英文:
Log url to Spring controller from inside it
问题
假设您有一个类似于以下代码的 Spring MVC 控制器：
@Controller
public class RestController {
@GetMapping(value = "/test")
public @ResponseBody Test getTestData(...) {
// console log path to controller: http://localhost:80/app/test
return testData;
}
}
在控制器内部是否有可能从中记录/打印出 URL？在上面的示例中，输出可能类似于 https://localhost:80/app/test。
但是，使用 servlet 的 .getRequestUrl 并不能正常工作。

Suppose you have a Spring MVC controller, something like this
@Controller
public class RestController {
@GetMapping(value = "/test")
public @ResponseBody Test getTestData(...) {
// console log path to controller: http://localhost:80/app/test
return testData;
}
}
Is it possible to log/print from inside the controller the url to it? In the example above the output would be something like https://localhost:80/app/test
Using .getRequestUrl from the servlet is not behaving correctly.

You can inject UriComponentsBuilder as a parameter and then use the method toUriString(). From the documentation, it is used to build a relative URI from the current request's context. This should work as expected Doc.
@Controller
public class RestController {
...
@GetMapping(value = "/test")
public @ResponseBody Test getTestData(UriComponentsBuilder ucb, ...) {
LOGGER.debug(ucb.toUriString());
// console log path to controller: http://localhost:80/app/test
return testData;
}
...
}
