【问题描述】:
我正在尝试在 Spring 3.0.0 中使用 Quartz 1.8.5(我也尝试过 Quartz2.0 - 同样的问题)。 但是,我不想将 Spring 的实用程序包装器用于 Quartz 调度程序、触发器、作业...... 我想从我的应用程序中以编程方式创建所有这些对象,就像在 没有容器的独立 Java 应用程序 - 有很多原因,但主要是因为我有以下要求 动态触发器和 JobDetails...
所以,我在类路径中有我的 quartz.properties,我在其中定义了一个 JobStoreTX:
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 Initializer 类,几乎与 Quartz 发行版的 example1 一样, 它使用了同一示例中未修改的 HelloJob:
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) {
.....
}
}
}
我还有一个简单的单元测试调用这个类:
@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时,我遇到了以下错误 - 请参阅下面的完整堆栈跟踪:
引起:org.springframework.beans.factory.BeanCreationException: 创建名为 'org.springframework.jdbc.datasource.init.DataSour ceInitializer#0' 的 bean 时出错: 调用 init 方法失败;嵌套异常是 com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 查询为空
知道出了什么问题吗?
另外,我现在正在设置 JobStoreTX - 只是为了确保我可以让它工作, 但最终我想使用 JobStoreCMT 来插入 Spring 的事务管理。 我找不到任何关于如何做到这一点的好的文档/示例,特别是如果我不想使用 Spring 的调度程序包装器和硬编码所有触发器定义...
谢谢!

-
你能发布你的spring bean配置吗?您是否在 spring 应用程序上下文加载时使用脚本初始化石英的数据库?
-
是的,就是这个原因!在下面查看我更详细的答案...谢谢!
