# Sentinel vs spring-boot

Sentinel and spring-boot share 5 technologies: Spring, JAX-RS, lettuce-core, jakarta.servlet:jakarta.servlet-api, and org.slf4j:slf4j-api. Both are written in Java.

- [alibaba/Sentinel](https://seerepo.com/r/alibaba/Sentinel): A powerful flow control component enabling reliability, resilience and monitoring for microservices. (面向云原生微服务的高可用流控防护组件)
- [spring-projects/spring-boot](https://seerepo.com/r/spring-projects/spring-boot): Spring Boot helps you to create Spring-powered, production-grade applications and services with absolute minimum fuss.

## What they share and what sets them apart

- In common: Spring, JAX-RS, lettuce-core, jakarta.servlet:jakarta.servlet-api, org.slf4j:slf4j-api
- Only in Sentinel: jakarta.enterprise.cdi-api, Quarkus, log4j-core, log4j-slf4j-impl, logback-classic, logback-core, org.apache.logging.log4j:log4j-api
- Only in spring-boot: org.springframework.boot:spring-boot-starter-web, H2 Database, org.springframework.data:spring-data-redis, org.springframework.ldap:spring-ldap-core, JetBrains, tomcat-embed-core, org.eclipse.jetty.compression:jetty-compression-server, org.springframework.data:spring-data-commons, org.hibernate.orm:hibernate-core, spring-security-saml2-service-provider, spring-session-data-redis, org.springframework.session:spring-session-core, angus-mail, jakarta.mail:jakarta.mail-api, Hibernate, io.micrometer:micrometer-core, ch.qos.logback:logback-classic, org.apache.logging.log4j:log4j-core, Apache
