Quartz是一个高级的作业管理. 你可以用ABP框架集成Quartz代替默认后台作业管理. 通过这种方式你可以使用相同的后台作业API,将你的代码独立于Quartz. 如果你喜欢也可以直接使用Quartz的API.

使用ABP CLI安装

在项目的文件夹(.csproj文件)中打开命令行窗口输入以下命令:

abp add-package Volo.Abp.BackgroundJobs.Quartz

手动安装

1. 添加 Volo.Abp.BackgroundJobs.Quartz NuGet包添加到你的项目:

Install-Package Volo.Abp.BackgroundJobs.Quartz

2. 添加 AbpBackgroundJobsQuartzModule 到你的模块的依赖列表:

[DependsOn(
    //...other dependencies
    typeof(AbpBackgroundJobsQuartzModule) //Add the new module dependency
    )]
public class YourModule : AbpModule
{
}

配置

Quartz是一个可配置的类库,对此ABP框架提供了 AbpQuartzOptions. 你可以在模块预配置此选项,ABP在初始化Quartz模块时将使用它. 例:

[DependsOn(
    //...other dependencies
    typeof(AbpBackgroundJobsQuartzModule) //Add the new module dependency
    )]
public class YourModule : AbpModule
{
    public override void PreConfigureServices(ServiceConfigurationContext context)
    {
        var configuration = context.Services.GetConfiguration();

        PreConfigure<AbpQuartzOptions>(options =>
        {
            options.Properties = new NameValueCollection
            {
                ["quartz.jobStore.dataSource"] = "BackgroundJobsDemoApp",
                ["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz",
                ["quartz.jobStore.tablePrefix"] = "QRTZ_",
                ["quartz.serializer.type"] = "json",
                ["quartz.dataSource.BackgroundJobsDemoApp.connectionString"] = configuration.GetConnectionString("Quartz"),
                ["quartz.dataSource.BackgroundJobsDemoApp.provider"] = "SqlServer",
                ["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz",
            };
        });
    }
}

从ABP3.1版本开始,我们在 AbpQuartzOptions 添加了 Configurator 用于配置Quartz. 例:

[DependsOn(
    //...other dependencies
    typeof(AbpBackgroundJobsQuartzModule) //Add the new module dependency
    )]
public class YourModule : AbpModule
{
    public override void PreConfigureServices(ServiceConfigurationContext context)
    {
        var configuration = context.Services.GetConfiguration();

        PreConfigure<AbpQuartzOptions>(options =>
        {
            options.Configurator = configure =>
            {
                configure.UsePersistentStore(storeOptions =>
                {
                    storeOptions.UseProperties = true;
                    storeOptions.UseJsonSerializer();
                    storeOptions.UseSqlServer(configuration.GetConnectionString("Quartz"));
                    storeOptions.UseClustering(c =>
                    {
                        c.CheckinMisfireThreshold = TimeSpan.FromSeconds(20);
                        c.CheckinInterval = TimeSpan.FromSeconds(10);
                    });
                });
            };
        });
    }
}

Quartz默认将作业与调度信息存储在内存中,示例中我们使用选项模式的预配置将其更改为存储到数据库中.

默认异常处理策略

当后台作业发生异常时ABP提供了默认异常处理策略,它会为你的作业重试3次,每次间隔3秒. 你可以通过 AbpBackgroundJobQuartzOptions 更改默认重试次数与间隔时间:

[DependsOn(
    //...other dependencies
    typeof(AbpBackgroundJobsQuartzModule) //Add the new module dependency
    )]
public class YourModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpBackgroundJobQuartzOptions>(options =>
        {
            options.RetryCount = 1;
            options.RetryIntervalMillisecond = 1000;
        });
    }
}

自定义异常处理策略

你可以通过 AbpBackgroundJobQuartzOptions 选项自定义异常处理策略:

[DependsOn(
    //...other dependencies
    typeof(AbpBackgroundJobsQuartzModule) //Add the new module dependency
    )]
public class YourModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpBackgroundJobQuartzOptions>(options =>
        {
            options.RetryStrategy = async (retryIndex, executionContext, exception) =>
            {
                // customize exception handling
            };
        });
    }
}
