Question

我正在使用带有大量条件的hibernate条件查询。查询是否包含由应用程序状态和角色组成的购买请求表单。因此，为了简单起见，所有表单都在状态1或草稿中启动。保存表单后，当前用户将成为创建者。创建者可以将其他用户分配给表单，例如授权人或联系人。这些是我认为的动态角色。所以表格的前三个状态如下：

State 1 "Draft" role Creator
State 2 "Authorizer" role Authorizer
State 3 "Contact" role Contact

一旦离开状态3并进入状态4，应用程序现在进入管理员角色。在表格最终获得批准并结束之前，最多可能有15个州。直到最后四个州，创建者，授权者和联系人将继续访问。最后四个州，他们将无法访问。

除非管理员是创建者，授权者或联系人，否则用户将无法访问前三个状态，但将继续访问最后一个状态，包括其余四个非管理员没有'也可以访问。

我当前的查询如下所示，但作为管理员，我想不必手动硬编码将每个applicationState添加到查询中并添加所有这些，但排除管理员不在的状态在动态角色创建者，授权者或联系人中。

此查询有效，但非常混乱。

Disjunction programRoles = Restrictions.disjunction();
            programRoles.add(Restrictions.eq(Role.ROLE_CREATOR, user));
            programRoles.add(Restrictions.eq(Role.ROLE_AUTHORIZER, user));
            programRoles.add(Restrictions.eq(Role.ROLE_CONTACT, user));

            if(roleManagerService.isAdmin()) {
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.ARCHIVED.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.ASSESSOR_REVIEW.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.ASSIGNOR_REVIEW.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.AUDITOR_REVIEW.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.BURIED.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.DEAD.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.FINAL.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.FINAL_MAJOR_APPROVAL.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.FINAL_MINOR_APPROVAL.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.IFAS_LOAD.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.PO_COLLECTION.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.PO_DISTRIBUTION.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.PO_EVALUATION.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.PURGE.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.SECONDARY_MAJOR_REVIEW.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.SECONDARY_MINOR_REVIEW.name()));
                programRoles.add(Restrictions.eq("currentState.prStateCode", ApplicationStateEnum.SECONDARY_OVERHEAD_REVIEW.name()));
            }

        Criteria results = this.session.createCriteria(PurchaseRequest.class)
                .createAlias("currentState", "currentState")
                .add(programRoles);

                if(!roleManagerService.isAdmin()) {
                    results.add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.DEAD.name()))
                            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.ARCHIVED.name()))
                            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.FINAL.name()))
                            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.BURIED.name()));
                }

我想知道是否有人可以指出我的方向来清理它，使它更有活力。

我还没有真正尝试过，但可能只是添加了管理员用户不允许看到的限制。类似的东西：

Disjunction programRoles = Restrictions.disjunction();
programRoles.add(Restrictions.eq(Role.ROLE_CREATOR, user));
programRoles.add(Restrictions.eq(Role.ROLE_AUTHORIZER, user));
programRoles.add(Restrictions.eq(Role.ROLE_CONTACT, user));

// change starts here
if(roleManagerService.isAdmin()) {
    Conjunction notHiddenStateForAdmin = Restrictions.conjunction();
    notHiddenStateForAdmin.add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.FIRST_STATE.name()));
    notHiddenStateForAdmin.add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.SECOND_STATE.name()));
    notHiddenStateForAdmin.add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.THIRD_STATE.name()));
    programRoles.add(notHiddenStateForAdmin);
}

// rest unchanged
Criteria results = this.session.createCriteria(PurchaseRequest.class)
       .createAlias("currentState", "currentState")
       .add(programRoles);

if(!roleManagerService.isAdmin()) {
     results.add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.DEAD.name()))
            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.ARCHIVED.name()))
            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.FINAL.name()))
            .add(Restrictions.ne("currentState.prStateCode", ApplicationStateEnum.BURIED.name()));
}
