Add converter support for `javax.time.Period` including:
String -> Period
Number -> Period
Period -> String
Period to Number conversion is not supported since `Period` has no
ability to deduce the number of calendar days in the period.
See gh-21136
This commit harmonizes the change made to @DefaultValue to the
annotation processor. If such annotation is added to a scalar value with
no value at all, no default value is produced.
Closes gh-18917
This commit changes uses of ClassLoader.loadClass to Class.forName for
consistency with what was initiated in #19342 and better compatibility
with GraalVM.
Closes gh-19824
Previously, when the configuration properties annotation processor
encountered a property that was the same as an outer type that had
already been processed, it would fail with a stack overflow error.
This commit introduces the use of a stack to track the types that
have been processed. Types that have been seen before are skipped,
thereby preventing a failure from occurring. We do not fail upon
encountering a recursive type to allow metadata generation to
complete. At runtime, the recursive property will not cause a problem
if it is not bound.
Fixes gh-18365
Update the configuration processor to use the newly introduced
`@ConstructorBinding` annotation to determine when meta data
should be generated from constructor parameters.
Prior to this commit, the processor had no good way to tell when
constructor parameters should be used instead of getters/setters.
Closes gh-17035
This commit makes sure that a ConfigurationProperties type contributed
by a `@Bean` factory method uses properties binding regardless of the
presence of a matching constructor.
`@Bean` method makes sure the user is in control and will be responsible
of creating the instance. As a result, binding of properties will not
happen there and therefore can only happen with regular JavaBean
accessors.
Closes gh-18184
Previously, the configuration processor would ignore any
@ConfigurationProperties-annotated methods that were not public. This
prevented metadata generation for package-private @Bean methods such
as those in DataSourceConfiguration's inner-classes for DBCP2, Hikari,
and Tomcat JDBC.
This commit updates the annotation processor so that it will process
any non-private method annotated with @ConfigurationProperties.
Fixes gh-18124
Apply checkstyle rule to ensure that private and package private
classes do not have unnecessary public methods. Test classes have
also been unified as much as possible to use default scoped
inner-classes.
