Spring NPE using Annotations

Question

So I am having a problem that I know is something stupid that I am forgetting to do. I've used Spring before but using the XML method. But for this I have to use the annotations, the JSR 330 annotations (I have this dependency in my pom.xml).

What I have so far is:

ExampleService.java

package com.example.service.workflow;

@Named
public class ExampleService
{
    @Inject
    private StartService startService;

    ...
}

StartService.java

package com.example.service.workflow;

@Named
public class StartService
{
    ...
    public SvcStatus execute(...)
    {
        ...
    }
}

and then I have this in my sprint-context.xml:

<context:component-scan base-package="com.example.service.workflow" />

However, when I run my program, I am getting a NullPointerException on the startService object, when I try to call the execute() method.

It is not set in stone that I use the JSR 330 annotations. I know that the problem is probably around my use of the @Named annotation, but I have also tried different permutations of @Component, @Service and @Controller.

Using Spring version 4.2.3. Using modules spring-beans and spring-context, and spring-core. I've also tried with all of the spring modules included.

Show us a complete example. Show us how you attempt to call `execute`. How do you retrieve the `ExampleService` bean? — Sotirios Delimanolis, Dec 09 '15 at 15:25
I've updated my question with the relevant information. And, yes I am calling new ExampleService(), so I guess this is probably where I am going wrong? — MeanwhileInHell, Dec 09 '15 at 15:30
yes, that's it ... in order to let spring "do his work", you should call `new Something()` on any spring bean ... — Pras, Dec 09 '15 at 15:35
