工具類中使用service

（1）工具類 SpringUtil.java

package com.googosoft.until;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class SpringUtil implements ApplicationContextAware {
    private static ApplicationContext appCtx;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        appCtx = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return appCtx;
    }

    public static Object getBean(String beanName) {
        return appCtx.getBean(beanName);
    }
}

注：類上要加@Component注解，否則會報空指針

 

（2）使用

package com.googosoft.job;

import javax.annotation.Resource;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import com.googosoft.service.QualityEvaluationService;
import com.googosoft.until.SpringUtil;
import com.googosoft.util.PageData;

/**
 * @author songyan
 * @date 2020年3月31日 下午1:51:33
 * @desc 作業
 */
public class EvaluationPlanJob implements Job {
    
    @Resource
    private QualityEvaluationService service = (QualityEvaluationService) SpringUtil.getBean("qualityEvaluationService");

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
       JobDataMap data = context.getJobDetail().getJobDataMap();
        PageData pd = new PageData();
        pd.put("GID", data.get("GID"));
        pd.put("DBMETAGID", data.get("DBMETAGID"));
        service.runEvaluationPlanList(pd);
    }

}

 

（3）關鍵代碼：

1）使用Resource注解

2）beanName：service類名首字母小寫
