1. 确保已经正确安装了Angular CLI并升级到最新版本。
2. 安装Keycloak的依赖项和@types/keycloak-js。
3. 在app.module.ts文件中导入KeycloakService。

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { KeycloakService } from 'keycloak-angular';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
  ],
  providers: [
    KeycloakService,
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

4. 在app.component.ts文件中注入KeycloakService并初始化。

import { Component } from '@angular/core';
import { KeycloakService } from 'keycloak-angular';
import { environment } from 'src/environments/environment';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private keycloakService: KeycloakService) {
    this.keycloakService.init({
      config: {
        url: environment.keycloakUrl,
        realm: environment.keycloakRealm,
        clientId: environment.keycloakClientId
      },
      initOptions: {
        onLoad: 'check-sso',
        checkLoginIframe: false
      },
      enableBearerInterceptor: true,
      bearerExcludedUrls: ['/assets', '/clients/public']
    });
  }
}

5. 确保在项目的angular.json文件中正确配置了应用程序的构建选项。以下是一个示例angular.json片段，包括有关构建选项的示例：

  "projects": {
    "my-app": {
      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/my-app",
            "index": "src/index.html",
            "main": "src/main.ts",
            "tsConfig": "tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.scss"
            ],
            "scripts": [],
            "fileReplacements": [
              {
                "replace": "src/environments/environment.ts",
                "with": "src/environments/environment.prod.ts"
              }
            ],
            "polyfills": "src/polyfills.ts",
          },
          ...
        }
      }
    }
  }

6. 构建应用程序。
