ring @override nis tom == 統一 false turn post
步驟實現: 1.在index.jsp上點擊 註冊頁面 跳轉到register.jsp（不采用） 2.點擊註冊 <a href="/store/user?method=registUI"></a> 3.在userservlet中編寫一個registUI 方法 請求轉發到 register.jsp即可.
完成註冊：
1.regist
封裝數據
設置id
設置state
設置code
調用service 完成註冊操作
請求轉發 /jsp/msg.jsp
2.userservice中的service
調用dao
發送激活郵件
3.userdao dao 添加一條數據
前端界面
1、<!--/store/WebContent/jsp/index.jsp -- >
<li><a href="${pageContext.request.contextPath}/user?method=registUI">註冊</a></li>
2、<!--/store/WebContent/jsp/register.jsp-->
<form class="form-horizontal" style="margin-top:5px;" action="${pageContext.request.contextPath }/user?method=regist"method="post">
3、增加name屬性
增加過濾器
作用：解決亂碼問題
還需要在web.xml中配置
package com.louis.web.filter; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.Map; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig;import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; import javax.servlet.http.HttpServletResponse; /** * 統一編碼 * @author Administrator * */ public class EncodingFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { // TODO Auto-generated method stub } @Override public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException { //1.強轉 HttpServletRequest request=(HttpServletRequest) req; HttpServletResponse response=(HttpServletResponse) resp; //2.放行 chain.doFilter(new MyRequest(request), response); } @Override public void destroy() { // TODO Auto-generated method stub } } class MyRequest extends HttpServletRequestWrapper{ private HttpServletRequest request; private boolean flag=true; public MyRequest(HttpServletRequest request) { super(request); this.request=request; } @Override public String getParameter(String name) { if(name==null || name.trim().length()==0){ return null; } String[] values = getParameterValues(name); if(values==null || values.length==0){ return null; } return values[0]; } @Override /** * hobby=[eat,drink] */ public String[] getParameterValues(String name) { if(name==null || name.trim().length()==0){ return null; } Map<String, String[]> map = getParameterMap(); if(map==null || map.size()==0){ return null; } return map.get(name); } @Override /** * map{ username=[tom],password=[123],hobby=[eat,drink]} */ public Map<String,String[]> getParameterMap() { /** * 首先判斷請求方式 * 若為post request.setchar...(utf-8) * 若為get 將map中的值遍歷編碼就可以了 */ String method = request.getMethod(); if("post".equalsIgnoreCase(method)){ try { request.setCharacterEncoding("utf-8"); return request.getParameterMap(); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } }else if("get".equalsIgnoreCase(method)){ Map<String,String[]> map = request.getParameterMap(); if(flag){ for (String key:map.keySet()) { String[] arr = map.get(key); //繼續遍歷數組 for(int i=0;i<arr.length;i++){ //編碼 try { arr[i]=new String(arr[i].getBytes("iso8859-1"),"utf-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } } flag=false; } //需要遍歷map 修改value的每一個數據的編碼 return map; } return super.getParameterMap(); } }
<filter>

後臺servlet
package com.louis.web.servlet; import java.io.IOException; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * 和用戶相關的servlet */ public class UserServlet extends BaseServlet { public String add(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("userServlet的add方法執行了"); return null; }
/*跳轉到註冊頁面*/ public String registUI(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException { return "/jsp/register.jsp"; }
}
完成註冊
package com.louis.web.servlet; import java.io.IOException; import java.util.Date; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.commons.beanutils.BeanUtils; import org.apache.commons.beanutils.ConvertUtils; import com.louis.domain.User; import com.louis.myconvertor.MyConverter; import com.louis.service.UserService; import com.louis.service.impl.UserServiceImpl; import com.louis.utils.UUIDUtils; /** * 和用戶相關的servlet */ public class UserServlet extends BaseServlet { public String add(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("userServlet的add方法執行了"); return null; } //調轉到註冊頁面 public String registUI(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { return "/jsp/register.jsp"; } //完成註冊 public String regist(HttpServletRequest request,HttpServletResponse response) throws Exception { //1封裝數據 User user = new User(); //註冊自定義轉化器 ConvertUtils.register(new MyConverter(), Date.class); BeanUtils.populate(user, request.getParameterMap()); //1.1設置用戶id user.setUid(UUIDUtils.getId()); //1.2設置激活碼 user.setCode(UUIDUtils.getCode()); //2調用service完成註冊 UserService service = new UserServiceImpl(); service.regist(user); //頁面請求轉發 request.setAttribute("msg", "用戶已註冊，請去郵箱激活"); return "/jsp/msg.jsp"; } }
package com.louis.domain; import java.util.Date; public class User { /** * */ private String uid; private String username; private String password; private String name; private String email; private String telephone; private Date birthday; private String sex; private Integer state = 0;// 激活狀態 1:激活 0:未激活 private String code; public String getUid() { return uid; } public void setUid(String uid) { this.uid = uid; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getTelephone() { return telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public Integer getState() { return state; } public void setState(Integer state) { this.state = state; } public String getCode() { return code; } public void setCode(String code) { this.code = code; } }
action,service,servelt之間的調用關系

問題
註意：
封裝數據的時候報了一個錯誤 是因為 字符串裝成時間類型的是出現錯誤 BeanUtils不支持字符串裝成時間 解決方案: 自定義轉化器 1.編寫一個類 實現Conventer接口 2.實現方法 convert(轉換成的類型,前臺頁面傳入的字符串) 3.註冊轉化器 在封裝數據之前註冊 ConvertUtils.register(new MyConventer(), Date.class);
