Get spring's webapplicationcontext or ServletContext in Quartz's job

Sometimes we need to get spring's IOC container in the Timer class in the Web project, Webapplicationcontext, to get all the beans that implement an interface, because @autowired seems to inject only a single bean.

At first I was writing a servletcontextlistener, when starting the server to construct the timer and start, the Webapplicationcontext to the timer job, In Servletcontextlistener this gets webapplicationcontext:

1. Webapplicationcontextutils.getrequiredwebapplicationcontext (ServletContext);

Then call Webapplicationcontext.getbeansoftype (Infoservice.class) in the job to get all the beans that implement the interface.

In fact, can be simpler, less nonsense, this is a Pojo job:

[Java]View PlainCopy

2. Package com.gxjy.job;
6. Import Java.util.Map;
10. Import org.springframework.beans.factory.annotation.Autowired;
12. Import Org.springframework.web.context.ContextLoader;
14. Import Org.springframework.web.context.WebApplicationContext;
18. Import Com.gxjy.dao.InfoDao;
20. Import Com.gxjy.service.InfoService;
22. Import Com.gxjy.service.runnable.DudeRunner;
26. Public class scrawlerjob{
30. @Autowired
32. private Infodao Infodao;
36. public Void execute () {
38. Webapplicationcontext WAC = Contextloader.getcurrentwebapplicationcontext ();
40. map<string, infoservice> map = Wac.getbeansoftype (infoservice.   Class);
42. For (Infoservice infoService:map.values ()) {
44. System.out.println ("Start:" +infoservice.getclass (). GetName ());
46. New Thread (new Duderunner (Infoservice, Infodao)). Start ();
48. }
50. }
54. }

Focus on

[Java]View PlainCopy

1. Contextloader.getcurrentwebapplicationcontext ();

This can be directly obtained webapplicationcontext, of course, you can further call Getservletcontext () to get to ServletContext.

This is the configuration for quartz in spring:

MAVEN relies on additional spring-context-support dependencies (including support for quartz) in addition to the basic spring and quartz:
