my ...
I am wiring my UserService type classes using spring's IOC. But what about my User class? I have a interface User, then a UserImpl class. In my controller action's do I just do: User u = new UserImpl(); Or would it sometimes make sense to use IOC for this also? Sometimes I use a different constructor also when instantiating a cla...
