# Java Logger Intro [![Gayanuka Bulegoda][grb-shield]][grb-url]
This project demonstrates Java's built-in logger capabilities through a simple Spring Boot REST controller. It serves as a practical example for configuring and using various logging levels within a Spring Boot application.
## Overview
The Java Logger Intro Sample project is designed to help developers understand how to implement and configure Java’s inbuilt logging framework within a Spring Boot environment. It illustrates the usage of multiple logging levels to provide insights into system operations, warnings, errors, and detailed debugging information.
## Features
- **Spring Boot REST Controller**: Provides an endpoint to trigger logging.
- **Multiple Logging Levels**: Demonstrates INFO, WARN, ERROR, FATAL, DEBUG, and TRACE levels.
- **Configurable Logging**: Easy-to-customize logging settings using `application.properties`.
## Prerequisites
- Java JDK 17 or later
- Maven build tool
- Basic understanding of Spring Boot
## Installation
1. **Clone the repository:**
```bash
https://github.com/GRB-Workspace/Java-Logger-Intro.git
```
2. **Navigate to the project directory:**
```bash
cd Java-Logger-Intro
```
3. **Build and run the application:**
```bash
mvn spring-boot:run
```
## Usage
Once the application is running, you can access the sample REST endpoint at:
```bash
http://localhost:8085/log
```
Triggering the endpoint will log messages using the different logging levels as configured.
## Configuration
The logging behavior is controlled through the `application.properties` file. For example, you can adjust the root logging level:
```properties
logging.level.root=INFO
logging.level.com.example=DEBUG
```
Modify these settings to increase or decrease log verbosity as needed.
## Logging Levels
- **INFO**: Logs general system information.
- **WARN**: Logs warnings about non-critical issues.
- **ERROR**: Logs critical errors.
- **FATAL**: Logs fatal errors that may cause the system to crash.
- **DEBUG**: Logs detailed information for debugging purposes.
- **TRACE**: Logs very detailed, step-by-step trace information.
