The difference between SSM framework and Spring Boot.

SSM framework refers to the combination of Spring, SpringMVC, and MyBatis, while Spring Boot is a rapid development framework based on the Spring framework.

The main differences are as follows:

1. Architecturally: The SSM framework follows the traditional three-tier architecture, consisting of the presentation layer, business logic layer, and data access layer. On the other hand, Spring Boot is a rapid development framework based on the Spring framework. It offers automatic configuration and a principle of convention over configuration, which simplifies project building and deployment.
2. In terms of configuration: SSM framework requires manual configuration of each component’s dependencies and configuration files, whereas Spring Boot offers automatic configuration, which can configure corresponding components based on the project’s dependencies.
3. Development efficiency is enhanced by Spring Boot’s feature of automatic configuration and convention over configuration, allowing developers to quickly build projects without spending too much time on configuration.
4. Spring Boot offers better support for microservices architecture, including utilizing Spring Cloud for service registration, configuration center, load balancing, and other functionalities.

In general, the SSM framework is a traditional Java development framework that requires manual configuration of each component; while Spring Boot is a rapid development framework that provides automatic configuration and prefers convention over configuration, which can improve development efficiency.
