How do I get the continuation mapping from the URL in a Spring application?
问题
我有这个Spring应用程序，我想从URL中获取值，例如：
发送到Spring应用程序的URL是www.example.com/app/account/register。当我的代码看起来像这样时，我如何获取/account之后的/register部分。
对于这个示例，我使用了/register，但这也可以是/login、/something。
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account")
public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
return true;
}
}

The url send to the spring application is www.example.com/app/account/register. How do I get the /register part after /account when my code looks like this.
For this example I used /register but this can be /login, /something as well.
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account")
public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
return true;
}
}

你可以使用 @PathVariable 注解来获取值。
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account/{operation}")
public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders,
@RequestBody Map<String, String> payLoad,
@PathVariable("operation") String operation){
return true;
}
}
英文:
You can use the @PathVariable annotation to get the value.
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account/{operation}")
public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders,
@RequestBody Map<String, String> payLoad,
@PathVariable("operation") String operation){
return true;
}
}

Use UriComponentsBuilder作为参数，它将由Spring注入并初始化为当前URI。然后，您可以将其转换为UriComponents [UriComponents][1]以查询路径。
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account")
public boolean AccountServer(UriComponentsBuilder builder, @RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
List<String> pathSegments = builder.build().getPathSegments();
...
return true;
}
}

英文:
Use UriComponentsBuilder as a parameter, it will be injected by Spring and initialized with current URI. You can then convert to UriComponents UriComponents to query the path.
@RestController
@RequestMapping("/app")
public class MainController {
@RequestMapping(value = "/account")
public boolean AccountServer(UriComponentsBuilder builder, @RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
List<String> pathSegments = builder.build().getPathSegments();
...
return true;
}
}
