在基于struts+spring+hibernate的开发框架下，一般service都是直接通过在Struts的action中getBean("yourServiceName")来获取，那么如果在serviceA中想调用serviceB中的方法该如何呢？

    直接new 一个serviceB是不行的，因为里面可能还有依赖注入的dao等其他本来需要容器管理的资源，可以象在action中一样getBean()么？

    获得applicationContext就可以了：

AppContext ：

public class AppContext ...{
    private static ApplicationContext applicationContext;

    public static ApplicationContext getApplicationContext() ...{
        return applicationContext;
    }
    public static void setApplicationContext(
            ApplicationContext applicationContext) ...{
        AppContext.applicationContext = applicationContext;
    }
}

SpringService：

public class SpringBeanService ...{
    private static SpringBeanService instance;

    private ApplicationContext applicationContext;

    public static synchronized SpringBeanService getInstance() ...{
        if (instance == null) ...{
            instance = new SpringBeanService();
        }
        return instance;
    }

    public ApplicationContext getApplicationContext() ...{
        return this.applicationContext;
    }

    public void setApplicationContext(ApplicationContext applicationContext) ...{
        this.applicationContext = applicationContext;
    }

    public UserService getUserService()...{
        return (UserService)AppContext.getApplicationContext().getBean("userService");
    }

    }

ApplicationContext的初始化：

public class ConfigLoadListener implements ServletContextListener ...{

    public void contextInitialized(ServletContextEvent contextEvent) ...{
        try ...{
            WebApplicationContext context =WebApplicationContextUtils.getRequiredWebApplicationContext
(contextEvent.getServletContext());
            AppContext.setApplicationContext(context);

            //读配置
            try ...{
                ServletContext context2=contextEvent.getServletContext();
                String path=context2.getInitParameter("setting.properties");
                InputStream in =context2.getResourceAsStream(path);
                Properties properties = new Properties();
                properties.load(in);
                GlobalConstant.setCmdbProperties(properties);
                in.close();
            } catch (IOException e) ...{
                e.printStackTrace();
            }
        } catch (HibernateException e) ...{
            System.out.println("系统无法初始化,异常退出");
            System.out.println(e);
        }
    }

    public void contextDestroyed(ServletContextEvent contextEvent) ...{
    }
}

 感觉有点麻烦，有更简便的办法了么？
