Advantage of Spring Boot [closed]

Answer 1

Quoting from the Spring Boot Page, it has following features:

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

Answer 2

In active development,spring boot has the advantage of leave the complex xml file configure.

1.Embedded tomcat discard the web.xml configuration;

2.spring-boot security discard the applicationcontext-security.xml configuration;

3.spring-boot webservice discard the applicationcontext-ws.xml configuration;

4.spring-boot mvc discard the applicationcontext.xml configuration;

5.spring-boot datasource(both Relational Database and nosql Database) discard the applicationcontext.xml configuration,even if more than one datasource.

Discard this configuration file easy our development and improve the efficiency.

Answer 3

Biggest of all is that spring boot is aligned with the concept of microservices and can be run from a container anywhere e.g. cloud. This possible because the following nature of springboot

• small footprint
• standalone services
• easier to launch from a container, each service can be in its own container (like docker)
• easy to configure and deploy completely from a script. Good for auto-scaling and deploying in the cloud.

Answer 4

Advantages of SpringBoot:

• No need of creating boilerplate configuration
• Plenty of SpringBoot Starter to quickly get up and running
• DevTools to autorestart server on code/config updates
• Embedded Tomcat/Jetty/Undertow support
• Easier customization of application properties
• Easy management of profile specific properties
• Easier dependency management using platform-bom

Answer 5

It's real easy to get something going from nothing, with loads of useful defaults.

Not so easy if you want to migrate some existing project which will most likely have developed a lot of quirks that are going to be difficult to migrate.

Answer 6

The big advantage is out of the box configuration based on what it finds and server embedded (you can make a jar run it and go to localhost:8080 to see the result) beside that it has metrics, health checks, externalised configuration, etc.

In my opinion is the perfect tool for building cloud microservices.
