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.
Fixes gh-189
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.
We get more control over the handling and in particular the registration
of the endpoint this way. It was practically impossible to disable the
AgentServlet bean when in a parent context of the management server
because of lifecyce issues - you don't know that the user wants a
separate management server until too late.
This approach also makes it possible to test with spring-test MVC
support.
You can contribute additional HttpMessageConverters
by simply adding beans of that type in a Spring Boot
context. If a bean you add is of a type that would have been included
by default anyway (like MappingJackson2HttpMessageConverter for JSON
conversions) then it will replace the default value. A convenience
bean is provided of type MessageConverters (always available if you
use the default MVC configuration) which has some useful methods to
access the default and user-enhanced message converters (useful, for
example if you want to manually inject them into a custom
RestTemplate).
There are also some convenient configuration shortcuts for Jackson2.
The smallest change that might work is to just add beans of type
Module to your context. They will be registered with the default
ObjectMapper and then injected into the default message
converter. In addition, if your context contains any beans of type
ObjectMapper then all of the Module beans will be registered with
all of the mappers.
Previously it was @ConditionalOnMissingBean(CommandLineRunner.class)
which caued obvious problems when user wanted to add an unrelated
CLR.
Extended feature set so that a JobRegistry can also be used (with
spring.batch.job.name) and the whole idea can be switched off with
spring.boot.job.enabled.
ServerProperties formerly had an @OnMissingBeanCondition
that didn't restrict the hierarchy. It also asserts that
the current context (not including parents) contains such
a bean. This led to an inevitable failure when there was
an existing instance in the parent context.
Fixed by a) searching only the current context, b) not
adding a ServerProperties bean if the context is not a
web app.
Previously all EventListeners were eagerly instantiated
but that can cause problems because it happens quite early
in the lifecycle. Better to be explicit about the
supported types.
This leverages existing capabilities of teh JDK and the OS
to grab a port at random and not have it stolen by another
process. It's very hard to avoid that race condition in
pure Java code, so why bother?
User can set port<0 to disable autoStart of connectors (e.g.
to start a web application context but not have it listen on
any port). In that case the actual socket port will be set to
0 (and therefore if it ever starts up the local port will
be random).
