struts2中以xml配置方式对action的所有方法进行校验

2012-07-24 21:42 169 查看

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:
