Harmonize the configuration properties for Undertow to match the changes
made for gh-2491.
Move `spring.undertow.accessLog*` to `spring.undertow.accesslog.*`
- Apply project’s code formatting and conventions
- Don’t use the IO and worker thread configuration when creating the
worker for the AccessLogReceiver. The IO and worker thread
configuration is for HTTP request processing and a worker in its
default configuration should be sufficient for the access log
receiver.
- Don’t use a temporary directory as the default for the access log
directory. A temporary directory makes (some) sense for Tomcat as it
requires a directory for its basedir. Undertow has no such
requirement and using a temporary directory makes it hard to locate
the logs. The default has been updated to a directory named logs,
created in the current working directory.
- Document the new properties in the application properties appendix
Closes gh-3014
Undertow, like Tomcat, uses "" for the context path of the root
context. Previously, the Undertow deployment was being configured with
"/" for the root context. This was leading to a silent failure in
AsyncContextImpl.dispatch when it failed to look up the deployment
manager for the current request.
This commit updates UndertowEmbeddedServletContainerFactory to use the
correct context path (an empty String) for the root context.
Fixes gh-2365
