下面是我在初始化的时候处理的quartz的corn

public class MainSetup implements Setup {

    private static final Logger log = Logger.getLogger(MainSetup.class);

    @Override
    public void destroy(NutConfig conf) {
        ThreadPoolManager.getInstance().destroy();
    }

    @Override
    public void init(NutConfig conf) {
        log.info("MainSetup init ----------------------");
        Ioc ioc = conf.getIoc();
        Dao backendDao = ioc.get(Dao.class, "backendDao");//后台数据库连接

        log.info("后台数据库连接 配置读取 backendDao:" + backendDao);

        Dao publicServerDao = ioc.get(Dao.class, "daoPublic");//公共数据库
        ioc.get(NutQuartzCronJobFactory.class);

        Daos.createTablesInPackage(backendDao, "com.backend", false);

这个在入口方法处理的quartzloader

@SetupBy(MainSetup.class)
@Modules(scanPackage=true)
@IocBy(type=ComboIocProvider.class, args={
    "*js", "ioc/",
    "*anno", "com.backend",
    "*tx",
    "*org.nutz.integration.quartz.QuartzIocLoader"})
@Fail("jsp:jsp.500")
@Localization(value="language/", defaultLocalizationKey="zh_CN")
@Filters(@By(type = CheckSession.class,args={"USER","/user/tologin"}))
public class MainModule {}

有没有自行添加quartz.js?

下面是自己填的quartz.js

var ioc = {
   "scheduler" :{
      "type" :"org.quartz.Scheduler",
      "factory" :"org.quartz.impl.StdSchedulerFactory#getDefaultScheduler",
      "events" :{
         "create" :"start",
         "depose" :"shutdown"
      },
      "fields" :{
         "jobFactory" :{
            "refer" :"jobFactory"
         }
      }
   },
   "jobFactory" :{
      "type" :"org.nutz.integration.quartz.NutQuartzJobFactory",
      "args" :[{
         "refer" :"$ioc"
      }]
   },
   "nutQuartzCronJobFactory" :{
      "type" :"org.nutz.integration.quartz.NutQuartzCronJobFactory",
      "events" :{
         "create" :"init"
      },
      "fields" :{
         "scheduler" :{
            "refer" :"scheduler"
         },
         "conf" :{
            "refer" :"conf"
         }
      }
   } 
};

一般来说不需要自行添加

不过里面已经有 "depose" :"shutdown", 理应关闭quartz了

 org.nutz.dao.impl.NutDao.<init>(NutDao.java:104)
 com.backend.utils.DbConfigUtil.getNutDao(DbConfigUtil.java:61)
 com.backend.timer.OnlinePlayerJob.execute(OnlinePlayerJob.java:56)
 org.quartz.core.JobRunShell.run(JobRunShell.java:202)
 org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:573)

你这个JobRunShell是一直阻塞的?

我的理解应该没有阻塞吧？由于quartz并没有因为Tomcat关闭而关闭，到时任务触发的时候再次启动，然后数据库又在Tomcat关闭的时候关闭了，而无法正常再次链接，所以报了这个异常，不知道这个理解是不是对的。

已经调用过shutdown的

还可以在depose的时候

conf.getIoc().get(Scheduler.class).shutdown(true);

但看这日志,像是卡在JobRunShell里面

好的，我试试，谢谢老师
