SSH框架的增、删、查、改的实现

搭建SSH框架请参考文章（http://blog.csdn.net/qq_39189632/article/details/78401657）

1.创建User.java

package com.user.model;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;/** * 用户表 * @author LICHENGLONG * */@Entity@Table(name="tb_user")public class User {    private Integer id;    private String username;    private String password;    private Integer userid;    @Id    @GeneratedValue(strategy=GenerationType.AUTO)    @Column(name="id")    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    @Column(name="username")    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    @Column(name="password")    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    @Column(name="userid")    public Integer getUserid() {        return userid;    }    public void setUserid(Integer userid) {        this.userid = userid;    }    @Override    public String toString() {        return "User [id=" + id + ", username=" + username + ", password="                + password + ", userid=" + userid + "]";    }}

2、创建UserDao.java

package com.user.dao;import java.util.List;import javax.annotation.Resource;import org.hibernate.SessionFactory;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import org.springframework.stereotype.Repository;import com.user.model.User;@Repository(value="userDao")public class UserDao extends HibernateDaoSupport {    boolean bool = false;    @Resource(name="sessionFactory")    public void setSuperSessionFactory(SessionFactory sessionFactory){        super.setSessionFactory(sessionFactory);    }    /**     * 新增     * @param obj     * @return     */    public boolean save(Object obj){        try {            super.getHibernateTemplate().save(obj);            bool = true;        } catch (Exception e) {            bool = false;        }        return bool;    }    /**     * 修改     * @param obj     * @return     */    public boolean update(Object obj){        try {            super.getHibernateTemplate().update(obj);            bool = true;        } catch (Exception e) {            bool = false;        }        return bool;    }    /**     * 删除     * @param obj     * @return     */    public boolean delete(Object obj){        try {            super.getHibernateTemplate().delete(obj);            bool = true;        } catch (Exception e) {            bool = false;        }        return bool;    }    /**     * 查询     * @param hql     * @return     */    public List<User> find(String hql){        return super.getHibernateTemplate().find(hql);    }}

3.创建接口IUserService.java

package com.user.service;import java.util.List;import com.user.model.User;public interface IUserService {    public abstract boolean save(User user);    public abstract List<User> listUser();    public abstract List<User> listUserId(Integer id);    public abstract List<User> listUserLogin(String username,String password);    public abstract boolean update(User user);    public abstract boolean delete(User user);}

4、创建UserService.java

package com.user.service.impl;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.user.dao.UserDao;import com.user.model.User;import com.user.service.IUserService;@Servicepublic class UserService implements IUserService {    @Resource(name="userDao")    private UserDao userDao;    public boolean save(User user) {        boolean bool = userDao.save(user);        return bool;    }    public List<User> listUser() {        List<User> listUser = userDao.find("from User");        return listUser;    }    public List<User> listUserId(Integer id) {        List<User> listUser = userDao.find("from User where id="+id);        return listUser;    }    public List<User> listUserLogin(String username, String password) {        List<User> listUser = userDao.find("from User where username="+"'"+username+"'"+" and password="+"'"+password+"'");        return listUser;    }    public boolean update(User user) {        boolean bool = userDao.update(user);        return bool;    }    public boolean delete(User user) {        boolean bool = userDao.delete(user);        return bool;    }}

5、创建 UserAction.java

package com.user.action;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Component;import com.opensymphony.xwork2.ActionSupport;import com.user.model.User;import com.user.service.IUserService;@Scope("prototype")@Component(value="user.userAction")public class UserAction extends ActionSupport {    @Autowired    private IUserService userService;    private Integer id;    private String username;    private String password;    private Integer userid;    private List<User> listUser;    public String add(){        if(!username.equals("") && !password.equals("") && userid > 0){            User user = new User();            user.setUsername(username);            user.setPassword(password);            user.setUserid(userid);            boolean bool = userService.save(user);            if (bool) {                return "login";            }        }        return "add";    }    public String userlogin(){        if(!username.equals("") && !password.equals("")){            System.out.println("username:"+username+",password:"+password);            List<User> listUser = userService.listUserLogin(username, password);            System.out.println(listUser);            if(listUser.size() > 0){                return findData();            }        }        return "login";    }    public String findData(){        listUser = userService.listUser();        return "main";    }    public String findDatauserId(){        if(id > 0){            listUser = userService.listUserId(id);            return "update";        }        return findData();    }    public String update(){        if(id > 0 && !username.equals("") && !password.equals("") && userid > 0){            User user = new User();            user.setId(id);            user.setUsername(username);            user.setPassword(password);            user.setUserid(userid);            boolean bool = userService.update(user);            if (bool) {                return findData();            }        }        return "update";    }    public String delete(){        if(id > 0){            User user = new User();            user.setId(id);            boolean bool = userService.delete(user);            if (bool) {                return findData();            }        }        return findData();    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    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;    }    public Integer getUserid() {        return userid;    }    public void setUserid(Integer userid) {        this.userid = userid;    }    public List<User> getListUser() {        return listUser;    }    public void setListUser(List<User> listUser) {        this.listUser = listUser;    }}

6、创建 struts-user.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>  <package name="user" extends="struts-default" namespace="/user">    <action name="*User" class="user.userAction" method="{1}">        <result name="login">/login.jsp</result>        <result name="add">/add.jsp</result>        <result name="main">/main.jsp</result>        <result name="update">/update.jsp</result>    </action>  </package></struts>

7、创建 struts.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>  <include file="struts-user.xml"></include></struts>

以下是页面代码
