New issue 693 by [email protected]: Guice provides different instances
of desired type.
http://code.google.com/p/google-guice/issues/detail?id=693
Code:
===
public static class A {
B b;
C c;
public A() {
System.out.println("A");
}
@Inject
public void setB(B b) {
this.b = b;
}
@Inject
public void setC(C c) {
this.c = c;
}
}
public static class B {
A a;
C c;
public B() {
System.out.println("B");
}
@Inject
public void setA(A a) {
this.a = a;
}
@Inject
public void setC(C c) {
this.c = c;
}
void foo() {
System.out.println(System.identityHashCode(this.c));
System.out.println(System.identityHashCode(this.a.c));
}
}
public static class C {
A a;
B b;
public C() {
System.out.println("C");
}
@Inject
public void setA(A a) {
this.a = a;
}
@Inject
public void setB(B b) {
this.b = b;
}
}
public static void main(String[] args) {
Guice.createInjector(new AbstractModule() {
protected void configure() { }
}).getInstance(B.class).foo();
}
===
Prints:
===
B
A
C
C
A
false
1741825447
363211825
===
It means:
* classes A and B were instantiated twice
* B and A objects have different references to C
