What is Spring's Minimum Dependencies for Dependency Injection?

问题

What are the minimum dependencies required to just use Spring's dependency injection (core framework only)? I'm using Spring for a standalone application, and I'd like to minimize the number of dependencies that I have to ship with the application.

I suppose I could systematically remove a Jar and see if the application breaks, but it would be much better if someone had a definitive answer.

Oh, and I'm using Spring 2.5.

回答1:

Check out the readme.txt that comes with the download of Spring 2.5.

Assuming you don't have AOP, JDBC, Transactions, or ORM, then your best bet is probably:

spring-core
spring-beans
spring-context

回答2:

If your are using maven then only spring-context is needed in your pom.xml, it depends on aop, beans, core, expression and asm

回答3:

I think for today it is more convenient to use spring-boot, coming out of this idea my suggestion is to use "org.springframework.boot:spring-boot-starter"

below is dependencies tree:

compile - Dependencies for source set 'main' (deprecated, use 'implementation' instead).
