Provide opinionated 'starter' dependencies to simplify your build configuration
Automatically configure Spring and 3rd party libraries whenever possible
Provide production-ready features such as metrics, health checks and externalized configuration
Absolutely no code generation and no requirement for XML configurationSpring Boot - Advantages of spring boot application
No need of creating boilerplate configuration
Plenty of SpringBoot Starter to quickly get up and running
DevTools to autorestart server on code/config updates
Easier customization of application properties
Easy management of profile specific properties

spring-boot security discard the applicationcontext-security.xml configuration;
spring-boot webservice discard the applicationcontext-ws.xml configuration;
spring-boot mvc discard the applicationcontext.xml configuration;
spring-boot datasource(both Relational Database and nosql Database) discard the applicationcontext.xml configuration,even if more than one datasource.
