小脚印依赖注入java

Question

I am looking for a very lightweight dependency injection framework for java. With minimum possible dependencies and minimum features.

Just something along the following lines: receive a java.util.List of Class es, instantiate them and just auto-wire all the objects one into the other.

Answer 1

I would recommend Spring , since this can provide a small footprint when using only the core packages.

If you think Spring is overkill, then perhaps PicoContainer , or guice ?

Answer 2

也许你应该看一下Google Guice： http ： //code.google.com/p/google-guice/

Answer 3

Silk DI is about 120K single jar file with no further runtime dependencies. It has a fluent binder interface like guice but is more flexible and allows to remove features you don't like. Eg Collection or List injection can be added in a one liner .

Answer 4

I have been trying MentaContainer for less than a week now and I am satisfied by its clean and straightforward API. Instead of using XML or Annotations for the setup it uses a fluent API almost like a DSL which for me felt like like heaven because I am using it to build a small web container with IoC support. It provides a THREAD scope for the components which fits perfectly for the REQUEST scope of the web container. It is very lightweight so it may be what you need.

Answer 5

Definitely look into Guice. Been using it for a year, and absolutely love it.

Answer 6

Take a look at dagger2, developped at google (forked of square's dagger1), for only 17kb jar.

• Much less boilerplate than guice
• compile time verification of injection (with explicit error message. That's something spring, guice does definitly not)
• generate Facotries, codes upon compile. Very powerfull
