limited alibaba springboot actual combat

JavaEE Only use Spring It's getting bulky , a large number of XML Files exist in the project , Cumbersome configuration , On the allocation of integrated third party framework , Low development efficiency and deployment efficiency and so on .

Spring Boot Problem solved :

  • Spring Boot Make coding simple

  • Spring Boot Make configuration simple

  • Spring Boot Make deployment simple

  • Spring Boot Make monitoring simple

  • Spring Deficiency

Spring Boot The main features :

  • Use Spring Boot Very little configuration is required , Most of the time we just use the default configuration ;

  • The project is built quickly , Can automatically integrate third-party frameworks without configuration ;

  • You can use it completely XML The configuration file , Just auto configure ( annotation ) and Java Config;

  • Embedded Servlet Containers , Reduced environmental requirements ;

  • Provide starter simplify Manen To configure ,Spring Boot A series of starter pom To simplify our Maven rely on ;

  • Monitoring of application status in operation ;

Why? SpringBoot So popular ?

There may be many reasons , Why? Spring and SpringBoot Very popular , But in my opinion , The main reasons are as follows :

  1. Significantly improve the productivity of developers

SpringBoot The powerful automatic configuration mechanism makes it possible to start using Spring The application is very simple . what's more ,SpringBoot A variety of starters are available , That's enough for many applications . You can create a project , choice Web,Spring Data JPA / Mongo etc. ,H2 / EmbeddedMongo,Spring Data REST Initiator and create your domain entities and repositories to create database supported REST API. this is it , You have a fully functional REST API. This reduces the entry barrier for novices to be familiar with how to manually configure , And it's probably done 100 many times , And tired of writing that template ,SpringBoot It's a good solution to this problem .

  1. Simplify the higher level of abstraction

Spring and SpringBoot One of my main goals is to make things easier .Spring The combination has its own powerful Web MVC frame ,Spring Security frame , But most of its other projects provide a higher level of abstraction , To make them easier to use . for example ,Spring Data JPA By providing API To execute CRUD operation , Sort , Paging without having to implement all of these operations yourself , So that JPA Very easy to use . about Kafka for ,Spring AMQP or Spring Provides a higher level of abstraction , So you can use RabbitMQ or Kafka, Instead of writing low-level boilerplate code .

  1. Micro services and cloud local friendliness

Microservice architecture is the latest hot trend , Many organizations prefer microservice Architecture , And hope to deploy it in AWS,CloudFoundry In the cloud . Usually ,SpringBoot The application is a self-contained deployment unit (FAT Jar) Built , And use its profile concept , We can deploy the same application in multiple environments , Without changing any code . besides ,SpringCloud The module also provides build Cloud Native A set of functions required by microservices .

Because the notes are comprehensive , Quite a lot of content , Here are just some screenshots of the material , If you need to get the “SpringBoot Practical notes ” You can get it at the end of your friend's article .
