CloudDatastoreRemoteServiceConfig (Google App Engine API for Java)

com.google.appengine.api.datastore

Class CloudDatastoreRemoteServiceConfig

  • java.lang.Object
    • com.google.appengine.api.datastore.CloudDatastoreRemoteServiceConfig

  • public abstract class CloudDatastoreRemoteServiceConfig
extends java.lang.Object
    User-configurable global properties of Cloud Datastore.

    Code not running in App Engine Standard can use the Cloud Datastore API by making a single call to setConfig(com.google.appengine.api.datastore.CloudDatastoreRemoteServiceConfig) before accessing any other classes from com.google.appengine.api. For example: 

     public static void main(Strings[] args) {
   CloudDatastoreRemoteServiceConfig config = CloudDatastoreRemoteServiceConfig.builder()
       .appId(AppId.create(Location.US_CENTRAL, "my-project-id"))
       .build();
   CloudDatastoreRemoteServiceConfig.setConfig(config);
   DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
   ...
 }
    Outside of tests, the config should not be cleared once it has been set. In tests, the config can be cleared by calling clear(): 
      @Before
 public void before() {
   CloudDatastoreRemoteServiceConfig config = CloudDatastoreRemoteServiceConfig.builder()
       .appId(AppId.create(Location.US_CENTRAL, "my-project-id"))
       .emulatorHost(...)
       .build();
   CloudDatastoreRemoteServiceConfig.setConfig(config);
 }

  @After
 public void after() {
   CloudDatastoreRemoteServiceConfig.clear();
 }
    By default, this configuration uses application-default credentials.
