Quartz.Net系列（十六）：通过Plugins模式使用Xml方式配置Job和Trigger和自定义LogPrivider

1.简单介绍

Quarz.Net中采用插件式来实现配置文件配置，通过XMLSchedulingDataProcessor类进行Xml数据处理

默认配置文件命名：quart_jobs.xml

public const string QuartzXmlFileName = "quartz_jobs.xml";

2.创建配置

首先安装扩展程序：Liquid XML Objects(基于XML的xsd文件创建数据模型)

 新建quartz_jobs.xml文件,选择XML=>Schemas 

 Add

 quartz_jobs.xml

<?xml version="1.0" encoding="utf-8" ?>
<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData">
    <processing-directives>
        <overwrite-existing-data>true</overwrite-existing-data>
    </processing-directives>

    <schedule>
        <job>
            <name>myJob</name>
            <group>aaron</group>
            <description>这是Xml定义的Job</description>
            <job-type>Quartz_Demo.MyJob,Quartz_Demo</job-type>
            <durable>true</durable>
            <recover>true</recover>
            <job-data-map>
                <entry>
                    <key>myKey</key>
                    <value>myValue</value>
                </entry>
            </job-data-map>
        </job>
        <trigger>
            <simple>
                <name>myTrigger</name>
                <description>这是Xml定义的Trigger</description>
                <job-name>myJob</job-name>
                <job-group>aaron</job-group>
                <repeat-count>-1</repeat-count>
                <repeat-interval>1000</repeat-interval>
            </simple>
        </trigger>
    </schedule>
</job-scheduling-data>

安装Quartz.Plugins包

编写代码

            var assemblyName = typeof(Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin).AssemblyQualifiedName;

            var scheduler= await SchedulerBuilder.Create().UseXmlSchedulingConfiguration((options)=>{
                options.SetProperty("quartz.plugin.xml.fileNames", "quartz_jobs.xml");
                options.SetProperty("quartz.plugin.xml.scanInterval", "");
                options.SetProperty("quartz.threadPool.threadCount", "");
            }).Build();

            //System.Collections.Specialized.NameValueCollection collection = new System.Collections.Specialized.NameValueCollection();

            //collection.Add("quartz.plugin.xml.type", assemblyName);

            //collection.Add("quartz.plugin.xml.fileNames","quartz_jobs.xml");

            //collection.Add("quartz.plugin.xml.scanInterval", "10");

            //var factory = new StdSchedulerFactory(collection);

            //var scheduler = await factory.GetScheduler();

            LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());

            await scheduler.Start();

             var metaData=await scheduler.GetMetaData();

            Console.WriteLine(metaData.ThreadPoolSize);

自定义LogPrivider

    public class ConsoleLogProvider : ILogProvider
    {
        public Logger GetLogger(string name)
        {
            Logger loger = (logLevel, messageFunc, exception, formatParameters) =>
            {
                if (logLevel >= LogLevel.Debug && messageFunc != null)
                {
                    Console.WriteLine("[" + DateTime.Now.ToLongTimeString() + "] [" + logLevel + "] " + messageFunc(), formatParameters);
                }
                return true;
            };

            return loger;
        }

        public IDisposable OpenMappedContext(string key, object value, bool destructure = false)
        {
            return null;
        }

        public IDisposable OpenNestedContext(string message)
        {
            return null;
        }
    }
