The null pointer problem occurs when the bean is not injected with the quartz development schedule

When you develop a job class, @Autowired annotations do not work and a null pointer exception occurs:

Reason: Because @autowired is injecting attributes into the job class instance of spring injection. In our job class, when the method executes, quartz instantiates a jobclass, which is different from the instance of spring injection, so there is no attribute and the property is empty.

On the internet to find a lot of methods are said to Springbeanjobfactory, I tried, no use.

There is a way to use it, rewrite applicationcontextaware, and get the bean in the job's execute (), which is implemented as follows:

Package Com.operation.quartzManger;

Import Java.util.Locale;

Import Com.operation.mapper.SystemView;
Import org.springframework.beans.BeansException;
Import Org.springframework.context.ApplicationContext;
Import Org.springframework.context.ApplicationContextAware;

/**
 * System Bean help class */public
class Springcontextutil 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 ());
	}

To inject a help class into spring

<ID= "springcontextutilclass=" Com.operation.quartzManger.SpringContextUtil "></Bean>

The execution method in the job class is called:

SystemView systemview= (SystemView) Springcontextutil.getbean ("SystemView");

Systemview.updatesysstatusbyid (Sysuuid,"1","System normal");

The test system is normal.
