Java 如何使用com.google.appengine.api.datastore.Text

我使用Quercus在google app engine上运行php，并使用下面的代码将值插入GAE数据存储（BigTable）

我对java一无所知。 有人知道如何在我的php代码中使用吗

感谢您不要为“setProperty”的第二个参数传入字符串，而是创建一个新的com.google.appengine.api.datastore.Text并传入

看起来你应该知道怎么做

请参见此处“setProperty”的定义：

这行吗

<?php
import com.google.appengine.api.datastore;
import com.google.appengine.api.datastore.Entity;
import com.google.appengine.api.datastore.DatastoreServiceFactory;
import com.google.appengine.api.datastore.Text;


$entity = new Entity("test"); 
$TextValue = new Text(' --- more than 500 char ---');
$entity->setProperty('story',$TextValue);
$dataService = DatastoreServiceFactory::getDatastoreService();
$dataService->put($entity);
?>

error:
com.caucho.quercus.QuercusException: com.google.appengine.api.datastore.Entity.setProperty: story: String properties must be 500 characters or less. Instead, use com.google.appengine.api.datastore.Text, which can store strings of any length.

<?php
import com.google.appengine.api.datastore;
import com.google.appengine.api.datastore.Entity;
import com.google.appengine.api.datastore.DatastoreServiceFactory;
import com.google.appengine.api.datastore.Text;


$entity = new Entity("test"); 
$TextValue = new Text(' --- more than 500 char ---');
$entity->setProperty('story',$TextValue);
$dataService = DatastoreServiceFactory::getDatastoreService();
$dataService->put($entity);
?>
