Commit adf2c44b was an attempt to prevent HSQLDB from throwing an
exception when the JVM exits. This was achieved by disabling the
application context’s shutdown hook in the tests. This had the unwanted
side effect of causing tests’ application contexts not to be closed. The
reported symptom was that @Destroy methods were no longer being invoked.
We need a different solution to the problem.
The exception was:
Caused by: org.hsqldb.HsqlException: Database lock acquisition failure: attempt to connect while db opening /closing
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.DatabaseManager.getDatabase(Unknown Source)
at org.hsqldb.DatabaseManager.newSession(Unknown Source)
... 23 common frames omitted
I originally thought this was due to a race between the application
context’s shutdown hook and HSQLDB’s shutdown hook, however HSQLDB
doesn’t use a shutdown hook. I believe that the problem is due to
an HSQLDB database being created with shutdown=true in its URL, similar
to the problem described here [1]. This will shut down the database when
the last connection to it is closed, however the shutdown will happen
asynchronously. If the JVM then runs the application context’s shutdown
hook, EmbeddedDatabaseFactory will attempt to connect to the database to
execute the SHUTDOWN command. This executes synchronously but will race
with the asynchronous shutdown that’s executing as a result of
shutdown=true in the JDBC url and the last connection to the database
being closed.
This commit reinstates the use of application context shutdown hooks in
the tests, and updates the documentation to recommend that, if a user
manually configures the URL for their embedded database, they do so
in such a way that the database doesn’t shutdown automatically, thereby
allowing the shutdown to be driven by application context close.

Spring Boot will eagerly initialize a `ConversionService` named
`conversionService` for configuration keys processing. This commit adds
a note in the documentation regarding that special behaviour.
Closes gh-4162
Previously, if Solr 5 was on the classpath, SolrAutoConfiguration
would fail with a rather cryptic error message due to a change in the
inheritance hierarchy of CloudSolrServer between Solr 4 and Solr 5.
This commit updates SolrAutoConfiguration to be conditional on a
class that exists in Solr 4 but was removed in Solr 5. This has the
effect of switching off the auto-configuration when Solr 5 is on
the classpath, allowing the auto-configuration report to be used to
identify why the configuration was disabled. The documentation has
also been updated to state that Spring Boot does not currently support
Solr 5.0.
Closes gh-2795
This commit changes the new mode-based configuration to use two new
methods – setBannerMode on SpringApplication and bannerMode on
SpringApplicationBuilder. The old methods, setShowBanner and
showBanner on SpringApplication and SpringApplicationBuilder
respectively, have been reinstated and deprecated.
Closes gh-4001
This commit adds the option to output the banner using the logger
instead of standard out. Rather than taking a boolean
spring.main.show-banner is now configured using an enum. Three values
are supported:
- LOG: the banner is logged
- CONSOLE: the banner is printed to standard out (previously true)
- OFF: the banner is switched off (previously false)
The default behavior remains unchanged; the banner will be printed to
standard out.
Closes gh-4022

Provide a general purpose Hazelcast integration (i.e. not tied to caching).
Auto-configure a `HazelcastInstance` either based on the presence of a
`Config` bean or a configuration file. Said configuration file can be
specified explicitly or automatically found from default locations.
The cache integration already supports Hazelcast so it has been reworked
to automatically reuse an existing `HazelcastInstance` if available.
Closes gh-2942
Users sometimes create beans of type Converter and don't expect that to
automatically trigger a cascade of early initialization. This change adds
a qualifier to the Converters that are used by @ConfigurationProperties,
so they can be isolated (and simple).
Fixes gh-2669
Spring MVC requires all handlers for the same path to be on the same handler
so if anyone wants to add new handlers for different content types they
have to copy a lot of code from BasicErrorController. This change increases
the visibility of the basic utility methods in BasicErrorController so that
custom handlers can be added easily.
Fixes gh-3828
This commit adds a new annotation, @ServletComponentScan, that can be
used to enable scanning for @WebFilter, @WebListener, and @WebServlet
annotated classes. Registration beans will be automatically created for
any classes that are found, with the configuration derived from the
annotation.
Previously, native cache libraries were favored over a standard JSR-107
implementation. If a user has a working setup using JCache with one
provider and switch to another provider, his setup may be broken if we
happen to provide a native support for the new provider.
We now consistently favor JSR-107 if it is present. Native support can
still be enabled via the `spring.cache.type` property.
Closes gh-3822
Given that Spring Boot uses java config accross the board, a new `value`
attribute is now aliased to the existing `classes` attribute such that
one could write the following:
@SpringApplicationConfiguration(MyConfig.class)
public class MyTest {}
Closes gh-3635
A new `spring.datasource.type` property can now be used to configure the
connection pool implementation to use (rather than only relying on Boot's
preferences).
Closes gh-3705
Improve the documentation to explain the necessary steps to create a
custom Spring Boot starter. In particular, provide more details regarding
naming conventions.

Previously, to use a custom ConfigurableWebBindingInitializer, it was
necessary to extend WebMvcConfigurationSupport and override
getConfigurableWebBindingInitializer. This had the unwanted
side-effect of switching off the auto-configuration of Spring MVC.
This commit updates the auto-configuration to look for a
ConfigurableWebBindingInitializer bean and register it with Spring
MVC.
Closes gh-2526
This commit adds a new property, logging.exception-conversion-word,
that can be used to configure the conversion word that is used when
logging exceptions. The default value, %rEx, will log exceptions
with the root cause first and include class packaging information in
the stack trace. The new property is supported when using either
Logback or Log4J2.
Closes gh-3684
Three conditions must be met for the console to be enabled:
- H2 is on the classpath
- The application is a web application
- spring.h2.console.enabled is set to true
If spring-boot-devtools is on the classpath, spring.h2.console.enabled
will be set to true automatically. Without the dev tools, the enabled
property will have to be set to true in application.properties.
By default, the console is available at /h2-console. This can be
configured via the spring.h2.console.path property. The value of this
property must begin with a '/'.
When Spring Security is on the classpath the console will be secured
based on the user's security.* configuration. When the console is
secured, CSRF protection is disabled and frame options is set to
SAMEORIGIN for its path. Both settings are required in order for the
console to function.
Closes gh-766
Add an auto-configuration that avoid a Spring Boot user to add
`@EnableConfigurationProperties` to its configuration to benefit from
that feature.
As our own auto-configurations are tested independently, such annotation
is still present to avoid a useless reference to this new
auto-configuration.
Closes gh-2457
Update Tomcat, Jetty and Undertow to serialize session data when the
application is stopped and load it again when the application restarts.
Persistent session are opt-in; either by setting `persistentSession`
on the ConfigurableEmbeddedServletContainer or by using the property
`server.session.persistent=true`.
Fixes gh-2490
Embedded MongoDB is now auto-configured when it is on the classpath.
The Mongo instance will listen on the port specified by the
spring.data.mongodb.port property. If this property has a value of
zero and randomly allocated port will be used. In such an event, the
MongoClient created by MongoAutoConfiguration will be automatically
configured to use the port that was allocated.
By default, MongoDB 2.6.10 will be used. This can be configured using
the spring.embedded-mongodb.version property. Mongo's sync delay
feature is enabled by default. This can be configured using the
spring.embedded-mongobd.features property.
Closes gh-2002
Add ApplicationArguments interface which allows SpringApplication.run
arguments to be injected into any bean. The interface provides access
to both the raw String[] arguments and also provides some convenience
methods to access the parsed 'option' and 'non-option' arguments.
A new ApplicationRunner interface has also been added which is
similar to the existing CommandLineRunner.
Fixes gh-1990
Unfortunately, we have no other choice to flip the ignoreUnknownFields
attribute of `SecurityProperties` has many different target are now set
for that namespace outside the class. See gh-3445 for a potential way
to improve that.
Closes gh-3327
Use AbstractTemplateViewResolverProperties as the base class for
GroovyTemplateProperties since the Spring GroovyMarkupViewResolver is
an AbstractTemplateViewResolver.
The auto-configuration for Groovy is now more aligned with the existing
Freemarker and Velocity auto-configuration, with a `resourceLoaderPath`
property being used instead of `prefix`.
Fixes gh-3365
Closes gh-3374
There is a new spring.factories entry for
org.springframework.boot.actuate.autoconfigure.EndpointWebMvcConfiguration
which loads extra beans into the MVC config for the Actuator.
If the management context is a child context all the beans go in the
child (except the Spring Security filter still). A big bonus is that
you can add WebConfigurerAdapters to configure static resources etc.
A new component called ManagementContextResolver can be used to
locate the ApplicationContext for the MVC endpoints.
Fixes gh-3345
This commit improves support of the Resource Handling features
introduced in Spring Framework 4.1. Those features add new ways to
resolve and transform static resources in applications.
See [this blog
post](https://spring.io/blog/2014/07/24/spring-framework-4-1-handling-static-web-resources)
for more details.
The `ResourceUrlEncodinFilter` is added for compatible template engines:
Velocity and Thymeleaf. It assists them with rewriting the URLs of
static resources when rendering templates.
New keys are added in the `ResourceProperties` in order to configure
the Resource Handling chain. `ResourceResolvers` and
`ResourceTransformers` are registered accordingly in
`WebMvcAutoConfiguration`.
Here is an example of enabling a `ContentVersionStrategy` on all
static resources, meaning their names will be changed for cache
busting purposes by adding a content hash at the end of the file name.
Like "/js/jquery.js -> /js/jquery-872ca6a9fdda9e2c1516a84cff5c3bc6.js".
```
spring.resources.chain.enabled:true
spring.resources.chain.strategy.content.enabled:true
spring.resources.chain.strategy.content.paths:/**
```
Closes gh-1604
Closes gh-3123
Add AnsiPropertySource which allows named ANSI codes to be resolved
and update ResourceBanner to include it.
This commit also deprecates constants defined in AnsiElement and
replaces them with AnsiStyle, AnsiColor and AnsiBackground enums.
Closes gh-2704
This commit adds support for automatically configuring Spring Session.
In a web application when both Spring Session and Spring Data Redis
are on the classpath, Spring Session's Redis Http Session support
will be auto-configured. The max inactive interval for Redis-backed
sessions can be configured via the environment using the existing
server.session-timeout property.
Closes gh-2318
Improve SpringApplicationAdminMXBean to expose additional information:
* Whether the application uses an embedded container
* The properties exposed by the `Environment`
This allows to know if the application is web-based and the HTTP port
on which it is running.
