JobDataMap传递参数

JobDataMap传递参数_02

JobDataMap属于JobDetail的一部分
可以在构建JobDataMap时传递参数

取出参数2种形式：
第1种：可以从execute方法的上下文中取出参数
第2种：在Job类中，定义参数名称，完成getset方法

推荐使用第2种+lombok

添加参数

        //创建JobDetailJobDetail jobDetail = JobBuilder.newJob(MyJob.class)//唯一标识.withIdentity("jobDetail1", "group1")//添加参数通过usingJobData方法，传递给job.usingJobData("name","yx").build();

第1种：可以从execute方法的上下文中取出参数

package com.gblfy.job;import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;import java.time.LocalTime;public class MyJob implements Job {@Overridepublic void execute(JobExecutionContext context) throws JobExecutionException {LocalTime localTime = LocalTime.now();/*1.从上下文中先获取getJobDetail2.再从getJobDetail中获取JobDataMap3.最后，从JobDataMap中，根据key获取对应属性的值*/JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();String name = jobDataMap.getString("name");System.out.println("hello " + name + "我正在执行" + localTime);}
}

第2种：在Job类中，定义参数名称，完成getset方法

package com.gblfy.job;import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;import java.time.LocalTime;public class MyJob implements Job {private String name;public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic void execute(JobExecutionContext context) throws JobExecutionException {LocalTime localTime = LocalTime.now();System.out.println("hello " + name + "我正在执行" + localTime);}
}

为了减少代码，建议引入lombok

 </dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.12</version></dependency>

刚才的代码，简化为

package com.gblfy.job;import lombok.Getter;
import lombok.Setter;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.time.LocalTime;public class MyJob implements Job {@Getter@Setterprivate String name;@Overridepublic void execute(JobExecutionContext context) throws JobExecutionException {LocalTime localTime = LocalTime.now();System.out.println("hello " + name + "我正在执行" + localTime);}
}
