Java Hibernate SQLGrammarException:无法准备语句…列“；非「；找不到

我有以下代码：

@Entity
@Table(name = "terminal_admin")
public class TerminalAdmin {
        @ManyToMany(fetch=FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinTable(name = "admin_role", joinColumns = { 
            @JoinColumn(name = "admin_id", nullable = false) }, 
            inverseJoinColumns = { @JoinColumn(name = "role_id", 
                    nullable = false) })
   private Set<AdminRole> adminRoles;
}

terminalAdminService.findAdminByRoles(Arrays.asList(new AdminRole("TERMINAL_MODERATOR"),
                        new AdminRole("MODERATOR"),
                        new AdminRole("SUPERADMIN")))




public List<TerminalAdmin> findAdminByRoles(List<AdminRole> roles) {
        Session session = sessionFactory.getCurrentSession();
        Query query = session.createQuery("from TerminalAdmin where adminRoles in :roles");
        query.setParameter("roles", roles);
        return query.list();
    }

我执行以下代码：

@Entity
@Table(name = "terminal_admin")
public class TerminalAdmin {
        @ManyToMany(fetch=FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinTable(name = "admin_role", joinColumns = { 
            @JoinColumn(name = "admin_id", nullable = false) }, 
            inverseJoinColumns = { @JoinColumn(name = "role_id", 
                    nullable = false) })
   private Set<AdminRole> adminRoles;
}

terminalAdminService.findAdminByRoles(Arrays.asList(new AdminRole("TERMINAL_MODERATOR"),
                        new AdminRole("MODERATOR"),
                        new AdminRole("SUPERADMIN")))




public List<TerminalAdmin> findAdminByRoles(List<AdminRole> roles) {
        Session session = sessionFactory.getCurrentSession();
        Query query = session.createQuery("from TerminalAdmin where adminRoles in :roles");
        query.setParameter("roles", roles);
        return query.list();
    }

如何修复它？

您正在直接尝试按对象进行筛选，我不确定这是否可行。您应该尝试在查询中使用

join

。比如：

from TableAdmin ta left join ta.adminRoles ar where ar.id in :roleIds

并将实际ID作为参数传递。

此查询正在运行：

from TerminalAdmin ta left join ta.adminRoles ar where ar.role in (:roles)

---

对于此查询-

角色

应该是字符串列表

罪魁祸首

非限定属性引用

。找不到它的来源。@redflar3我看到了这一点，但我不知道这是什么意思我猜测发生了错误，因为您要求hibernate比较两个对象（类型为

AdminRoles

）。。不确定hibernate是否能做到。。因此，它将

HQL

中的

adminRoles

描述为

非限定属性ref

。@redflar3如何修复它？您可以尝试使用

join

，如

Danail Alexiev

所述，从TerminalAdmin ta left join ta.adminRoles ar where ar.role in（：roles）您没有提供连接路径
