controller层 UserServlet.java
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
//1.获取数据
String username=request.getParameter("username");//用户名
String password=request.getParameter("password");//密码
String confirm_password=request.getParameter("confirm_password");//确认密码
String real_name = request.getParameter("real_name");//真实姓名
String sex=request.getParameter("sex");//性别
String province = request.getParameter("province");//省份
String city = request.getParameter("city");//城市
String cert_type = request.getParameter("cert_type");//证件类型
String cert = request.getParameter("cert");//证件号码
String birthday_date=request.getParameter("birthday");//出生日期
String user_type = request.getParameter("user_type");//旅客类型
String content = request.getParameter("content");//备注
String agree = request.getParameter("agree");//是否同意on/null 被选中/非选
得到咯值之后需要设置值而需要转换类型
Users user = new Users();
user.setUsername(username);//用户名
user.setPassword(Md5Utils.md5(password));//密码
user.setRule("2");//用户类型 2为普通用户
user.setRealname(real_name);//真实姓名
user.setSex(sex.charAt(0));//性别 String 转 Character
City c = new City();
c.setCityId(city);
user.setCity(c);//获取城市 String 转 引用类型
user.setCerttype(new CertType(Integer.parseInt(cert_type), null));//证件类型 String 转 引用类型
user.setCert(cert);//证件号码
try {
user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse(birthday_date));
} catch (ParseException e) {
e.printStackTrace();
}//出身日期 String 转 date
user.setUsertype(new UserType(Integer.parseInt(user_type), null));//旅客类型 String 转 引用类型
user.setContent(content);//备注
user.setLoginIp(request.getRemoteAddr());//设置IP
结论
String 转 引用类型的两种方法：
第一种：
City c = new City();
c.setCityId(city);
user.setCity(c);//获取城市 String 转 引用类型
第二种：
user.setCerttype(new CertType(Integer.parseInt(cert_type), null));//证件类型 String 转 引用类型
拓展知识点
String转日期类型
try {
user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse(birthday_date));
} catch (ParseException e) {
e.printStackTrace();
}//出身日期 String 转 date
