使用sqlserver搭建高可用雙機熱備的Quartz集羣部署【附源碼】
通常拿Timer和Quartz相比較的，簡直就是對Quartz的侮辱，二者的功能根本就不在一個層級上，如本篇介紹的Quartz強大的集羣機制，能夠採用基於mysql
sqlserver，mysql的集羣方案，固然還能夠在第三方插件的基礎上實現quartz序列化到熱炒的mongodb，redis，震撼力可想而知，接下來本篇就和你們聊git
一聊怎麼搭建基於sqlserver的quartz集羣，實現這麼一種雙機熱備的強大功能。github
一：下載sqlserver版的建表腳本redis
首先你們能夠經過github上搜索quartz的源代碼，在源碼項目的/database/tables目錄下，能夠找到firebird，oracle，mysql，sqlserver等建庫腳本，sql
本篇只需拿取sqlserver版本便可。 https://github.com/quartznet/quartznet/tree/master/database/tables 以下圖所示mongodb
從上面的截圖中能夠看到，我接下來要作的事情就是增長一個你須要建立的database名字，這裏取爲：【quartz】，完整的腳本以下：oracle

二：配置quartz的集羣參數app
當咱們寫var scheduler = StdSchedulerFactory.GetDefaultScheduler()這段代碼的時候，若是你們看過源碼的話，會知道這個GetScheduler的ide
過程當中有一個初始化方法【Instantiate】方法，此方法中你會發如今作DBProvider的時候會須要幾個參數來初始化DB的，好比下面看到的幾個標紅屬性。sqlserver
1 IList<string> dsNames = cfg.GetPropertyGroups(PropertyDataSourcePrefix); 2 foreach (string dataSourceName in dsNames) 3 { 4 string datasourceKey = "{0}.{1}".FormatInvariant(PropertyDataSourcePrefix, dataSourceName); 5 NameValueCollection propertyGroup = cfg.GetPropertyGroup(datasourceKey, true); 6 PropertiesParser pp = new PropertiesParser(propertyGroup); 7 8 Type cpType = loadHelper.LoadType(pp.GetStringProperty(PropertyDbProviderType, null)); 9 10 // custom connectionProvider... 11 if (cpType != null) 12 { 13 IDbProvider cp; 14 try 15 { 16 cp = ObjectUtils.InstantiateType<IDbProvider>(cpType); 17 } 18 catch (Exception e) 19 { 20 initException = new SchedulerException("ConnectionProvider of type '{0}' could not be instantiated.".FormatInvariant(cpType), e); 21 throw initException; 22 } 23 24 try 25 { 26 // remove the type name, so it isn't attempted to be set 27 pp.UnderlyingProperties.Remove(PropertyDbProviderType); 28 29 ObjectUtils.SetObjectProperties(cp, pp.UnderlyingProperties); 30 cp.Initialize(); 31 } 32 catch (Exception e) 33 { 34 initException = new SchedulerException("ConnectionProvider type '{0}' props could not be configured.".FormatInvariant(cpType), e); 35 throw initException; 36 } 37 38 dbMgr = DBConnectionManager.Instance; 39 dbMgr.AddConnectionProvider(dataSourceName, cp); 40 } 41 else 42 { 43 string dsProvider = pp.GetStringProperty(PropertyDataSourceProvider, null); 44 string dsConnectionString = pp.GetStringProperty(PropertyDataSourceConnectionString, null); 45 string dsConnectionStringName = pp.GetStringProperty(PropertyDataSourceConnectionStringName, null); 46 47 if (dsConnectionString == null && !String.IsNullOrEmpty(dsConnectionStringName)) 48 { 49 50 ConnectionStringSettings connectionStringSettings = ConfigurationManager.ConnectionStrings[dsConnectionStringName]; 51 if (connectionStringSettings == null) 52 { 53 initException = new SchedulerException("Named connection string '{0}' not found for DataSource: {1}".FormatInvariant(dsConnectionStringName, dataSourceName)); 54 throw initException; 55 } 56 dsConnectionString = connectionStringSettings.ConnectionString; 57 } 58 59 if (dsProvider == null) 60 { 61 initException = new SchedulerException("Provider not specified for DataSource: {0}".FormatInvariant(dataSourceName)); 62 throw initException; 63 } 64 if (dsConnectionString == null) 65 { 66 initException = new SchedulerException("Connection string not specified for DataSource: {0}".FormatInvariant(dataSourceName)); 67 throw initException; 68 } 69 try 70 { 71 DbProvider dbp = new DbProvider(dsProvider, dsConnectionString); 72 dbp.Initialize(); 73 74 dbMgr = DBConnectionManager.Instance; 75 dbMgr.AddConnectionProvider(dataSourceName, dbp); 76 } 77 catch (Exception exception) 78 { 79 initException = new SchedulerException("Could not Initialize DataSource: {0}".FormatInvariant(dataSourceName), exception); 80 throw initException; 81 } 82 } 83 }
接下來的問題就是這幾個屬性是如何配置進去的，仔細觀察上面代碼，你會發現全部的配置的源頭都來自於cfg變量，ok，接下來你能夠繼續翻看代碼，相信
你會看到有一個Initialize方法就是作cfg變量的初始化，以下代碼所示：
1 public void Initialize() 2 { 3 // short-circuit if already initialized 4 if (cfg != null) 5 { 6 return; 7 } 8 if (initException != null) 9 { 10 throw initException; 11 } 12 13 NameValueCollection props = (NameValueCollection) ConfigurationManager.GetSection(ConfigurationSectionName); 14 15 string requestedFile = QuartzEnvironment.GetEnvironmentVariable(PropertiesFile); 16 17 string propFileName = requestedFile != null && requestedFile.Trim().Length > 0 ? requestedFile : "~/quartz.config"; 18 19 // check for specials 20 try 21 { 22 propFileName = FileUtil.ResolveFile(propFileName); 23 } 24 catch (SecurityException) 25 { 26 log.WarnFormat("Unable to resolve file path '{0}' due to security exception, probably running under medium trust"); 27 propFileName = "quartz.config"; 28 } 29 30 if (props == null && File.Exists(propFileName)) 31 { 32 // file system 33 try 34 { 35 PropertiesParser pp = PropertiesParser.ReadFromFileResource(propFileName); 36 props = pp.UnderlyingProperties; 37 Log.Info(string.Format("Quartz.NET properties loaded from configuration file '{0}'", propFileName)); 38 } 39 catch (Exception ex) 40 { 41 Log.Error("Could not load properties for Quartz from file {0}: {1}".FormatInvariant(propFileName, ex.Message), ex); 42 } 43 44 } 45 if (props == null) 46 { 47 // read from assembly 48 try 49 { 50 PropertiesParser pp = PropertiesParser.ReadFromEmbeddedAssemblyResource("Quartz.quartz.config"); 51 props = pp.UnderlyingProperties; 52 Log.Info("Default Quartz.NET properties loaded from embedded resource file"); 53 } 54 catch (Exception ex) 55 { 56 Log.Error("Could not load default properties for Quartz from Quartz assembly: {0}".FormatInvariant(ex.Message), ex); 57 } 58 } 59 if (props == null) 60 { 61 throw new SchedulerConfigException( 62 @"Could not find <quartz> configuration section from your application config or load default configuration from assembly. 63 Please add configuration to your application config file to correctly initialize Quartz."); 64 } 65 Initialize(OverrideWithSysProps(props)); 66 }
仔細閱讀上面的一串代碼，你會發現，默認quartz參數配置來源於三個地方。
1. app.config中的section節點。
2. bin目錄下的~/quartz.config文件。
3. 默認配置的NameValueCollection字典集合，也就是上一篇博客給你們作的一個演示。
我我的不怎麼喜歡經過quartz.config文件進行配置，這樣也容易寫死，因此我仍是喜歡使用最簡單的NameValueCollection配置，由於它的數據源可來源
於第三方存儲結構中，配置代碼以下：
1 //1.首先建立一個做業調度池 2 var properties = new NameValueCollection(); 3 //存儲類型 4 properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz"; 5 6 //驅動類型 7 properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz"; //數據源名稱 8 properties["quartz.jobStore.dataSource"] = "myDS"; 9 10 //鏈接字符串 11 properties["quartz.dataSource.myDS.connectionString"] = @"server=.;Initial Catalog=quartz;Integrated Security=True"; 12 //sqlserver版本 13 properties["quartz.dataSource.myDS.provider"] = "SqlServer-20"; 14 15 //是否集羣 16 properties["quartz.jobStore.clustered"] = "true"; 17 properties["quartz.scheduler.instanceId"] = "AUTO";
上面的代碼配置我都加過詳細的註釋，你們應該都能看得懂，並且這些配置就是這麼定死的，沒什麼修改的空間，你們記住便可。
三：Job和Trigger定義
在集羣中環境下，job和trigger的定義該怎麼寫的？你們也不要想的太複雜，注意一點就能夠了，在Schedule一個Job時候，經過CheckExists判斷一下
這個Job在Scheduler中是否已經存在了，若是存在，你就不能再次經過Schedule去重複調度一個Job就能夠了。。。因此判斷的代碼也很簡單，以下所示：
1 IScheduler scheduler = factory.GetScheduler(); 2 3 scheduler.Start(); 4 5 var jobKey = JobKey.Create("myjob", "group"); 6 7 if (scheduler.CheckExists(jobKey)) 8 { 9 Console.WriteLine("當前job已經存在，無需調度:{0}", jobKey.ToString()); 10 } 11 else 12 { 13 IJobDetail job = JobBuilder.Create<HelloJob>() 14 .WithDescription("使用quartz進行持久化存儲") 15 .StoreDurably() 16 .RequestRecovery() 17 .WithIdentity(jobKey) 18 .UsingJobData("count", 1) 19 .Build(); 20 21 ITrigger trigger = TriggerBuilder.Create().WithSimpleSchedule(x => x.WithIntervalInSeconds(2).RepeatForever()) 22 .Build(); 23 24 scheduler.ScheduleJob(job, trigger); 25 26 Console.WriteLine("調度進行中！！！"); 27 }
上面這段代碼，你們就能夠部署在多臺機器中了，是否是很簡單？
四：強大的cluster完整演示
全部的初始化工做都作完了，接下來咱們copy一份bin文件，同時打開兩個console程序，以下所示，能夠看到job任務只會被一個console調度，另外
一個在空等待。
而後你確定很好奇的跑到sqlserver中去看看，是否已經有job和trigger的db存儲，很開心吧，數據都有的。。。
、
好了，一切都是那麼完美，接下來能夠展現一下quartz集羣下的高可用啦，若是某一個console掛了，那麼另外一臺console會把這個任務給接過來，實
現強大的高可用。。。因此我要作的事情就是把console1關掉，再看看console2是否是能夠開始調度job了？？？
完美，這個就是本篇給你們介紹的Quartz的Cluster集羣，一臺掛，另外一臺頂住，雙機熱備，固然這些console你能夠部署在多臺機器中，要作的就是保持各
個server的時間同步，由於quarz是依賴於本機server的時間，好了，本篇就先說到這裏吧。
小禮物走一波，雙擊666。。。 完整代碼：SimpleSchedulerApp.zip
