简易版 用户注册（Struts2）
1.搭建环境
eclipase：Luna Release (4.4.0)
struts2 ：2.3.28 下载地址：http://download.csdn.net/detail/chuck_kui/9513090
2. 创建类
① 创建类
Role类
package com.baidu.struts2.application.onlineusers;
public class Role {
private Integer roleId;
private String roleName;
public Integer getRoleId() {
return roleId;
}
public void setRoleId(Integer roleId) {
this.roleId = roleId;
}
public String getRoleName() {
return roleName;
}
public void setRoleName(String roleName) {
this.roleName = roleName;
}
public Role(Integer roleId, String roleName) {
super();
this.roleId = roleId;
this.roleName = roleName;
}
public Role() {
super();
}
}
Department类
package com.baidu.struts2.application.onlineusers;
public class Department {
private Integer deptId;
private String deptName;
public Integer getDeptId() {
return deptId;
}
public void setDeptId(Integer deptId) {
this.deptId = deptId;
}
public String getDeptName() {
return deptName;
}
public void setDeptName(String deptName) {
this.deptName = deptName;
}
public Department() {
super();
}
public Department(Integer deptId, String deptName) {
super();
this.deptId = deptId;
this.deptName = deptName;
}
}
创建一个DAO
package com.baidu.struts2.application.onlineusers;
import java.util.ArrayList;
import java.util.List;
public class Dao {
private List<Department> departments;
public List<Department> getDepartments(){
departments = new ArrayList<Department>();
departments.add(new Department(1001,"销售部"));
departments.add(new Department(1002,"营运部"));
departments.add(new Department(1003,"教学部"));
return departments;
}
private List<Role> roles;
public List<Role> getRoles(){
roles =new ArrayList<Role>();
roles.add(new Role(2001, "教师") );
roles.add(new Role(2002, "教授") );
roles.add(new Role(2003, "博士生导师") );
return roles;
}
}
参加一个Action
package com.baidu.struts2.application.onlineusers;
import java.util.Map;
import org.apache.struts2.interceptor.RequestAware;
public class Employee implements RequestAware {
Dao dao = new Dao();
private Map<String ,Object> requestMap;
@Override
public void setRequest(Map<String, Object> arg0) {
this.requestMap = arg0;
}
public String input(){
requestMap.put("depts", dao.getDepartments());
requestMap.put("roles", dao.getRoles());
return "input";
}
}
创建一个index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<a href="emp-input">emp-input </a>
</body>
</html>
配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.action.extension" value="action,do,,"></constant>
<package name="default" namespace="/" extends="struts-default">
<action name="emp-*" class="com.baidu.struts2.application.onlineusers.Employee"
method="{1}">
<result name="{1}">/pages/emp-{1}.jsp</result>
</action>
</package>
</struts>
创建emp-input.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<center>
<br><br>
<s:form action="emp-save">
<s:hidden></s:hidden>
<s:textfield name="name" label="Name"></s:textfield>
<s:password name="password" label="Password"></s:password>
<!-- 多选一 也就是单选框 -->
<s:radio name="gender" label="Gender" list="#{'1':'Male','0':'Female'}" ></s:radio>
<!-- 下拉框 -->
<s:select name="dept" label="Department"
list="#request.depts"
listKey="deptId"
listValue="deptName">
</s:select>
<!-- 一组复选框 -->
<s:checkboxlist name="roles" label="Role"
list="#request.roles"
listKey="roleId"
listValue="roleName">
</s:checkboxlist>
<!-- 文本域 -->
<s:textarea name="desc" label="Desc"></s:textarea>
<s:submit></s:submit>
</s:form>
</center>
</body>
</html>
完善 Action
package com.baidu.struts2.application.onlineusers;
import java.util.List;
import java.util.Map;
import org.apache.struts2.interceptor.RequestAware;
public class Employee implements RequestAware {
Dao dao = new Dao();
private String name;
private String password;
private String gender;
private String dept;
private List<String> roles;
private String desc;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getDept() {
return dept;
}
public void setDept(String dept) {
this.dept = dept;
}
public List<String> getRoles() {
return roles;
}
public void setRoles(List<String> roles) {
this.roles = roles;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
private Map<String ,Object> requestMap;
@Override
public void setRequest(Map<String, Object> arg0) {
this.requestMap = arg0;
}
public String input(){
requestMap.put("depts", dao.getDepartments());
requestMap.put("roles", dao.getRoles());
return "input";
}
public String save(){
System.out.println("save: " + this);
return "save";
}
@Override
public String toString() {
return "Employee [name=" + name + ", password=" + password + ", dept="
+ dept + ", gender=" + gender + "]";
}
}
创建接收页面JSP
emp_save.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<center>
<br><br>
Name:${name }
<br><br>
Password:${password }
<br><br>
Gender:${gender }
<br><br>
Dept:${dept }
<br><br>
Roles:${roles }
<br><br>
DESC:${desc }
<br><br>
</center>
</body>
</html>
