[java] setMaxResults for Spring-Data-JPA annotation?

I am trying to incorporate Spring-Data-JPA into my project. One thing that confuses me is how do I achieve setMaxResults(n) by annotation ?

for example, my code:

public interface UserRepository extends CrudRepository<User , Long>
{
  @Query(value="From User u where u.otherObj = ?1 ")
  public User findByOtherObj(OtherObj otherObj);
}

I only need to return one (and only one) User from otherObj, but I cannot find a way to annotate the maxResults. Can somebody give me a hint ?

(mysql complains :

com.mysql.jdbc.JDBC4PreparedStatement@5add5415: select user0_.id as id100_, user0_.created as created100_ from User user0_ where user0_.id=2 limit ** NOT SPECIFIED **
WARN  util.JDBCExceptionReporter - SQL Error: 0, SQLState: 07001
ERROR util.JDBCExceptionReporter - No value specified for parameter 2

)

I found a link : https://jira.springsource.org/browse/DATAJPA-147, I tried but failed. It seems not possible now? Why is such an important feature not built into Spring-Data?

If I implement this feature manually:

public class UserRepositoryImpl implements UserRepository

I have to implement tons of predefined methods in CrudRepository, this would be terrible.
