1、要实现
org.quartz.Job 接口中的以下方法
void execute(JobExecutionContext var1) throws JobExecutionException;
2、在 org.quartz.Job接口中的 execute方法中 使用 testService 会出现 testService==null的情况,所以要在
QuartzManager.java 类中的
addJob方法里面添加
sched.setJobFactory(myJobFactory); (很重要)
@Autowired
private TestService testService;
3、java 代码实现
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class QuartzJobTest implements Job {
private static final Logger logger= LoggerFactory.getLogger(QuartzJobTest.class);
@Autowired
private TestService testService;
/**
* 执行 job
* @param jobExecutionContext
* @throws JobExecutionException
*/
@Override
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
try{
JobDataMap map = jobExecutionContext.getJobDetail().getJobDataMap();
String payCompanyCode= (String) map.get("payCompanyCode");
PayCompany payCompany=testService.getCompanyByCode(payCompanyCode);
}catch (Exception e){
logger.error("QuartzJob execute error",e);
}
}
}
