Hi,
I get the following error when I try to run a Maven project in Spring. I am following a tutorial and I am using Java config instead of XML config. The following is the error message:

Error creating bean with name 'storeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.thestoreyardwebapp.service.ProductService com.thestoreyardwebapp.controllers.StoreController.productService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productDAO': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type Product!

I have gone over the tutorial for the past 2 days and think I need a fresh pair of eyes to have a look.
Thanks in advance,

That is entirely too much code for me to bother reading through unless someone was paying me to do it.

When publishing problems for help on the Ranch, please don't dump the entire source on us. Pare it down to the essentials. It may help you find the problem on your own and it will certainly help us to analyze it for you. If we need more, we'll let you know.

Having said that, here's some info on common causes of the problem.

First, make sure that the bean that you're attempting to autowire is itself being constructed. One thing I often run into is that a datasource bean that's injected into an entity manager bean that's auto-wired fails to construct due to bad/missing parameters (which in this case could even be that the database server didn't connect). If the upstream bean fails to construct, then the autowired bean cannot be constructed and therefore isn't available to be autowired into the target bean.

Secondly, make sure that the autowired property is properly defined. You have to have marked the property for auto-wiring, the property name must exactly match the name of the bean being wired in (including upper/lower case!) and you must have a public property setter method for that property that the wiring method can invoke in order to wire through.

Thanks Tim,
I'll try the suggestions, sorry for the overload.
