一、概述

实现 IBackgroundWorker 接口，继承 BackgroundWorkerBase 或PeriodicBackgroundWorkerBase

二、使用

2.1 定义

public class MakeInactiveUsersPassiveWorker : PeriodicBackgroundWorkerBase, ISingletonDependency
{
private readonly IRepository<User, long> _userRepository;
public MakeInactiveUsersPassiveWorker(AbpTimer timer, IRepository<User, long> userRepository)
: base(timer)
{
    _userRepository = userRepository;
    Timer.Period = 5000; //5 seconds (good for tests, but normally will be more)
}
[UnitOfWork]
protected override void DoWork()
{
    using (CurrentUnitOfWork.DisableFilter(AbpDataFilters.MayHaveTenant))
    {
        var oneMonthAgo = Clock.Now.Subtract(TimeSpan.FromDays(30));
        var inactiveUsers = _userRepository.GetAllList(u =>
                                        u.IsActive &&);
        foreach (var inactiveUser in inactiveUsers)
        {
              inactiveUser.IsActive = false;
        );
    } 
    CurrentUnitOfWork.SaveChanges();
  }
}

2.2 注册

public class MyProjectWebModule : AbpModule
{
//...
public override void PostInitialize()
{
    var workManager = IocManager.Resolve<IBackgroundWorkerManager>();
    workManager.Add(IocManager.Resolve<MakeInactiveUsersPassiveWorker>());
}
}
