1、方法级别上的应用：
1 @RequestMapping(value="/department")
2
3 public String simpleDapatment(){
4
5 system.out.println("");
6 return ("result");
7 }
访问 http://localhost/XXXX/department 时，调用simpledepatment方法。
2、参数绑定
@RequestMapping(value="/department")
public String findDepartment(@RequestParaam(departmentId) String departmentId){
System.out.println("asasadas");
return ("someResult");
}
访问http://localhost/XXXX/department?departmentId=22 就可以出发findDepartmentf方法。
3、REST 风格的参数
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 }
访问http://localhost/XXXX/department/22 ,@PathVariable 接收REST风格的参数
4、REST 风格的参数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 }
访问http://localhost/XXXX/department/22 ,不同的是，22被传到departmentId,但在实际的方法findDepartment(@PathVariable(departmentId) String someDepartment)中，
将其绑定为someDepartment ,所以someDepartment 是22.
5、 URL绑定多个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、支持正则表达式
@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，则输出：
Textual part: sometext, numeric part: 123.
Spring MVC之@RequestMapping基本用法
