Spring application.properties
In a Spring Boot application, the application.properties
file is an essential configuration file used to define various settings such as database connection information, server port, logging configuration, and more. This file is typically located in the src/main/resources
directory.
Here are some common configuration items found in the application.properties
file:
1. Database Connection Configuration
Used to configure the details of the data source, such as URL, username, password, and Hibernate dialect for a specific database.
1 | # DataSource Configuration |
2. Server Configuration
Set the server port and context path.
1 | # Server Port |
3. Logging Configuration
Configure the logging level.
1 | # Logging Levels |
4. Spring Boot Specific Configuration
Configure Spring Boot features such as the startup banner.
1 | # Disable Startup Banner |
5. Custom Application Configuration
Define application-specific configurations.
1 | # Custom Application Configuration |
6. Security Configuration
Configure Spring Security related properties.
1 | # Spring Security |
7. Service Discovery and Registration
If your application is part of a microservice architecture and uses a service discovery mechanism.
1 | # Service Registration and Discovery |
8. Message Queue Configuration
Configure message queues (such as RabbitMQ, Kafka) related properties.
1 | # RabbitMQ |
These configuration items are loaded when the application starts and can be accessed in the application using annotations like @Value
or configuration classes.
The actual configuration items will depend on the needs and frameworks used by your application. Spring Boot provides a wide range of configuration options, covering data sources, transaction management, message queues, security settings, custom application parameters, and more.
