Prior to this commit LoggingSystem initialization would happen multiple
times. Once to configure "quiet" logging, and again to configure correct
settings once the Application was initialized. This could cause problems
if `logging.groovy` logback files were used.
The logging system is now only initialized once (when possible) by
following these steps:
- Standard logging initialization occurs via the actual logging
implementation used (e.g. logback will load a logback.xml file if it
exists)
- beforeInitization() is called to prevent early log output.
Implementations now either use a Filter or simply set the root logging
level.
- initialize() is called with an optional log configuration file (e.g
a custom logback.xml location) and an optional log output file (the
default is null indicating console only output).
The initialize() method will attempt to prevent double initialization
by checking if a standard configuration file exists. Double
initialization now only occurs in the following situations:
- The user has a standard configuration file (e.g. classpath:logback.xml)
but also specifies a logging.config property. Double initialization is
required since the specified configuration file supersedes the default.
- The user has a standard configuration file (e.g. classpath:logback.xml)
and specifies a logging.file property. Double initialization is
required since the standard configuration may use a ${LOG_FILE}
reference.
In addition this commit removes the `logging.console` option and now
assumes that logging either occurs only to console or to both the
console and a file. This restriction helps simplify the LoggingSystem
implementations. If file only logging is required a custom logback.xml
can be used.

Then we can optionally find a non-anonymous principal if there
is one. If the user is anonymous then the health result is cached
up to endpoints.health.ttl (default 1000ms) to prevent a DOS attack.

Spring 4.2 has a @TestPropertySource which has some of the features of
@IntegrationTest. This change adds @TestPropertySource to the @IntegrationTest
annotation, so that (for instance) the cache key for the context includes
properties for the test.
Since @IntegrationTest has slightly different semantics I do not propose to
deprecate it. Users can use it or @TestPropertySource, the main difference being that
with @IntegrationTest the Spring Boot context loader is aware of the annotation
and it will set sensible defaults for server.port and spring.jmx.enabled.
There are some reflection hacks to overcome the usual fortifications of Spring Test.
Fixes gh-1697
Replace where possible all @ConditionalOnExpression annotations with
@ConditionalOnProperty which is both faster to run and more descriptive.

Previously, for a string to be considered upper-case,
EmbeddedServerPortFileWriter required every character in the
string to be upper-case. This meant that strings containing numbers were
considered lower-case even if every letter in the string was upper-case.
OS X’s case-preserving, case-insensitive file system masked this problem
as the tests were still able to find the created file, even though the
case of its name was not as expected.
This commit updates EmbeddedServerPortFileWriter to only require
characters that are letters (as defined by Character.isLetter()) to be
upper-case. It also updates the tests to verify that the case of the
created file’s name is correct in such a way that it will fail, even
on OS X, when it is not.

- Supply auto-configuration for the new indicator
- As suggested in the pull request, include the free disk space and
configured threshold in the health details
- Update the documentation to describe the indicator and its
two configuration settings
- Use @ConfigurationProperties to bind the indicator's configuration.
This should make the changes sympathetic to the work being done
to automate the configuration properties documentation

In addition to requiring the Servlet API to be on the classpath,
MetricFilter requires spring-web to also be on the classpath as it
extends OncePerRequestFilter. This commit updates the auto-configuration
for MetricFilter so that it will be disabled in the absence of a
dependency on spring-web.
Fixes gh-1664
Some weird looking test failures led me to track this down.
If the user changes the prefix for metric names, he probably wanted
to change the keys as welll (otherwise 2 repositories can use the
same key, which is why the test was failing for me). We can do that
in an afterPropertiesSet().
If the actuator endpoints are configured on a different port then there
are some settings in the main ServerProperties that we would like to
re-use (e.g. the access log). The easiest way to do that is to just
configure the management server using the same ServerProperties instance
and then overwrite the things that are different (and stored in
ManagementServerProperties).
Fixes gh-1581
Done in order to align with the rest of the configuration. Absent this
check, the bean will be installed in non-web applications without the
corresponding dependencies, causing the bootstrap to fail.
Closes gh-1588
This is a continuation of the changes made in 611f978. It makes some
more @Bean methods public and adds tests to spring-boot-actuator and
spring-boot-autoconfigure to prevent against non-public methods being

When MVC path matchers are used as metric keys, they can still contain
invalid characters and patterns (like asterisks). This change removes
some more special characters and also tidies up the names a bit so
no key part starts or ends with "-" (which is ugly).

Protecting /error doesn't make a great deal of sense and if it is
protected you don't get the ErrorPageFilter for the attempt at loading
it, so Tomcat renders its own HTML error page (when deployed as WAR).

Import DataSourcePoolMetadataProvidersConfiguration from
DataSourceAutoConfiguration so that PoolMetadataProviders are configured
even if actuator is not used.
This commit improves DataSourceMetadata to expose the validation
query. This can be used by DataSourceHealthIndicator as the query
to use instead of "guessing" which query could be applied according
to the database type.
Fixes gh-1282
This commit adds an abstraction that provides a standard manner to
retrieve various metadata that are shared by most data sources.
DataSourceMetadata is implemented by the three data source
implementations that boot supports out-of-the-box: Tomcat, Hikari and
Commons dbcp.
This abstraction is used to provide two additional metrics per data
source defined in the application: the number of allocated
connection(s) (.active) and the current usage of the connection pool
(.usage).
All such metrics share the 'datasource.' prefix. The prefix is further
qualified for each data source:
* If the data source is the primary data source (that is either the
only available data source or the one flagged @Primary amongst the
existing ones), the prefix is "datasource.primary"
* If the data source bean name ends with "dataSource", the prefix is
the name of the bean without it (i.e. batchDataSource becomes batch)
* In all other cases, the name of the bean is used
It is possible to override part or all of those defaults by
registering a bean with a customized version of
DataSourcePublicMetrics.
Additional DataSourceMetadata implementations for other data source
types can be added very easily, check
DataourceMetadataProvidersConfiguration for more details.
Fixes gh-1013
if user also adds @EnableWebMvcSecurity. The problem is that the ordering
of the init() and configure() methods in the Spring Security configurers
can force things to happen too early unless we are careful. It's still a bit
twitchy I would say, but this relatively small change seems to fix the GS guide
and not break any existing tests.
I added a sample which mimic ths GS guide so we get an integration test that
executes the new code paths.

Rename `VanillaHealthIndicator` to `ApplicationHealthIndicator` and
changed the exposed bean name from `statusHealthIndicator` to
`applicationHealthIndicator`.
This provides less confusing JSON output:
{"status":"UP","application":{"status":"UP"}}
vs:
{"status":"UP","status":{"status":"UP"}}
Fixes gh-1291
JSON output of /health now has the same structure for 1 or more HealthIndicators. This makes it easier to consume the response from scripts or apps

Rework flexible PublicMetrics registration introduced in 2be6b3e4 to
restore compatibility with v1.1 VanillaPublicMetrics. The new
MetricReaderPublicMetrics class now exposes metrics from a MetricReader
and VanillaPublicMetrics is deprecated. The MetricsEndpoint can now
exposes a collection of PublicMetric interface directly.

Previously, when running on Java 7+, the JDBC query driven by
DataSourceHealthIndicator resulted in a call to
ResultSet.getObject(index, Object.class). When using MySQL's JDBC
driver this failed with an SQLException with the message "Conversion
not supported for type java.lang.Object". The problem does not occur
on Java 6 as the overload of getObject that takes a type does not
exist; ResultSet.getObject(index) is called instead and MySQL happily
returns whatever type it deems to be appropriate for the column.
This commit updates DataSourceHealthIndicator so that
ResultSet.getObject(index) will always be used, irrespective of the
version of Java that Boot is running on.

Previously any custom http code mapping would remove the default mappings. With this commit the behaviour is changed so that default mappings will stay if a custom mapping is registered. Certainly a default mapping can be overridden.

This commit permits the use of several PublicMetrics instances by
default. Previously, only one PublicMetrics service could be specified
and a user configuration would remove all the defaulting.
VanillaPublicMetrics now takes a collection of PublicMetrics and
invokes them in sequence to build the final collection of metrics.
The system-related metrics have been moved to SystemPublicMetrics and
are registered by default.
Also updated the documentation to mention this feature and how it
could be fully overridden.

In order to solve issues with multiple or incompatible AccessDecisionManagers, the CRaSH integration will now only delegate to an explicit shellAccessDecisionManager bean refs #1121
Prior to this commit, some tests were creating a parent/child
relationship but were only closing the child context. This could
be an issue with the autoconfig module as a lot of auto-config
kicks in by default.
This commit adds a new test utility designed to properly handle
those situations. Updated tests that were creating a context
hierarchy to benefit from that.
Fixes gh-1034
The Actuator endpoints ought to take precedence over others (since
they are important and users can isolate them using management.contextPath
if necessary). This change puts the @Order at -100 (well before the default
order of the RequestMappingHandlerMapping at 0).

To ensure an MBeanServer is available when needed you have to
look in JNDI before resorting to the JDK platform factory.
I had to copy some private code from Spring, but it seems
worth it.
Fixes gh-1092
Anywhere that an MBeanServer is needed it should be
created @Conditionally, so that user can exclude the
JmxAutoConfiguration and still get the other JMX
behaviours automatically.
They all want to create an MBeanServer and when that happens
user sees no MBeans, or sometimes just one set (Spring Core,
Spring Integration or Spring Boot). To harmonise them we
create a @Bean of type MBeanServer and link to it in the
other autoconfigs

Not having READMEs in github is a mistake IMO, so here's one
restored and with a link to the docs. Docs also updated to
more accurately reflect the location of the actuator features
in implementation.

Actually the web-secure sample is misusing
security.basic.enabled=false (IMO) - it should be a flag
to say that you want to temporarily disable the basic security
fallback on application endpoins, not way to disable all

Added test case to web-secure sample to ensure a user
can log in.

Update Health and Status objects to be immutable, update the existing
builder methods to return new instances and add static convenience
methods to Health.
The in-memory version has to force the incoming metric keys to
start with the group name. Redis doesn't have that restriction
but normally we expect both to be used in such a way that
the metric keys already match the prefix. In that case the two
repositories behave the same now in terms of set and get.
In the redis repository we also switch to store the value in the
zset (so it can be atomically incremented) rather than in the
regular key-value.
Fixes gh-929
With this commit the state of a component or subsystem becomes a first-class citizen in Boot's application health support. HealthIndicators now return a Health instance with status and some contextual details.
An aggregation strategy has been introduced to aggregate several Health instances into one final application Health instance. Out of the box OrderedHealthAggregator can be configured to allow different ordering or a custom HealthAggregator bean can be registered.
The prefix needs to be added before looking for keys. In addition
I rationalized the constructor and final fields (it didn't make
any sense for the prefix to be mutable).
Fixes gh-927
The PrefixMetricGroupExporter only really makes sesne if the writer
is aware of the groups, so it seemed better to use a new interface
than mix read/write.
Update all @PostConstruct methods to ensure that they don't throw
checked exceptions. Required to allow deployment of Spring Boot
applications on Glassfish.
Fixes gh-868
We now have a much simpler DataSourceAutoConfiguration that binds to whatever
DataSource concrete type it finds at runtime. To be able to quickly switch between
Hikari and the other types of DataSource there's a minute shim for translating
the common properties (username, password, url, driverClassName), but actually
only url is different. The shim and also DataSource initialization is supported
through DataSourceProperties, but the other native properties get bound directly
through the concrete runtime type of the DataSource.
The /configprops endpoint works (and is exposed in the actuator sample).
Fixes gh-840, fixes gh-477, see also gh-808.
Introspects the properties that are being exposed in the report
and only renders the ones that are a) convertible from String
and b) have a setter. That goes a long way to making it a bullet
proof generic renderer of any Java object that can be bound with
@ConfigurationProperties.
Update the BasicErrorController so that it no longer needs to implement
@ControllerAdvice or have an @ExceptionHandler method.
A new ErrorAttributes interface is now used to obtain error details,
the DefaultErrorAttributes implementation uses a
HandlerExceptionResolver to obtain root exception details if the
`javax.servlet.error.*` attributes are missing.
This change also removes the need for the extract(...) method on
ErrorController as classes such as WebRequestTraceFilter can
now use the ErrorAttributes interface directly.

For the convenience of users who want to selectively override the
access rules in an application without taking complete control of the
security configuration we now have some constants:
* SecurityProperties.ACCESS_OVERRIDE_ORDER for overriding just the
application endpoint access rules
* ManagementServerProperties.ACCESS_OVERRIDE_ORDER for overriding the
application endpoint and management endpoint access rules
Fixes gh-803
Refactored HealthEndpoint to be able to take multiple HealthIndicators. Extracted configuration of HealthIndicators out of EndpointAutoConfiguration and added new HealthIndicatorAutoConfiguration class.
