JavaWeb项目-人口普查系统

项目需求：

开展第七次全国人口普查，将为编制“十四五”规划提供重要信息支持；推动实现人口与经济社会、资源环境协调发展，为深化供给侧结构性改革，推动经济高质量发展，建设现代化经济体系提供强有力的支持；人口普查还将为完善人口发展战略和政策体系，促进人口长期均衡发展提供重要信息支持。

主页面：

显示人口登记、修改人口信息、删除人口信息、查询人口信息，人口信息浏览五个子菜单。

人口登记页面：

①完成添加人口信息登记，基本信息和填报限制如下表所示

户 别	家庭户 集体户（单选框）
住房类型	家庭住宅、集体住所、工作地住所、其他住宅、无住宅（单选框）
本户现住房面积	XXXXX平方米（文本框，只能输入这个整数）
本户现住房间数	XXXXX间（文本框，只能输入这个整数）
户主姓名	XXXXX（文本框）
身份证号码	XXXXXXXXXXXXXXXXXX（判断身份证位数18位并且只能录入数字、最后一位可以录入X）
性别	男/女（单选框）
民族	（文本框）
受教育程度	研究生、大学本科、大学专科、高中、初中、小学、未上过学（下拉框实现）

 

②点击“提交”按钮，保存成功则跳转到人口基本信息浏览界面，新录入的信息置顶显示。失败则提示错误信息，返回当前页面

修改人口信息页面：

输入户主姓名，显示其余信息，可对身份证号码、性别、民族、受教育程度进行修改。（身份证号码、性别、受教育程度必须符合录入要求）；如果该名户主信息数据库不存在，则提示“该户主信息不存在”。（3分）

删除人口信息页面：

录入户主姓名，显示详细信息后，点击“删除”按钮，弹出提示框，提示“是否确认删除该户主信息”，确认后删除该信息。

浏览人口信息页面：

以列表形式显示人口基本信息，结果列表中显示姓名、性别，民族、受教育程度基本信息，点击姓名，可以跳转到个人详细信息。

查询人口信息页面：

要求可以根据姓名、性别、民族、受教育程度四种条件实现模糊查询，输出结果以列表形式显示，显示姓名、性别、民族、受教育程度基本信息，点击列表中的姓名，跳转到人口个人详细信息页面。
