What are the advantages of spring boot application?

Spring boot provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration).

Advantages of spring boot application

1.    Create stand-alone Spring applications
2.     Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
3.     Provide opinionated 'starter' POMs to simplify your Maven configuration
4.     Automatically configure Spring whenever possible
5.     Provide production-ready features such as metrics, health checks and externalized configuration
6.     Absolutely no code generation and no requirement for XML configuration
7.     No need of creating boilerplate configuration
8.     Plenty of SpringBoot Starter to quickly get up and running
9.     DevTools to autorestart server on code/config updates
10.     Easier customization of application properties
11.     Easy management of profile specific properties
12.     Easier dependency management using platform-bom
13.     Embedded tomcat discard the web.xml configuration;
14.     spring-boot security discard the applicationcontext-security.xml configuration;
15.     spring-boot webservice discard the applicationcontext-ws.xml configuration;
16.     spring-boot mvc discard the applicationcontext.xml configuration;
17.     spring-boot datasource(both Relational Database and nosql Database) discard the applicationcontext.xml configuration,even if more than one datasource.
18.     Provide a radically faster and widely accessible getting started experience for all Spring development.
