HQL 意外的 AST 节点：意外的 AST 节点：

Question

我遇到了这个异常：

unexpected AST node: query

我的查询是：

SELECT  u.user_id, u.username,u.email,u.phone,u.status,r.rolename 
FROM user_registration u, roles r 
WHERE u.user_id=r.role_id IN (
    select ur.role_id  from roles ur where ur.role_id=u.user_id
)

此查询在 MySQL 中运行，但在我的应用程序中不起作用

例外是：

SEVERE: Servlet.service() for servlet [spring] in context with path [/jaga] threw exception [Request processing failed; nested exception is org.hibernate.hql.ast.QuerySyntaxException: unexpected AST node: in near line 1, column 196 [SELECT  u.user_id, u.username,u.email,u.phone,u.status,r.rolename FROM com.jagahunt.admin.usermanagement.entity.User u, com.jagahunt.admin.usermanagement.entity.Role r WHERE u.user_id=r.role_id  IN (select ur.role_id  from com.jagahunt.admin.usermanagement.entity.Role ur where ur.role_id=u.user_id)]] with root cause

Answer 1

这是您尝试执行的本机查询。

因此，您应该为此使用 session.createSQLQuery()，而不是采用 HQL 实体查询的 session.createQuery()。
