Hi @wwitt, I refer to your github project but I faced a problem when delegate task needs to @Autowired some service. May you please advise?

The setting of DemoConfiguration is same.

Error

> ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘testDelegate’: Unsatisfied dependency expressed through field ‘TestService’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.fifteenminuteflowable.demo.service.TestService’ available: expected at least 1 bean which qualifies as autowire candidate.

TestDelegate

```
package com.fifteenminuteflowable.demo.delegates;

@Component
public class TestDelegate implements JavaDelegate {
    @Autowired
    TestService testService;

    @Override
    public void execute(DelegateExecution delegateExecution) {
       testService.call();
    }
}

```
