In CDI 1.2, section 6.5.3,
The container must ensure that every injection point of type InjectionPoint and qualifier
@Default of any dependent object instantiated during this process receives:
• a null value if it is not being injected into any injection point.
The above is not working on weld 2.2.5. I created a test for this and confirmed that I got a not null injection point.
======================
public class CDIBean2 {
private String data;
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
}
======================
public class CDIBean {
CDIBean2 beanManagerInstance;
public CDIBean(BeanManager manager){
Set<Bean<?>> beanList = manager.getBeans(CDIBean2.class);
if (beanList!=null && !beanList.isEmpty()){
Bean<?> bean = beanList.iterator().next();
CreationalContext<?> context = manager.createCreationalContext(bean);
beanManagerInstance = (CDIBean2) manager.getReference(bean, CDIBean2.class, context);
}
}
public String getData() {
return beanManagerInstance.getData();
}
public void setData(String data) {
beanManagerInstance.setData(data);
}
==========================================
public class CDIBean2Producer {
@Produces
public CDIBean2 produce(InjectionPoint ip){
if(ip != null){
throw new RuntimeException("InjectionPoint exists when producing CDIBean2");
}
return new CDIBean2();
}
}
===================================
@WebServlet("/ProducerNullIPServlet")
public class TestServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
@Inject
private CDIBean bean;
@Inject
private BeanManager manager;
@Inject
private Instance<AnotherBean> anotherBeanInstance;
//@Override
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
doPost(req, resp);
}
//@Override
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
PrintWriter out = resp.getWriter();
Set<Bean<?>> beanList = manager.getBeans(CDIBean2.class);
if (beanList != null && !beanList.isEmpty()) {
Bean<?> bean = beanList.iterator().next();
CreationalContext<?> context = manager.createCreationalContext(bean);
CDIBean2 beanManagerInstance = (CDIBean2) manager.getReference(bean, CDIBean2.class, context);
beanManagerInstance.setData("Test2");
}
out.println("Test Sucessful!");
}
}
The injection point I got in @Produces
public CDIBean2 produce(InjectionPoint ip){..} refers to the @Inject
private CDIBean bean, which is incorrect.
