Add Logger in Java

So In Nodejs logger works like this

graph TD
Request --> Express 
Express --> middleware
middleware --> logger 
middleware --> request_handler 
middleware --> data_validator 
middleware --> cors 
middleware --> controller
controller --> service 
service --> controller
controller --> middleware
middleware --> Express
Express --> Request 

Even Working with python I did something like this while I was moving the lambda function code to a flask server in Euler Motors ![[Resume#euler-motors—delhi-india|Euler Motors – Delhi, India]]

According to the official docs of spring boot spring-boot-starter-web solves a lot of problem so let’s try that also this will be our first dependency injection

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>

package in.abhi8290.helloworld;  
  
  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RestController;  
  
// Defining import org.slf4j.LoggerFactory;  
import org.slf4j.Logger;  
  
  
@RestController  
public class HelloController {  
    // Defining  
    private static final Logger logger = LoggerFactory.getLogger(HelloController.class);  
  
    @GetMapping("/")  
    public String hello() {  
  
        logger.info("Wait I have got a new Logger man !!");  
        return "Hello, World!  ";  
    }  
  
    @GetMapping("/v1")  
    public String helloV1() {  
        return "Hello, World2 ";  
    }  
}

This is done : Simpler than Nodejs !!
