How to get the value from the URL
问题
我想动态从URL中获取数值。你能帮助实现吗？
请求URL：
requestForm/intakeReqDetails/3210/request
期望响应：
3210
我可以使用子字符串方法来实现这个，但索引号码应该是硬编码的。你能否提供更好的解决方案？
英文:
I want to get the value from the URL dynamically. Could you please help achieve this?
Request URL:
requestForm/intakeReqDetails/3210/request
Expected Reponse:
3210
I can achieve this using the substring method, but the index number should be hardcoded. Can you please get a better solution?

我将完成@Guillaume的回复，他建议使用一个Spring工具类，但在Java中，我们有Class URL，其中包含一些非常好的方法，只需查看获取方法。
或者@Jorn建议如何使用@PathVariable
@GetMapping(path = "/requestForm/intakeReqDetails/{messageId}/request")
public String getInfo(@PathVariable Integer messageId) {
return "message id: " + messageId;
}
英文:
I will complete @Guillaume response, he suggest to use a spring util class but in java we have Class URL with such a great methods, just have a look at get methods.
Or how @Jorn suggest use @PathVariable
@GetMapping(path = "/requestForm/intakeReqDetails/{messageId}/request")
public String getInfo(@PathVariable Integer messageId) {
return "message id: " + messageId;
}
