struts2 基于xml校验问题、、求高手看下
package com.struts.user;
public class User {
private String userName;
private String passWord;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
-------------------------
package com.struts2.action;
import com.opensymphony.xwork2.ActionSupport;
import com.struts.user.User;
public class Login extends ActionSupport {
User user;
String result="fail";
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
System.out.println("dddddddddddddddddddddddddd");
if(user.getUserName().equals("java"))
{
System.out.println("dddddddddddddddddddddddddd");
result="success";
}
return result;
}
}

用到的包有、、
commons-fileupload-1.2.1
commons-io-1.3.2
commons-logging-1.0.4
freemarker-2.3.15
ognl-2.7.3
xwork-core-2.1.6
struts2-core-2.1.8
[解决办法]
过滤器文件是Login-login-validation.xml
[解决办法]
第一、确定Login-validation.xml和Login是在同一个包内；
第二、你采用的是Struts2中的拦截器验证，你把Login-validation.xml的文件头改为：
[code=Java][/code]
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
这句话在采用拦截器验证时是不可少的。
你试试以上修改是不是可以 不行的话把报错代码贴上来。
