Google App Engine でデータストアを使用しようとしています。オブジェクトを永続化し、ID で取得できます。しかし、私はそれを照会することはできません。
これは私のエンティティです:
package my.company.domain;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable(detachable="true")
public class User {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
long key;
@Persistent
private String name;
@Persistent
private String password;
@Persistent
private boolean adminPrivileges;
//getters & setters
}
そして私のユニットテスト:
public void persistAndFindUserTest(){
User user = new User();
user.setName(johnDoe");
user.setPassword("password");
UserService userService = new DefaultUserService();
user = userService.createUserInDatabase(user);
User userFromPersistence = userService.getUserById(user.getKey());
Assert.assertEquals(user.getName(), userFromPersistence.getName());
Assert.assertNotNull(userService.findUserByName("johnDoe"));
}
findUserByName は次のように定義されています。
public List<User> findUserByEmail(String email){
PersistenceManager persistenceManager = PMF.get()
.getPersistenceManager();
Query q = persistenceManager.newQuery(User.class);
q.setFilter("email == emailParam");
q.declareParameters("String emailParam");
q.setUnique(false);
List<User> results = null;
try {
results = (List<User>) q.execute(email);
} finally {
results = (List<User>)persistenceManager.detachCopyAll(results);
q.closeAll();
}
return results;
}
次の例外が発生します (行 116 は、結果リストをデタッチしようとする場所です)。
