一步一教你搭建SSH框架，实现简单的增删改查功能

一步一教你搭建SSH框架，实现简单的增删改查功能

一、首先创建一个Java web项目，并按下图建好项目目录

二、在网上搜索ssh所需jar包，并将其放到WEB_INF下的lib里面（这里截图了部分）

三、如下图配置web.xml（添加spring监听器以及struts过滤器等）

ssh

index.jsp

OpenSessionInView

org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

singleSession

true

OpenSessionInView

/*

setCharactor

org.springframework.web.filter.CharacterEncodingFilter

encoding

UTF-8

setCharactor

/*

struts2

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

struts2

*.do

*.jsp

FORWARD

REQUEST

INCLUDE

contextConfigLocation

/WEB-INF/classes/applicationContext.xml

org.springframework.web.context.ContextLoaderListener

四、在bo包建立User实体类及其Hibernate映射文件

User.java

package com.suo.bo;

/**

* User entity. @author MyEclipse Persistence Tools

*/

public class User implements java.io.Serializable {

// Fields

private Integer id;

private String name;

private String password;

private String email;

private String address;

// Property accessors

public Integer getId() {

return this.id;

}

public void setId(Integer id) {

this.id = id;

}

public String getName() {

return this.name;

}

public void setName(String name) {

this.name = name;

}

public String getPassword() {

return this.password;

}

public void setPassword(String password) {

this.password = password;

}

public String getEmail() {

return this.email;

}

public void setEmail(String email) {

this.email = email;

}

public String getAddress() {

return this.address;

}

public void setAddress(String address) {

this.address = address;

}

}

User类的Hibernate映射文件User.hbm.xml

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

Mapping file autogenerated by MyEclipse Persistence Tools

-->

五、Dao层编写  （该层用于数据的持久化操作）

UserDAO.java

package com.suo.dao;

import com.suo.bo.User;

public interface UserDAO {

/**

* 保存

* @param user

*/

void saveUser(User user);

/**

* 更新

* @param user

*/

void updateUser(User user);

/**

* 删除

*/

void deleteUser(User user);

/**

* 查询

* @return

*/

User queryUserbyName(String name);

}

UserDAO.Java

package com.suo.dao.impl;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.suo.bo.User;

import com.suo.dao.UserDAO;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {

@Override

public void saveUser(User user) {

// TODO Auto-generated method stub

getHibernateTemplate().save(user);

}

@Override

public void updateUser(User user) {

// TODO Auto-generated method stub

getHibernateTemplate().update(user);

}

@Override

public void deleteUser(User user) {

// TODO Auto-generated method stub

getHibernateTemplate().delete(user);

}

@Override

public User queryUserbyName(String name) {

// TODO Auto-generated method stub

String queryString="from User t where t.name=?";

// return (User)getHibernateTemplate().find(queryString,new String[]{name}).get(0);

return (User) getHibernateTemplate().find(queryString, name).get(0);

}

}

六、Service层编写（该层用于数据的业务处理）

UserService.java

package com.suo.service;

import com.suo.bo.User;

public interface UserService {

void save(User user);

User queryUserbyName(String name);

void updateUser(User user);

void deleteUser(String name);

}

UserServiceImpl.java

package com.suo.service.impl;

import com.suo.bo.User;

import com.suo.dao.UserDAO;

import com.suo.service.UserService;

public class UserServiceImpl implements UserService{

private UserDAO userDAO;

@Override

public void save(User user) {

// TODO Auto-generated method stub

userDAO.saveUser(user);

}

@Override

public User queryUserbyName(String name) {

// TODO Auto-generated method stub

return userDAO.queryUserbyName(name);

}

@Override

public void updateUser(User user) {

// TODO Auto-generated method stub

User userdata=userDAO.queryUserbyName(user.getName());

userdata.setAddress(user.getAddress());

userdata.setEmail(user.getEmail());

userdata.setPassword(user.getPassword());

userDAO.updateUser(userdata);

}

@Override

public void deleteUser(String name) {

// TODO Auto-generated method stub

User user=userDAO.queryUserbyName(name);

userDAO.deleteUser(user);

}

public UserDAO getUserDAO() {

return userDAO;

}

public void setUserDAO(UserDAO userDAO) {

this.userDAO = userDAO;

}

}

七、Action编写

package com.suo.action;

import com.opensymphony.xwork2.ActionSupport;

import com.suo.bo.User;

import com.suo.service.UserService;

public class UserAction extends ActionSupport{

/**

*

*/

private static final long serialVersionUID = 1L;

private UserService userService;

private User user;

private String name;

public String save(){

userService.save(user);

return "add_success";

}

public String queryUserbyName(){

user  =userService.queryUserbyName(name);

return "query_success";

}

public String deleteUser(){

userService.deleteUser(name);

return "delete_success";

}

public String updateUser(){

String str=user.getName();

//更改前preUser

User preuUser=userService.queryUserbyName(str);

userService.updateUser(user);

//更改后user

User afteruser=userService.queryUserbyName(str);

return "update_success";

}

public UserService getUserService() {

return userService;

}

public void setUserService(UserService userService) {

this.userService = userService;

}

public User getUser() {

return user;

}

public void setUser(User user) {

this.user = user;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

}

八、在hibernate.properties中配置数据相关数据，以及在applicationContext.xml中配置Spring管理

xmlns="http://www.springframework.org/schema/beans"

xmlns:p="http://www.springframework.org/schema/p"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-2.0.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop.xsd">

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

classpath:hibernate.properties

class="org.springframework.jdbc.datasource.DriverManagerDataSource">

${mysql.database.driver_class}

${mysql.database.url}

${mysql.database.username}

${mysql.database.password}

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

org.hibernate.dialect.MySQL5Dialect

classpath:com/suo/bo

九、Struts.xml文件的编写

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd"

>

/add_success.jsp

/delete_success.jsp

/update_success.jsp

/query_success.jsp

十、前端Jsp页面的编写

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@ taglib prefix="s" uri="/struts-tags"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

My JSP 'index.jsp' starting page

-->

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

-->
