What are the advantages and disadvantages of SpringBoot and Spring?

Comparison between SpringBoot and Spring

Analysis of the advantages and disadvantages of the original Spring

1. Analysis of the advantages of Spring

Spring is a lightweight replacement for Java Enterprise Edition (JEE, also known as J2EE). There is no need to develop heavyweight EnterpriseJavaBean (EJB). Spring provides a relatively simple method for enterprise-level Java development. Through dependency injection and aspect-oriented programming, EJB is implemented with simple Java objects (Plain Old Java Object, POJO). Function.

2. Analysis of Spring's shortcomings

Although Spring's component code is lightweight, its configuration is heavyweight. In the beginning, Spring used XML configuration, and a lot of XML configuration. Spring 2.5 introduces annotation-based component scanning, which eliminates a lot of explicit XML configuration for the application's own components. Spring 3.0 introduces Java-based configuration, a type-safe, reconfigurable alternative to XML.

All these configurations represent development losses. Because of the need to switch between thinking about Spring feature configuration and solving business problems, writing configuration takes time away from writing application logic. Like all frameworks, Spring is practical, but at the same time it demands a lot in return.

In addition, project dependency management is also a time-consuming and labor-intensive matter. When setting up the environment, it is necessary to analyze the coordinates of which libraries are to be imported, and also the coordinates of other libraries that are dependent on it. Once the wrong dependent version is selected, the ensuing incompatibility problems will seriously hinder The development progress of the project.

Overview of SpringBoot

1.SpringBoot solves the above shortcomings of Spring

SpringBoot improves and optimizes the above shortcomings of Spring, based on the agreed advantages The idea of ​​​​focusing on configuration allows developers to not have to switch their thinking between configuration and logical business, but to devote themselves wholeheartedly to writing code for logical business, thereby greatly improving development efficiency and shortening the project cycle to a certain extent.

2. Features of SpringBoot

Provides a faster entry experience for Spring-based development out of the box, with no code generation and no XML configuration. At the same time, the default values ​​can also be modified to meet specific needs. It provides some non-functional features common in large projects, such as embedded servers, security, indicators, health detection, external configuration, etc. SpringBoot is not an enhancement of Spring functions; Provides a quick way to use Spring.

Core functions of SpringBoot

1. Starting dependency

Starting dependency is essentially a Maven Project Object Model (POM), Defines transitive dependencies on other libraries, which together support a certain function. Simply put, the starting dependency is to package coordinates with certain functions together and provide some default functions.

2. Automatic configuration

Spring Boot’s automatic configuration is a runtime (more precisely, when the application starts) process, taking into account many factors , to decide which Spring configuration should be used and which one should not be used. This process is completed automatically by Spring.
