java 方法JPQL查询验证失败

我正在实现一个查询，该查询返回自定义对象中的输出。在我的实现中，我收到一个错误：
“方法公开摘要java.util.列出组织.级别.存储库.合并响应存储库.事务（）！”
JPQL存储库代码：

@Query(value = "SELECT new org.degs.beans.ConsolidateResDB(DATE_FORMAT(ts, '%d-%m-%Y') AS transdate,IFNULL(COUNT(orderreqid),0),IFNULL(COUNT(failamount),0),IFNULL(SUM(amount),0),IFNULL(SUM(successamount),0),IFNULL(SUM(failamount),0),IFNULL(COUNT(successcount),0)) FROM Consolidateresponse GROUP BY DATE_FORMAT(ts, '%d-%m-%Y') ORDER BY ts DESC")
public List<ConsolidateResDB> transactions();

ConsolidateResDB豆：

public class ConsolidateResDB {
    String transdate;
    long total;
    long failcount;
    double totalamount; double successamount;
    double failamount;
    long successcount;
}

我已经在查询本身中处理了空值，并且如果我在mysql db终端中运行相同的查询，则会获得正常输出，但在JPA和Sping Boot 中实现时仍然收到NullPointerException错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'crRepo'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'consolidateresponseRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List org.degs.repository.ConsolidateresponseRepository.transactions()!

您必须告诉Spring将该查询视为原生查询，否则它将尝试根据JPA规范验证它。
试试看：

@Query(value = "SELECT ...", nativeQuery = true)
public List<Object[]> transactions();

请记住，在这种情况下不能使用NEW运算符语法，您必须将result作为Object数组来处理。

    • 或者**

如果您想使用将结果直接Map到POJO类的方法，则必须执行以下操作（假设您使用的是JPA 2.1+）：

    • 1）**定义Map：
@SqlResultSetMapping(
    name="transactionsMapping",
    classes={
        @ConstructorResult(
            targetClass=ConsolidateResDB.class,
            columns={
                @ColumnResult(name="transdate"),
                @ColumnResult(name="orderreqid")
                // further mappings ...
            }
        )
    }
)
    • 2）**定义本机查询
@NamedNativeQuery(name="transactions"
    , query="SELECT DATE_FORMAT(ts, '%d-%m-%Y') AS transdate, IFNULL(COUNT(orderreqid),0) ... ")
    • 3）**在CrudRepository中定义此方法，不带@Query注解：
public List<ConsolidateResDB> transactions();

对于Spring数据2.0.5及以上，

尝试Maciej的解决方案后，我的代码开始抱怨"Got different size of tuples and aliases".要在最新版本中修复该问题，我们需要添加

@Query(<Entity.FunctionName>, nativeQuery=true).

这使得我的代码可以在e2e环境下工作。

对我来说，它是（嗯，不完全相同的代码，但你得到的想法）：

@Query("SELECT e FROM TheEntity e WHERE e.stuff = :stuff")
List<SomeEntity> findSomething(@Param("stuff") String someStr);

别忘了实体：

@Entity(name = "TheEntity")

我遇到了同样的问题，下面的工作对我来说.

@Query(value = "select NEW org.degs.beans.ConsolidateResDB(DATE_FORMAT(c.ts, '%d-%m-%Y') ,IFNULL(COUNT(c.orderreqid),0),IFNULL(COUNT(c.failamount),0),IFNULL(SUM(c.amount),0),IFNULL(SUM(c.successamount),0),IFNULL(SUM(c.failamount),0),IFNULL(COUNT(c.successcount),0)) FROM Consolidateresponse c GROUP BY DATE_FORMAT(c.ts, '%d-%m-%Y') ORDER BY c.ts DESC") 
public List<ConsolidateResDB> transactions();

我得到了同样的错误，我不想使用本机查询。
已通过删除INNER JOIN子句解决此问题。

// Will not work if relations between entity classes are not defined properly.
  @Query(value = "SELECT d FROM Animal a "
      + "INNER JOIN Dog d ON a.id = d.animalId "
      + "WHERE d.name = ?1")

这是一个工作的。

// Works fine. (NO INNER JOIN)
  @Query(value = "SELECT d FROM Animal a, Dog d "
      + "WHERE a.id = d.animalId "
      + "WHERE d.name = ?1")

在我的例子中，我并没有尝试在自定义对象中返回输出，但是我得到了这个错误，正如问题中所描述的：

Caused by: java.lang.IllegalArgumentException: Validation failed for query 
...
Caused by: java.lang.NullPointerException: null

在我的例子中，我的代码是这样的：

public interface MyRepository extends CrudRepository<MyDAO, MyDAOPK> {
   @Query("select MyDAO from MyDAO")
   List<MyDAO> getAll();
}

我要做的就是删除SELECT。

@Query("from MyDAO")
List<MyDAO> getAll();

感谢this link提供线索。
我还可以在其他地方使用this solution，使用自定义对象返回结果，正如最初的问题所问的那样。
