SimpleDiscoveryClientAutoConfiguration doesn't use SimpleDiscoveryProperties bean, but direct method call

[lightoze]

When I attempt to use service discovery from BeanPostProcessor, SimpleDiscoveryClient returns empty instance list. Example code would be:

applicationContext.getBean(CompositeDiscoveryClient.class).getInstances("oidc-server")

While debugging I can see that SimpleDiscoveryClient#getInstances is called before SimpleDiscoveryProperties#init, and during that first call properties are not yet initialized and instance list is empty.

Root cause seems to be SimpleDiscoveryClientAutoConfiguration and proxyBeanMethods = false. Should be trivial to fix with explicit method argument injection.

SimpleDiscoveryProperties#init is a bean lifecycle method that is only called after the bean is properly constructed. Using it in a BeanPostProcessor is simply too early.

I'm using postProcessAfterInitialization which is called after lifecycle methods. The problem is SimpleDiscoveryClientAutoConfiguration directly calling own @Bean method while proxying is disabled.

right, looks like 18a4227 broke this.
