Allow `META-INF/spring-devtools.properties` files to be used by
application developers to declare is specific jars should be included
or excluded from the RestartClassLoader.
A typical example where this might be used is a company that develops
it's own set of internal JARs that are used by developers but not
usually imported into their IDE.

Update SpringApplication so that startup exceptions are only logged
once. A custom UncaughtExceptionHandler is now used when running in
the main thread to suppress errors that have already been logged.
Fixes gh-4423
During a restart, the Restarter runs all registered shutdown hooks. This
breaks Log4J2 as it leaves it in a shutdown state that leaves logging
switched off such that no output it produced when the application starts
up again.
This commit introduces a new RestartListener abstraction.
RestartListeners are notified prior to the application being restarted.
A Log4J2-specific implementation is provided that prepares Log4J2 for
restart by removing any shutdown callbacks from its shutdown callback
registry. This prevents the restart from shutting down Log4J2, ensuring
that it still functions when the application restarts.

Previously, ConfigFileApplicationListener was listed in spring.factories
as both an EnvironmentPostProcessor and an ApplicationListener. This
was problematic as ConfigFileApplicationListener is stateful and listing
it twice lead to two separate instances with separate state.
This commit restore ConfigFileApplicationListener to only being an
ApplicationListener. The driving of EnvironmentPostProcessors that was
performed by EnvironmentPostProcessingApplicationListener is now
performed by ConfigFileApplicationListener which adds itself as an
EnvironmentPostProcessor. This ensures that there’s only a single
instance of ConfigFileApplicationListener, allowing its state to be
managed correctly.
Closes gh-4258
Previously, the auto-configuration of DevTools’ debug, restart, and
health handlers assumed that the server was running on its default
context path and, if server.context-path was set to a non-default value,
the handlers would not work as expected.
This commit updates the auto-configuration of the three handlers to
consider the server’s context path when configuring their URIs. Now,
when a custom server context path is used, no further configuration is
required other than the inclusion of that context path when providing
the remote URL as an argument to RemoteSpringApplication.
Closes gh-4301
Replace the custom Base64Encoder class with Spring's Base64Utils which
since 4.2 can encode bytes using Java 8's encoder, commons-digest or
Java 6's JAX-B encoder.
Closes gh-4189
Spring HATEOAS’s DummyInvocationUtils, that is used by
ControllerLinkBuilder, uses Objenesis. By default, Objenesis caches
the instances that it creates and uses the class name as the cache key.
This is problematic when DevTools’ restart support is enabled as the
class loader changes with each restart and ClassCastExceptions occur
due to Objenesis returning a cached instance that was created by an
old restart class loader.
This commit works around the problem described above by auto-configuring
a bean that uses reflection to replace DummyInvocationUtils’ default
Objenesis instance with one that has caching disabled.
Closes gh-3784
Previously the default DevTools property source was added in first place
to the environment’s property sources in an unordered environment
post-processor. This made it difficult to override them.
This commit updates the post-processor to be ordered with lowest
precedence and to add the property source in last place. This should
allow any other property sources and to override the defaults.
Closes gh-3851
This commit adds two new properties, spring.devtools.remote.proxy.host
and spring.devtools.remote.proxy.port that can be used to configure
RemoteSpringApplication to connect to the remote application through
an HTTP proxy.
Closes gh-3968
Previously, if a file or non-existent directory was added to
FileSystemWatcher, it would fail with the message “Folder must not be a
file”. While it suggests that the folder needs to be a directory, it
doesn’t make it clear that it also needs to exist. It also doesn’t
tell the user which folder caused the problem.
This commit updates the message to make it clear that the folder must
exist and must be a directory, and the include the name of the
problematic folder in the error message.
Closes gh-3918
Update `DevToolsProperties` to exclude `git.properties` files.
Prior to this commit any application configured to write `git.properties`
could trigger unexpected application restarts. The problem is particularly
prevalent when using Eclipse M2E in combination with the
`git-commit-id-plugin`.
Closes gh-3938
Previously, dev tools would restart the application when any .class
file changed. This included test classes. This commit updates the
default excludes to ignore any classes with a name that ends in
Test.class or Tests.class.
Closes gh-3900
Previously, RemoteDevToolsAutoConfiguration would try to configure
Spring Security if it was on the classpath. This led to a failure if
Spring Security was on the classpath but its auto-configuration was
disabled.
This commit updates the auto-configuration to be conditional on the
presence of Spring Security’s ObjectPostProcessor bean.
See gh-3889
Previously, if an app had Spring Security on the classpath the remote
devtools server would be secured using basic authentication. This
prevented RemoteSpringApplication from uploading changes to the server
as they would be rejected with a 401.
This commit updates RemoteDevToolsAutoConfiguration to allow anonymous
access to the remote server. CSRF protection is also disabled so that
POST requests without a CSRF token will be accepted.
Closes gh-3889
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
The default value of `spring.devtools.restart.exclude` is quite long and
any override requires to copy/paste it to add additional exclusions. To
avoid that, a new `spring.devtools.restart.additional-exclude` property
has been added.
Both properties are now used to compute the full list of exclusions that
is used by PatternClassPathRestartStrategy.
