验证码：

如果验证码不正确，也是一种错误，验证码不正确的判断在action中。

写IUserDAO.java, IUserDAOImpl.java
User.java

package org.lxh.myzngt.vo;

public class User {
    /** sex property */
    private String sex;

    /** usermail property */
    private String usermail;

    /** userques property */
    private String userques;

    /** userid property */
    private String userid;

    /** realname property */
    private String realname;

    /** userans property */
    private String userans;

    /** userpwd property */
    private String userpwd;

    /** grade property */
    private int grade;

    /** integral property */
    private int integral;

    /** id property */
    private int id;

    public int getGrade() {
        return grade;
    }

    public void setGrade(int grade) {
        this.grade = grade;
    }

    public String getRealname() {
        return realname;
    }

    public void setRealname(String realname) {
        this.realname = realname;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public String getUserans() {
        return userans;
    }

    public void setUserans(String userans) {
        this.userans = userans;
    }

    public String getUserid() {
        return userid;
    }

    public void setUserid(String userid) {
        this.userid = userid;
    }

    public String getUsermail() {
        return usermail;
    }

    public void setUsermail(String usermail) {
        this.usermail = usermail;
    }

    public String getUserpwd() {
        return userpwd;
    }

    public void setUserpwd(String userpwd) {
        this.userpwd = userpwd;
    }

    public String getUserques() {
        return userques;
    }

    public void setUserques(String userques) {
        this.userques = userques;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public int getIntegral() {
        return integral;
    }

    public void setIntegral(int integral) {
        this.integral = integral;
    }
}

package org.lxh.myzngt.dao;

import org.lxh.myzngt.vo.User;

public interface IUserDAO {
// 用户注册
public void register(User user) throws Exception;
}

package org.lxh.myzngt.dao.impl;

import org.lxh.myzngt.dao.IUserDAO;
import org.lxh.myzngt.vo.User;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class IUserDAOImpl extends HibernateDaoSupport implements IUserDAO {

    public void register(User user) throws Exception {
        super.getSession().save(user);
    }
}

生成User.hbm.xml

注意把catalog="mldn"去掉

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

Abstract如果设置为true，表示该bean的定义是abstract的，spring将不会实例化该bean

        abstract="true">

            parent="iuserdao">

把index.jsp移到jsp文件夹中，在外面建一个index.htm
