Solve the problem that Spring+quartz cannot inject beans

Task class
Import Org.springframework.scheduling.quartz.QuartzJobBean;
public class Ordersquartz extends quartzjobbean{
@Resource
Private OrderService OrderService;
@Override
protected void Executeinternal (Jobexecutioncontext arg0) throws Jobexecutionexception {
Task content
Orderservice.saveorders (orders);
}
}

Problem
Nullpointexception
OrderService is null. The method is not called.
Solve:
1. Add a System helper class
Package Com.ak.orders.quartz;

Import Java.util.Locale;
Import org.springframework.beans.BeansException;
Import Org.springframework.context.ApplicationContext;
Import Org.springframework.context.ApplicationContextAware;
/**
* System Bean Helper 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 ());
}
}
2. Add a bean to the spring configuration file
<bean id= "Springcontextutil" class= "Com.ak.orders.quartz.SpringContextUtil" ></bean>
3. Program Get Bean Code
Private OrderService OrderService = (orderservice) springcontextutil.getbean ("parms");
