Spring数据查询导致参数索引超出范围异常

Question

有人可以向我解释查询的以下行为吗？

@Query("select distinct p from PostFeedbackPossibility po INNER JOIN po.post p " +
       "where (upper(po.name) = upper(:possA) ) or exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possB) and poB.post = po.post)" +
       "order by (CASE WHEN upper(po.name) = upper(:possA) and exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possB) and poB.post = po.post) THEN 2 " +
       "WHEN upper(po.name) = upper(:possA) or exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possB) and poB.post = po.post) THEN 1 ELSE 0 END) desc, p.publishTime desc")
    public Page<Post> findPostsByFeedbackPossibilitesName(@Param("possA") String possA,
                                                          @Param("possB") String possB,
                                                          Pageable pageable);

执行findPostsByFeedbackPossibilitesName方法时，将引发以下异常：java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2)

即使我有意向该方法添加四个参数，使其具有与查询参数相同数量的方法参数。我得到了SQLException: Parameter index out of range (5 > number of parameters, which is 2).

@Query("select distinct p from PostFeedbackPossibility po INNER JOIN po.post p " +
            "where (upper(po.name) = upper(:possA) ) or exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possB) and poB.post = po.post)" +
            "order by (CASE WHEN upper(po.name) = upper(:possC) and exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possD) and poB.post = po.post) THEN 2 " +
            "WHEN upper(po.name) = upper(:possE) or exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possF) and poB.post = po.post) THEN 1 ELSE 0 END) desc, p.publishTime desc")
    public Page<Post> findPostsByFeedbackPossibilitesName(@Param("possA") String possA,
                                                          @Param("possB") String possB,
                                                          @Param("possC") String possC,
                                                          @Param("possD") String possD,
                                                          @Param("possE") String possE,
                                                          @Param("possF") String possF,
                                                          Pageable pageable);

但是，当我使用不带CASE子句的原始查询时，它会按预期工作。

@Query("select distinct p from PostFeedbackPossibility po INNER JOIN po.post p " +
       "where (upper(po.name) = upper(:possA) ) or exists (select poB from PostFeedbackPossibility poB where upper(poB.name) = upper(:possB) and poB.post = po.post) order by p.publishTime desc")
    public Page<Post> findPostsByFeedbackPossibilitesName(@Param("possA") String possA,
                                                          @Param("possB") String possB,
                                                          Pageable pageable);

我正在使用spring-boot-starter-data-jpa依赖项。 Spring Boot版本2.1.3。
