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;@Overridepublic 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;@Overridepublic 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";}@Overridepublic 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>

输入：

显示结果：

注意：构造Map 的格式

<s:radio name="gender" label="Gender" list="#{'1':'Male','0':'Female'}" ></s:radio>
