Question

我正在尝试使用Quartz 1.8.5（我也试过Quartz2.0 - 同样的问题）和Spring 3.0.0。但是，我不想在Quartz调度程序，触发器，作业中使用Spring的实用程序包装器...... 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 - 出于很多原因，但主要是因为我有需求动态触发器和JobDetails ......

所以，我在classpath上有我的quartz.properties，我定义了一个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，它使用来自同一示例的未修改的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，可以调用这个类：

@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");
    }

}

当我运行此单元测试时，我遇到以下错误 - 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 - 只是为了确保我能让它工作，但最终我想使用JobStoreCMT toplug进入Spring的事务管理。我找不到任何关于如何做到的好文档/示例，特别是如果我不想使用的话 Spring的调度程序包装和硬编码都是触发定义...

谢谢！

Answer 1

我最近也遇到过这个问题，（我在Mac OS X下使用Java7），以下内容对我有用：

首先，测试方法java.net.InetAddress.getLocalHost()是否有效，如果它抛出异常，如：

Caused by: java.net.UnknownHostException: leo-mbp: nodename nor servname provided, or not known
  at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
  at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:901)
  at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1293)
  at java.net.InetAddress.getLocalHost(InetAddress.java:1469)

运行以下内容以解决此问题：

scutil --set HostName "localhost"

希望它对你有所帮助。

Answer 2

@blob：你是正确的目标。花了好几个小时试图弄清楚为什么NotificationInitializer没有被初始化（正如建议的错误信息......）我终于试图从我的Spring配置中删除Quartz DB初始化脚本 - 而且一切都像魅力一样！

<jdbc:initialize-database data-source="dataSource"
    enabled="${database.initschema}">
    <jdbc:script location="${database.schemaLoc}" />
    <jdbc:script location="${database.seedLoc}" />
    <!-- <jdbc:script location="classpath:db/tables_mysql_innodb_1.8.5.sql" /> -->
</jdbc:initialize-database>

我只是希望Spring错误消息更具体......：）

现在，我仍然不明白为什么我不能以这种方式为Quartz创建数据库表 - 直接在数据库上运行时，相同的脚本工作得很好。也许在Spring中有一些奇怪的启动动作序列？

谢谢！

Answer 3

只是猜测：检查是否需要指定连接验证查询。就像是 validationQuery="select 1"

Answer 4

在quartz.properties文件中将“org.quartz.scheduler.instanceId”从AUTO更改为10对我有用。

无法在Spring中初始化Quartz Scheduler
