I'm developing Spring MVC + Spring-data-jpa + querydsl to which I'm newbie. When I write a code for querydsl (before that code was working fine), when I added querydsl related code, I started getting the following error not sure what's going wrong. Please guide.

The error for reference: 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'visitRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List com.journaldev.spring.repository.VisitRepository.findByVisitType()!

Ok, I got the solution for this. I should not be using Table name, it should be always Model/Entity name. This (@Query("SELECT v FROM Visit v WHERE v.visitType='NEW'")) resolves problem.

@Repository
public interface VisitRepository extends JpaRepository<Visit, Integer>,
        QueryDslPredicateExecutor<Visit>{
    List<Visit> findByVisitType(String visitType);

    @Query("SELECT v FROM Visit v WHERE v.visitType='NEW'")
    List<Visit> findByVisitType();
}

People who are still getting error even after trying above methods can try this (this solved my problem)

@Query(value = "normal Sql query", nativeQuery=true).

specify value and nativeQuery

I had a very similar problem; my query was :

select fa from FlexAllowanceSnapshot s where s.employeeId=:employeeId

, which should have been:

select fa from FlexAllowanceSnapshot fa where fa.employeeId=:employeeId

One has to bear in mind it's not SQL but HQL, so the syntax and rules are slightly different.

hibernate.cfg.xml file should have the mapping for the tables like below. Check if it is missing in your file.

......
<hibernate-configuration>
......
......
  <session-factory>
......
<mapping class="com.test.bean.dbBean.testTableHibernate"/>
......
 </session-factory>

</hibernate-configuration>
.....
