详细的错误信息如下：

说说我的解决过程：

一、原因很明显：调用了null对象。

但是这是因为我调用了service的方法

 我用的方法

静态工具类

创建工具类SpringContextJobUtil，实现ApplicationContextAware接口,此工具类会在spring容器启动后，自动加载，使用其提供的getBean方法获取想要的bean即可

@Component
public class SpringContextJobUtil implements ApplicationContextAware  {

    private static ApplicationContext context;

    @Override
    @SuppressWarnings("static-access" )
    public void setApplicationContext(ApplicationContext contex)
            throws BeansException {
        // TODO Auto-generated method stub
        this.context = contex;
    }
    public static Object getBean(String beanName){
        return context.getBean(beanName);
    }

    public static String getMessage(String key){
        return context.getMessage(key, null, Locale.getDefault());
    }
}

在job内直接调用静态方法

testSuitService = (TestSuitService) SpringContextJobUtil.getBean("testSuitService");
