在服务器开端期间,我如何启动特定天线
原标题:How to I initiate specific spring bean during server start up

我在申请中使用一些支持数据,我想在服务器开始时装上这一数据。 I m使用春季环境。 如果在服务器启用时我能够装上应用环境,这个问题将得到解决。

问题回答

http://docs.oracle.com/javaee/6/apix/faces/bean/ApplicationScoped.html

@ManagedBean(eager=true)
@ApplicationScoped
public class Data {

    // ...

}

这将在网络启动上使管理过的灯塔自动化。

Register a ServletContextListener and fetch the bean in contextInitialized() (see Servlet Life-Cycle Events).

这有两个好处:

  1. You can fetch several beans in a predefined order (this should never be necessary but, well, reality always wins)
  2. It won t interfere with your tests
