在傳統的開發過程中，我們的控制CONTROLL層通常需要轉向一個JSP視圖；但隨著WEB2.0相關技術的崛起，我們很多時候只需要返回數據即可，而不是一個JSP頁面。
?
SPRING MVC3的@ResponseBody使Controller直接返回數據，而不是直接指向具體的視圖；同時通過
MessageConverter和produces（如produces="text/plain;charset=UTF-8"）可以返回各種格式的數據（XML，json，RSS，TEXT，字節流等),本章只介紹最簡單的使用；
見代碼：
@ResponseBody可以直接返回結果，
而ResponseEntity?可以定義返回的HttpHeaders和HttpStatus，見文章最后的兩張圖
