1、加入依赖包：

<dependency>
       <groupId>org.quartz-scheduler</groupId>
       <artifactId>quartz</artifactId>
       <version>2.2.1</version>
    </dependency>
    <dependency>
       <groupId>org.quartz-scheduler</groupId>
       <artifactId>quartz-jobs</artifactId>
       <version>2.2.1</version>
    </dependency>

2、第一种方式：

写一个方法，并在其上方加入**@Scheduled**注释即可，如：

@Scheduled(cron = "0 0 0/2 * * ?")
    
     
      
      
       public void 
      
       test
      
       () { 
     
      // do something
       }

3、第二种方式：

3.1、写一个方法，如：

public class TestClass {
     /** * 定时器执行 */ public void execute() {
          //  do something ...
    }

3.2、编写**spring-quartz.xml**配置文件，如：

<?xml version="1.0" ecodn="TF-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-4.0.xsd
            ">
    
        
        <bean id="quartzTest" class="com.service.TestClass">
        </bean>
    
        <bean id="quartzJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
            <property name="targetObject" ref="quartzTest"></property>
            
            <property name="targetMethod" value="execute"></property>
            
            <property name="concurrent" value="false"></property>
        </bean>
    
        <bean id="testTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
            <property name="jobDetail" ref="quartzJob"/>
            <property name="cronExpression" value="0 0 12 * * ?"/>
        </bean>
    
        <bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    <ref bean="testTrigger"></ref>
                </list>
            </property>
        </bean>
    </beans>

最后将文件spring-quartz.xml加载到spring配置文件中即可！！！
