设置的是30分钟，启动项目后并不立即执行非要等一次30分钟后才执行
没改之前是正常的啊！
代码如下：
QuartzConfiguration：

package com.apa7.weather_data.config.quartz;

import com.apa7.weather_data.job.WeatherDataSyncJob;
import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class QuartzConfiguration {

    private static final int TIME = 1800; // 更新频率

    // JobDetail
    @Bean
    public JobDetail weatherDataSyncJobDetail() {
        return JobBuilder.newJob(WeatherDataSyncJob.class).withIdentity("weatherDataSyncJob")
                .storeDurably().build();
    }

    // Trigger
    @Bean
    public Trigger weatherDataSyncTrigger() {

        SimpleScheduleBuilder schedBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(TIME).repeatForever();

        return TriggerBuilder.newTrigger().forJob(weatherDataSyncJobDetail())
                .withIdentity("weatherDataSyncTrigger").withSchedule(schedBuilder).build();
    }

}

WeatherDataSyncJob:

package com.apa7.weather_data.job;


import com.apa7.weather_data.service.DataService;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
* 定时获取天气数据
* */
public class WeatherDataSyncJob extends QuartzJobBean {

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("spring定时任务方法");
    }
}
