Bean无法访问的方法:
@ManagedBean
@ApplicationScoped
public class AppBean {
@PostConstruct
public void test() {
throw new RuntimeException("test");
}
}
就这样。 有任何想法吗?
如果您的应用程序作用域托管bean未在任何页面上使用,则必须使用它进行注释
@ManagedBean(eager=true)
为了在启动时初始化它。
@PostConstruct应该在加载bean时工作,你可以在直接调用或使用eager = true时加载它,或者在构造函数中执行init。
