You may recall that inside the microcontainer each bean is represented by a context which holds amongst other things the bean's current state. This context information can be injected into bean properties or constructor/factory-method parameters using the @Inject annotation or <inject> element together with a fromContext attribute.
@Inject(bean="otherBean",
fromContext="beanInfo")
public void setBeanInfo(BeanInfo beanInfo) {
...
}
<bean name="sndBean" class="org.jboss.test.NameAwareBean">
<property name="beaninfo">
<inject bean="otherBean" fromContext="beaninfo"/>
</property>
</bean>
If you want to inject information about the current bean's context then you can simply omit the bean attribute.
@Inject(fromContext="beanInfo")
public void setBeanInfo(BeanInfo beanInfo) {
...
}
<bean name="sndBean" class="org.jboss.test.NameAwareBean">
<property name="beaninfo">
<inject fromContext="beaninfo"/>
</property>
</bean>
The fromContext attribute can take the following values:
name - the name of the bean
aliases - a list of the bean's other names
metadata - information about the bean from annotations or deployment descriptors
beaninfo - information about the bean from the bean class
scope - the microcontainer scope that the bean belongs to
id - the internal id of the bean within the microcontainer
context - the bean context
All context information is wrapped into unmodifiable objects to prevent the user from changing anything outside of the microcontainer's control.
