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)

spring3:http://www.springsource.org/download
3. 创建web项目与包结构:
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

41: return INPUT;
42: }
43: }
44:
45: }
10.编写Service层 接口ITestService.java
1: package com.SSH.service;
2:
3: import com.SSH.entity.User;
4:
5: public interface ITestService {
6:
7: User findUser(User user);
8:
9: }
11.编写Service层实现类TestServiceImpl.java
1: package com.SSH.service.impl;
2:
3: import com.SSH.dao.ITestDao;
4: import com.SSH.entity.User;
5: import com.SSH.service.ITestService;
6:
7: /**
8: * 业务实现层
9: *
10: * @author HRuinger
11: *
12: */
13:
14: public class TestServiceImpl implements ITestService {
15:
16: private ITestDao testDao;
17:
18: public void setTestDao(ITestDao testDao) {
19: this.testDao = testDao;
20: }
21:
22: @Override
23: public User findUser(User user) {
24:
25: return testDao.find(user);
26: }
27:
28: }
12.编写数据访问层(Dao层)接口 ITestDao.java类
1: package com.SSH.dao;
2:
3: import com.SSH.entity.User;
4:
5: /**
6: *
7: * @author HRuinger
8: *
9: */
10:
11:
12: public interface ITestDao {
13:
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:
5: import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
6:
7: import com.SSH.dao.ITestDao;
8: import com.SSH.entity.User;
9:
10: /**
11: *
12: * @author HRuinger
13: *
14: */
15:
16: public class TestDaoImpl extends HibernateDaoSupport implements ITestDao {
17:
18: @Override
19: public User find(User user) {
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){
25: return list.get(0);
26: }
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;
12:
13: public User() {
14: }
15:
16: public User(String username, String password) {
17: this.username = username;
18: this.password = password;
19: }
20:
21: public Integer getId() {
22: return this.id;
23: }
24:
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: }
40:
41: public void setPassword(String password) {
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>
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‘);
