繼續整理，這個是前段時間用jsp開發的一個站點，說起來php程序員去做jsp程序確實有些小不適應，但是弄完後絕對對於這種強類型語言而比收獲還是頗多的。
1,最基本的，方法級別上應用
@RequestMapping(value="/departments")
public String simplePattern(){
System.out.println("simplePattern method was called");
return "someResult";
}
則訪問http://localhost/xxxx/departments的時候，會調用 simplePattern方法了
2, 參數綁定
@RequestMapping(value="/departments")
public String findDepatment(
@RequestParam("departmentId") String departmentId){
System.out.println("Find department with ID: " + departmentId);
return "someResult";
}
形如這樣的訪問形式：
/departments?departmentId=23就可以觸發訪問findDepatment方法了
3, REST風格的參數
@RequestMapping(value="/departments/{departmentId}")
public String findDepatment(@PathVariable String departmentId){
System.out.println("Find department with ID: " + departmentId);
return "someResult";
}
形如REST風格的地址訪問，比如：
/departments/23，其中用(@PathVariable接收rest風格的參數
4,REST風格的參數綁定形式之2
先看例子，這個有點象之前的：
@RequestMapping(value="/departments/{departmentId}")
public String findDepatmentAlternative(
@PathVariable("departmentId") String someDepartmentId){
System.out.println("Find department with ID: " + someDepartmentId);
return "someResult";
}
這個有點不同，就是接收形如/departments/23的URL訪問，把23作為傳入的departmetnId,，但是在實際的方法findDepatmentAlternative中，使用
@PathVariable("departmentId") String someDepartmentId，將其綁定為
someDepartmentId,所以這裡someDepartmentId為23
5, url中同時綁定多個id
@RequestMapping(value="/departments/{departmentId}/employees/{employeeId}")
public String findEmployee(
@PathVariable String departmentId,
@PathVariable String employeeId){
System.out.println("Find employee with ID: " + employeeId +
" from department: " + departmentId);
return "someResult";
}
這個其實也比較好理解了。
6, 支持正則表達式
@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，則輸出：
Textual part: sometext, numeric part: 123.
