異步方法調用

我有兩個類在java ee中調用asynchronus方法調用。我正在關注鏈接http://satishgopal.wordpress.com/2011/04/24/ejb-3-1-asynchronous-methods以瞭解如何操作。當我調用異步方法時，我有以下結果。異步方法調用

結果：

INFO: caller method running in thread http-thread-pool-8083(5) date:1373866669346 
INFO: start running asyncMethod in thread http-thread-pool-8083(5) 

INFO: finished running asyncMethod in thread http-thread-pool-8083(5) 
INFO: caller method running in thread http-thread-pool-8083(5) date:1373866672348

我所期待的不是等待然而asyncMethod（）方法invcation完成，你可以從結果asyncMethod（）方法invcation沒有被另一個線程處理看到的。使用Glassfish 3.1.1作爲應用程序容器。

BusinessBean類

@ManagedBean 
@Stateless 
public class BusinessBean { 

@Asynchronous 
public void asyncMethod() { 
    System.out.println("start running asyncMethod in thread "+ Thread.currentThread().getName()); 

    try { 
     Thread.sleep(3000); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 

    System.out.println("finished running asyncMethod in thread "+ Thread.currentThread().getName()); 
} 

}

LoginBean類

@ManagedBean 
@RequestScoped 
public class LoginBean implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @ManagedProperty(value="#{businessBean}") 
    BusinessBean businessBean; 


    private String name; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 


    public void login(){   
     System.out.println("caller method running in thread "+Thread.currentThread().getName()+" date:"+System.currentTimeMillis()); 
     businessBean.asyncMethod(); 
     System.out.println("caller method running in thread "+Thread.currentThread().getName()+" date:"+System.currentTimeMillis()); 
    } 

    public BusinessBean getBusinessBean() { 
     return businessBean; 
    } 

    public void setBusinessBean(BusinessBean businessBean) { 
     this.businessBean = businessBean; 
    } 


}

嘗試使用@EJB註釋注入'BusinessBean'。 –

擺脫ManagedBean標註爲BusinessBean的：它應該是一個企業的Java Bean，它是多虧了@Stateless註解。

通過@EJB裝置還注入它：

@EJB 
private BusinessBean businessBean;

用於進一步參考見this link。
