在webwork中通过validation校验框架可以轻松完成相关的表单校验，下面是相关的应用：
一、login.jsp
＜ww:form method="post"＞
＜ww:textfield label="name" name="name"/＞
＜ww:textfield label="password" name="password"/＞
＜ww:submit/＞
＜/ww:form＞
|
二、loginaction.java
1package org.register;
2
3import com.opensymphony.xwork.action;
4public class loginaction extends action {
5 string name;
6 int password;
7
8
9 public string getname() {
10 return name;
11 }
12
13 public void setname(string name) {
14 this.name = name;
15 }
16
17 public int getpassword() {
18 return password;
19 }
20
21 public void setpassword(int password) {
22 this.password = password;
23 }
24 public string execute() throws exception {
25 if(user.getname().equals("apple0668")&&user.getpassword().equals("apple0668"))
26 {
27 return success;
28 }
29 else
30 {
31 return error;
32 }
33
34 }
35
36
37}

三、填写要使用的校验器.validation.xml的格式是 ＜actionclassname＞-validation.xml
loginaction-validation.xml
1＜validators＞
2 ＜field name="name"＞
3 ＜field-validator type="requiredstring"＞
4 ＜message＞you must enter a name＜/message＞
5 ＜/field-validator＞
6 ＜/field＞
7 ＜field name="password"＞
8 ＜field-validator type="stringlength"＞
9 ＜param name="trim"＞true＜/param＞
10 ＜param name="min"＞5＜/param＞
11 ＜param name="max"＞10＜/param＞
12 ＜message＞trim-min5-max10＜/message＞
13 ＜/field-validator＞
14 ＜/field＞
15＜/validators＞
16

其他xwork.xml,web.xml webwork.properties配置省略。通过几步就可以顺利完成对表单输入校验。
还有其他校验：
1、日期校验：
1 ＜validators＞
2 ＜!-- plain validator syntax --＞
3 ＜validator type="date"＞
4 ＜param name="fieldname"＞birthday＜/param＞
5 ＜param name="min"＞01/01/1990＜/param＞
6 ＜param name="max"＞01/01/2000＜/param＞
7 ＜message＞birthday must be within ${min} and ${max}＜/message＞
8 ＜/validator＞
9
10 ＜!-- field validator syntax --＞
11 ＜field name="birthday"＞
12 ＜field-validator type="date"＞
13 ＜param name="min"＞01/01/1990＜/param＞
14 ＜param name="max"＞01/01/2000＜/param＞
15 ＜message＞birthday must be within ${min} and ${max}＜/message＞
16 ＜/field＞
17 ＜/field＞
18
19＜/validators＞
|
2、邮件格式校验：
1 ＜validators＞
2 ＜validator type="email"＞
3 ＜param name="fieldname"＞myemail＜/param＞
4 ＜message＞must provide a valid email＜/message＞
5 ＜/validator＞
6 ＜/validators＞
7
8＜!-- field validator syntax --＞
9＜field name="myemail"＞
10 ＜field-validator type="email"＞
11 ＜message＞must provide a valid email＜/message＞
12 ＜/field-validator＞
13＜/field＞
