Spring and Spring Boot are both Java frameworks for building enterprise-level applications. Spring is a complete framework that provides various functions, including dependency injection, transaction management, data access, web development, etc. Spring Boot is a Spring-based framework designed to simplify the development and deployment of Spring applications.
The main differences between Spring and Spring Boot are as follows:
Spring is a complete framework that provides various functions. Spring Boot is a Spring-based framework that only provides the most basic functions.
Spring's configuration is more complicated. The configuration of Spring Boot is relatively simple and adopts the principle of convention over configuration.
Spring application deployment is relatively complex. Spring Boot application deployment is relatively simple and can be deployed using the Spring Boot Maven plug-in or the Spring Boot Gradle plug-in.
The following is a comparison table between Spring and Spring Boot:
| Function | Spring | Spring Boot |
|---|---|---|
| Frame size | whole | Based on Spring |
| Function | Provide various functions | Provide the most basic functions |
| Configuration | quite complicated | easier |
| Application deployment | quite complicated | easier |
Spring Boot is a subset of Spring that provides the core functionality of Spring and provides some additional features to simplify the development and deployment of Spring applications.
Spring Boot is suitable for the following scenarios:
Scenarios that require rapid development of Spring applications
Scenarios where Spring application deployment needs to be simplified
If you need a complete framework, you can use Spring. If you need a simple framework, you can use Spring Boot.
