2.struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>

	<constant name="struts.custom.i18n.resources" value="message"/>
	<constant name="struts.i18n.encoding" value="UTF-8"/>
	<package name="default" extends="struts-default" namespace="/">
		<action name="regist" class="cn.action.RegistAction" method="regist">
			<result name="success">success.jsp</result>
			<result name="input">index.jsp</result>
		</action>
	</package> 
	
</struts>

3.src目录下的配置文件，共三个

message.properties

register.name=\u7528\u6237\u540D
register.password=\u5BC6\u7801
register.password2=\u786E\u8BA4\u5BC6\u7801

name.null=\u7528\u6237\u540D\u4E0D\u80FD\u4E3A\u7A7A\uFF01
name.length=\u7528\u6237\u540D6\u523010\u4F4D
password.null=\u5BC6\u7801\u4E0D\u80FD\u4E3A\u7A7A\uFF01
password.length=\u5BC6\u7801\u957F\u5EA6\u81F3\u5C116\u4F4D\uFF01
password2.eq=\u786E\u8BA4\u5BC6\u7801\u5E94\u8BE5\u548C\u5BC6\u7801\u76F8\u540C\uFF01

message_en.properties英语

register.name=regist
register.password=password
register.password2=verfypassword

name.null=Name cannot be null
name.length=Name should be between ${minLength} and ${maxLength}
password.null=Password cannot be null
password.length=Mininum password length is ${minLength}
password2.eq=verfypassword and password must be the same!

message_zh_CN.properties

register.name=\u7528\u6237\u540D
register.password=\u5BC6\u7801
register.password2=\u786E\u8BA4\u5BC6\u7801

name.null=\u7528\u6237\u540D\u4E0D\u80FD\u4E3A\u7A7A\uFF01
name.length=\u7528\u6237\u540D6\u523010\u4F4D
password.null=\u5BC6\u7801\u4E0D\u80FD\u4E3A\u7A7A\uFF01
password.length=\u5BC6\u7801\u957F\u5EA6\u81F3\u5C116\u4F4D\uFF01
password2.eq=\u786E\u8BA4\u5BC6\u7801\u5E94\u8BE5\u548C\u5BC6\u7801\u76F8\u540C\uFF01

3.RegistAction.java

package cn.action;

import com.opensymphony.xwork2.ActionSupport;

public class RegistAction extends ActionSupport {

	private String name;
	private String password;
	private String password2;

	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 getPassword2() {
		return password2;
	}

	public void setPassword2(String password2) {
		this.password2 = password2;
	}

	@Override
	public void validate() {
	

	}

	public void validateRegist() {

//		if (name.length() < 6 && name.length() > 15) {
//			addFieldError("name",getText("name.null"));			//用getText方法获得验证
//		}
//		if (password.length() < 6) {
//			addFieldError("password", "用户密码长度不能小于6位");
//		}
//
//		if (!password.equals(password2)) {
//			addFieldError("password2", "两次密码不一致");
//		}
//
//		if (name.length() == 0) {
//			addFieldError("name", "用户名不鞥为空");
//		}
//
//		if (password.length() == 0) {
//			addFieldError("password", "密码不能为空");
//		}
	}

	public String regist() {

		return SUCCESS;
	}

}

4.验证的配置文件，跟action在同一目录下

RegistAction-res-validation.xml第一个要跟action类名相同

<?xml version="1.0" encoding="UTF-8"?>
