quartz 的简单使用

0.依赖：

<!-- 引入quartz对应的依赖 -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.3</version>
        </dependency>

1.配置。

<!-- ******************定时任务quartz配置********************* -->
<!-- 注册自定义作业类 -->
    <bean id="myJob" class="com.shan.bos.service.jobs.MailJob">
        <property name="username" value="lsXXX"/>
        <property name="password" value="lXXX"/>
        <property name="smtpServer" value="XX.com"/>
    </bean>
    
    <!-- 配置JobDetail -->
    <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!-- 注入目标对象 即目标类 -->
        <property name="targetObject" ref="myJob"/>
        <!-- 注入目标方法 -->
        <property name="targetMethod" value="execute"/>
    </bean>
    
    <!-- 配置触发器 -->
    <bean id="myTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <!-- 注入任务详情对象 -->
        <property name="jobDetail" ref="jobDetail"/>
        <!-- 注入cron表达式，通过这个表达式指定触发的时间点 -->
        <property name="cronExpression">
            <value>0/10 * * * * ? 2019</value>
        </property>
    </bean>
    
    <!-- 配置调度工厂 -->
    <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <!-- 注入触发器 -->
        <property name="triggers">
            <list>
                <ref bean="myTrigger"/>
            </list>
        </property>
    </bean>
