Users can declare or Command, OptionHandler classes in an init script
or they can use a DSL, e.g.
command("foo") { args -> println "Do stuff with ${args} array" }
or
command("foo") {
options { option "bar", "Help text for bar option" ithOptionArg() ofType Integer }
run { options -> println "Do stuff with ${options.valueOf('bar')}" }
}
InitCommand runs on creation of SpringCli so it can search for additional
Commands in updated classpath. Also added as interactive command in Shell
session.
PropertiesLauncher now supports creating its own class loader
from looader.classLoader property. It will succeed if the
implementation specified has a default constructor or one
that takes a parent class loader, or one that takes a URL[]
and a parent class loader (like URLClassLoader).
The collection of outcomes is a list. Sometimes a race condition causes to instances
of the same outcome to get added to the list shown in the report. By replacing this
with a set and propery equals/hashCode, duplicates are prevented from appearing
in the report.
I added test cases to prove that that POJO is properly managed inside a Set and also
to show that duplicates don't appear in the final report.
Autoconfiguration ordering has to be adjusted so that a DataSource is
available before an EntityManagerFactory is ever needed. Previously
the autoconfigs were accidentally loaded in the right order, but after
the change to BatchAutoConfiguration the order has to be explicit.

Change SpringCli so that running without arguments no longer jumps into
the embedded REPL shell. This restores the ability to obtain quick usage
help by simply typing `spring` from the command prompt.
Windows users or developers that prefer the embedded shell can still
launch it using `spring shell`.
Change OptionHandler to support '-cp' instead of '--cp'. This update
to the original fix (045088e8b) renders `help` output correctly and
should prevent potential issues if a `-p` command is added in the future.
Fixes gh-178
Defer loading of Servlets (with a loadOnStartup priority) until
the `EmbeddedServletContainer.start()` method is called. This prevents
issues with the DispatcherServlet being initialized before the embedded
ApplicationContext is fully initialized.
Long package names are really unnecessary in samples and they
just clutter things up. Also Spring Loaded doesn't work with
org.sfw packages, so to demo that technology you need a
different package name.
Main user-facing interface is still Counter/GaugeService but the
back end behind that has more options. The Default*Services write
metrics to a MetricWriter and there are some variants of that, and
also variants of MetricReader (basic read-only actions).
MetricRepository is now a combination of MetricReader, MetricWriter
and some more methods that make it a bit more repository like.
There is also a MultiMetricReader and a MultiMetricRepository for
the common case where metrics are stored in related (often open
ended) groups. Examples would be complex metrics like histograms
and "rich" metrics with averages and statistics attached (which
are both closed) and "field counters" which count the occurrences
of values of a particular named field or slot in an incoming message
(e.g. counting Twitter hastags, open ended).
In memory and redis implementations are provided for the repositories.
Generally speaking the in memory repository should be used as a
local buffer and then scheduled "exports" can be executed to copy
metric values accross to a remote repository for aggregation.
There is an Exporter interface to support this and a few implementations
dealing with different strategies for storing the results (singly or
grouped).
Codahale metrics are also supported through the MetricWriter interface.
Currently implemented through a naming convention (since Codahale has
a fixed object model this makes sense): metrics beginning with "histogram"
are Histograms, "timer" for Timers, "meter" for Meters etc.
Support for message driven metric consumption and production are provided
through a MetricWriterMessageHandler and a MessageChannelMetricWriter.
No support yet for pagination in the repositories, or for HATEOAS style
HTTP endpoints.
Added the necessary @ConditionalOnMissingBean annotations to allow selectively declaring an EntityManagerFactoryBean, a JpaVendorAdapter or a PlatformTransactionManager. Especially the first one might be necessary to make sure the persistence provider evaluates an orm.xml. This unfortunately rules out using the packages to scan feature of Spring's LCEMFB.
I've filed https://jira.springsource.org/browse/SPR-11260 to potentially remove the need for this workaround in Spring itself.
If Logback and another SLF4J implementation are both on the classpath
it is possible for the LogbackLoggingSystem to fail to locate
a LoggerContext. Rather than a ClassCastException it is better to
make an assertion with an error message.
