席位——列出所有组成部分
原标题:Seam - list all components

  • seam

我希望得到一份所有组成部分的清单,以便我能够进一步处理这些内容。 如果是的话,这是否可行? 我不相信我能够观察所有灾后事件,因为它只是一个准确的对应点,而不是一个定期的表述。

@ Observer("org.jboss.seam.postCreate)

你们只能观察这些事件,而不能把这些事件列入关键人物的地图。

任何想法?

说 明

我愿获得一份所有组成部分的清单。

For each class declared as a component, Seam creates a component definition and stashes it away in the application scope. Its naming convention follows The pattern

  • <COMPONENT_NAME>.component

因此,你可以使用

/**
  * Metamodel class for component classes
  *
  * Similar to org.springframework.beans.factory.config.BeanDefinition used by Spring
  */ 
org.jboss.seam.Component

Context context = Contexts.getApplicationContext();
for (String name: context.getNames()) {
    Object object = context.get(name);
    if(object instanceof org.jboss.seam.Component) {
        Component component = (Component) object;

        System.out.println(component.getName());
        System.out.println(component.getType());
        System.out.println(component.getScope());
        System.out.println(component.getTimeout());
        System.out.println(component.isStartup());
        System.out.println(component.isSynchronize());
    }
}

如果你想要找到一个理想的构成部分,你可以使用

Object object = Component.getInstance(component.getName());
