shiro升级quartz到2.1.6版本

在做老司机的项目时，spring使用的是4.2.1版本，shiro用的是1.2.3，但是，spring扩展中 spring-context使用的quartz2的版本，
而shiro到现在还是使用的quartz1.6.1版本，所以，把spring降下来是不可能了，因为很多扩展都给予spring4，所以想把shiro升上去
是最好的解决方法，综合了网上升级spring的方法，使用以下方式升级shiro-quartz,实际上就是替换了shiro-quartz这个包，
实际上只用重写两个类就可以了，
具体实现类如下

package org.apache.shiro.session.mgt.quartz;

/**
 * Created by koko on 2016/7/20.
 */
import org.apache.shiro.session.mgt.ValidatingSessionManager;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * 基于Quartz 2.* 版本的实现
 *
 */
public class QuartzSessionValidationJob2 implements Job {

    /**
     * Key used to store the session manager in the job data map for this job.
     */
    public static final String SESSION_MANAGER_KEY = "sessionManager";

    /*--------------------------------------------
    |    I N S T A N C E   V A R I A B L E S    |
    ============================================*/
    private static final Logger log = LoggerFactory.getLogger(QuartzSessionValidationJob2.class);

    /*--------------------------------------------
    |         C O N S T R U C T O R S           |
    ============================================*/

    /*--------------------------------------------
    |  A C C E S S O R S / M O D I F I E R S    |
    ============================================*/

    /*--------------------------------------------
    |               M E T H O D S               |
    ============================================*/

    /**
     * Called when the job is executed by quartz. This method delegates to the <tt>validateSessions()</tt> method on the
     * associated session manager.
     *
     * @param context
     *            the Quartz job execution context for this execution.
     */
    public void execute(JobExecutionContext context) throws JobExecutionException {

        JobDataMap jobDataMap = context.getMergedJobDataMap();
        ValidatingSessionManager sessionManager = (ValidatingSessionManager) jobDataMap.get(SESSION_MANAGER_KEY);

        if (log.isDebugEnabled()) {
            log.debug("Executing session validation Quartz job...");
        }

        sessionManager.validateSessions();

        if (log.isDebugEnabled()) {
            log.debug("Session validation Quartz job complete.");
        }
    }

}

第二个类 spring注入的也是这个类

package org.apache.shiro.session.mgt.quartz;

/**
 * Created by koko on 2016/7/20.
 */
import org.apache.shiro.session.mgt.DefaultSessionManager;
import org.apache.shiro.session.mgt.SessionValidationScheduler;
import org.apache.shiro.session.mgt.ValidatingSessionManager;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.SimpleTrigger;
import org.quartz.TriggerBuilder;
import org.quartz.TriggerKey;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * 基于Quartz 2.* 版本的实现
 */
public class QuartzSessionValidationScheduler2 implements SessionValidationScheduler {

    public static final long DEFAULT_SESSION_VALIDATION_INTERVAL = DefaultSessionManager.DEFAULT_SESSION_VALIDATION_INTERVAL;
    private static final String JOB_NAME = "SessionValidationJob";
    private static final Logger log = LoggerFactory.getLogger(QuartzSessionValidationScheduler2.class);
    private static final String SESSION_MANAGER_KEY = QuartzSessionValidationJob2.SESSION_MANAGER_KEY;
    private Scheduler scheduler;
    private boolean schedulerImplicitlyCreated = false;

    private boolean enabled = false;
    private ValidatingSessionManager sessionManager;
    private long sessionValidationInterval = DEFAULT_SESSION_VALIDATION_INTERVAL;

    public QuartzSessionValidationScheduler2() {
    }

    public QuartzSessionValidationScheduler2(ValidatingSessionManager sessionManager) {
        this.sessionManager = sessionManager;
    }

    protected Scheduler getScheduler() throws SchedulerException {
        if (this.scheduler == null) {
            this.scheduler = StdSchedulerFactory.getDefaultScheduler();
            this.schedulerImplicitlyCreated = true;
        }
        return this.scheduler;
    }

    public void setScheduler(Scheduler scheduler) {
        this.scheduler = scheduler;
    }

    public void setSessionManager(ValidatingSessionManager sessionManager) {
        this.sessionManager = sessionManager;
    }

    public boolean isEnabled() {
        return this.enabled;
    }

    public void setSessionValidationInterval(long sessionValidationInterval) {
        this.sessionValidationInterval = sessionValidationInterval;
    }

    public void enableSessionValidation() {
        if (log.isDebugEnabled()) {
            log.debug("Scheduling session validation job using Quartz with session validation interval of ["
                    + this.sessionValidationInterval + "]ms...");
        }

        try {
            SimpleTrigger trigger = TriggerBuilder.newTrigger().startNow().withIdentity(JOB_NAME, Scheduler.DEFAULT_GROUP)
                    .withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInMilliseconds(sessionValidationInterval))
                    .build();//<span style="color:#ff0000;">Quartz 2中的实现</span>

            JobDetail detail = JobBuilder.newJob(QuartzSessionValidationJob2.class)
                    .withIdentity(JOB_NAME, Scheduler.DEFAULT_GROUP).build();
            detail.getJobDataMap().put(SESSION_MANAGER_KEY, this.sessionManager);
            Scheduler scheduler = getScheduler();

            scheduler.scheduleJob(detail, trigger);
            if (this.schedulerImplicitlyCreated) {
                scheduler.start();
                if (log.isDebugEnabled()) {
                    log.debug("Successfully started implicitly created Quartz Scheduler instance.");
                }
            }
            this.enabled = true;

            if (log.isDebugEnabled())
                log.debug("Session validation job successfully scheduled with Quartz.");
        } catch (SchedulerException e) {
            if (log.isErrorEnabled())
                log.error("Error starting the Quartz session validation job.  Session validation may not occur.", e);
        }
    }

    public void disableSessionValidation() {
        if (log.isDebugEnabled()) {
            log.debug("Stopping Quartz session validation job...");
        }
        Scheduler scheduler;
        try {
            scheduler = getScheduler();
            if (scheduler == null) {
                if (log.isWarnEnabled()) {
                    log.warn("getScheduler() method returned a null Quartz scheduler, which is unexpected.  Please check your configuration and/or implementation.  Returning quietly since there is no validation job to remove (scheduler does not exist).");
                }

                return;
            }
        } catch (SchedulerException e) {
            if (log.isWarnEnabled()) {
                log.warn("Unable to acquire Quartz Scheduler.  Ignoring and returning (already stopped?)", e);
            }
            return;
        }
        try {
            scheduler.unscheduleJob(new TriggerKey("SessionValidationJob", "DEFAULT"));
            if (log.isDebugEnabled())
                log.debug("Quartz session validation job stopped successfully.");
        } catch (SchedulerException e) {
            if (log.isDebugEnabled()) {
                log.debug("Could not cleanly remove SessionValidationJob from Quartz scheduler.  Ignoring and stopping.", e);
            }

        }

        this.enabled = false;

        if (this.schedulerImplicitlyCreated)
            try {
                scheduler.shutdown();
            } catch (SchedulerException e) {
                if (log.isWarnEnabled())
                    log.warn("Unable to cleanly shutdown implicitly created Quartz Scheduler instance.", e);
            } finally {
                setScheduler(null);
                this.schedulerImplicitlyCreated = false;
            }
    }

}

最后在spring的配置文件中配置shiro的quartz配置

<bean id="sessionValidationScheduler"
		  class="org.apache.shiro.session.mgt.quartz.QuartzSessionValidationScheduler2">
		<property name="sessionValidationInterval" value="1800000"/>
		<property name="sessionManager" ref="sessionManager"/>
	</bean>

大功告成，oh yeah
