Across Platform 2.1.0 bumps Across core to a new major version (3.x) that greatly improves compatibility with standard Spring and Spring Boot. The Spring Boot dependency has also been updated from 1.4.x to 1.5.x.

This platform upgrade has a lot of updated modules, both with new features and technical (sometimes breaking) refactorings/improvements. We strongly advise you to read the module specific release notes for all details.

Migration guide

Platform 2.1.0 includes some major updates related to improving Spring Boot 1.5 compatibility. This introduces some breaking changes that require you to update your existing code base. A separate migration guide has been provided to help you upgrading from platform 2.0.x to 2.1.0.

What's new

This chapter contains an excerpt of the more noteworthy changes.

Across Autoconfigure 1.0.0

A seperate across-autoconfigure artifact has been added that adds Spring Boot autoconfiguration support for many Spring Boot starters. This is the new base dependency for most of your projects and can replace the seperate dependencies to across-core and across-web artifacts.

See the across-autoconfigure documentation section for more information.

Across Core 3.0.0

• better support for Spring Boot autoconfiguration
• addition of @ConditionalOnAcrossModule for conditional component creation
• overhaul of the event handling system: the standard Spring Framework @EventListener infrastructure replaces the previous @Event implementation
• better startup failure feedback when running as a SpringApplication
• improved @ModuleConfiguration support
• @InstallerMethod now supports method arguments which will be autowired when executing the method

Across Web 3.0.0

• major internal refactoring - Spring MVC configuration is now based on the Spring Boot autoconfiguration classes
• several improvements have been made to the Menu building infrastructure
• websocket support is activated automatically if the corresponding libraries are on the classpath

Hibernate JPA module 3.0.0

• internal refactoring - the default configuration now builds on top of Spring Boot JPA support
• the Spring Boot JPA properties are now also supported for configuration and more property configuration options are available
  • when switching from using the Spring Boot JPA starter (now possible with across-autoconfigure), a single AcrossHibernateJpaModule will transparently take over the infrastructure without requiring application changes
• a PlatformTransactionManager is now always created and exposed, along with a TransactionTemplate
• added AcrossHibernateJpaModule.builder() to easily create a module for an additional EntityManager
• it is now possible to add a module extension with an @EntityScan annotation to specify where to scan for entities

Spring Security module 3.0.1

• internal refactoring to re-use the Spring Boot auto-configuration security classes
• WebSecurityConfigurer beans from other modules are now directly supported instead of the Across specific SpringSecurityWebConfigurer
• the default Spring Boot security configuration is applied with some minor changes
  • basic authentication for an application can be configured using the Spring Boot properties (it is not active by default)

Admin Web 3.0.1

The EntityAdminMenu and EntityAdminMenuEvent types have been deprecated. The new equivalent types in EntityModule should be used instead.

Bootstrap UI 2.0.1

• TooltipViewElement has been added to quickly generate a tooltip icon with a corresponding message
• a FormGroupElement now supports a description, a help block and a tooltip
• added support for Java 8 date/time types on DateTimeFormElement

EntityModule 3.0.1

• the module dependencies have been optimized: EntityModule can now be used without AdminWebModule or BootstrapUiModule
  • the corresponding features are simply disabled when either of the modules is missing
• new message codes for adding a tooltip or a help block to a form group
• it is now possible to configure default view element modes on an EntityConfiguration
  • these will determine the default behaviour if none is specified on a property level
• added EntityViewCustomizers to help customizing entity view configuration in a more fluent fashion
  • added helpers for registering an admin menu item or an access validator for a custom view
• added the ExtensionViewProcessorAdapter base class for easily creating a view for a custom extension class
• you can now manually force a property to show as required
• the EntityLinkBuilder has been deprecated in favour of a central EntityViewLinks component with a new EntityViewLinkBuilder
  • the new components make it much easier to create (customized) links to entity views

User module 3.0.0

Compatibility updates for the updated SpringSecurityModule.

Access Control module 3.0.1

• a single AclPermissionFactory is now used which makes it easier for modules to register custom ACL permissions
• AclPermissionForm infrastructure has been added, allowing a developer to build a UI for updating ACL permissions for an entity
  • this requires EntityModule and AdminWebModule to be active in your application

Web CMS 0.0.4

Compatibility updates with changes in Across 3.0.0 and EntityModule 3.0.1.

LDAP module 1.0.1

Minor updates and fixes.
