【中文标题】java.lang.IllegalArgumentException：org.hibernate.hql.internal.ast.QuerySyntaxException：新闻未映射[来自新闻，其中状态=：活动]【英文标题】：java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: News is not mapped [from News where status =: active] 【发布时间】：2021-09-05 18:43:50 【问题描述】：我连接了 Spring 5.0.19.RELEASE 和 Hibernate 5.2.10.Final。
我收到一个错误：java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: News is not mapped [from News where status =: active]。
其他请求也会出现同样的错误（例如“来自新闻”）。
应用程序的工作到达 DAO 层并执行来自数据库的查询。 当我尝试从 BD 获取信息并在 Web 应用程序中显示此列表时。 我是 Java 新手。
我尝试了以下选项：
why-org-hibernate-hql-internal-ast-querysyntaxexception-customer-is-not-mapped
Hibernate error - QuerySyntaxException: users is not mapped [from users]
但它不起作用。
我希望在我困惑的情况下得到帮助。
我在 MySQL 中的数据库
CREATE TABLE `news` (
`idnews` int NOT NULL AUTO_INCREMENT,
`title` varchar(200) COLLATE utf8_bin DEFAULT NULL,
`brief` varchar(500) COLLATE utf8_bin DEFAULT NULL,
`content` varchar(5000) COLLATE utf8_bin DEFAULT NULL,
`date` timestamp NULL DEFAULT NULL,
`status` varchar(45) COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`idnews`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_bin

*** 上有很多帖子解决了同样的问题。但是我无法找到一个明确的解决方案。
请帮忙
【问题讨论】：
这是很多材料，但不是专家，我不能说要为minimal reproducible example 留下什么。但要感谢您仔细格式化和编写您的内容！ 为什么要使用“from News where status =: active”（冒号）？ 您的packagesToScan 属性错误。不得包含src.main.java
当我删除“src.main.java.”时，出现异常：org.springframework.beans.factory.BeanCreationException：在 ServletContext 资源中定义名称为“sessionFactory”的 bean 创建错误 [ /WEB-INF/applicationContext.xml]
【参考方案1】：
你可以试试这个：
Query<News> theQuery = currentSession.createQuery("select news from News news where news.status = :active", News.class);
theQuery.setParameter("status", active);
return theQuery.getResultList();
