服务端校验可分为两种:1)编码校验 2)配置文件校验
楼上写的是配置文件的校验,我就写个编码校验吧 自己看看喜欢哪个就用哪个吧
UserAction继承了ActionSupport类,只要重写validate()方法便可实现编码校验
public void validate(){
if(null == username || "".equals(username)){
this.addFieldError("username","用户名不能为空 !");
return;
}else if(username.length() < 6 || username.length() > 12){
this.addFieldError("username","用户名长度必须为6-12位 !");
return;
}
if(null == password || "".equals(password )){
this.addFieldError("password ","密码不能为空!");
return;
}else if(password .length() < 6 || password .length() > 12){
this.addFieldError("password ","密码长度必须为6-12位!");
return;
}
}

给你 一个user的,其它自己写。只处理了非空
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "">
<validators>
<field name="name">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>用户名不能为空!</message>
</field-validator>
</field>
<field name="age">
<field-validator type="requiredstring">
<message>年龄不能为空!</message>
</field-validator>
</field>
</validators>
注意需要在和action同一个包下。
注意该XML的命名需要是UserAction-validation.xml
