我正在Firestore上尝试POC。我已阅读Firebase文档并了解如何初始化，添加和读取数据。我已经设置了一个项目，并将以下依赖项添加到我的pom.xml中：
<dependencies>
<dependency>
<groupId>com.google.firebase</groupId>
<artifactId>firebase-admin</artifactId>
<version>6.6.0</version>
<exclusions>
<exclusion>
<groupId>io.grpc</groupId>
<artifactId>grpc-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- https://mvnrepository.com/artifact/io.grpc/grpc-core -->
<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-core</artifactId>
<version>1.14.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.3</version>
</dependency>
</dependencies>
firebase-admin引用了grpc-core版本1.13.1，而我的项目没有用它构建。因此排除了grpc-core并明确包含1.14.0版本。
这是示例POC代码：
@Component
public class FirestoreSynchronizer {
private static final Logger log = LogManager.getLogger(FirestoreSynchronizer.class);
private String projectId = "xxxxxxxxx";
private String serviceKeyFilePath = "xxxxxxxxx.json";
private Firestore db = null;
private int userIndex = 1;
@PostConstruct
public void initializeFirestore() {
log.debug("Entering initializeFirestore");
try {
InputStream serviceAccountFile = Thread.currentThread().getContextClassLoader().getResourceAsStream(serviceKeyFilePath);
FirebaseOptions options = new FirebaseOptions.Builder()
.setCredentials(GoogleCredentials.fromStream(serviceAccountFile))
.setProjectId(projectId)
.build();
FirebaseApp.initializeApp(options);
db = FirestoreClient.getFirestore();
}
catch (IOException e) {
log.error("Error in initializeFirestore", e);
}
log.debug("Leaving initializeFirestore");
}
public void addDataToFirestore(String collectionName, String docId, Object document) {
log.debug("addDataToFirestore with {}, {}, {}", collectionName, docId, document);
DocumentReference docRef = db.collection(collectionName).document(docId);
//asynchronously write data
ApiFuture<WriteResult> result = docRef.set(document);
// result.get() blocks on response
try {
System.out.println("Update time : " + result.get().getUpdateTime());
}
catch (Throwable t) {
log.error("Error in addDataToFirestore", t);
}
}
public Object readDataFromFirestore(String collectionName, String docId, Class objClass) {
log.debug("readDataFromFirestore with {}, {}, {}", collectionName, docId, objClass);
DocumentReference docRef = db.collection(collectionName).document(docId);
// asynchronously retrieve the document
ApiFuture<DocumentSnapshot> future = docRef.get();
// block on response
DocumentSnapshot document = null;
try {
document = future.get();
}
catch (Throwable t) {
log.error("Error in readDataFromFirestore", t);
}
Object obj = null;
if (document.exists()) {
// convert document to POJO
obj = document.toObject(objClass);
}
else {
log.debug("No document found for given Id : {}", docId);
}
return obj;
}
@Scheduled(cron="0 */2 * * * *" )
public void testFirebaseSync() {
User user = new User();
user.setUserId(userIndex);
user.setName("Name-" + userIndex);
user.setGender("F");
user.setCreationDate(new Date());
log.info("Saving user object to Firestore");
addDataToFirestore("User", String.valueOf(user.getUserId()), user);
log.info("Reading user object from Firestore");
readDataFromFirestore("User", String.valueOf(user.getUserId()), User.class);
userIndex++;
}
}
在Tomcat服务器中运行此命令时，在将数据添加到Firestore时看到以下错误：
