SSH-----简单后台

今天是用SSH实现一个简单的后台

那么关于SSH的配置在这里就不做赘述了，详情见:

一、登录注册

biz:

package com.psy.biz;

import java.util.List;

import com.psy.entity.User;

public interface UserBiz {
    public String addUser(User user) ;
    public User queryLogin(User user) ;
    public List<User> list();

}

impl:

package com.psy.biz.impl;

import java.util.List;

import com.psy.biz.UserBiz;
import com.psy.dao.UserDao;
import com.psy.entity.User;

public class UserBizimol implements UserBiz {
    
    private UserDao ud = new UserDao();


    public UserDao getUd() {
        return ud;
    }

    public void setUd(UserDao ud) {
        this.ud = ud;
    }

    @Override
    public String addUser(User user) {
        return ud.add(user);
    }

    @Override
    public User queryLogin(User user) {
        return ud.queryLogin(user);
    }

    @Override
    public List<User> list() {
        return ud.list();
    }

}

userdao:

package com.psy.user.dao;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.query.Query;
import org.springframework.orm.hibernate5.HibernateCallback;

import com.psy.base.dao.BaseDao;
import com.psy.book.entity.Book;
import com.psy.user.entity.User;

public class UserDao extends BaseDao {
    
    /**
     * 注册
     * @param user
     * @return
     */
    public String addUser(User user) {
        return (String) this.getHibernateTemplate().save(user);
    }
    
    /**
     * 登录
     */
    public User queryLogin(User user) {
        return  this.getHibernateTemplate().execute(new HibernateCallback<User>() {

            @Override
            public User doInHibernate(Session session) throws HibernateException {
                String hql="from User where uname='"+user.getUname()+"' and pwd='"+user.getPwd()+"'";
                 List<User> list = session.createQuery(hql).list();
                 if(list.size()==0) {
                     return null;
                 }
                return list.get(0);
            }
        });
    }
    
    
    public List<User> list(){
        return (List<User>) this.getHibernateTemplate().execute(new HibernateCallback<List<User>>() {

            @Override
            public List<User> doInHibernate(Session session) throws HibernateException {
                return session.createQuery("from User").list();
            }
        });
    }
}

user:

package com.psy.user.entity;

import com.psy.base.entity.BaseEntity;

public class User extends BaseEntity {

    private static final long serialVersionUID = 7920395488381294293L;
    
    private String uname;
    private String pwd;
    public String getUname() {
        return uname;
    }
    public void setUname(String uname) {
        this.uname = uname;
    }
    public String getPwd() {
        return pwd;
    }
    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
    
    public User() {
        super();
    }
    public User(String uname, String pwd) {
        super();
        this.uname = uname;
        this.pwd = pwd;
    }
    @Override
    public String toString() {
        return "User [uname=" + uname + ", pwd=" + pwd + "]";
    }
}

user.hbm.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class table="t_user" name="com.psy.user.entity.User">

        </id>
        
        <property name="pwd" type="java.lang.String" column="pwd"></property>
    </class>
</hibernate-mapping>

userAction:

package com.psy.user.web;

import com.opensymphony.xwork2.ModelDriven;
import com.psy.base.web.BaseAction;
import com.psy.user.biz.UserBiz;
import com.psy.user.entity.User;

public class UserAction extends BaseAction implements ModelDriven<User>{
    
    private UserBiz userBiz;
    private User user=new User();
    
    public UserBiz getUserBiz() {
        return userBiz;
    }

    public void setUserBiz(UserBiz userBiz) {
        this.userBiz = userBiz;
    }
    
    /**
     * 登录
     * @return
     */
    public String login() {
        User u = userBiz.queryLogin(user);
        System.out.println(u);
        if(u ==null) {
            
        }
        return null;
    }
    
    /**
     * 注册
     * @return
     */
    public String register() {
        String n = userBiz.addUser(user);
        System.out.println(n);
        return null;
    }

    @Override
    public User getModel() {
        return user;
    }
}

二、TreeNode

TreeNode:

package com.psy.node.entity;

import java.util.HashSet;
import java.util.Set;

public class TreeNode {
    private Integer nodeId;
    private String nodeName;
    private Integer treeNodeType;
    private Integer position;
    private String url;
    private TreeNode parent;
    private Set<TreeNode> children = new HashSet<TreeNode>();
    private Integer initChildren = 0;

    public Integer getNodeId() {
        return nodeId;
    }

    public void setNodeId(Integer nodeId) {
        this.nodeId = nodeId;
    }

    public String getNodeName() {
        return nodeName;
    }

    public void setNodeName(String nodeName) {
        this.nodeName = nodeName;
    }

    public Integer getTreeNodeType() {
        return treeNodeType;
    }

    public void setTreeNodeType(Integer treeNodeType) {
        this.treeNodeType = treeNodeType;
    }

    public Integer getPosition() {
        return position;
    }

    public void setPosition(Integer position) {
        this.position = position;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public TreeNode getParent() {
        return parent;
    }

    public void setParent(TreeNode parent) {
        this.parent = parent;
    }

    public Set<TreeNode> getChildren() {
        return children;
    }

    public void setChildren(Set<TreeNode> children) {
        this.children = children;
    }

    public Integer getInitChildren() {
        return initChildren;
    }

    public void setInitChildren(Integer initChildren) {
        this.initChildren = initChildren;
    }
}

    public List<TreeNode> list(){
        return (List<TreeNode>) this.getHibernateTemplate().execute(new HibernateCallback<List<TreeNode>>() {

            @Override
            public List<TreeNode> doInHibernate(Session session) throws HibernateException {
                // TODO Auto-generated method stub
                    return session.createQuery("from TreeNode").list();
            }
        });
