本文详细阐述了用户注册Action的实现方式，包括用户对象、密码重复验证、验证码验证等关键步骤，并通过验证配置文件和资源文件展示了具体的验证规则。

用实例说话吧

用户注册Action:

public class RegisterAction extends ActionSupport{
/**
* 用户对象用

*/
private User user;
/**
* 密码重复
*/
private String confirmPassword;
/**
* 验证码
*/
private String vcode;

public String execute(){

//执行业务
userService.save(user);
return Action.SUCCESS;
}

//Field accessories----------------------------------------------------------------

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}

public String getConfirmPassword() {
return confirmPassword;
}

public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}

public String getVcode() {
return vcode;
}

public void setVcode(String vcode) {
this.vcode = vcode;
}

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService = userService;
}

}

验证配置文件 RegisterAction-validation.xml

资源文件RegisterAction.properties

#用户名
user.username.empty=请输入用户名
#密码
user.password.empty=密码不能为空
user.confirmPassword.empty=密码确认不能为空
user.confirmPassword.nomatch=密码输入不一致
#出生年月
user.birthday.empty=请输入出生年月
#职业
user.job.empty=请输入职业
#手机号
user.mobile.empty=请输入手机号
user.mobile.length=手机号无效
#邮箱
user.email.empty=请输入邮箱地址
user.email.invalid=邮箱地址无效
#验证码
user.vcode.empty=请输入验证码
user.vcode.error=验证码错误

因为用到我自定义的验证，需要注册自定义的验证validator/FieldValidator,src目录下新建validator.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC

</validators>
验证和序部份

public class RegisterPasswordMatchValidator extends FieldValidatorSupport{
private String password;
private String confirmPassword;

@Override
public void validate(Object object) throws ValidationException {
  Object pvalue=this.getFieldValue(password, object);
  Object cvalue=this.getFieldValue(confirmPassword, object);
  if(!pvalue.equals(cvalue)){
   this.addFieldError(this.getFieldName(), object);
  }
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getConfirmPassword() {
return confirmPassword;
}

public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}

}

public class VerificationCodeErrorValidator extends FieldValidatorSupport{

@Override
public void validate(Object object) throws ValidationException {
  HttpSession session=ServletActionContext.getRequest().getSession();
  Object obj=session.getAttribute(Constant.VERIFICATION_CODE_SESSION);

        String fieldName = getFieldName();
        Object value = this.getFieldValue(fieldName, object);

  if(!obj.equals(value)){
            addFieldError(fieldName, object);
        }
}
}
