Java用qq邮箱定时发送邮件

一、QQ邮箱-->设置-->账户-->开启POP3/SMTP服务-->短信验证-->获取授权码

 

 

 

 

 二、SSM项目代码（Spring、SpringMVC、Mybatis）

1.pom.xml

    <!-- mail begin -->
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>activation</artifactId>
        <version>1.0.2</version>
    </dependency>
    
    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4.7</version>
    </dependency>
    <!-- mail end -->
          
      <!-- 定时任务begin -->
      <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.3.0</version>
    </dependency>
    <!-- 定时任务end -->

2.springmvc-context.xml

    <!--  定时器begin -->
    <!--  调度业务对象 即自己的定时任务类-->
    <bean id = "spiderJob" class="com.dahata.controller.JobController"/>
    <!--  调度业务 -->
    <bean id = "jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name= "targetObject" ref="spiderJob"/>
        <property name ="targetMethod" value="startWork"/>
    </bean>
    <!--  调度器触发器 每天早上08:00执行一次 -->
    <bean id="taskTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="jobtask"/>
        <property name="cronExpression" value="0 00 08 * * ? *"/>
    </bean>
    <!--  设置调度  list里面可以添加多个调度触发器  -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
              <list>
                   <ref bean="taskTrigger" />
              </list>
         </property>
    </bean>
    <!-- 定时器end -->
