如何使用spring添加多个google云数据源

# Google Cloud数据源1的配置
google.datasource1.projectId=your-project-id
google.datasource1.credentialsPath=/path/to/credentials1.json

# Google Cloud数据源2的配置
google.datasource2.projectId=your-project-id
google.datasource2.credentialsPath=/path/to/credentials2.json

@Configuration
public class ApplicationConfig {
  
  @Value("${google.datasource1.projectId}")
  private String datasource1ProjectId;
  
  @Value("${google.datasource1.credentialsPath}")
  private String datasource1CredentialsPath;
  
  @Value("${google.datasource2.projectId}")
  private String datasource2ProjectId;
  
  @Value("${google.datasource2.credentialsPath}")
  private String datasource2CredentialsPath;
  
  @Bean
  @ConfigurationProperties(prefix = "google.datasource1")
  public DataSource datasource1() {
    GoogleCredentials credentials = null;
    try {
      credentials = GoogleCredentials.fromStream(new FileInputStream(datasource1CredentialsPath));
    } catch (IOException e) {
      e.printStackTrace();
    }
    StorageOptions options = StorageOptions.newBuilder().setProjectId(datasource1ProjectId).setCredentials(credentials).build();
    return options.getService();
  }
  
  @Bean
  @ConfigurationProperties(prefix = "google.datasource2")
  public DataSource datasource2() {
    GoogleCredentials credentials = null;
    try {
      credentials = GoogleCredentials.fromStream(new FileInputStream(datasource2CredentialsPath));
    } catch (IOException e) {
      e.printStackTrace();
    }
    StorageOptions options = StorageOptions.newBuilder().setProjectId(datasource2ProjectId).setCredentials(credentials).build();
    return options.getService();
  }
}

@Service
public class MyService {
  
  @Autowired
  private DataSource datasource1;
  
  @Autowired
  private DataSource datasource2;
  
  public void doSomething() {
    // 使用datasource1进行数据操作
    // ...
    
    // 使用datasource2进行数据操作
    // ...
  }
}
