spring-boot启动项目时候，出现错误 Field scheduler in com.jeesite.modules.quartz.service.QuartzJobService

今天整合jeesite4项目时，将jeecg里面的定时器功能拿出来集成到jeesite4中，启用服务器的时候出现了如下错误：

Description:

Field scheduler in com.jeesite.modules.quartz.service.QuartzJobService required a bean of type 'org.quartz.Scheduler' that could not be found.


Action:

Consider defining a bean of type 'org.quartz.Scheduler' in your configuration.

========= Enabled refresh mybatis mapper =========

字面上就是service里面无法找到Scheduler,这个应该是在启动的时候未注入到容器中，
后来谷歌搜了一个方法，将获取Scheduler用方法注入进去，这样就解决问题啦，记录下问题。花了有点长的时间。

 
package com.jeesite.modules.quartz.service;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SampleSchedulerConfiguration {
    @Bean
    public Scheduler getScheduler() throws SchedulerException       
	 return StdSchedulerFactory.getDefaultScheduler();
  }

}

@Component 是类级别的注解 @Bean方法级别的注解 用他的方法名作为名字注入到容器中，以供其他service调用。写好后就可以正常启动了
