We now have a much simpler DataSourceAutoConfiguration that binds to whatever
DataSource concrete type it finds at runtime. To be able to quickly switch between
Hikari and the other types of DataSource there's a minute shim for translating
the common properties (username, password, url, driverClassName), but actually
only url is different. The shim and also DataSource initialization is supported
through DataSourceProperties, but the other native properties get bound directly
through the concrete runtime type of the DataSource.
The /configprops endpoint works (and is exposed in the actuator sample).
Fixes gh-840, fixes gh-477, see also gh-808.
Usage:
$ gradle bootRun
...
Edit files in src/main/resources and see the changes live in a web app
(e.g. static resources in /static).
The old functionality of bootRun has been replaced (since it didn't add
a lot of value and also didn't expose any JMV argument setters of anything).
This new feature set is backed by any existing "run" task configuration.
In addition autodetects a main class if there is one in the project
sources, so no need for mainClassName = '...' in build.gradle.
Applies the 'application' plugin (so no need to declare that either).
Fixes gh-225
