Spring MVC之@RequestMapping基本用法

標籤：expr   das   print   value   表達   regular   people   size   color   

 

1、方法層級上的應用：

1 @RequestMapping(value="/department")2 3 　　public String simpleDapatment(){4 5 　　　　system.out.println("");6 　　　　return ("result");7 } 

 

訪問 http://localhost/XXXX/department 時，調用simpledepatment方法。

2、參數綁定

@RequestMapping(value="/department")public String findDepartment(@RequestParaam(departmentId) String departmentId){System.out.println("asasadas");return ("someResult");}

　　

訪問http://localhost/XXXX/department?departmentId=22 就可以出發findDepartmentf方法。

3、REST 風格的參數

1 @RequestMapping(value="/department/{departmentId}")2 3 public String find(@PathVariable String departmentId){4 5 　　system.out.println("asa");6 7 　　return "someRequest";8 9 }

 

訪問http://localhost/XXXX/department/22 ,@PathVariable 接收REST風格的參數

4、REST 風格的參數2

 1 @RequestMapping(value="/department/{depatmentId}") 2  3 public String findDepartment(@PathVariable(departmentId) String somedepartmentId) 4  5 { 6  7 syso; 8  9 retrrn "sds";10 11 }

 

訪問http://localhost/XXXX/department/22 ,不同的是，22被傳到departmentId,但在實際的方法findDepartment(@PathVariable(departmentId) String someDepartment)中，

將其綁定為someDepartment ,所以someDepartment 是22.

5、 URL綁定多個ID

 1 @RequestMapping(value="/user/{userId}/admin/{adminId}") 2  3 public String findPeople( 4  5 　　@PathVariable String userId, 6  7 　　@PathVariable String adminId){ 8  9 Syso("userId+adminId");10 11 return "sdfs";12 13 }

 

6、支援Regex

@RequestMapping(value="/{textualPart:[a-z-]+}.{numericPart:[\\d]+}")  public String regularExpression(    @PathVariable String textualPart,    @PathVariable String numericPart){        System.out.println("Textual part: " + textualPart +         ", numeric part: " + numericPart);      return "someResult";  }  

 

比如如下的URL：/sometext.123，則輸出： 
Textual part: sometext, numeric part: 123.
