Spring Framework 4.1 GA 發布

 4.1 幾個主題主要新特性：

• 注釋JMS偵聽器方法
• JCache（JSR-107）的注解全面支持
• 靈活的分辨率和靜態Web資源轉換
• MVC 視圖: declarative resolution, Groovy 標記模板, Jackson的JsonView
• WebSocket的改進： WebSocket scope, SockJS 客戶端支持, WebSocket stats
• 性能: SpEL compiler mode, concurrency fine-tuning across the container

和往常一樣，4.1還附帶了很多改進的細節，例如：

• Direct field binding support with auto-growing for nested fields
• Java 8's Optional for injection points and MVC handler parameters
• Support for the standard @Priority annotation for dependency ordering and selection
• Annotated @Lookup methods with support for provided constructor arguments
• Declarative SQL scripts and programmatic transactions in the TestContext framework
• Enhanced Hibernate JPA setup: isolation levels, discovery of managed packages

Many of those topics have been covered in recent blog posts already and will also be prominently featured at our SpringOne2GX 2014 show in Dallas next week!

We recommend an early upgrade since the 4.1 line is the primary maintenance branch now, immediately superseding the 4.0.x line. For a more conservative upgrade path, we have co-released 4.0.7 with 4.1 GA - as an intermediate step on your way to 4.1 proper.

Cheers,

Juergen
