struts2中以xml配置方式对action的所有方法进行校验

来源：互联网发布：电视声音检测软件编辑：程序博客网时间：2024/06/06 01:51

xml文件中的<!CDATA[[]]>问题：

为了避免输入的文本与xml文件中某些特殊字符相冲突可以用<!CDATA[[]]>将文本扣起来，表示此文本是纯文本。如正则表达式<!CDATA[[^1[358]\d{9}$]]>。

案例：

DataValidateAction.java:

package blog.validate;import java.util.Date;import java.util.regex.Pattern;import com.opensymphony.xwork2.ActionSupport;public class DataValidateAction extends ActionSupport {private static final long serialVersionUID = -1817223356525882414L;private String user;private String mobile;private Date birthday;public Date getBirthday() {return birthday;}public void setBirthday(Date birthday) {this.birthday = birthday;}public String getUser() {return user;}public void setUser(String user) {this.user = user;}public String getMobile() {return mobile;}public void setMobile(String mobile) {this.mobile = mobile;}public String execute(){return "success";}public String save(){return "success";}}

DataValidateAction-validation.xml:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE validators PUBLIC        "-//OpenSymphony Group//XWork Validator 1.0.3//EN"        "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd"><validators>    <field name="user">        <field-validator type="requiredstring">        <param name="trim">true</param>            <message>用户名不能为空！</message>        </field-validator>    </field>        <field name="mobile">        <field-validator type="requiredstring">            <message>手机号码不能为空！</message>        </field-validator>        <field-validator type="regex">        <param name="expression"><![CDATA[^1[358]\d{9}$]]></param>        <message>手机号码格式不正确</message>        </field-validator>    </field></validators>

index.jsp:
