Petite

Petite is one great little IoC container and components manager. Petite is easy to use since it requires no external configuration; it is incredibly fast, lightweight and super-small; so anyone can quickly grasp how it works. Petite is quite extensible and open for customization; and non-invasive.
Quick Overview
The following bean shows some basic Petite usage:
1
@PetiteBean
2
public class Foo {
3
​
4
    // dependency injected in the ctor
5
    @PetiteInject
6
    public Foo(ServiceOne one) {...}
7
​
8
    // dependency injected in a field
9
    @PetiteInject("serviceTwo")
10
    ServiceTwo two;
11
​
12
    // dependency injected with the method
13
    @PetiteInject
14
    public void injectService(ServiceThree three) {...}
15
​
16
    // dependency injected with the method
17
    public void injectService(
18
        @PetiteInject ServiceFour four) {...}
19
​
20
    // initialization method
21
    @PetiteInitMethod
22
    public void init() {...}
23
​
24
    public void foo() {
25
    }
26
}

Foo is Petite bean that defines several injection points, for different depending services from the container. Put this bean in the classpath and let PetiteContainer find it and register as a bean. Or register it manually if you like that way more.
Why should I use it?
Petite is one of the lightest Java DI container around. Still, it supports sufficient most of features offered by other containers.
Here are the key features:
property, method and constructor injection points.
Instance life-cycle management, ordered initialization methods.
Adding external objects to container.
Wiring external objects with container's context.
Creating objects by container.
Automatic registration: no XML or code needed, just annotations.
Programmatic configuration: using plain Java.
Scopes: Prototype, Singleton and custom scopes.
Thread local scope for thread singletons.
HTTP session scope for session singletons.
Designed to be extended.
