从 ZR.Admin 里面 摘出一部分 作为参考
1.Program.cs
public class Program
{
public static void Main(string[] args)
{
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllersWithViews();
builder.Services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
//消除Error unprotecting the session cookie警告
builder.Services.AddDataProtection()
.PersistKeysToFileSystem(new DirectoryInfo(Directory.GetCurrentDirectory() + Path.DirectorySeparatorChar + "DataProtection"));
builder.Services.AddSession();
builder.Services.AddHttpContextAccessor();
//绑定整个对象到Model上
builder.Services.Configure<OptionsSetting>(builder.Configuration);
builder.Services.AddAppService();
//初始化db
DbExtension.AddDb(builder.Configuration);
//builder.Services.AddMvc(options =>
// {
// options.Filters.Add(typeof(GlobalActionMonitor));//全局注册
// })
// .AddJsonOptions(options =>
// {
// options.JsonSerializerOptions.Converters.Add(new JsonConverterUtil.DateTimeConverter());
// options.JsonSerializerOptions.Converters.Add(new JsonConverterUtil.DateTimeNullConverter());
// });
builder.Services.AddSwaggerConfig();
var app = builder.Build();
InternalApp.ServiceProvider = app.Services;
app.UseSwagger();
//if (builder.Configuration["InitDb"].ParseToBool() == true)
//{
// app.Services.InitDb();
//}
// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Home/Error");
}
//开启访问静态文件/wwwroot目录文件，要放在UseRouting前面
app.UseStaticFiles();
//开启路由访问
app.UseRouting();
app.UseAuthorization();
//开启缓存
app.UseResponseCaching();
//使用全局异常中间件
app.UseMiddleware<GlobalExceptionMiddleware>();
app.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
app.Run();
}
}
这里单独说一下 builder.Services.AddAppService();
2. 添加 静态扩展类 AppServiceExtensions
public static class AppServiceExtensions
{
/// <summary>
/// 注册引用程序域中所有有AppService标记的类的服务
/// </summary>
/// <param name="services"></param>
public static void AddAppService(this IServiceCollection services)
{
//var assemblies = AppDomain.CurrentDomain.GetAssemblies();
string []cls = new string[] { "MjBlog.Repository", "MjBlog.Service" };
foreach (var item in cls)
{
Assembly assembly = Assembly.Load(item);
Register(services, assembly);
}
}
private static void Register(IServiceCollection services, Assembly assembly)
{
foreach (var type in assembly.GetTypes())
{
var serviceAttribute = type.GetCustomAttribute<AppServiceAttribute>();
if (serviceAttribute != null)
{
var serviceType = serviceAttribute.ServiceType;
//情况1 适用于依赖抽象编程，注意这里只获取第一个
if (serviceType == null && serviceAttribute.InterfaceServiceType)
{
serviceType = type.GetInterfaces().FirstOrDefault();
}
//情况2 不常见特殊情况下才会指定ServiceType，写起来麻烦
if (serviceType == null)
{
serviceType = type;
}
switch (serviceAttribute.ServiceLifetime)
{
case LifeTime.Singleton:
services.AddSingleton(serviceType, type);
break;
case LifeTime.Scoped:
services.AddScoped(serviceType, type);
break;
case LifeTime.Transient:
services.AddTransient(serviceType, type);
break;
default:
services.AddTransient(serviceType, type);
break;
}
//Console.WriteLine($"注册：{serviceType}");
}
else
{
//Console.WriteLine($"注册：{serviceType}");
}
}
}
}
3.Service 和 Repository 配置 对应的 生命周期
public interface IBaseRepository<T> : ISimpleClient<T> where T : class, new()
{
// 提供 增删改查 事务等接口
}
public class BaseRepository<T> : SimpleClient<T> where T : class, new()
{
public BaseRepository(ISqlSugarClient context = null) : base(context)
{
// 初始化数据库配置,多租户配置
// 提供基础 增删改查, 事务等执行方法
}
}
/// <summary>
/// 参考地址：https://www.cnblogs.com/kelelipeng/p/10643556.html
/// 标记服务
/// 如何使用？
/// 1、如果服务是本身 直接在类上使用[AppService]
/// 2、如果服务是接口 在类上使用 [AppService(ServiceType = typeof(实现接口))]
/// </summary>
[AttributeUsage(AttributeTargets.Class, Inherited = false)]
public class AppServiceAttribute : System.Attribute
{
public LifeTime ServiceLifetime { get; set; } = LifeTime.Scoped;
public Type ServiceType { get; set; }
public bool InterfaceServiceType { get; set; }
}
public enum LifeTime
{
/// <summary>
/// 每次都不一样(不管是不是同一个web请求)
/// </summary>
Transient,
/// <summary>
/// 同一个web请求周期内 ,为同一个对象; 不同web请求,不同对象
/// </summary>
Scoped,
/// <summary>
/// 单例
/// </summary>
Singleton
}
[AppService(ServiceLifetime = LifeTime.Transient)]
public class SysOperLogRepository : BaseRepository<SysOperLog>
{
// 标注 此仓储 生命周期 是 LifeTime.Transient
}
public interface IBaseService<T> : IBaseRepository<T> where T : class, new()
{
}
public class BaseService<T> : BaseRepository<T> where T : class, new()
{
}
public interface ISysOperLogService
{
public void InsertOperlog(SysOperLog operLog);
public PagedInfo<SysOperLog> SelectOperLogList(SysOperLogDto operLog, PagerInfo pager);
}
/// <summary>
/// 操作日志
/// </summary>
[AppService(ServiceType = typeof(ISysOperLogService), ServiceLifetime = LifeTime.Transient)]
public class SysOperLogService : BaseService<SysOperLog>, ISysOperLogService
{
public SysOperLogRepository sysOperLogRepository;
public SysOperLogService(SysOperLogRepository sysOperLog)
{
sysOperLogRepository = sysOperLog;
}
/// <summary>
/// 新增操作日志操作
/// </summary>
/// <param name="operLog">日志对象</param>
public void InsertOperlog(SysOperLog operLog)
{
}
/// <summary>
/// 查询系统操作日志集合
/// </summary>
/// <param name="operLog">操作日志对象</param>
/// <param name="pager"></param>
/// <returns>操作日志集合</returns>
public PagedInfo<SysOperLog> SelectOperLogList(SysOperLogDto operLog, PagerInfo pager)
{
operLog.BeginTime = DateTimeHelper.GetBeginTime(operLog.BeginTime, -1);
operLog.EndTime = DateTimeHelper.GetBeginTime(operLog.EndTime, 1);
bool isDemoMode = AppSettings.GetAppConfig("DemoMode", false);
if (isDemoMode)
{
return new PagedInfo<SysOperLog>();
}
var list = sysOperLogRepository.GetSysOperLog(operLog, pager);
return list;
}4.再Control中使用的时候, 直接注入使用
public class BlogController : Controller
{
private readonly ISysOperLogService _sysOperLogService;
public BlogController(ISysOperLogService sysOperLogService)
{
_sysOperLogService = sysOperLogService;
}
public IActionResult Index()
{
var sysOperLog =new Model.Models.SysOperLog();
_sysOperLogService.InsertOperlog(sysOperLog);
return View();
}
