java.lang.IllegalArgumentException：未知参数名称：customer

这是我的代码

public List<Equip> getEquipsByCustomer(int customer) {

    return (List<Equip>) sessionFactory.getCurrentSession()
            .getNamedQuery("getEquipsByCustomer")
            .setParameter("customer",customer)
            .list();
}

以及xml文件中的查询

<sql-query name="getEquipsByCustomer">
    <return class="Equip" alias="equip"/>
    <query-param name="customer" type="int"/>
    SELECT e.* FROM request r
    INNER JOIN equip e ON r.equip_id = e.equip_id
    INNER JOIN customer c ON r.customer_id = c.customer_id
    WHERE c.customer_id = :customer;
</sql-query>

我正在使用另一个getNamedQuery方法,但只有这个得到异常,我找不到我做错了什么.有什么我想念的吗？

完全例外
