Java SimpleThreadPool的Quartz ClassNotFoundException

我正在尝试配置仅在一个节点（）上运行的quartz调度程序。每当我设置quartz线程池时，它都会告诉我无法找到

SimpleThreadPool

，即使它是通过

spinscale/dropwizard作业加载到我的项目中的。加载的版本为
quartz-2.2.3

我正在使用将quartz集成到dropwizard项目中。我正在使用dropwizard 1.0.5、dropwizard guicey 4.0.1（）、spinscale quartz实现3.0.0

我通过以下示例连接了依赖项注入：

我已经将以下文件添加到我的项目中
quartz.properties

org.quartz.scheduler.instanceName: "scheduler"
org.quartz.scheduler.instanceId: "AUTO"
org.quartz.scheduler.skipUpdateCheck: "true"
org.quartz.threadPool.class: "org.quartz.simpl.SimpleThreadPool"
org.quartz.threadPool.threadCount: "10"
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: "myDS"
org.quartz.jobStore.tablePrefix: "QRTZ_"
org.quartz.jobStore.isClustered: "true"
org.quartz.dataSource.myDS.driver: "org.postgresql.Driver"
org.quartz.dataSource.myDS.URL: "jdbc:mysql://localhost:3306/quartz"
org.quartz.dataSource.myDS.user: user
org.quartz.dataSource.myDS.password: pass
org.quartz.dataSource.myDS.maxConnections: "5"
org.quartz.dataSource.myDS.validationQuery: "select 1"

这是我看到的一个例外

使用yaml格式，但是，当您使用纯属性格式时，不应该将值括在引号中

因此，在您的例子中，它确实找不到类
“org.quartz.siml.SimpleThreadPool”
，因为有引号

我建议对quartz配置使用主dropwizard配置（yaml）（正如库文档所建议的那样），以便将所有配置保持在一个位置
