hql组合条件查sum的方法

@Query("select sum(r.amount) from RechargeOrder r where 1=1  " +
            "AND (case when (:status is null) then true when(:status=r.status) then true else false end)=true " +
            "AND (case when (:walletType is null) then true when(:walletType=r.walletType) then true else false end)=true " +

            "AND (case when (:userId is null) then true when(:payType=r.userId) then true else false end)=true " +
            "AND (case when (:rechargeType is null) then true when(:rechargeType=r.rechargeType) then true else false end)=true " +
            "AND (case when (:successTimeBegin is null) then true when(:successTimeBegin<=r.successTime) then true else false end)=true " + "AND (case when (:successTimeEnd is null) then true when(:successTimeEnd>=r.successTime) then true else false end)=true " +

            "")
    Integer sumAmount(
            @Param("status")  Integer status
