小编Mac*_*iej的帖子

I have local instance of keylcoak and I am trying to connect my flutter app to it and for that I am following the this tutorial but I got stuck on this redirect_uri issue.

In android's build.gradle I have added the following piece to default config:

  applicationId = 'com.my.example_app'
  manifestPlaceholders = [
        'appAuthRedirectScheme': 'com.my.example_app'
  ]

In the code I have:

    const REDIRECT_URI = 'com.my.example_app://login-callback';
    //some code in between
    final AuthorizationTokenRequest req = AuthorizationTokenRequest(
    CLIENT_ID,
    REDIRECT_URI,
    allowInsecureConnections: true,
    issuer: ISSUER,
    discoveryUrl: …

我陷入尝试从数据库添加身份验证的过程。

这是错误日志：

和我的配置类：

1）AppConfig。

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "kamienica")
public class AppConfig {

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setContentType("UTF-8");
        return viewResolver;
    }

    @Bean
    public MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename("messages");
        return messageSource;
    }

}

2）AppInitializer：

public class AppInitializer implements WebApplicationInitializer …

我从后端收到一组对象，其中包含文本作为字段之一。我希望能够编辑该文本。

到目前为止我有这样的事情：

 <div *ngFor="let speech of speeches; index as i">
      <div class="card">
        <div class="card-header">
          <div class="row">
           //some other input fields
        <div class="card-body">
          <ckeditor [(ngModel)]=speech.content
                    [editor]="editor"
                    name={{i}}
                    required
                    [config]="ckeConfig"
                    debounce="500"
                    (change)="onChange($event)">
          </ckeditor>
        </div>
      </div>
  </div>

当演讲数组达到 30-40 左右时，它可以正常工作，但对于更大的数组，它甚至会导致浏览器崩溃。

有人遇到过这个问题并解决了吗？

我已经用 MySQL 为我的 SpringBoot 应用程序编写了 docker compose。当我最终运行 docker-compose up 时，我收到一个错误：
