spring cron expression must consist of 6 fields 已解决，亲测有效

使用spring3.1 以注解的形式配置定时任务

当我想把定时任务的时间放入配置文件里去，然后动态获取的时候，总是报
cron expression must consist of 6 fields (found 1 in ${job.schedule})

百思不得其解

我的定时任务类：

/*** */
package com.dounion.bas.util;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;import com.dounion.bas.business.BasSyndataBusiness;/*** @author Administrator**/
@Configuration //1.主要用于标记配置类，兼备Component的效果。
@EnableScheduling // 2.开启定时任务
@PropertySource("classpath:/bas.properties")
public class TimerTask_bas{/** 注入行动Dao类 **/@Autowiredprivate BasSyndataBusiness basSyndataBusiness;@Beanpublic static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {return new PropertySourcesPlaceholderConfigurer();}/*** * author: kangyu* 2018-11-26 下午5:32:29* @Description: // 查询同步日志表发送给库点(每隔1分钟触发一次)*/@Scheduled(cron = "${job.schedule}")public void sendDataToLibraryPoint() {basSyndataBusiness.sendDataToLibraryPoint();}@Scheduled(cron = "${job.schedule}")public void dealDataInRedis() {basSyndataBusiness.dealDataInRedis();}}

TimerTask_bas类主要加了以下几行才解决如上bug

	@Beanpublic static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {return new PropertySourcesPlaceholderConfigurer();}

配置文件bas.properties是这么写的job.schedule = 0 */1 * * * ?。
application.xml主要代码：

	<context:annotation-config /><context:component-scan base-package="com.dounion" /><aop:aspectj-autoproxy proxy-target-class="true" />
