SimpleThreadPool的Quartz ClassNotFoundException(Quartz ClassNotFoundException for SimpleThreadPool)

 我正在尝试配置一个只能在一个节点上运行的石英调度程序（ https://github.com/spinscale/dropwizard-jobs#using-dropwizard-jobs-in-a-clustered-environment ）。 每当我设置石英spinscale/dropwizard-jobs ，它告诉我无法找到SimpleThreadPool ，即使它是通过spinscale/dropwizard-jobs加载到我的项目中。 加载的版本是quartz-2.2.3 
 

 我正在使用https://github.com/spinscale/dropwizard-jobs将quartz连接到dropwizard项目中。 我正在使用dropwizard 1.0.5，dropwizard-guicey 4.0.1（ https://github.com/xvik/dropwizard-guicey ），spinscale quartz implementation 3.0.0。 
 

 我通过这个例子连接了依赖注入： https ： //github.com/xvik/dropwizard-guicey-examples/tree/master/dropwizard-jobs 
 

 我已将以下文件添加到我的项目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"

 

 这是我看到的例外

I'm trying to configure a quartz scheduler that will only run on one node (https://github.com/spinscale/dropwizard-jobs#using-dropwizard-jobs-in-a-clustered-environment). Whenever I setup the quartz threadpool, it tells me that SimpleThreadPool cannot be found, even though it's loaded in my project via spinscale/dropwizard-jobs. The version loaded in is quartz-2.2.3
 

I'm using https://github.com/spinscale/dropwizard-jobs to integrate quartz into a dropwizard project. I'm using dropwizard 1.0.5, dropwizard-guicey 4.0.1 (https://github.com/xvik/dropwizard-guicey), spinscale quartz implementation 3.0.0.
 

I've hooked up dependency injection via this example here: https://github.com/xvik/dropwizard-guicey-examples/tree/master/dropwizard-jobs
 

And I've added the following file to my project 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"

 

This is the exception I'm seeing

最满意答案

 如果你想制作全height边栏，那么侧边栏将是fixed position ，其余内容将是relative position 。 请检查以下代码段 。 
 

 

 
 
 
  
html{
  box-sizing: border-box;
  height: 100%;
  width: 100%;
}
*,
*:after,
*:before{
  box-sizing: inherit;
}
body{
  margin: 0;
  padding: 0;
}
.full_height{
  background-color: white;
  display: flex;
  flex-direction: column;
}
@media (min-width: 992px){
  .full_height{
    padding-left: 330px;
  }
}
.sidebar{
  background-color: #5c5c5c;
  color: white;
  display: flex;
  flex-direction: column;
  margin-bottom: 30px;
  padding: 20px;
  width: 100%;
}
@media (min-width: 992px){
  .sidebar{
    height: 100%;
    left: 0;
    overflow-x: hidden;
    overflow-y: auto;
    position: fixed;
    top: 0;
    width: 310px;
    z-index: 1030;
  }
}
.main{
  background-color: #009688;
  color: white;
  font-size: 20px;
  margin-bottom: 30px;
  padding: 20px;
  width: 100%;
}
 
  
<div class="full_height">
  <div class="sidebar">Some content</div>
  <div class="main">Some dynamic content</div>
</div>

 检查全宽视图中的代码段 。 所有代码段都是响应式的。 
 


If you want to make full height sidebar then sidebar will be fixed position and rest of the content will be relative position. Please check the below Snippet.

  box-sizing: border-box;
  height: 100%;
  width: 100%;
}

*:after,
*:before{
  box-sizing: inherit;
}
body{
  margin: 0;
  padding: 0;
}
.full_height{
  background-color: white;
  display: flex;
  flex-direction: column;
}
@media (min-width: 992px){
  .full_height{
    padding-left: 330px;
  }
}
.sidebar{
  background-color: #5c5c5c;
  color: white;
  display: flex;
  flex-direction: column;
  margin-bottom: 30px;
  padding: 20px;
  width: 100%;
}
@media (min-width: 992px){
  .sidebar{
    height: 100%;
    left: 0;
    overflow-x: hidden;
    overflow-y: auto;
    position: fixed;
    top: 0;
    width: 310px;
    z-index: 1030;
  }
}
.main{
  background-color: #009688;
  color: white;
  font-size: 20px;
  margin-bottom: 30px;
