This commit replaces Spring Boot's basic dependency management support
with separate dependency management plugin. This has a number of
benefits including:
1. A Maven bom can be used rather than a custom properties file
2. Dependency management is applied transitively rather than only to
direct dependencies
3. Exclusions are applied as they would be in Maven
4. Gradle-generated poms are automatically configured with the
appropriate dependency management
Closes gh-2133
By default, SnakeYAML will convert a timestamp-like string into a
java.util.Date. This differs to properties file-based configuration
where the values are always strings. Dates are problematic as the
round trip (string -> Date -> string) can change the value. For example,
“2015-01-27” becomes “Tue Jan 27 00:00:00 GMT 2015”.
This commit updates YamlPropertySourceLoader to use a Yaml with a
custom Resolver subclass that suppresses the addition of the implicit
resolver for timestamps. Supressing the addition of the unwanted
resolver, rather than overriding addImplicitResolvers and registering
the resolvers that we do want, ensures that we get all of the other
default Resolvers in their default order.
Fixes gh-2422
This commit adds support for configuring Log4j 2 with YAML. It also
improves the existing support for configuring Log4j 2 with JSON.
Previously, Log4J2LoggingSystem returned a hard-coded list of standard
config locations that includes both JSON and XML file suffixes. Log4j
2’s support for JSON configuration files requires Jackson’s ObjectMapper
to be on the classpath so, in its absence, the standard config locations
were incorrect.
This commit updates Log4J2LoggingSystem to return an array of standard
config locations based on what’s on the classpath. It also updates the
documentation to describe the additional dependencies that are required
to enable YAML or JSON-based configuration.
Closes gh-2239
