客户关系管理系统
管理信息系统的开发方法有原型法和面向对象的开发方法等：
原型法的开发思路是首先根据用户的要求，由用户和开发者共同确定系统的基本要求和主要功能，利用系统快速生成工具，建立一个系统模型，再在此基础上与用户交流，将模型不断补充、修改、完善，如此反复，最终直至用户和开发者都比较满意为止，从而形成一个相对稳定、较为理想的管理信息系统。
面向对象的开发方法于20世纪80年代开始兴起的，是一种基于问题对象的自底向上的一种系统开发方法，这种方法的特点是以对象为基础，对象是分析问题和解决问题的核心。
（一）、用户登陆模块
当用户名或者密码任何一个出错系统将会给出信息提示，系统将给出错误信息提示并自动退出系统登陆。
基本代码：
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
HttpSession session = request.getSession();;
String type = request.getParameter("type");
UserDao userDao = new UserDao();
User user = new User();
String message="";
if(type.equals("login")){
String uname = request.getParameter("uname");
String upass = request.getParameter("upass");
user = userDao.getUser(uname);
if(user!=null&&user.getUpass().trim().equals(upass)){
session.setAttribute("user", user);
RequestDispatcher rd=request.getRequestDispatcher("index.jsp");
rd.forward(request,response);
}else{
message="用户名或密码不正确！";
request.setAttribute("message", message);
RequestDispatcher rd=request.getRequestDispatcher("login.jsp");
rd.forward(request,response);
} }
if(type.equals("tzupdatePwd")){
request.setAttribute("mainPage",getInitParameter("tzupdatePwd"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}
（二）、查找客户模块
用户可以按照客户姓名、性别或是客户级别可以对其进行客户信息的搜索查看。
基本编码：
if(type.equals("selectPerson")){
String pid =request.getParameter("pid");
if(pid==null || pid.trim()==""){
List<Person> listAll = personDao.getPerson();
request.setAttribute("listPerson", listAll);
request.setAttribute("mainPage",getInitParameter("selectPerson"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}else{
person = personDao.getPersonById(Integer.parseInt(pid));
if(person==null){
message="该客户ID不存在！";
request.setAttribute("message", message);
request.setAttribute("mainPage",getInitParameter("select"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}else{
List<Person> listP = new ArrayList<Person>();
listP.add(person);
request.setAttribute("listPerson", listP);
request.setAttribute("mainPage",getInitParameter("selectPerson"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}
}
（三)、修改密码模块
该模块对系统合法用户的密码进行修改。在这里需要输入原始密码、新密码和确认密码。
基本编码：
if(type.equals("updatePwd")){
User user1 = new User();
String upass = request.getParameter("newpwd1");
int uid = Integer.parseInt(request.getParameter("uid"));
user1 = userDao.getUserById(uid);
user1.setUpass(upass);
int result = userDao.updatePwd(user1);
if(result>0){
session.setAttribute("user", user1);
message="密码修改成功！";
request.setAttribute("message", message);
request.setAttribute("mainPage",getInitParameter("updatePwd"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}
}
（四)、添加客户信息管理模块
用户输入客户的姓名、性别、年龄、电话、单位进行客户信息的添加。
基本编码：
if(type.equals("addPerson")){
String pname = request.getParameter("pname");
String psex = request.getParameter("psex");
int page = Integer.parseInt(request.getParameter("page"));
String pphone = request.getParameter("pphone");
String paddress = request.getParameter("paddress");
person.setPname(pname);
person.setPage(page);
person.setPsex(psex);
person.setPphone(pphone);
person.setPaddress(paddress);
int result = personDao.addPerson(person);
if(result>0){
message="添加成功！";
request.setAttribute("message", message);
request.setAttribute("mainPage",getInitParameter("add"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}
}
（五)、修改客户信息管理模块
用户输入相关客户信息后查找到客户信息，可以对其修改。
代码如下：
if(type.equals("updatePerson")){
int pid = Integer.parseInt(request.getParameter("pid"));
person = personDao.getPersonById(pid);
if(person==null){
message="该客户ID不存在！";
request.setAttribute("message", message);
request.setAttribute("mainPage",getInitParameter("update"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}else{
request.setAttribute("person", person);
request.setAttribute("mainPage",getInitParameter("updatePerson"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}
}
（六）、查看客户列表模块
在此用户可以查看到所有客户的信息。
代码如下：
if(type.equals("select")){
request.setAttribute("mainPage",getInitParameter("select"));
String forward=this.getServletContext().getInitParameter("indexTemp");
RequestDispatcher rd=request.getRequestDispatcher(forward);
rd.forward(request, response);
}//
（七）、添加用户模块
在线添加新的用户账号和密码。
代码如下：
1.public String addKeHu(){System.out.println("name"+kname);
if(kname.equals("")||kage.equals("")||kphone.equals("")||kjob.equals("")||kzhiwei.equals("")){
String message ="请填写完整在提交！";
Map request=(Map)ActionContext.getContext().get("request");
request.put("message",message);
return "addno";
}else{
Ke ke = new Ke();
ke.setKname(kname);
ke.setKsex(ksex);
ke.setKage(Integer.parseInt(kage));
ke.setKjibie(kjibie);
ke.setKjob(kjob);
ke.setKphone(kphone);
ke.setKzhiwei(kzhiwei);
int count = keService.addKe(ke);
if(count>0){
String message ="添加成功！";
Map request=(Map)ActionContext.getContext().get("request");
request.put("message",message);
return "addok";
}else{
String message ="添加失败！";
Map request=(Map)ActionContext.getContext().get("request");
request.put("message",message);
return "addok";
}
}
}
