@RequestMapping:

      

      常用方法：method=RequestMethod.GET/method=RequestMethod.POST

      RequestMapping中限定請求引數對映：params

@RequestMapping(value="/testParams",params={"email","tel!=110"},method=RequestMethod.GET)
 public String testParams()
 {
   System.out.println("=====testParams");
   return "ok";
 }

 

   RequestMapping中限定請求頭對映：headers

@RequestMapping(value="/testHeaders",headers={"Host=localhost:8081"},method=RequestMethod.GET)
 public String testHeaders()
 { 
   System.out.println("=====testHeaders");
   return "ok";
 }

 URL路徑對映
           1. HTTP協議檢視
           2.普通URL對映
           3. Ant風格URL對映(?  匹配一個字元  *  匹配零個或多個字元 ** 匹配零個或多個路徑)

@RequestMapping(value="/testAntStyle**/**/q",method=RequestMethod.GET)
@RequestMapping(value="/testAntStyle??",method=RequestMethod.GET)
@RequestMapping(value="/testAntStyle*",method=RequestMethod.GET)
 public String testAntStyle()
 {
  System.out.println("=====testAntStyle");
   return "ok";
 }

           

[email protected]佔位符URL對映
                  @RequestMapping(value="/users/{userId}")
                  @RequestMapping(value=“/users/{userId}/create”)
                  @RequestMapping(value="/users/{userId}/topics/{topicId}")
                  @PathVariable可以提取URI模板模式中的{×××}中的×××變數。

REST風格:

（1）每一個URI代表一種資源；
（2）客戶端和伺服器之間，傳遞這種資源的某種表現層；
（3）客戶端通過四個HTTP動詞，對伺服器端資源進行操作，實現"表現層狀態轉化"。

增-POST
    method=RequestMethod.POST
刪-DELETE
    method=RequestMethod.DELETE
改-PUT
    method=RequestMethod.PUT
查-GET
    method=RequestMethod.GET

Restful適配
  web.xml裡配置過濾器 HiddenHttpMethodFilter

 <!-- 配置org.springframework.web.filter.HiddenHttpMethodFilter，實現POST轉換為PUT、DELETE -->
 <filter>
   <filter-name>HiddenHttpMethodFilter</filter-name>
   <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
 </filter>
 <filter-mapping>
   <filter-name>HiddenHttpMethodFilter</filter-name>
   <url-pattern>/*</url-pattern>
 </filter-mapping> 

   _method的隱藏域

Delete

<form action="${pageContext.request.contextPath}/order/38" method="post">
 <input type="hidden" name="_method" value="DELETE">
 <input type="submit" value="Delete_commit">
</form>

Put

<form action="${pageContext.request.contextPath}/order/38" method="post">
 <input type="hidden" name="_method" value="PUT">
 <input type="submit" value="Update_commit">
</form>
