Question

我正在使用本指南在我的spring-boot java应用程序上初始化firebase admin sdk：https://firebase.google.com/docs/admin/setup

我已经包含了正确的maven依赖

<dependency>
    <groupId>com.google.firebase</groupId>
    <artifactId>firebase-admin</artifactId>
    <version>5.9.0</version>
</dependency>

我尝试使用他们提供的代码段进行初始化，但是当我导入firebase库时，没有任何符号（firebase，auth，FirebaseOptions，GoogleCredentials，FirebaseApp）正在解析。

import java.io.FileInputStream;
import com.google.firebase.*;
import com.google.auth.oauth2.GoogleCredentials;

import org.springframework.context.annotation.Configuration;

@Configuration
public class FirebaseAdminConfig {
    FileInputStream serviceAccount = new 
FileInputStream("path/to/firebase/credentials/");
    FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(GoogleCredentials.fromStream(serviceAccount))
            .setDatabaseUrl("link to database")
            .build();
FirebaseApp.initializeApp(options);
}

我错过了导入声明吗？是否需要一些额外的配置？

Answer 1

在FirebaseAdminConfig类中，您直接粘贴了代码段。您需要先创建一个方法，否则会出现编译错误。

@Configuration
public class FireBaseConfig{
@Bean
    FirebaseApp createFireBaseApp() throws IOException {
    FileInputStream serviceAccount =
            new FileInputStream("pathtojson.json");

    FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(GoogleCredentials.fromStream(serviceAccount))
            .setDatabaseUrl("url")
            .build();

  return  FirebaseApp.initializeApp(options);
}

}

您也可以在应用程序的主类中进行

public static void main(String[] args) throws IOException {
    FileInputStream serviceAccount = new FileInputStream("src/main/resources/credential.json");
    @SuppressWarnings("deprecation")
    FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(GoogleCredentials.fromStream(serviceAccount))
            .build();
    FirebaseApp.initializeApp(options);
    SpringApplication.run(MarketingDashboardApplication.class, args);
}
