reasons to choose Spring Boot
Spring Boot is a widely adopted framework for developing microservices due to its simplicity, flexibility, and robust feature set. Here are some of the major reasons to choose Spring Boot for microservices development:
Table of Contents
1. Auto-Configuration:
Spring Boot’s auto-configuration feature automatically configures your application based on the dependencies you have added, reducing boilerplate code and simplifying configuration.
```java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
2. Embedded Servers:
Spring Boot applications can run independently using embedded servers such as Tomcat, Jetty, or Undertow, eliminating the need for deploying WAR files to external servers.
```java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
3. Microservices Support:
Spring Boot provides various components and libraries specifically designed for building microservices, such as Spring Cloud for service discovery, configuration management, and load
```java
@EnableEurekaClient
@SpringBootApplication
public class ServiceDiscoveryApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceDiscoveryApplication.class, args);
}
}
```
4. Externalized Configuration:
Spring Boot supports externalized configuration, allowing you to manage application properties outside the code, which is essential for microservices running in different environments.
```yaml
# application.yml
server:
port: 8080
spring:
datasource:
url: jdbc:mysql://localhost:3306/mydb
username: user
password: password
```
5. Health Monitoring:
Spring Boot Actuator provides endpoints for monitoring and managing your application, such as health checks, metrics, and environment information.
```java
@RestController
public class HealthController {
@GetMapping("/health")
public String health() {
return "UP";
}
}
```
6. Spring Cloud Integration:
Spring Boot seamlessly integrates with Spring Cloud, which offers tools for service discovery, load balancing, configuration management, and circuit breakers, making it easier to build and manage microservices.
```java
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
```
7. Developer Productivity:
Spring Boot’s convention-over-configuration approach, along with tools like Spring Initializr and Spring Boot CLI, boosts developer productivity by simplifying project setup and development.
```shell
spring init --dependencies=web,data-jpa my-project
cd my-project
./mvnw spring-boot:run
```
8. Community and Documentation:
Spring Boot has a large, active community and extensive documentation, providing ample resources and support for developers.
Example
Extensive documentation and community support available on the official [Spring Boot Documentation](https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/) and [Spring Community](https://spring.io/community).
