# Quartz 后台作业管理
[Quartz](https://www.quartz-scheduler.net/)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](Background-Jobs.md). 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.
> 参阅[后台作业文档](Background-Jobs.md),学习如何使用后台作业系统. 本文只介绍了如何安装和配置Quartz集成.
## 安装
建议使用[ABP CLI](CLI.md)安装包.
### 使用ABP CLI
在项目的文件夹(.csproj文件)中打开命令行窗口输入以下命令:
````bash
abp add-package Volo.Abp.BackgroundJobs.Quartz
````
### 手动安装
如果你想手动安装;
1. 添加 [Volo.Abp.BackgroundJobs.Quartz](https://www.nuget.org/packages/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:
````csharp
[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:
````csharp
[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:
````csharp
[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);
});
});
};
});
}
}
````
> 你可以选择你喜爱的方式来配置Quaratz.
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](Options.md)的预配置将其更改为存储到数据库中. 有关Quartz的更多配置请参阅[Quartz文档](https://www.quartz-scheduler.net/).
## 异常处理
### 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:
```csharp
[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:
```csharp
[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
};
});
}
}
```
