java - 由 : org. hibernate.QueryException 引起:未设置所有命名参数:[isActive] [from User where isActive = :isActive]

Question

我有一个用户表，由活跃用户的 boolean 值组成，如下表所示

id | name | active
1  | john | false
2  | bob  | true
3  | jeff | true

在上面的结构中，我想检索 isActive 等于 true 的用户列表。

这是我的hql查询

public List getByIsActive(boolean isActive) {
        return  getSession().createQuery(
                "from User where isActive = :isActive").list();
    }

我是这样取的

@ResponseBody
    @RequestMapping(value = "/get-all-activeusers", method = RequestMethod.GET)
    public List<User> getAllActiveUsers() {
        try {

            boolean isActive = true;
            return _userDao.getByIsActive(isActive);

        } catch (Exception e) {
            logger.error("Exception in fetching active users: ", e.getStackTrace());
            e.printStackTrace();
        }
        return null;
    }

我收到这个错误

Caused by: org.hibernate.QueryException: Not all named parameters have been set: [isActive] [from User where isActive = :isActive]
    at org.hibernate.internal.AbstractQueryImpl.verifyParameters(AbstractQueryImpl.java:401)
    at org.hibernate.internal.AbstractQueryImpl.verifyParameters(AbstractQueryImpl.java:385)
    at org.hibernate.internal.QueryImpl.list(QueryImpl.java:99)
    at com.models.UserDao.getByIsActive(UserDao.java:64)

请问我在尝试中哪里弄错了。我已经研究过，但它并不适合我面临的问题。

您忘记为命名参数设置参数:更改 dao 方法，如:

public List getByIsActive(boolean isActive) {
        return  getSession().createQuery(
                "from User where isActive = :isActive").setParameter("isActive", isActive)
        .list();
    }
