我有一个简单的渴望应用程序范围的JSFbean：
@ManagedBean(eager = true, name = "SetupBean")
@ApplicationScoped
public class SetupBean {
@ManagedProperty(value = "#{myBean}")
private MyBean myBean;
public void setMyBean(final MyBean myBean) {
this.myBean = myBean;
}
@PostConstruct
public void postConstruct() {
System.err.println("I'm here!");
}
}
虽然@ManagedProperty行被注释掉了(没有依赖注入)，但一切都"正常"(除了例外，我不能在该bean中做任何有用的事情)。
然而，在取消注释后，我得到了错误：
java.lang.UnsupportedOperationException：在启动期间不支持此方法
不幸的是，我找不到任何有用的信息，在启动过程中不支持WHAT方法。我只知道依赖项注入有问题。MyBean没有什么特别的，它是应用程序范围的，它没有依赖关系，它只有一些私有属性，需要为每个应用程序配置(bean在共享库中)。
这是完整的堆栈跟踪：

这个错误是什么意思？需要做些什么才能进行依赖项注入工作？

渴望申请。强制它先加载。删除急切的，似乎其他人也有类似的错误Eagle ApplicationScoped托管的bean多次构建
某些注释存在重复的包。凸轮。他们是正确的
