錯誤描述：
在介面Service中宣告CmdbInfoWebServiceFunction時初始化失敗，

    private CmdbInfoWebServiceFunction synchronizationDataWebServiceFunction = (CmdbInfoWebServiceFunction) SpringApplicationContextHelper.getContext().getBean("SynchronizationDataWebServiceFunction");

除錯時發現SpringApplicationContextHelper.getContext()的值為空；
SpringApplicationContextHelper類如下：

package com.eshore.cmdb.common.base.util;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringApplicationContextHelper
{
    static{
        SpringApplicationContextHelper.context = new ClassPathXmlApplicationContext("spring.xml"
 
);
    }

    private static ApplicationContext context;

    /**
     * @return  context
     */
    public static ApplicationContext getContext()
    {
        return context;
    }

    /**
     * @param context: 你要設定的context 
     */
    public static void setContext(ApplicationContext context)
    {
        SpringApplicationContextHelper.context = context;

    }

    public
 
 static Object getBean(String beanStr)
    {
        return context.getBean(beanStr);
    } 

}

在該類中設定context為靜態變數後錯誤消失

    static{
        SpringApplicationContextHelper.context = new ClassPathXmlApplicationContext("spring.xml");
    }
