In this short article, we would like to show how to get access to Log4j2 with @Log4j2 Lombok annotation.

Practical example:

xxxxxxxxxx
 
package example.controllers;
​
import lombok.extern.log4j.Log4j2;  // <------ REQUIRED!
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
​
import javax.servlet.http.HttpServletRequest;
​
@Log4j2  // <--------------------------------- REQUIRED!
@Controller
public class ExampleController {
​
    @RequestMapping(value = "/path/to/api", method = RequestMethod.GET)
    @ResponseBody
    public String getIndex(HttpServletRequest request) {
​
        log.info("Logger test...");  // <----- USAGE EXAMPLE!     
​
        return "OK!";
    }
}
