I have followed all the rules in http://docs.oracle.com/javaee/5/api/javax/annotation/PostConstruct.html:
我遵循了http://docs.oracle.com/javaee/5/api/javax/annotation/PostConstruct.html 中的所有规则：
- Only one method can be annotated with this annotation.
- The method MUST NOT have any parameters except in the case of EJB interceptors
- The return type of the method MUST be void.
- The method MUST NOT throw a checked exception.
- The method on which PostConstruct is applied MAY be public, protected, package private or private.
- The method MUST NOT be static .
- 这个注解只能注解一种方法。
- 除 EJB 拦截器外，该方法不得有任何参数
- 方法的返回类型必须是 void。
- 该方法不得抛出已检查的异常。
- 应用 PostConstruct 的方法可以是 public、protected、package private 或 private。
- 该方法不能是静态的。
Any ideas?
有任何想法吗？

If there was no typo, I believe the correct would be
如果没有错别字，我相信正确的应该是
@ComponentScan(basePackages = { "myproject.web"})
since AppComponentFactoryis in myproject.web.factorypackage.
因为AppComponentFactory在myproject.web.factory包里。
