对Microsoft.AspNetCore.Diagnostics.HealthChecks的强化和redis，mongodb检查的完善
"HealthChecksUI": {

},public void ConfigureServices(IServiceCollection services)
{
var healthbuild = services.AddHealthChecks();
if (!string.IsNullOrWhiteSpace(mongoDbOptions?.ConnectionString))
healthbuild.AddMongoDb(mongoDbOptions.ConnectionString, tags: new string[] { "mongodb" });//健康检查mongodb
healthbuild.AddRedis($redisconnection, name:$"redisTest")//健康检查redis
//检查其他组件，引用相关nuget即可
services.AddHealthChecksUI();//添加健康检查UI能力
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
application.UseHealthChecks("/health", new HealthCheckOptions()//健康检查服务地址
{
Predicate = _ => true,
ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
});
application.UseHealthChecksUI(s => s.UIPath = "/ui");//健康检查UI地址
application.UseCheck(envPath:"/env",infoPath:"/info");//envPath:应用环境地址；infoPath:应用自身信息地址
}得到以下检查结果，可根据此来判断组件健康程度来做下一步处理
