The method setPseudoRandomNumberBits actually sets the number of bytes. This
commit deprecates setPseudoRandomNumberBits and adds
setPseudoRandomNumberBytes. The default value is still 256 to remain passive
but will be updated in 4.x.
This change extends the namespace configuration of <remember-me>
with a 'form-parameter' attribute. The introduced attribute sets
the 'parameter' property of AbstractRememberMeServices.
This enables overriding the default value of
'_spring_security_remember_me' using the namespace configuration.
Previously wiring dependencies created with a FactoryBean into
MethodSecurityExpressionHandler &
MethodSecurityExpressionHandler.expressionParser and would cause
NoSuchBeanDefinitionException's to occur. These changes make it easier
(but not impossible) to avoid such errors.
The following changes were made:
- ExpressionBasedAnnotationAttributeFactory delays the invocation of
MethodSecurityExpressionHandler.getExpressionParser()
- MethodSecurityExpressionHandler is automatically wrapped in a
LazyInitTargetSource and marked as lazyInit=true
Provide abstractions for transferring a SecurityContext across threads.
The main concepts are the DelegatingSecurityContextCallable and the
DelegatingSecurityContextRunnable which contain a SecurityContext to establish before
delegating to a Callable or Runnable.
There are also wrapper implementations for each of the key java.util.concurrent and
spring task interfaces to make using the DelegatingSecurityContextCallable and
DelegatingSecurityContextRunnable transparent to users. For example a
DelegatingSecurityContextTaskExecutor which can be injected with a specific
SecurityContext or use the SecurityContext from the SecurityContextHolder at the time the
task is submitted. There are similar implementations for each of the key
java.util.concurrent and spring task interfaces.
Note that in order to get DelegatingSecurityContextExecutorService to compile with
JDK 5 or JDK 6 we could not use type safe methods. See
