  • SSH整合框架+mysql简单的实现

    SSH整合框架+mysql简单的实现

    1. 框架整合原理:

    struts2整合Spring 两种:

        一种struts2自己创建Action,自动装配Service ;

        一种 将Action交给Spring管理,通过Bean依赖,注入Service

        **** 引入jar包,改写Struts2 默认对象工厂, 默认StrutsObjectFactory 改为 StrutsSpringObjectFactory

        spring整合hibernate, 将sessionFactory 由Spring管理,将SessionFactory 注入HibernateTemplate , DAO通过HibernateTemplate 操作Hibernate 。

    2. 导入jar包(struts2、spring、hibernate框架需要的包及详细说明)

    通过这个过程,了解SSH框架所需要的jar包,以及它们的各自用途。下面是我引入的最小jar包的列表:
    Struts2   9个

    1.struts2-core-2.2.3.jar struts的核心jar包。
    2.freemarker-2.3.16.jar Freemarker是struts2默认的模版语言
    3.commons-logging-1.1.1.jar Apache  Commons包中的一个,包含了日志功能,必须使用的jar包
    4.ognl-3.0.1.jar Struts2默认的表达式语言OGNL:对象图形化导航语言
    5.xwork-core-2.2.3.jar Struts2核心包,毕竟struts2很大部分是来webwork6.commons-io-2.0.1.jar 封装了一些输入输出流的常用操作
    7.commons-fileupload-1.2.2.jar 用来实现文件上传
    8. struts2-json-plugin-2.2.3.jar JSON 插件提供了一个 "json" 结果类型来把 action 序列化成 JSON
    9. struts2-spring-plugin-2.1.6.jar 使struts2能集成到spring中

    Spring框架 13个

    1.org.springframework.aop.jar 包含在应用中使用Spring的AOP特性时所需的类
    2. org.springframework.beans.jar 所有应用都要用到的,它包含访问配置文件、创建和管理bean以及进行Inversion of Control / Dependency Injection(IoC/DI)操作相关的所有类。
    3.org.springframework.context.support.jar 包含支持缓存Cache(ehcache)、JCA、JMX、邮件服务(Java Mail、COS Mail)、任务计划Scheduling(Timer、Quartz)方面的类。
    4.org.springframework.context.jar 为Spring核心提供了大量扩展。可以找到使用Spring ApplicationContext特性时所需的全部类,JDNI所需的全部类,UI方面的用来与模板(Templating)引擎如 Velocity、FreeMarker、 JasperReports集成的类,以及校验Validation方面的相关类。
    5.org.springframework.core.jar 包含Spring框架基本的核心工具类,Spring其它组件要都要使用到这个包里的类,是其它组件的基本核心。
    6.org.springframework.expression.jar Spring表达式语言
    7.org.springframework.jdbc.jar 包含对Spring对JDBC数据访问进行封装的所有类。
    8.org.springframework.jms.jar 提供了对JMS 1.0.2/1.1的支持类。
    9. org.springframework.orm.jar 包含Spring对DAO特性集进行了扩展,使其支持 iBATIS、JDO、OJB、TopLink,因为Hibernate已经独立成包了,现在不包含在这个包里了。这个jar文件里大部分的类都要依赖spring-dao.jar里的类,用这个包时你需要同时包含spring-dao.jar包。
    10.org.springframework.transaction.jar 为JDBC、Hibernate、JDO、JPA等提供的一致的声明式和编程式事务管理。
    11.org.springframework.web.struts.jar Struts框架支持,可以更方便更容易的集成Struts框架。
    12.org.springframework.web.jar 包含Web应用开发时,用到Spring框架时所需的核心类,包括自动载入WebApplicationContext特性的类、Struts与JSF集成类、文件上传的支持类、Filter类和大量工具辅助类。
    13. org.springframework.asm.jar Spring独立的asm程序, Spring2.5.6的时候需要asmJar 包,3.0开始提供他自己独立的asmJar

    Hibernate3框架10个

    1.hibernate3.jar 这个是hibernate3.0的核心jar包,必须的,没的选,像我们常用的Session,Query,Transaction都位于这个jar文件中,必要。

    2.cglib-2.1.3.jar CGLIB库,Hibernate用它来实现PO字节码的动态生成,非常核心的库,必要。

    3.asm.jar      ASM字节码库 如果使用“cglib”则必要,必要

    4.asm-attrs.jar     ASM字节码库 如果使用“cglib”则必要,必要
    5.ehcache.jar      EHCache缓存 如果没有其它缓存,则必要,必要
    6.antlr.jar     语言转换工,Hibernate利用它实现 HQL 到 SQL。 ANother Tool for Language Recognition是一个工具,必要

    7.jta.jar JTA规范,当Hibernate使用JTA的时候需要,不过AppServer都会带上,所以也是多余的。但是为了测试方便建议还是带上。必要

    8.commons-collections.jar ApacheCommons包中的一个,包含了一些Apache开发的集合类,功能比java.util.*强大。必要
    9.dom4j 是一个Java的XMLAPI,类似于jdom,用来读写XML文件的。Hibernate用它来读写配置文件。必要
    10.C3P0.jar  C3P0数据库连接池提供数据库连接池

    其他4个

    1. com.springsource.javax.mail-1.4.0.jar Java email组建,提供email的常用方法
    2. mysql-connector-java-5.0.8-bin.jar mysql数据库驱动
    3. commons-lang-2.3.jar Apache Commons包中的一个,包含了一些数据类型工具类,是java.lang.*的扩展。必须使用的jar包http://commons.apache.org/lang/
    4. log4j-1.2.15.jar 提供日志功能http://logging.apache.org/log4j/

    单元测试和其他

    junit-4.10.jar

    xercesImpl-2.8.1.jar   ---这里用到Base64编码(可以不引入)

    hibernate3:http://sourceforge.net/projects/hibernate/files/hibernate3/
    spring3:http://www.springsource.org/download

    3. 创建web项目与包结构:

    clip_image002clip_image004clip_image006

     

    4. 配置SSH开发框架

    一般Java都是三层架构 数据访问层(dao) 业务逻辑层(biz 或者services) 界面层(ui) action 是业务层的一部分,是一个管理器 (总开关)(作用是取掉转)(取出前台界面的数据,调用biz方法,转发到下一个action或者页面)  模型成(model)一般是实体对象(把现实的的事物变成java中的对象)作用是一暂时存储数据方便持久化(存入数据库或者写入文件)而是 作为一个包裹封装一些数据来在不同的层以及各种java对象中使用  dao是数据访问层 就是用来访问数据库实现数据的持久化(把内存中的数据永久保存到硬盘中)

     

    Dao主要做数据库的交互工作 Modle 是模型 存放你的实体类 Service 做相应的业务逻辑处理 Action是一个控制器

    1.在web.xml中加入如下代码令服务器自动加载Spring ,Struts,Hibernate

      14:  
      15:     User find(User user);
      16:  
      17: }

    13.编写访问层实现类TestDaoImpl.java

       1: package com.SSH.dao.impl;
       2:  
       3: import java.util.List;
       4:

      20:         String username =user.getUsername();
      21:         String password = user.getPassword();
      22:         String hql = "from User u where  u.username = ? and u.password = ?";
      23:         List list = (List) this.getHibernateTemplate().find(hql, username,password);
      24:         if(list != null && list.size() > 0){

      27:         return null;
      28:     }
      29:  
      30: }

    14.编写实体类(模型)Userjava类

       1: package com.SSH.entity;
       2: // Generated 2016-9-26 17:31:58 by Hibernate Tools 5.1.0.Beta1
       3:  
       4: /**
       5:  * User generated by hbm2java
       6:  */
       7: public class User implements java.io.Serializable {
       8:  
       9:     private Integer id;
      10:     private String username;
      11:     private String password;

      13:     public User() {
      14:     }
      15:  
      16:     public User(String username, String password) {
      17:         this.username = username;
      18:         this.password = password;

      25:     public void setId(Integer id) {
      26:         this.id = id;
      27:     }
      28:  
      29:     public String getUsername() {
      30:         return this.username;
      31:     }
      32:  
      33:     public void setUsername(String username) {
      34:         this.username = username;
      35:     }
      36:  
      37:     public String getPassword() {
      38:         return this.password;
      39:     }

      42:         this.password = password;
      43:     }
      44:  
      45:     @Override
      46:     public String toString() {
      47:         return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
      48:     }
      49:  
      50: }

    15.编写映射文件User.hbm.xml

       1: xml version="1.0"?>
       2: DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
       3: "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
       4: 
       5: <hibernate-mapping>
       6:     <class name="com.SSH.entity.User" table="user">
       7:         <id name="id" type="java.lang.Integer">
       8:             <column name="id" />
       9:             <generator class="identity" />
      10:         id>
      11:         <property name="username" type="string">
      12:             <column name="username" length="20" />
      13:         property>
      14:         <property name="password" type="string">
      15:             <column name="password" length="20" />
      16:         property>
      17:     class>
      18: hibernate-mapping>

    <--    14、15 两步可以用eclipse的插件来生成对应的文件,依据对应的数据库    -->

    16.用到的对应的数据库文件 db_ssh-unite.sql

    首先创建ssh_unite数据库:

    create database ssh_unite;

    然后运行下面语句便可:

       1: /*
       2: Navicat MySQL Data Transfer
       3: 
       4: Source Server         : Mysql
       5: Source Server Version : 50549
       6: Source Host           : localhost:3306
       7: Source Database       : ssh_unite
       8: 
       9: Target Server Type    : MYSQL
      10: Target Server Version : 50549
      11: File Encoding         : 65001
      12: 
      13: Date: 2016-09-29 15:29:54
      14: */
      15:  
      16: SET FOREIGN_KEY_CHECKS=0;
      17:  
      18: -- ----------------------------
      19: -- Table structure for user
      20: -- ----------------------------
      21: DROP TABLE IF EXISTS `user`;
      22: CREATE TABLE `user` (
      23:   `id` int(11) NOT NULL AUTO_INCREMENT,
      24:   `username` varchar(20) DEFAULT NULL,
      25:   `password` varchar(20) DEFAULT NULL,
      26:   PRIMARY KEY (`id`)
      27: ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
      28:  
      29: -- ----------------------------
      30: -- Records of user
      31: -- ----------------------------
      32: INSERT INTO `user` VALUES ('1', 'aaa', 'aaa');
      33: INSERT INTO `user` VALUES ('2', 'bb', 'bbb');
      34: INSERT INTO `user` VALUES ('3', 'HRuinger', '1234');
