Core Container Improvements General Web Improvements
3.4 Java EE 6 and 7
Java EE version 6 or above is now considered the baseline for Spring Framework 4, with the JPA 2.0 and Servlet 3.0 specifications being of particular relevance. In order to remain compatible with Google App Engine and older application servers, it is possible to deploy a Spring 4 application into a Servlet 2.5 environment. However, Servlet 3.0+ is strongly recommended and a prerequisite in Spring’s test and mock packages for test setups in development environments. Note If you are a WebSphere 7 user, be sure to install the JPA 2.0 feature pack. On WebLogic 10.3.4 or higher, install the JPA 2.0 patch that comes with it. This turns both of those server generations into Spring 4 compatible deployment environments. On a more forward-looking note, Spring Framework 4.0 supports the Java EE 7 level of applicable specifications now: in particular, JMS 2.0, JTA 1.2, JPA 2.1, Bean Validation 1.1, and JSR-236 Concurrency Utilities. As usual, this support focuses on individual use of those specifications, e.g. on Tomcat or in standalone environments. However, it works equally well when a Spring application is deployed to a Java EE 7 server. Note that Hibernate 4.3 is a JPA 2.1 provider and therefore only supported as of Spring Framework 4.0. The same applies to Hibernate Validator 5.0 as a Bean Validation 1.1 provider. Neither of the two are officially supported with Spring Framework 3.2.3.5 Groovy Bean Definition DSL
Beginning with Spring Framework 4.0, it is possible to define external bean configuration using a Groovy DSL. This is similar in concept to using XML bean definitions but allows for a more concise syntax. Using Groovy also allows you to easily embed bean definitions directly in your bootstrap code. For example: def reader = new GroovyBeanDefinitionReadermyApplicationContext reader.beans { dataSourceBasicDataSource { driverClassName = org.hsqldb.jdbcDriver url = jdbc:hsqldb:mem:grailsDB username = sa password = settings = [mynew: setting ] } sessionFactorySessionFactory { dataSource = dataSource } myServiceMyService { nestedBean = { AnotherBean bean - dataSource = dataSource } } } For more information consult the GroovyBeanDefinitionReader javadocs .3.6 Core Container Improvements
There have been several general improvements to the core container: 4.3.9.RELEASE Spring Framework 21 • Spring now treats generic types as a form of qualifier when injecting Beans. For example, if you are using a Spring Data Repository you can now easily inject a specific implementation: Autowired RepositoryCustomer customerRepository . • If you use Spring’s meta-annotation support, you can now develop custom annotations that expose specific attributes from the source annotation . • Beans can now be ordered when they are autowired into lists and arrays . Both the Order annotation and Ordered interface are supported. • The Lazy annotation can now be used on injection points, as well as on Bean definitions. • The Description annotation has been introduced for developers using Java-based configuration. • A generalized model for conditionally filtering beans has been added via the Conditional annotation. This is similar to Profile support but allows for user-defined strategies to be developed programmatically. • CGLIB-based proxy classes no longer require a default constructor. Support is provided via the objenesis library which is repackaged inline and distributed as part of the Spring Framework. With this strategy, no constructor at all is being invoked for proxy instances anymore. • There is managed time zone support across the framework now, e.g. on LocaleContext .3.7 General Web Improvements
Deployment to Servlet 2.5 servers remains an option, but Spring Framework 4.0 is now focused primarily on Servlet 3.0+ environments. If you are using the Spring MVC Test Framework you will need to ensure that a Servlet 3.0 compatible JAR is in your test classpath. In addition to the WebSocket support mentioned later, the following general improvements have been made to Spring’s Web modules: • You can use the new RestController annotation with Spring MVC applications, removing the need to add ResponseBody to each of your RequestMapping methods. • The AsyncRestTemplate class has been added, allowing non-blocking asynchronous support when developing REST clients. • Spring now offers comprehensive timezone support when developing Spring MVC applications.3.8 WebSocket, SockJS, and STOMP Messaging
