Java的几种定时任务
1、XML文件配置的job
web.xml<servlet><servlet-name>QuartzInitializer</servlet-name><servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class><init-param><param-name>shutdown-on-unload</param-name><param-value>true</param-value></init-param><init-param><param-name>config-file</param-name><param-value>quartz.properties</param-value></init-param><load-on-startup>2</load-on-startup></servlet>
quartz.properties
#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName = org.quartz.scheduler.instanceId = AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 3
org.quartz.threadPool.threadPriority = 5
#============================================================================
# Configure Plugins
#============================================================================
#org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingJobHistoryPlugin
#org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.class = com.coship.dhm.portalMS.common.util.DHMJobInitializer
#org.quartz.plugin.jobInitializer.fileName = quartz.xml
#\u5fc5\u987b\u6839\u636e\u5b9e\u9645\u60c5\u51b5\u914d\u7f6e\u6210quartz_nanjing-classify.xml\uff08\u5357\u4eac\u5206\u7ea7\uff09\u6216\u8005quartz_tianwei.xml \u6216 quartz_nanjing-no-classify.xml\uff08\u4e0d\u5206\u7ea7\uff09—>
org.quartz.plugin.jobInitializer.fileNames = quartz_tianwei.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = true
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 10
quartz_tianwei.xml
<?xml version=”1.0” encoding=”UTF-8”?>
2、spring框架
appContextServiceSynchronize.xml
<?xml version=”1.0” encoding=”UTF-8”?>
<!DOCTYPE beans PUBLIC “-//SPRING//DTD BEAN 2.0//EN” “http://www.springframework.org/dtd/spring-beans-2.0.dtd">
…….
appContextService.xml
<?xml version=”1.0” encoding=”UTF-8”?>
web.xml
<?xml version=”1.0” encoding=”UTF-8”?>

classpath:spring/applicationContext-operation.xml

3、Timer
public class SystemXmlFileTask extends TimerTask
public void run()
{
try\{init();\}catch (Exception e)\{logger.error("SystemXmlFileTask Exception" + e.getMessage());\}\}
//1.初始化系统配置文件刷新时间
int systemRefreshInterval = 60000;
try
{
systemRefreshInterval = Integer.parseInt(ctx.getInitParameter(SYSTEM_REFRESH_INTERVAL));
}
SystemXmlFileTask systemXmlFileTask = new SystemXmlFileTask(
configPath + FS + SYSTEMCONFIG_FILE_NAME);
systemXmlFileTask.init();
Timer timer = new Timer();
timer.schedule(systemXmlFileTask,
systemRefreshInterval,
systemRefreshInterval);
