如何用Spring Data Rest截取GET调用？

import org.springframework.data.rest.core.annotation.HandleBeforeGet;
import org.springframework.data.rest.core.annotation.RepositoryEventHandler;
import org.springframework.stereotype.Component;

@Component
@RepositoryEventHandler
public class ResourceEventHandler {

    @HandleBeforeGet
    public void handleBeforeGet(Object resource) {
        // 在这里处理 GET 调用之前的逻辑
        System.out.println("Handling GET request for resource: " + resource);
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/custom")
public class CustomController {

    @Autowired
    private MyRepository repository;

    @GetMapping("/resources/{id}")
    public Object getResource(@PathVariable Long id) {
        // 在这里处理 GET 请求
        System.out.println("Handling GET request for resource with id: " + id);
        return repository.findById(id).orElse(null);
    }
}

import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;

@ControllerAdvice
public class GlobalControllerAdvice {

    @ExceptionHandler(ResourceNotFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public void handleResourceNotFoundException(ResourceNotFoundException ex) {
        // 在这里处理 GET 请求异常
        System.out.println("Resource not found: " + ex.getMessage());
    }
}
