public interface TimeContentRepository extends JpaRepository<TimeContent,String> {

    @Query(value = "select id,user_id as userId,create_time as createTime " +
            "from time_content where create_time = ?1 and user_id = ?2")
    List<TimeContent> findOnDay(String create_time,String userId);
}

Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: time_content is not mapped

• 注解中写的是HQL，所以查询的是对象，而不是表名

• 改为

public interface TimeContentRepository extends JpaRepository<TimeContent,String> {

    @Query(value = "select id,user_id as userId,create_time as createTime " +
            "from TimeContent where create_time = ?1 and user_id = ?2")
    List<TimeContent> findOnDay(String create_time,String userId);
}

Caused by: org.hibernate.QueryException: No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode 
 +-[IDENT] IdentNode: 'user_id' {originalText=user_id}

• 同样的问题，查询的字段也是对象的成员，不是表的字段
