Jpa 通过枚举查找Spring数据

我遇到了这样的问题，不知道如何解决。下一个问题是： 我有下一个型号：

@Entity(name="Authority")
@Table(name="AUTHORITIES")
public class Authority implements GrantedAuthority {

@Id
private long id;

@Enumerated(EnumType.STRING)
@Column(name="authority")
private asdevelopment.action.enums.Authority authority;

/**
 * 
 */
private static final long serialVersionUID = 1L;

@Override
public String getAuthority() {
    return authority.toString();
}

/**
 * @return the id
 */
public long getId() {
    return id;
}

}


public enum Authority {

CLIENT_ROLE, ADMIN_ROLE;

}

我可以保存权限并通过ID无任何问题。但只要我调用存储库中的下一个方法：

domain.Authority findByAuthority(enums.Authority authority);

我得到下一个例外：

Hibernate: select top ? authority0_.id as id1_, authority0_.authority as authority1_ from AUTHORITIES authority0_ where authority0_.authority=?
13:48:01.125  WARN [main] org.hibernate.engine.jdbc.spi.SqlExceptionHelper:143 - SQL   Error: 1064, SQLState: 42000
13:48:01.125 ERROR [main] org.hibernate.engine.jdbc.spi.SqlExceptionHelper:144 - You    have an error in your SQL syntax; check the manual that corresponds to your MySQL server    version for the right syntax to use near '2 authority0_.id as id1_, authority0_.authority as authority1_ from AUTHORITIES ' at line 1

显然不是MySQL的有效查询

检查您的Hibernate配置。

啊，是的，非常感谢！我把HSQL方言作为一种方言！
