Given a @Configuration class named org.example.AppConfig which
contains @Bean methods, in Spring Framework 5.3.x and previous
versions, the following classes were created when generating the CGLIB
proxy.
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa
org.example.AppConfig$$FastClassBySpringCGLIB$$3fec86e
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa$$FastClassBySpringCGLIB$$82534900
Those class names indicate that 1 class was generated for the proxy for
the @Configuration class itself and that 2 additional FastClass
classes were generated to support proxying of @Bean methods in
superclasses.
However, since Spring Framework 6.0, the following classes are created
when generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$1
org.example.AppConfig$$SpringCGLIB$$2
The above class names make it appear that 3 proxy classes are generated
for each @Configuration class, which is misleading.
To address that and to align more closely with how such generated
classes were named in previous versions of the framework, this commit
modifies SpringNamingPolicy so that generated class names once again
include "FastClass" when the generated class is for a CGLIB FastClass
as opposed to the actual proxy for the @Configuration class.
Consequently, with this commit the following classes are created when
generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$1

The introduction of AdvisedSupport.AdvisorKeyEntry in Spring Framework
6.0.10 resulted in a regression regarding caching of CGLIB generated
proxy classes. Specifically, equality checks for the proxy class cache
became based partially on identity rather than equivalence. For
example, if an ApplicationContext was configured to create a
class-based @Transactional proxy, a second attempt to create the
ApplicationContext resulted in a duplicate proxy class for the same
@Transactional component.
On the JVM this went unnoticed; however, when running Spring
integration tests within a native image, if a test made use of
@DirtiesContext, a second attempt to create the test
ApplicationContext resulted in an exception stating, "CGLIB runtime
enhancement not supported on native image." This is because Test AOT
processing only refreshes a test ApplicationContext once, and the
duplicate CGLIB proxy classes are only requested in subsequent
refreshes of the same ApplicationContext which means that duplicate
proxy classes are not tracked during AOT processing and consequently
not included in a native image.
This commit addresses this regression as follows.
- AdvisedSupport.AdvisorKeyEntry is now based on the toString()
representations of the ClassFilter and MethodMatcher in the
corresponding Pointcut instead of the filter's and matcher's
identities.
- Due to the above changes to AdvisorKeyEntry, ClassFilter and
MethodMatcher implementations are now required to implement equals(),
hashCode(), AND toString().
- Consequently, the following now include proper equals(), hashCode(),
and toString() implementations.
- CacheOperationSourcePointcut
- TransactionAttributeSourcePointcut
- PerTargetInstantiationModelPointcut

This commit prints a log message at debug level without
a stacktrace for TypeNotPresentException and uses
warn level instead of error level for other exceptions
since the processing of such bean will just be skipped.
Closes gh-31147
Reuses ValidationAnnotationUtils which is slightly optimized for the detection of Spring's Validated annotation now, also to the benefit of common web scenarios.
