我试图使用Quartz 1.8.5初始化Quartz调度（我也试过Quartz2.0 - 同样的问题）使用Spring 3.0.0。 不过，我不想使用Spring的工具包装的石英调度，触发器，工作... 我想从我的应用程序编程创建所有这些对象，就像在一个没有容器 独立的Java应用程序 - 许多的原因，但主要是因为我有 动态触发器和JobDetails要求...不能在春
所以，我在类路径中，在那里我定义了一个JobStoreTX我quartz.properties：
org.quartz.scheduler.instanceName: NotificationsScheduler
org.quartz.scheduler.instanceId: AUTO
org.quartz.scheduler.skipUpdateCheck: true
org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 3
org.quartz.threadPool.threadPriority: 5
org.quartz.jobStore.misfireThreshold: 60000
org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties: false
org.quartz.jobStore.dataSource: qzDS
org.quartz.jobStore.tablePrefix: QRTZ_
org.quartz.jobStore.isClustered: false
org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/myschema
org.quartz.dataSource.qzDS.user: myuser
org.quartz.dataSource.qzDS.password: mypwd
org.quartz.dataSource.qzDS.maxConnections: 5
然后，我有一个简单的初始化类，几乎和Quartz发行版的example1一样， 其使用的未改性HelloJob来自相同例如：
public class NotificationInitializer {
public void init(){
try {
SchedulerFactory schdFact = new StdSchedulerFactory("quartz.properties");
Scheduler schd = schdFact.getScheduler();
schd.start();
JobDetail jd = new JobDetail("hellojob", Scheduler.DEFAULT_GROUP, HelloJob.class);
Trigger t = TriggerUtils.makeImmediateTrigger(2, 1000);
t.setStartTime(new Date());
schd.scheduleJob(jd, t);
// wait long enough so that the scheduler as an opportunity to run
..........
schd.shutdown(true);
} catch (SchedulerException e) {
.....
}
}
}
我也有一个简单的单元测试调用此类：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext.xml")
public class NotificationInitializerTest {
private final static Logger logger = LoggerFactory
.getLogger(NotificationInitializerTest.class);
@BeforeClass
public static void setupClass() {
PropertyConfigurator.configure(Loader
.getResource("spring/log4j.properties"));
PropertyConfigurator.configure(Loader
.getResource("spring/quartz.properties"));
}
@Test
public void testInit() {
NotificationInitializer ni = new NotificationInitializer();
ni.init();
logger.info("NotificationInitializer.init() finished OK");
}
}
当我运行这个单元测试我收到以下错误 - 请参见下面的完整的堆栈跟踪：org.springframework.beans.factory.BeanCreationException：
所致 错误创建名称为豆“org.springframework.jdbc.datasource.init.DataSour ceInitializer＃ 0'： 调用init方法失败;嵌套的异常是com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException： 查询是空的
任何想法出了什么问题？
此外，我现在设置JobStoreTX - 只是为了确保我可以得到它， 但最终我想使用JobStoreCMT toplug intoSpring的事务管理。 我找不到任何好的文档/示例如何做到这一点，特别是如果我不想使用 Spring的包装调度程序和硬编码所有触发器定义...
谢谢！ Marina

你可以发布你的spring bean配置吗？在spring应用程序上下文加载时，是否使用脚本初始化quartz的DB？ – blob
是的，那是原因！看到我下面更详细的答案...谢谢！ – Marina
