SpringApplicationContext (Power TAC server modules 1.7.0 API)

java.lang.Object
- org.powertac.common.spring.SpringApplicationContext

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware
```
@Service
public class SpringApplicationContext
extends Object
implements org.springframework.context.ApplicationContextAware
```
Static methods to access the Spring application context. It is set up as a service so Spring will create and initialize it. NOTE: These methods should NOT be used in constructors. Doing so makes it virtually impossible to test with mocks, and makes transitive dependencies very difficult in a test environment. Better to use them in individual "service getter" methods that do nothing for dependencies that have already been satisfied by test code using ReflectionTestUtils.setField(). ALSO NOTE: Even when used outside a constructor, there are still potential problems in a test environment, because if any test in a suite initializes Spring, then later tests that do not initialize Spring can retrieve instances from earlier tests, which may not be what the test expects. This can lead to baffling problems.
