Struts2 表单验证之HelloWorld

这个是我第一次发帖，没有经验，自己一在校学生，自己也是刚学struts2几天，这个纯粹是为了入门，所以验证类型只是随意，大家看懂了这个我想对于其他的验证类型也小菜了吧！

至于struts自带的标签，我不喜欢用，因为自带了theme，但是用el也会很麻烦，有“["这个符号。。。

恳请哪位懂得如何拿到他的plain text 的教一下，感激不尽！

package cn.longkai.validate;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {
	private static final long serialVersionUID = 1L;

	private String userName;
	private String password;

	@Override
	public String execute() throws Exception {
		return super.execute();
	}

	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;
	}
}
