I have a project where i am calling Google Cloud Storage API from Firebase Cloud FireStore API. This is my Firebase code before adding the Google Cloud Storage dependencies.

This is my main class

package com.example.firebase.springbootfirebasedemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootFirebaseDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootFirebaseDemoApplication.class, args);
    }

}

This is my REST Controller

package com.example.firebase.springbootfirebasedemo.controller;

import com.example.firebase.springbootfirebasedemo.entity.Review;
import com.example.firebase.springbootfirebasedemo.service.ReviewService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;
import java.util.concurrent.ExecutionException;

@RestController
@RequestMapping("/api")
public class ReviewController {

    @Autowired
    private ReviewService reviewService;

    @PostMapping("/reviews")
    public String saveReview(@RequestBody Review review) throws ExecutionException, InterruptedException {

        return reviewService.saveReview(review);
    }

    @GetMapping("/reviews/{name}")
    public Review getReview(@PathVariable String name) throws ExecutionException, InterruptedException {

        return reviewService.getReviewDetailsByname(name);
    }

    @GetMapping("/reviews")
    public List<Review> getAllReviews() throws ExecutionException, InterruptedException {

        return reviewService.getAllReviews();
    }


    @PutMapping("/reviews")
    public String updateReview(@RequestBody Review review) throws ExecutionException, InterruptedException {

        return reviewService.updateReview(review);
    }


    @DeleteMapping("/reviews/{name}")
    public String deleteReview(@PathVariable String name) throws ExecutionException, InterruptedException {

        return reviewService.deleteReview(name);
    }
}

This is my Service class

package com.example.firebase.springbootfirebasedemo.service;

import com.example.firebase.springbootfirebasedemo.entity.Review;
import com.google.api.core.ApiFuture;
import com.google.cloud.firestore.DocumentReference;
import com.google.cloud.firestore.DocumentSnapshot;
import com.google.cloud.firestore.Firestore;
import com.google.cloud.firestore.WriteResult;
import com.google.firebase.cloud.FirestoreClient;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.concurrent.ExecutionException;

@Service
public class ReviewService {

    private static final String COLLECTION_NAME ="Reviews";

    public String saveReview(Review review) throws ExecutionException, InterruptedException {

       Firestore dbFirestore= FirestoreClient.getFirestore();

       ApiFuture<WriteResult> collectionApiFuture=dbFirestore.collection(COLLECTION_NAME).document(review.getName()).set(review);

       return collectionApiFuture.get().getUpdateTime().toString();

    }

    public Review getReviewDetailsByname(String name) throws ExecutionException, InterruptedException {

        Firestore dbFirestore= FirestoreClient.getFirestore();

        DocumentReference documentReference=dbFirestore.collection(COLLECTION_NAME).document(name);

        ApiFuture<DocumentSnapshot> future=documentReference.get();

        DocumentSnapshot document=future.get();

        Review review=null;
        if(document.exists()) {
         review = document.toObject(Review.class);
       return  review;
        }else{
            return null;
        }
    }

    public List<Review> getAllReviews() throws ExecutionException, InterruptedException {

        Firestore dbFirestore= FirestoreClient.getFirestore();

        Iterable<DocumentReference> documentReference=dbFirestore.collection(COLLECTION_NAME).listDocuments();
        Iterator<DocumentReference> iterator=documentReference.iterator();

        List<Review> reviewList=new ArrayList<>();
        Review review=null;

        while(iterator.hasNext()){
            DocumentReference documentReference1=iterator.next();
           ApiFuture<DocumentSnapshot> future= documentReference1.get();
           DocumentSnapshot document=future.get();

            review=document.toObject(Review.class);
           reviewList.add(review);

        }
        return reviewList;
    }


    public String updateReview(Review review) throws ExecutionException, InterruptedException {

        Firestore dbFirestore= FirestoreClient.getFirestore();

        ApiFuture<WriteResult> collectionApiFuture=dbFirestore.collection(COLLECTION_NAME).document(review.getName()).set(review);

        return collectionApiFuture.get().getUpdateTime().toString();

    }

    public String deleteReview(String name) throws ExecutionException, InterruptedException {

        Firestore dbFirestore= FirestoreClient.getFirestore();

        ApiFuture<WriteResult> collectionApiFuture=dbFirestore.collection(COLLECTION_NAME).document(name).delete();

        return "Document with Review ID "+name+" has been deleted successfully";

    }
}

This is my Entity Class

package com.example.firebase.springbootfirebasedemo.entity;

public class Review {

    private String name;
    private String description;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}

This is a class which reads the google service account key

package com.example.firebase.springbootfirebasedemo.firebase;

import com.google.auth.oauth2.GoogleCredentials;
import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

@Service
public class FirebaseInitialization {


    @PostConstruct
    public void initialization(){

        FileInputStream serviceAccount = null;
        try {
            serviceAccount = new FileInputStream("./serviceAccountKey.json");

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

        FirebaseApp.initializeApp(options);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

This is my pom.xml

So far so good. I was able to call my REST API and perform CRUD operation on my Firestore DB. Now i need to call the Google cloud storage API from my Firebase API. For this i added the Google Cloud Storage dependencies.

My new pom.xml after adding the Google cloud storage dependencies.

Now after adding the dependencies and running the server i was getting the following errors.

Please help. Thank you.

What I have tried:

I was able to run CRUD operations without Google cloud storage dependencies. Its only after i add the dependencies, I was getting these errors after trying to run the server.

java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

I was already providing the credentials using google cloud service account key, a JSON file on the context path.

I merely pointed to the error message that explains what is wrong, and how to correct it.

Solution 1

You are (if you can), add again a new database and then enter properly credentials. If again can't work problem is in same application (program - code).
