tbschedule项目其实可以分为两部分：

1. schedule管理控制台。负责控制、监控任务执行状态
2. 实际执行job的客户端程序。

在实际使用时，首先要启动zookeeper, 然后部署tbschedule web界面的管理控制台，最后启动实际执行job的客户机器。这里zookeeper并不实际控制任务调度，它只是负责与N台执行job的客户端通讯，协调、管理、监控这些机器的运行信息。实际分配任务的是tbschedule管理控制台，控制台从zookeeper获取job的运行信息。

tbSchedule通过控制ZNode的创建、修改、删除来间接控制Job的执行，执行Job的客户端会监听它们对应ZNode的状态更新事件，从而达到通过tbSchedule控制Job执行的目的。

部署zookeeper

去http://zookeeper.apache.org/releases.html#download下载最新稳定版本。下载完成后解压，将 /conf目录下的XXX.cfg更名为zoo.cfg，因为zookeeper启动时会在这个目录下找zoo.cfg读取配置信息。这个文件里有几个重要的参数需要说明一下：

• tickTime=2000
  • 定义时间计量单位。这里表示一个tick为2秒。以后在配置时间相关的东西时，都是以tick为单位的。
• dataDir=/tmp 
  • 定义快照(snapshot)文件的存储位置。zookeeper会将节点信息定时写入到这个目录中。这个目录必须存在，否则启动时会报错。
• clientPort=2181 
  • 指定客户端连接端口。 zookeeper会在这个端口监听连接请求。
• server.1=127.0.0.1:2000:3000 
  • 这个参数仅在集群部署时起作用。格式为:server.id=host:port:port。id表示服务器的唯一标识，一般从1开始计数。第一个port表示zookeeper集群机器之间的通讯端口，第二个port表示当集群机器在选举leader时使用的通讯端口。只有当集群第一次启动，或master机崩溃时，才会进行leader选举。

配置完成后，切换到/bin目录，执行：

<code class=" hljs sql" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">./</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">zkServer</span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">.</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">sh </span><span class="hljs-operator" style="box-sizing: border-box; padding: 0px;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box; padding: 0px;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">start</span></span></span></code>

即可启动zookeeper，默认会在后台运行，如果想在前端运行，需要执行：

<code class=" hljs sql" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">./</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">zkServer</span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">.</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">sh </span><span class="hljs-operator" style="box-sizing: border-box; padding: 0px;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box; padding: 0px;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">start</span></span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">-</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">foreground</span></span></code>

Zookeeper集群部署

集群部署时，除了需要指定zoo.cfg中server.X:XXXX:XX:XX参数外，还要在每台机器的dataDir目录下创建一个名为myid的文件，内容为当前机器的标识数字，与server.X中的X相同。完成配置后，依次启动每个zookeeper即可。 
注意，当你在启动第一个zookeeper时控制台会大量报错，这是因为其它的zookeeper还没有启动。无视即可。

tbSchedule控制台部署

tbSchedule就是个用servlet/JSP 写的web项目，我们可以直接把war包部署到tomcat中，然后在浏览器访问

<code class=" hljs cs" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">http</span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">:</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box; padding: 0px;">//localhost:8080/ScheduleConsole</span></code>

即可。 
如果你想手动编译、构建项目而不是使用war包，要小心一个坑，那就是执行

<code class=" hljs lasso" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">mvn clean install </span><span class="hljs-attribute" style="box-sizing: border-box; padding: 0px;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">-</span><span class="typ" style="box-sizing: border-box; padding: 0px; color: rgb(102, 0, 102);">Dmaven</span></span><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box; padding: 0px;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">.</span></span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">test</span><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box; padding: 0px;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">.</span></span><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box; padding: 0px;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">skip</span></span><span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box; padding: 0px;"><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">=</span></span><span class="hljs-literal" style="color: rgb(0, 102, 102); box-sizing: border-box; padding: 0px;"><span class="kwd" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 136);">true</span></span></code>

时maven会报找不到构件的错误。查其原因，是因为这个项目太老了，当时是用maven2构建的，项目中用到的依赖版本也比较老了，而且它们所在的repository已经停用了，因此无法自动下载。解决方法，直接exclusion缺少的依赖即可：

第一次访问控制台时会出现以下配置页面： 

第一行指定zookeeper的地址、端口，第二行是超时时间。用户名和密码在这里没有任何用处，无视即可。要注意的是第三行Zookeeper的根目录，这并不是指的部署zookeeper时指定的dataDir，而是一个你自己指定的、与当前管理控制台在同一个机器上的目录，tbSchedule管理控制台会将任务的配置信息(如执行开始时间，调度策略)保存到该目录下，这样下次启动管理控制台时就可以直接从目录中读取配置信息了。

填写完成后点保存，此时上面会出现一行红字，无视之。直接点击管理主页即可进入管理页面： 

至此tbSchedule控制台部署完毕。

tbSchedule客户端编写

tbSchedule项目的test/目录下有很多测试类，可以执行

<code class=" hljs " style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">mvn test</span></code>

把测试跑一遍。跑之前要修改项目中schedule.xml文件正确填写zookeeper的连接地址。测试跑通则说明tbSchedule管理控制台和zookeeper都部署无误。

当我们要执行一个job时，需要创建新项目，引入tbschedule依赖，实现指定接口，然后打成jar包，通过

<code class=" hljs avrasm" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: Arial, Helvetica, sans-serif;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background: transparent;"><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">java </span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">-</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">jar </span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">你的</span><span class="pln" style="box-sizing: border-box; padding: 0px; color: rgb(0, 0, 0);">jar</span><span class="pun" style="box-sizing: border-box; padding: 0px; color: rgb(102, 102, 0);">名</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box; padding: 0px;"><span class="pun" style="color: rgb(102, 102, 0); box-sizing: border-box; padding: 0px;">.</span><span class="pln" style="color: rgb(0, 0, 0); box-sizing: border-box; padding: 0px;">jar</span></span></code>

执行这个方法后，你的程序就会向zookeeper发起连接，注册当前机器，请求任务队列，最后根据调度配置执行job。 
job的执行代码需要配置成一个spring bean:

其中泛型参数Passport是我们自定义的类。

tbSchedule的调用流程为：

1. 执行selectTasks()方法，该方法返回一个List对象，表示你选择出的任务列表。
2. 执行execute()方法，tbschedule会遍历你在selectTasks()方法中返回的List，然后对每一个元素都调用execute()方法。

任务调度的配置

进入tbSchedule管理控制台，创建一个新策略： 

注意，任务名称格式为创建的任务名$自定义字符串。其中你自定义的字符串会被传递到selectTasks()方法中的ownSign参数中。

任务管理 -> 创建新任务： 

这是对单个job的调度配置信息。 
重要参数说明：

• 任务名称
  • 就是刚才在配置策略时填写的名称($之前的部分)。
• 处理模式 
  • SLEEP模式
    • 当某一个线程任务处理完毕，从任务池中取不到任务的时候，检查其它线程是否处于活动状态。如果是，则自己休眠； 如果其它线程都已经因为没有任务进入休眠，当前线程是最后一个活动线程的时候，就调用业务接口，获取需要处理的任务，放入任务池中， 同时唤醒其它休眠线程开始工作。
  • NOTSLEEP模式 
    • 当一个线程任务处理完毕，从任务池中取不到任务的时候，立即调用业务接口获取需要处理的任务，放入任务池中。
• 任务项 
  • 一个线程组(会有多个线程)只执行一个任务。
  • 一个任务项只能由一个任务处理器执行
  • 任务处理器是一个逻辑性的概念，一个任务处理器只有一个线程组。
  • 所以可以把任务划分为1,2,3,4,5,6,7,8, 9, 10一共10个任务碎片，10个任务碎片会被分配到10(刚才在创建调度策略中配置的)个线程组，那么每个线程组对应1个任务碎片，运行时任务项参数又被传递到bean任务类selectTasks方法的List queryCondition参数，例如第1个线程组调用selectTasks方法是queryCondition参数条件为1 ，第2个线程组执行参数条件为2。 我们需要在方法中自己解析这个数值，根据值的不同执行不同部分的任务。因为一个线程组会有多个线程，因此可以实现并行计算。

执行job

完成以上工作后，运行编写的job客户端，job即可被调度执行。
