I have controller class Login.Java:

package package com.example.hellospring.controllers;
@RestController  
@RequestMapping("/login")  
public class LoginController {  
    @RequestMapping(method = RequestMethod.POST)  
    public String authenticate(@RequestBody LoginRequest loginRequest) {  
        ...
        return "This is the authentication response.";  
    }  
  
}

And, I have defined a in Filter.java:

package package com.example.hellospring.controllers;
import org.springframework.web.filter.OncePerRequestFilter;  
  
@Component  
public class LoginFilter extends OncePerRequestFilter {  
    @Override  
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {  
        System.out.println("Inside OncePerRequestFilter.LoginFilter: URI: " + request.getRequestURI());  
        if (request.getContentLengthLong() > 100) {  
            ...  
        } else {  
            filterChain.doFilter(request, response);  
        }  
    }  
}

However, my request never reaches my filter, and just processes normally through controller.

While debugging I found that it does steps into public class WebMvcMetricsFilter extends OncePerRequestFilter but not the one that i have defined.

Not sure what am i missing.
