Quartz使用

一、 quartz下载

官网：http://www.quartz-scheduler.org/

下载压缩包解压：

二、Quartz使用

1.创建maven工程，导入spring和quartz相关依赖

2.创建作业类

public class MailJob {
private String username;
private String password;
private String smtpServer;

public String getUsername() {
　　return username;
} 

public void setUsername(String username) {
　　this.username = username;
}

public String getPassword() {
　　return password;
}

public void setPassword(String password) {
　　this.password = password;
}
　　public void execute() {
　　　　//TODO 作业方法
　　}
　　public String getSmtpServer() {
　　　　return smtpServer;
}

public void setSmtpServer(String smtpServer) {
　　　　this.smtpServer = smtpServer;
　　}
}

3.在spring配置文件中配置作业类

<!-- 注册自定义作业类 -->
　　<bean id="myJob" class="com.itheima.jobs.MailJob">
　　<property name="username" value="20152543@163.com"/>
　　<property name="password" value="123456789"/>
　　<property name="smtpServer" value="smtp.163.com"/>
</bean>

4.在spring配置文件中配置JobDetail

<!-- quartz任务详情 -->
　　<bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
　　<!-- 注入目标对象 -->
　　<property name="targetObject" ref="myJob"/>
　　<!-- 注入目标方法 -->
　　<property name="targetMethod" value="execute"/>
</bean>

5.在spring配置文件中配置触发器

<!-- 配置触发器 -->
　　<bean id="myTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
　　<property name="jobDetail" ref="jobDetail"/>
　　<property name="cronExpression" value="0/5 * 12 * * ?"/>
</bean>

6.在spring配置文件中配置scheduler

<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
　　<property name="triggers">
　　　　<list>
　　　　　　<ref bean="myTrigger"/>
　　　　</list>
　　</property>
</bean>
