struts2(复合)集合数据校验

来源：互联网发布：网络捕鱼游戏犯法吗编辑：程序博客网时间：2024/06/16 10:02

Action中使用List对象。要在程序中添加一个.properties的配置文件，将List对象指向实体类

1.VisitorListAction.java

package action;import java.util.List;import com.opensymphony.xwork2.ActionSupport;public class VisitorListAction extends ActionSupport{/** *  */private static final long serialVersionUID = 7604066627566749728L;private List<User> user;public List<User> getUser() {return user;}public void setUser(List<User> user) {this.user = user;}@Overridepublic String execute() throws Exception {System.out.println("asd");System.out.println(user.size());return SUCCESS;}}

2.User.java

package action;public class User {private String userName;private int userAge;private String userTelephone;public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public int getUserAge() {return userAge;}public void setUserAge(int userAge) {this.userAge = userAge;}public String getUserTelephone() {return userTelephone;}public void setUserTelephone(String userTelephone) {this.userTelephone = userTelephone;}}

3.User-visitorContext-validation.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.2//EN" "http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd"><validators><field name="userName"><field-validator type="requiredstring"><message>姓名不能为空</message></field-validator></field><field name="userAge"><field-validator type="int"><param name="min">10</param><param name="max">100</param><message>年龄为10-100之间！</message></field-validator></field></validators>

4.VisitorListAction-validation.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.2//EN" "http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd"><validators><!-- 校验字段 --><field name="user"><!-- 校验器 --><field-validator type="visitor"><!-- 复合类型属性的上下文校验名称 --><param name="context">visitorContext</param><!-- 校验信息中输入前缀信息 --><param name="appendPrefix">true</param><message>联系人</message></field-validator></field></validators>

5.VisitorListAction-conversion.properties

Element_user=action.User

其中user表示所定义的List对象，action.User表示实体User类所在的路劲

6.visitorList.jsp

<%@ page language="java" contentType="text/html;charset=gb2312"%><%@ taglib prefix="s" uri="/struts-tags"%><html><head><title>集合类型校验</title></head><STYLE type="text/css">ul.regul,li.regli {list-style: none;float: left;}ul.regul {width: 550px;}li.regli {width: 100px;}</STYLE><body><jsp:include page="index.html"></jsp:include><ul class="regul"><li class="regli">姓名</li><li class="regli">年龄</li><li class="regli">电话</li></ul><s:fielderror></s:fielderror><s:form action="visitorListAction" theme="simple"><s:iterator value="new int[2]" status="st"><ul class="regul"><li class="regli"><s:textfieldname="%{'user['+#st.index+'].userName'}" cssStyle="width:100px;" /></li><li class="regli"><s:textfieldname="%{'user['+#st.index+'].userAge'}" cssStyle="width:100px;" /></li><li class="regli"><s:textfieldname="%{'user['+#st.index+'].userTelephone'}"cssStyle="width:100px;" /></li></ul></s:iterator><br><ul><li style="text-align: left;"><s:submit value="提交"></s:submit></li></ul></s:form></body></html>
