The @CacheConfig section of the reference manual provides an example
that declares @CacheConfig("books").
However, unlike the @Cacheable, @CachePut, and @CacheEvict
annotations, @CacheConfig currently does not have a `value` alias for
the `cacheNames` attribute. Thus, the example in the reference manual
does not compile, and @CacheConfig(cacheNames = "books") would be the
supported way to declare that.
The driving factor for this commit is therefore to provide a simplified
and consistent programming model for users that only need to define
default cache names at the type level (like in the existing example in
the reference manual).
To address that, this commit introduces a `value` alias for
`cacheNames` in @CacheConfig.

(cherry picked from commit 6091453feb)
This commit fixes a regression in PropertySourcesPlaceholderConfigurer
that was introduced in Spring Framework 6.2.7.
Specifically, this commit reinstates automatic String-conversion of
values from PropertySources in the Environment using the
ConversionService configured in the Environment.

that PropertySourcesPlaceholderConfigurer uses the ConversionService
from the Environment.

The setProperty() and withProperty() methods in MockEnvironment were
originally introduced with (String, String) signatures; however, they
should have always had (String, Object) signatures in order to comply
with the MockPropertySource and PropertySource APIs.
To address that, this commit changes the signatures of these methods so
that they only accept Object values for properties.
NOTE: this commit only affects the internal MockEnvironment used as a
test fixture. This commit does not affect the official, public
MockEnvironment implementation in spring-test.

Prior to this commit, a BeanDefinitionReader registered via
@ImportResource was required to be public and have a public
constructor that accepts a single BeanDefinitionRegistry. However, the
public visibility requirements are not necessary, and the requirements
for the constructor's formal parameter list is not documented.
To address those issues, this commit removes the public visibility
restrictions and documents that a BeanDefinitionReader registered via
@ImportResource must declare a constructor that accepts a single
BeanDefinitionRegistry.
In addition, this commit includes the cause of the instantiation
failure in case the registered BeanDefinitionReader cannot be
instantiated.

After the bootstrap phase (and with spring.locking.strict=true during the bootstrap phase), getSingletonFactoryBeanForTypeCheck always locks. In a background bootstrap thread, it never locks. Otherwise, it tries locking and explicitly resolves the bean class for subsequent type-based resolution (even for a component-scanned class) when it fails to acquire the lock. Furthermore, getObjectFromFactoryBean follows the same locking algorithm for post-processing.
Closes gh-34902
Spring Framework 6.2 introduced support for an escape character for
property placeholders (by default '\'). However, as of Spring Framework
6.2.6, there was no way to either escape the escape character or disable
escape character support.
For example, given a `username` property configured with the value of
`Jane.Smith` and a `DOMAIN\${username}` configuration string, property
placeholder replacement used to result in `DOMAIN\Jane.Smith` prior to
6.2 but now results in `DOMAIN${username}`. Similarly, an attempt to
escape the escape character via `DOMAIN\\${username}` results in
`DOMAIN\${username}`.
In theory, one should be able to disable use of an escape character
altogether, and that is currently possible by invoking
setEscapeCharacter(null) on AbstractPropertyResolver and
PlaceholderConfigurerSupport (the superclass of
PropertySourcesPlaceholderConfigurer).
However, in reality, there are two hurdles.
- As of 6.2.6, an invocation of setEscapeCharacter(null) on a
PropertySourcesPlaceholderConfigurer applied to its internal
top-level PropertySourcesPropertyResolver but not to any nested
PropertySourcesPropertyResolver, which means that the `null` escape
character could not be effectively applied.
- Users may not have an easy way to explicitly set the escape character
to `null` for a PropertyResolver or
PropertySourcesPlaceholderConfigurer. For example, Spring Boot
auto-configures a PropertySourcesPlaceholderConfigurer with the
default escape character enabled.
This first issue above has recently been addressed by gh-34861.
This commit therefore addresses the second issue as follows.
- To allow developers to easily revert to the pre-6.2 behavior without
changes to code or configuration strings, this commit introduces a
`spring.placeholder.escapeCharacter.default` property for use with
SpringProperties which globally sets the default escape character that
is automatically configured in AbstractPropertyResolver and
PlaceholderConfigurerSupport.
- Setting the property to an empty string sets the default escape
character to `null`, effectively disabling the default support for
escape characters.
spring.placeholder.escapeCharacter.default =
- Setting the property to any other character sets the default escape
character to that specific character.
spring.placeholder.escapeCharacter.default = ~
- Setting the property to a string containing more than one character
results in an exception.
- Developers are still able to configure an explicit escape character
in AbstractPropertyResolver and PlaceholderConfigurerSupport if they
choose to do so.
- Third-party components that wish to rely on the same feature can
invoke AbstractPropertyResolver.getDefaultEscapeCharacter() to obtain
the globally configured default escape character.

This commit overrides containsProperty() in
FallbackEnvironmentPropertySource for consistency with the
implementation of ConfigurableEnvironmentPropertySource.
See gh-34861
Although it's unlikely that the implementation of getPropertySources()
in a ConfigurableEnvironment would be overridden to return a different
MutablePropertySources instance than the one that the
ConfigurableEnvironment typically acts on, it is in fact possible.
In light of that possibility, this commit refactors
ConfigurableEnvironmentPropertySource so that it always obtains a fresh
PropertySources reference.
See gh-34861
Commit 3295289e17 fixed a number issues with placeholder resolution in
PropertySourcesPlaceholderConfigurer. However, in doing so, it replaced
a raw PropertySource with a CompositePropertySource which implements
EnumerablePropertySource.
Consequently, all property sources registered in the Environment must
now implement EnumerablePropertySource (which is not an actual
requirement). Otherwise, invocations of getPropertyNames() on the
CompositePropertySource result in an IllegalStateException, and that is
a breaking change which resulted in numerous build failures within the
Spring portfolio.
To address that regression, this commit introduces a private
ConfigurableEnvironmentPropertySource in
PropertySourcesPlaceholderConfigurer which is a "raw" PropertySource
that delegates directly to the PropertySources in a
ConfigurableEnvironment.
This commit also extracts the raw PropertySource for direct Environment
delegation into a new FallbackEnvironmentPropertySource.
See gh-17385
Closes gh-34861
Currently, the placeholder resolution algorithm in
PropertySourcesPlaceholderConfigurer fails in several scenarios, and
the root cause for this category of failures has actually existed since
PropertySourcesPlaceholderConfigurer was introduced in Spring Framework
3.1.
Specifically, PropertySourcesPlaceholderConfigurer creates its own
PropertySourcesPropertyResolver that indirectly delegates to another
"nested" PropertySourcesPropertyResolver to interact with
PropertySources from the Environment, which results in double
placeholder parsing and resolution attempts, and that behavior leads to
a whole category of bugs.
For example, #27947 was addressed in Spring Framework 5.3.16, and due
to #34315 and #34326 we have recently realized that additional bugs
exist with placeholder resolution: nested placeholder resolution can
fail when escape characters are used, and it is currently impossible
to disable the escape character support for nested resolution.
To address this category of bugs, we no longer indirectly use or
directly create a "nested" PropertySourcesPropertyResolver in
PropertySourcesPlaceholderConfigurer. Instead, properties from property
sources from the Environment are now accessed directly without
duplicate/nested placeholder resolution.

In commit 05ebca8677, the `public` modifier was removed from the
SpringAtInjectTckTests class, which prevents it from being run as a
JUnit 3 test class.
To address that, this commit adds the missing `public` modifier as well
as a a code comment to help prevent this from happening again.
In addition, this commit updates spring-context.gradle to ensure that
the JUnit Vintage test engine is always applied. However, that Gradle
configuration is unfortunately ignored due to how our TestConventions
class has been implemented. Thus, that issue will have to be addressed
separately.
