Can I use path variable in spring controller class?
提问by Dilip Kumar
Can I use path variable for spring controller class?
我可以为 spring 控制器类使用路径变量吗？
I know that we can use path variables in controller's methods. In the same fashion can we use it for entire class?
Eg:
我知道我们可以在控制器的方法中使用路径变量。我们可以以同样的方式将它用于整个班级吗？
例如：
@Controller
@RequestMapping(value = "{version}/test")
class TestController {
}
Can we use like this? If yes how do we read {version}variable? Actually i need this kind of approach, based on the version i'll respond. If the above approach is not possible can you please suggest me a design to solve this problem?
我们可以这样使用吗？如果是，我们如何读取{version}变量？实际上我需要这种方法，基于我会回应的版本。如果上述方法不可行，您能否建议我一个设计来解决这个问题？

Yes you can. Just declare it as @PathVariable in your methods if you want to access it there.
是的你可以。如果您想在那里访问它，只需在您的方法中将其声明为 @PathVariable 即可。
@Controller
@RequestMapping(value = "{version}/test")
class TestController {
@RequestMapping(value="/something")
public ModelAndView doSomething(@PathVariable String version) {
// do something here with the version
}
}
