The Spring Container Lifecycle

The Spring Container Lifecycle

When you mount an application context, Spring starts up, following a predictable lifecycle. The actions it performs are:

1. Load all bean definitions before constructing beans
2. Construct each bean via reflection
3. Inject components via setters, autowired methods, etc...
4. Post-process the bean
5. Make the bean available for use by injection or direct lookup

Obviously we're going to focus on that post-processing step. It turns out Post Processing allows Spring's magic to happen.
