JSP用过滤器解决request getParameter中文乱码问题.docx
这段代码主要是在进行Java Web开发中,向数据库中插入一条酒店预订信息的操作。具体解释如下:
```java
// 通过request.getParameter()方法获取前端页面传递过来的参数并存储在对应的变量中
String jiudianmingcheng=request.getParameter("jiudianmingcheng");
String kefangbianhao=request.getParameter("kefangbianhao");
String jiage=request.getParameter("jiage");
String yudingshijian=request.getParameter("yudingshijian");
String yudingtianshu=request.getParameter("yudingtianshu");
String nindexingming=request.getParameter("nindexingming");
String nindedianhua=request.getParameter("nindedianhua");
String nindeshenfenzheng=request.getParameter("nindeshenfenzheng");
String beizhu=request.getParameter("beizhu");
String yonghuming=request.getParameter("yonghuming");
// 构建 SQL 语句,将获取到的参数插入到数据库表 jiudianyuding 中
String sql="insert into jiudianyuding(jiudianmingcheng,kefangbianhao,jiage,yudingshijian,yudingtianshu,nindexingming,nindedianhua,nindeshenfenzheng,beizhu,yonghuming) values('"+jiudianmingcheng+"','"+kefangbianhao+"','"+jiage+"','"+yudingshijian+"','"+yudingtianshu+"','"+nindexingming+"','"+nindedianhua+"','"+nindeshenfenzheng+"','"+beizhu+"','"+yonghuming+"') ";
// 执行 SQL 语句,将数据插入到数据库中
connDbBean.executeUpdate(sql);
// 在前端页面弹出提示框,提示操作成功,并跳转到 jiudianxinxilist.jsp 页面
out.print("<script>alert('操作成功!!');location.href='jiudianxinxilist.jsp';</script>");
```
注释已经标在代码中了,主要是通过获取request对象中的参数,构建 SQL 语句并执行插入操作,最后在前端页面弹出提示框并跳转至对应的页面。
