小编San*_*isy的帖子

我不知道这个错误意味着什么.我,正在使用visual studio for mac 7.5.0社区版.从我开始,我在asp.net核心的实体框架中使用延迟加载.

public partial class AdminUser
{
    public AdminUser()
    {
        RoleAssign = new HashSet<RoleAssign>();
    }

    public Guid UserId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string UserName { get; set; }
    public byte[] Password { get; set; }
    public DateTime CreatedTimeStamp { get; set; }
    public DateTime? ModifiedTimeStamp { get; set; }
    public DateTime? LogDate { get; set; …

如何<img> src在Angular 2中编写ternany条件.

下面是我尝试的代码,但这不起作用

<img class="lib-img" [src]="item.pictureUrl!= null ? item.pictureUrl : ~/images/logo.png" height="500" width="500" alt="default image">

我正在尝试在 mac os webapi 上使用asp.net core 2.1调用视图或存储过程。

using System;
using System.Linq;
using Auth.Database;
using Microsoft.EntityFrameworkCore;

public virtual IQueryable<T> ExecuteStoreProcView(string viewProcName)
{
    IQueryable<T> queryResult = _entities.Set<T>().FromSql(viewProcName).AsQueryable();
    return queryResult;
}

得到以下错误

错误 CS1061：“DbSet”不包含“FromSql”的定义，并且找不到接受“DbSet”类型的第一个参数的扩展方法“FromSql”（您是否缺少 using 指令或程序集引用？）(CS1061)

我正在 mac os 上使用实体框架开发 webapi。

研究以下链接中的一些查询：- 没有 DbSet 的原始 SQL 查询 - Entity Framework Core

但无法找到错误解决方案。任何人都可以请让我知道我缺少什么。

刚刚尝试使用 jdk17 创建 Gradle 项目，面临以下问题。我知道 JDK 17 需要 Gradlew 7.3，但不太确定应该从哪里设置 Gradle 的版本

摇篮位置

摇篮版本

我正在将角度应用程序迁移到standalone component. 删除了ngModule和app.module.ts文件

主要.ts

bootstrapApplication(AppComponent,{\n  providers:[importProvidersFrom(FalconCoreModule.forRoot(environment)),\n             importProvidersFrom(RouterModule.forRoot(routes))]\n}).catch(err => console.error(err));\n

应用程序组件.scss

@Component({\n  selector: 'app-root',\n  templateUrl: './app.component.html',\n  styleUrls: ['./app.component.scss'],\n  standalone: true,\n  imports:[RouterModule,FalconCoreModule]\n})\nexport class AppComponent {}\n

自动完成.component.ts

@Component({\n  selector: 'app-auto-complete',\n  templateUrl: './auto-complete.component.html',\n  styleUrls: ['./auto-complete.component.scss'],\n  standalone: true,\n  imports:[FalconCoreModule,CodeGeneratorComponent,HighlightModule,CodeButtonComponent]\n})\nexport class AutoCompleteComponent\n  extends BaseFormComponent<string>\n  implements OnInit {}\n

错误

我正在尝试使用以下代码绑定分页中的类。

<ul class="pagination hidden-xs pull-right">
   <li *ngFor="let pagItem of _pagination">
       <a style="cursor: pointer;"
           (click)="paginationClick($event)"
           id="{{pagItem.pageNo}}"
           [ngClass]="{'active': pagItem.pageNo === currentPage}">
           {{pagItem.pageNo}}
       </a>
   </li>
</ul>

在比较中，我得到了对象对象

这是来自api的响应

Page 和 Id 绑定成功。但是我在类绑定上获取对象对象

这是图像

我的项目中有上面的架构。产品、订单、支付微服务是一个 Rest API，目前具有 swagger 集成，但现在流程发生了变化，我无法公开微服务 Rest API，现在所有 REST API 调用都是从 API 网关进行的。

有没有什么方法可以通过 API 网关以 swagger 方式记录 API，或者这种情况的最佳实践是什么。

这是API Gateway Spring boot中的路由配置

@Bean
    public RouteLocator gatewayRoutes(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(r -> r.path("/order/**")
                        .filters(f -> f.hystrix(option -> option.setName("order-service").
                                setFallbackUri("forward:/orderFallBack")))
                        .uri("lb://ORDER-SERVICE")
                        .id("order-service"))

                .route(r -> r.path("/payment/**")
                        .filters(f -> f.hystrix(option -> option.setName("payment-service")
                                .setFallbackUri("forward:/paymentFallBack")))
                        .uri("lb://PAYMENT-SERVICE")
                        .id("payment-service"))

                .route(r -> r.path("/product/**")
                        .filters(f -> f.hystrix(option -> option.setName("product-service")
                                .setFallbackUri("forward:/productFallBack")))
                        .uri("lb://PRODUCT-SERVICE")
                        .id("product-service"))
                .build();
    }

订单微服务项目中的Swagger配置

@Configuration
public class SwaggerConfiguration {
    @Bean
    public Docket orderApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select() …

寻找更好的解决方案来处理 micronaut 中的全局异常https://docs.micronaut.io/latest/guide/index.html#errorHandling

控制器

@Controller("/category")
public class CategoryController {
@Delete(uri = "/{id}")
public Maybe<HttpResponse> delete(@NotBlank String id) {
            LOG.info(String.format("API --> Deleting the specified category"));
            return iCategoryManager.Count(id).flatMap(item -> {
                if (item > 0) {
                    iCategoryManager.Delete(id).subscribe();
                    return Maybe.just(HttpResponse.noContent());
                } else
                    return Maybe.just(HttpResponse.notFound());
            });
    }
}

iCategoryManager.Count(id)导致如下异常，如何捕获GlobalExceptionHandler上的异常

我使用 Angular 15 和 Angular Material 15，然后按照说明添加了 Tailwind CSS https://tailwindcss.com/docs/guides/angular

材料组件设计不匹配，如下所示

占位符名称被按应有的方式截断

该行出现在文本框中。

在 style.scss 中

@tailwind base;
@tailwind components;
@tailwind utilities;

顺风配置

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{html,ts}",
    ],
  theme: {
    extend: {},
  },
  plugins: [],
}

使用 Intelj 使用最新版本的 Micronaut 创建新应用程序会在构建过程中引发异常。
