SpringMVC中@ResourceMapping的基本用法

最近从Struts转投SpringMVC，看代码时发现这个注解，感觉其作用应该和Struts的action差不多，把用法记录下来。
1.
@RequestMapping(value="/departments")public String simplePattern(){ System.out.println("simplePattern method was called"); return "someResult"; }//访问http://localhost/xxxx/departments的时候，会调用implePattern方法了
2.
@RequestMapping(value="/departments")public String findDepatment( @RequestParam("departmentId") String departmentId){ System.out.println("Find department with ID: " + departmentId); return "someResult"; } //形如这样的访问形式： /departments?departmentId=23就可以触发访问findDepatment方法了
3.
@RequestMapping(value="/departments/{departmentId}")public String findDepatment(@PathVariable String departmentId){ System.out.println("Find department with ID: " + departmentId); return "someResult"; } // 形如REST风格的地址访问，比如 /departments/23，其中用(@PathVariable接收rest风格的参数
4.
@RequestMapping(value="/departments/{departmentId}")public String findDepatmentAlternative( @PathVariable("departmentId") String someDepartmentId){ System.out.println("Find department with ID: " + someDepartmentId); return "someResult"; } // 这个有点不同，就是接收形如/departments/23的URL访问，把23作为传入的departmetnId,，但是在实际的方法findDepatmentAlternative中，使用
// @PathVariable("departmentId") String someDepartmentId，将其绑定为someDepartmentId,所以这里someDepartmentId为23
5.
@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"; }//绑定多个参数
6.
@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";} //正则表达式 比如如下的URL：/sometext.123，则输出： Textual part: sometext, numeric part: 123.
