New library: Across test

/wiki/spaces/AX/pages/12648455 contains some helper classes and configurations to quickly setup an AcrossContext with or without AcrossWebModule.  Also has a setup to facilitate multi-database testing, see Integration tests.

New modules

• OAuth2Module providing OAuth2 security services and a domain model for managing clients and permissions (built on top of SpringSecurityModule and UserModule)
• PropertiesModule providing a generic infrastructure to create database backed property maps for business entities

Across core

• enhancement: Controllers are no longer exposed by default - only Service beans and beans with Exposed annotation
•  enhancement: upgraded MBassador to version 1.1.10 (#15)
  • classes have been moved from package, MessageHandlerMetadata appears to have been dropped - custom filters might need fixing
•  enhancement: bootstrap hooks have been extended (#19)
  • introduced AcrossBootstrapConfig class
  • changed method signature: AcrossModule.prepareForBootstrap( ModuleBootstrapConfig currentModule, AcrossBootstrapConfig contextConfig)
•  enhancement: installer configuration on context and modules has been refactored
  • added InstallerSettings property on both AcrossContext and AcrossModule (setAllowInstallers() has been replaced by setInstallerAction())
  • added InstallerAction enumeration with an option to force run installers even if installed version is equal or higher (#14)
  • installers can be defined either as instance or Class
  • @AcrossDepends can now be used on installers as well (#13)
  • @AcrossDepends no longer supports expression attribute, a new @AcrossCondition annotation has been introduced for this
• enhancement: provided AcrossContextBeanRegistry for retrieving beans from context and modules (#39)
  
  • the registry can be used to fetch both exposed beans and module internal beans
  • the bean registry is also available in the parent application context if exposing to parent is enabled
• enhancement: extended availability of AcrossContextInfo and AcrossModuleInfo
  • AcrossContextInfo is exposed to parent application context
  • Introduced @Module annotation 
    • wire either AcrossModule or AcrossModuleInfo for a module with the specified name
    • wire the current AcrossModule or AcrossModuleInfo using AcrossModule.CURRENT_MODULE
    • wire an exposed bean from a specific module
  • AcrossModuleInfo exposes the bootstrap index of the module, AcrossContextInfo has helper methods to find the index of a module
• enhancement: scanning for beans in all modules (AcrossContextUtils.getBeansOfType) and the RefreshableRegistry now return instances sorted according to order hierarchy (#20)
  • Order annotation and Ordered interface
  • bootstrap index of the module
  • OrderInModule annotation and OrderedInModule interface
• ehancement: exposing beans now support lazy and scoped beans, and bean management will always and only happen within the module defining the original bean (#28)
  •  a parent ApplicationContext should either be an instance of AcrossApplicationContext or AcrossWebApplicationContext to fully support exposed beans
    • in a web context this usually means configuring the created contextClass to be AcrossWebApplicationContext instead of AnnotationConfigWebApplicationContext
    • in case this isn't so, an additional context will be introduced in the hierarchy, allowing for autowiring of exposed beans but limited integration with third party libraries (especially in web context)
  •  exposed beans now use a specific ExposedBeanDefinition and the optional transformer has been modified into ExposedBeanDefinitionTransformer with a different signature
• enhancement: Across bootstrap now locks on the database if installers need executing (#23)
  • this should avoid race conditions when bootstrapping multiple applications simultaneously on the same database, downside is the possible slower startup time in simultaneous deploys
  • core also provides a DistributedLockRepository that modules can use to lock entities on a database level and across application instances
• enhancement: new DatabaseInfo class allowing easy detection of the database product type based on a DataSource
•  Foreach commons upgraded to 0.9
  • Packages have been restructured, common-concurrent library has been added

AcrossWebModule

• bugfix: Scan inherited @Controller annotations, picks up @RestController instances (#16)
• bugfix: Default message converters are now registered if none specified (#17)
• bugfix: Redirects are now handled correctly if only Thymeleaf support is enabled (#22)
• enhancement: Across web module now configures a WebTemplateRegistry
  • default template support can be disabled using property
  • option to automatically scan modules for NamedWebTemplateProcessor instances

DebugWebModule

•  enhancement: DebugWebModule and AdminWebModule now use the same templating and handler mapping approach (#3) 
• feature: Provided DebugWeb bean (debugWeb) in analogy with AdminWeb for redirects and paths within debug context
• feature: dropped old debug pages and added more detailed Across/Context browsing page - switched to Twitter bootstrap (#18)

SpringSecurityModule

• added SpringSecurityInfrastructureModule providing infrastructure for common SecurityPrincipal implementation
  • note that this module is automatically inserted with the SpringSecurityModule, and should rarely be configured manually
• added SpringSecurityAclModule enabling ACL security services

UserModule

• added SecurityPrincipal implementation for User, Group and MachinePrincipal
