1 quartz介绍和下载
官网：http://www.quartz-scheduler.org/
Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目，它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个，百个，甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或 EJBs。Quartz的最新版本为Quartz 2.2.3

2 Quartz使用
第一步：创建maven工程，导入spring和quartz相关依赖
第二步：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;
}
}
第三步：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="[email protected]"/>
<property name="password" value="987654321wyx"/>
<property name="smtpServer" value="smtp.163.com"/>
</bean>
第四步：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>
第五步：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>
第六步：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>

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