项目结构如下：

1、新建jsp文件

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@taglib uri="/struts-tags" prefix="s"%><!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><s:form action="login.action" method="post"><s:textfield name="name" label="姓名"></s:textfield><s:textfield name="email" label="邮箱"></s:textfield><s:textfield name="age" label="年龄"></s:textfield><s:textfield name="date" label="日期"></s:textfield><s:submit value="提交"></s:submit></s:form></body></html>

2、新建action文件

/* *@Author swxctx *@time 2016年10月4日 */package com.sw.action;import java.util.Date;import com.opensymphony.xwork2.ActionSupport;public class LoginAction extends ActionSupport {private String name;private String email;private int age;private Date date;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 int getAge() {return age;}public void setAge(int age) {this.age = age;}public Date getDate() {return date;}public void setDate(Date date) {this.date = date;}@Overridepublic String execute() throws Exception {// TODO Auto-generated method stubreturn "success";}}

3、配置web.xml与struts.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>Struts2-test-5-jy</display-name>  <filter>    <filter-name>Struts2-test-5-jy</filter-name>    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>Struts2-test-5-jy</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping></web-app>

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd">    <struts><package name="Strute2-test-5-jy" extends="struts-default"><action name="login" class="com.sw.action.LoginAction"><result name="success">/success.jsp</result><result name="input">/login.jsp</result></action></package></struts>

4、字段有限校验配置文件：

文件命名规则：action名字-validation.xml

LoginAction-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="name"><!-- !NULL --><field-validator type="requiredstring"><message key="name.invalid"></message></field-validator><!-- Length --><field-validator type="stringlength"><param name="minLength">2</param><param name="maxLength">4</param><message>Length:${minLength}-${maxLength}</message></field-validator></field><field name="email"><!-- !NULL --><field-validator type="requiredstring"><message key="email.invalid"></message></field-validator></field><field name="age"><!-- !NULL --><field-validator type="required"><message key="age.invalid"></message></field-validator><!-- Size --><field-validator type="int"><param name="min">0</param><param name="max">150</param><message>Age:${min}-${max}</message></field-validator></field><field name="date"><!-- ！NULL --><field-validator type="required"><message key="date.invalid"></message></field-validator><!-- size --><field-validator type="date"><param name="min">2000-1-1</param><param name="max">2016-10-5</param><message>Date:${min}_${max}</message></field-validator></field></validators>

5、国际化配置文件

package_en_US.properties：

name.invalid=Name cant't be blank!!!
email.invalid=Email cant't be blank!!!
age.invalid=Age cant't be blank!!!
date.invalid=Date cant't be blank!!!

package_ZH_CN.properties：

name.invalid=\u59D3\u540D\u4E0D\u5408\u6CD5
email.invalid=\u90AE\u4EF6\u8F93\u5165\u4E0D\u5408\u6CD5
age.invalid=\u5E74\u9F84\u4E0D\u80FD\u4E3A\u7A7A
date.invalid=\u65E5\u671F\u4E0D\u80FD\u4E3A\u7A7A
