Show log of request and response in Spring Boot

I. Introduction

For you as a backend, writing API is no longer strange. But when it comes to problems, log checking is mandatory and indispensable. With the API, viewing log requests and responses is also a powerful way to help develop investigate the cause of bugs. So in this article, I will guide you to the config project so that the show is the most visible and easy to do log.

II. Installation and demo example

You initialize the spring boot + project and implement some simple API heads as a visual example

1. Configure Spring Boot Application

This is the most basic way to display log requests and responses

You add the following classes to conduct a demo:

Project structure:

RequestLoggingFilterConfig Class:

package com.example.demologging.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;

@Configuration
public class RequestLoggingFilterConfig {

   @Bean
   public CommonsRequestLoggingFilter logFilter() {
       CommonsRequestLoggingFilter filter
               = new CommonsRequestLoggingFilter();
       filter.setIncludeQueryString(true);
       filter.setIncludePayload(true);
       filter.setMaxPayloadLength(10000);
       filter.setIncludeHeaders(false);
       filter.setAfterMessagePrefix("REQUEST DATA : ");
       return filter;
   }
}

package com.example.demologging.config;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.filter.CommonsRequestLoggingFilter;

@Configuration

public class RequestLoggingFilterConfig {

@Bean

public CommonsRequestLoggingFilter logFilter() {

CommonsRequestLoggingFilter filter

= new CommonsRequestLoggingFilter();

filter.setIncludeQueryString(true);

filter.setIncludePayload(true);

filter.setMaxPayloadLength(10000);

filter.setIncludeHeaders(false);

filter.setAfterMessagePrefix("REQUEST DATA : ");

return filter;

}

Class UserController:

package com.example.demologging.controller;

import com.example.demologging.model.UserDto;
import com.example.demologging.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/users")
public class UserController {
   @Autowired
   private UserService userService;

   @GetMapping
   public List&lt;UserDto&gt; getListUser(){
       return userService.getListUser();
   }

}

package com.example.demologging.controller;

import com.example.demologging.model.UserDto;

import com.example.demologging.service.UserService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController

@RequestMapping("/users")

public class UserController {

@Autowired

private UserService userService;

@GetMapping

public List<UserDto> getListUser(){

return userService.getListUser();

}

UserDto Class:

package com.example.demologging.model;

import lombok.AllArgsConstructor;
import lombok.Data;

@Data
@AllArgsConstructor
public class UserDto {
   private String name;
   private String address;
   private int age;
}

package com.example.demologging.model;

import lombok.AllArgsConstructor;

import lombok.Data;

@Data

@AllArgsConstructor

public class UserDto {

private String name;

private String address;

private int age;

}

Class UserService:

package com.example.demologging.service;

import com.example.demologging.model.UserDto;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

@Service
public class UserService {
   public List&lt;UserDto&gt; getListUser(){
       List&lt;UserDto&gt; userDtoList = new ArrayList&lt;&gt;();

       UserDto userDto1 = new UserDto("Nguyen Van A","Ha Noi",18);
       UserDto userDto2 = new UserDto("Nguyen Van B","Ha Noi",19);
       UserDto userDto3 = new UserDto("Nguyen Van C","Ha Noi",20);
       UserDto userDto4 = new UserDto("Nguyen Van D","Ha Noi",18);
       UserDto userDto5 = new UserDto("Nguyen Van E","Ha Noi",19);

       userDtoList.add(userDto1);
       userDtoList.add(userDto2);
       userDtoList.add(userDto3);
       userDtoList.add(userDto4);
       userDtoList.add(userDto5);
       return userDtoList;
   }
}

package com.example.demologging.service;

import com.example.demologging.model.UserDto;

import org.springframework.stereotype.Service;

import java.util.ArrayList;

import java.util.List;

@Service

public class UserService {

public List<UserDto> getListUser(){

List<UserDto> userDtoList = new ArrayList<>();

UserDto userDto1 = new UserDto("Nguyen Van A","Ha Noi",18);

UserDto userDto2 = new UserDto("Nguyen Van B","Ha Noi",19);

UserDto userDto3 = new UserDto("Nguyen Van C","Ha Noi",20);

UserDto userDto4 = new UserDto("Nguyen Van D","Ha Noi",18);

UserDto userDto5 = new UserDto("Nguyen Van E","Ha Noi",19);

userDtoList.add(userDto1);

userDtoList.add(userDto2);

userDtoList.add(userDto3);

userDtoList.add(userDto4);

userDtoList.add(userDto5);

return userDtoList;

}

DemoLoggingApplication Class:

package com.example.demologging;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoLoggingApplication {

   public static void main(String[] args) {
       SpringApplication.run(DemoLoggingApplication.class, args);
   }

}

package com.example.demologging;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class DemoLoggingApplication {

public static void main(String[] args) {

SpringApplication.run(DemoLoggingApplication.class, args);

}

File application.properties:

You use postman to check the API and show log:

Observing the console log in the IDE will see that the log is displayed with all requests and responses:

But you notice the requests and responses have not been “beautiful” and very detailed. So I will go to part 2 to create a full log and more favorable offline.

2. Customize the Log show with Controller Advice

You add the following class:

*** Class CustomURLFilter: ***

package com.example.demologging.config;

import lombok.extern.slf4j.Slf4j;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;

   private static final String REQUEST_ID = "request_id";

   @Override
   public void init(FilterConfig filterConfig) throws ServletException {

   }

   @Override
   public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

       String requestId = UUID.randomUUID().toString();
       servletRequest.setAttribute(REQUEST_ID, requestId);
       logRequest((HttpServletRequest) servletRequest, requestId);
       filterChain.doFilter(servletRequest, servletResponse);
   }

   @Override
   public void destroy() {

   }

   private void logRequest(HttpServletRequest request, String requestId) {
       if (request != null) {
           StringBuilder data = new StringBuilder();
           data.append("nLOGGING REQUEST-----------------------------------n")
                   .append("[REQUEST-ID]: ").append(requestId).append("n")
                   .append("[PATH]: ").append(request.getRequestURI()).append("n")
                   .append("[QUERIES]: ").append(request.getQueryString()).append("n")
                   .append("[HEADERS]: ").append("n");

           Enumeration headerNames = request.getHeaderNames();
           while (headerNames.hasMoreElements()) {
               String key = (String) headerNames.nextElement();
               String value = request.getHeader(key);
               data.append("---").append(key).append(" : ").append(value).append("n");
           }

           log.info(data.toString());
       }
   }
}

}

@Override

private void logRequest(HttpServletRequest request, String requestId) {

if (request != null) {

StringBuilder data = new StringBuilder();

data.append("nLOGGING REQUEST-----------------------------------n")

.append("[REQUEST-ID]: ").append(requestId).append("n")
