1.创建两个包一个是action的一个是model的

在model中写如下两个文件

User.java

内容如下

package com.qbd.model;
import java.io.Serializable;
import java.util.Date;
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private String email;//类型正确 1
private String password;//不为空 1
private String repassword;
private double height;//0.8-2
private String sex;
private String birthday;//类型正确 1
private String name;//不为空在6-20 数字和字母 1
private String bbs;//类型正确 1
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRepassword() {
return repassword;
}
public void setRepassword(String repassword) {
this.repassword = repassword;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBbs() {
return bbs;
}
public void setBbs(String bbs) {
this.bbs = bbs;
}
}

User-Reg-validation.xml

内容如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//Apache Struts//XWork Validator 1.0.3//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
<validators>
<field name="email">
<field-validator type="email" short-circuit="true">
<message>邮箱格式不正确</message>
</field-validator>
</field>
<field name="name">

<param name="expression"><![CDATA[([0-9a-zA-Z]{6,20})]]></param>
<message>必须6-20的字母或数字</message>
</field-validator>
</field>
<field name="bbs" >
<field-validator type="url" short-circuit="true">

<field-validator type="fieldexpression" short-circuit="true">
<param name="expression"><![CDATA[(repassword==password)]]></param>
<message>两次密码不一至</message>
</field-validator>
</field>
<field name="birthday" >
<field-validator type="fieldexpression" short-circuit="true">
<param name="expression"><![CDATA[(\d{4}-\d{1,2}-\d{1,2})]]></param>
<message>日期错误</message>
</field-validator>
</field>
<field name="height" >
<field-validator type="double" short-circuit="true">
<param name="minInclusive">0.8</param>
<param name="maxInclusive">2</param>
<message>身高不再范围</message>
</field-validator>
</field>
</validators>

在action填写

RegisterAction.java

package com.qbd.action;
import com.opensymphony.xwork2.ActionSupport;
import com.qbd.model.User;
public class RegisterAction extends ActionSupport{
private static final long serialVersionUID = 1L;
private User user;
public String execute() throws Exception {
return SUCCESS;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}

RegisterAction-register-validation.xml

内容如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//Apache Struts//XWork Validator 1.0.3//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
<validators>
<field name="user">
<field-validator type="visitor">
<param name="context">Reg</param>
<param name="addpendPrefix">true</param>
<message>用户注册：</message>
</field-validator>
</field>
</validators>

在struts2的配置文件中写

<?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.i18n.encoding" value="UTF-8" />
<package name="default" namespace="/" extends="struts-default">
<interceptors>
<interceptor-stack name="tokenStack">
<interceptor-ref name="token" />
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="tokenStack" />
<action name="register" class="com.qbd.action.RegisterAction">
<result name="invalid.token">error.jsp</result>
<result name="success">success.jsp</result>

<result name="input">register.jsp</result>
</action>
</package>
</struts>
