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 provides first-class support for Bean Overrides
(@MockitoBean, @MockitoSpyBean, @TestBean, etc.) with
@ContextHierarchy.
Specifically, bean overrides can now specify which ApplicationContext
they target within the context hierarchy by configuring the
`contextName` attribute in the annotation. The `contextName` must match
a corresponding `name` configured via @ContextConfiguration.
For example, the following test class configures the name of the second
hierarchy level to be "child" and simultaneously specifies that the
ExampleService should be wrapped in a Mockito spy in the context named
"child". Consequently, Spring will only attempt to create the spy in
the "child" context and will not attempt to create the spy in the
parent context.
@ExtendWith(SpringExtension.class)
@ContextHierarchy({
@ContextConfiguration(classes = Config1.class),
@ContextConfiguration(classes = Config2.class, name = "child")
})
class MockitoSpyBeanContextHierarchyTests {
@MockitoSpyBean(contextName = "child")
ExampleService service;
// ...
}

This commit introduces null-safe support for java.util.Optional in the
following SpEL operators:
- PropertyOrFieldReference
- MethodReference
- Indexer
- Projection
- Selection
- Elvis
Specifically, when a null-safe operator is applied to an empty
`Optional`, it will be treated as if the `Optional` were `null`, and
the subsequent operation will evaluate to `null`. However, if a
null-safe operator is applied to a non-empty `Optional`, the subsequent
operation will be applied to the object contained in the `Optional`,
thereby effectively unwrapping the `Optional`.
For example, if `user` is of type `Optional<User>`, the expression
`user?.name` will evaluate to `null` if `user` is either `null` or an
empty `Optional` and will otherwise evaluate to the `name` of the
`user`, effectively `user.get().getName()` for property access.
Note, however, that invocations of methods defined in the `Optional`
API are still supported on an empty `Optional`. For example, if `name`
is of type `Optional<String>`, the expression `name?.orElse('Unknown')`
will evaluate to "Unknown" if `name` is an empty `Optional` and will
otherwise evaluate to the `String` contained in the `Optional` if
`name` is a non-empty `Optional`, effectively `name.get()`.
