项目中需要有一个定时任务，在每年一月一日查询人员表中的信息，根据身份证号码，修改用户年龄。项目使用架构为Spring，Spring MVC，Mybaits。所以引入了Quartz做定时任务。  
**1.引入相关jar**

<dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context-support</artifactId>
                <version>${spring.version}</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz</artifactId>
                <version>2.2.2</version>
            </dependency>
            <dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz-jobs</artifactId>
                <version>2.2.2</version>
            </dependency>

2.新建spring-quartz.xml文件并配置：

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    
        
        <bean id="userBirthdayJob" class="com.acat.quartz.UserBirthdayJob">
        </bean>
    
        
        <bean id="testJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
            
            <property name="targetObject" ref="userBirthdayJob"></property>
            
            <property name="targetMethod" value="updateUserAge"></property>
            
            <property name="concurrent" value="false"></property>
        </bean>
    
        
        
        <bean id="everyYearTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
            
            <property name="jobDetail">
                <ref bean="testJob" />
            </property>
            
            <property name="cronExpression">
                <value>0 0 1 1 1 ? *</value>
            </property>
        </bean>
    
        
        
         <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    
                    <ref bean="everyYearTrigger"></ref>
                </list>
            </property>
        </bean>
    </beans>

**3.定时任务执行类**

package com.acat.quartz;
    
    /**
     * @Description：每年定时修改用户年龄的定时任务
     * @Author:
     * @Date: Created in 10:57 2019-03-30
     * @Modified By:
     */
    public class UserBirthdayJob{
    
        /**
         * 修改用户年龄的定时任务
         */
        public void updateUserAge() {
            //TODO 查询出所有人员信息，并修改年龄
        }
    }
