We get more control over the handling and in particular the registration
of the endpoint this way. It was practically impossible to disable the
AgentServlet bean when in a parent context of the management server
because of lifecyce issues - you don't know that the user wants a
separate management server until too late.
This approach also makes it possible to test with spring-test MVC
support.
When management endpoints are on a different port the HandlerMappings
are restricted to a single EndpointHandlerMapping, so the error
controller (which is a normal @Controller with @RequestMappings) does
not get mapped.
Fixed by addinga shim Endpoint on "/error" that delegates to the
ErrorController (which interface picks up an extra method).
Remove '/resources/**' mapping since it can cause problems with the
'/**' when the developer defines their own 'resources' sub-folder.
Also remove default servlet config since the resources mapping renders
it redundant.
Issue: #55494446
The management endpoints were still all mixed up
with the user endpoints. Fixed that and extracted
user endpoints in to conditional block so not
protected if path explicitly set to empty string.
[#53029715]
* Add integration tests for /error view
* Add "error" @Bean as default view for HTML
Users may see side effects because now there will be
a ContentNegotiatingViewResolver by default for the
first time in a vanilla Actuator app. Should be
interesting.
