*  确保jar包已经加载

本文使用maven方式加载相关jar包，pom.xml文件中配置项如下：

<dependency>
                <groupId>org.quartz-scheduler</groupId>
                <artifactId>quartz</artifactId>
                <version>2.2.2</version>
            </dependency>
    
            <dependency>

                    <exclusion>
                        <artifactId>commons-logging</artifactId>
                        <groupId>commons-logging</groupId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-tx</artifactId>

            </dependency>
            <dependency>

                <version>4.2.1</version>
            </dependency>

*  在web.xml文件中配置上下文

<context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-core.xml
            ,
            classpath:spring-hibernate.xml
            ,
            classpath:spring-quartz.xml 
            </param-value>
        </context-param>

*  在spring-quartz.xml文件中配置定时任务

                </list>
            </property>
        </bean>
    
    </beans>

*  在class类中，实现定时任务方法

package com.ytang.docinf.tool;
    
    /*执行定时任务 * kevin * 2017-04-18*/
    
    public class Task{  
    
        public void test(){  
            System.out.println("定时任务测试");  
    
        }  
    
    }
