parameter translation failed when using Spring @Query to define sql statement

when I define a repository as:

Code:

---

public interface OrganizationRepository extends CrudRepository<Organization, Long> {

        @Query("select o.name from Organization o where o.name like :pattern ")
        List<String> findCompanyName(@Param("pattern") String name);
}

---

and invoke in controller:

Code:

---

@Controller
@RequestMapping("/organization")
public class OrganizationController {

        @Autowired
        private OrganizationRepository organizationRepository;

        @RequestMapping(value="/names", method=RequestMethod.GET)
        public @ResponseBody List<String> getCompanyNameList(@RequestParam String term) throws Exception{
                List<String> companyNames=organizationRepository.findCompanyName(term);
               
                return companyNames;
        }

}

---

at runtime, I get the a debug info like:

Code:

---

2012-02-18 16:35:40,763 DEBUG: select organizati0_.name as col_0_0_ from Organization organizati0_ where organizati0_.name like ? >>> org.hibernate.engine.jdbc.spi.SqlStatementLogger.logStatement(SqlStatementLogger.java:104)
Hibernate: select organizati0_.name as col_0_0_ from Organization organizati0_ where organizati0_.name like ?

---

and can't get the expected result?
:confused:I suppose the sql should be something like:

Code:

---

select organizati0_.name as col_0_0_ from Organization organizati0_ where organizati0_.name like 'abc'

---

where is the problem?
