一、新建项目：xxjobDemo

Nuget: 

<PackageReference Include="DotXxlJob.Core" Version="2.3.0" />

            services.AddSingleton<IJobHandler, DemoJobHandler>(); // 添加自定义的jobHandler
            services.AddAutoRegistry(); // 自动注册
            services.AddControllers();
        }
 
        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

            app.UseXxlJobExecutor();
 
            app.UseRouting();
 
            app.UseAuthorization();
