- 4. Spring Boot?Spring Boot? ( ) "Takes an opinionated view of building production-ready Spring applications. Favors convention over con guration and is designed to get you up and running as quickly as possible." https://projects.spring.io/spring-boot
- 5. Key features?Key features? create stand-alone Spring applications embed web server directly (no WAR les) automatic Spring con guration wherever possible no code generation and no XML con guration still offering all Spring features.
- 6. Pros?Pros? no separate web server needed debug your application directly from your IDE deployment by just copying your JAR le(s) no web.xml or con guration classes needed up and running with one Java le and a build script. ( )https://www.ethode.com/blog/6-simple-reasons-why-spring-boot-rocks
- 7. Cons?Cons? custom con guration will be a bit of a puzzle porting your legacy Spring project would be a disaster! it uses Spring, excluding roughly half of the Java community.
