使用struts实现登录
//vo层
package org.mo.vo;
public class User implements java.io.Serializable {
private String account;
private String password;

}

return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRepassword() {
return repassword;
}
public void setRepassword(String repassword) {
this.repassword = repassword;
}
public String getSumbitTag() {
return sumbitTag;
}
public void setSumbitTag(String sumbitTag) {
this.sumbitTag = sumbitTag;
}
}
