SSH架构的原始配置
准备工作：新建一个纯的JavaWeb项目（命名为ssh）
（1）新建resources资源目录，新建webapp目录（webapp下新建lib目录，classes目录，以及web.xml文件）
（2）对项目ssh做buildpath，选择classes为字节码文件存放目录
（3）resources资源目录下复制db.properties文件和applicationContext.xml文件
1 #key-value 2 jdbc.driverClassName=com.mysql.jdbc.Driver 3 jdbc.url=jdbc:mysql://localhost:3306/springDemo 4 jdbc.username=root 5 jdbc.password=admin 6 jdbc.maxActive=5
第一部分：Spring与Hibernate集成：
1.导入相关jar包
（1）导入Hibernate相关的jar包：如下图所示，出去红色方框外的都为\hibernate-release-4.3.5.Final\lib\required下的所有包
（2）导入spring相关jar包：包括libs中的包和依赖包
（3）导入mysql驱动包和阿里巴巴的数据库连接池包druid包
（4）以及其他工具包如lombok（之前在eclipse中配置过的话，直接添加user librart）、juit等
2.准备实体类和映射文件（映射文件模板去搜user.hbm.xml）
3.准备DAO接口及其实现类 、测试类
1 package com.wanglei.ssh.domain;

6 @Setter@Getter
7 public class Employee {
8 private Long id;
9 private String name;
10 private Integer age;
11 private Department dept;
12 }
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC 3 "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 5 6 <!-- 7 8 --> 9 10 <hibernate-mapping package="com.wanglei.ssh.domain"> 11 <class name="Employee" table="employee"> 12 <id name="id"> 13 <generator class="native"></generator> 14 </id> 15 <property name="name"></property> 16 <property name="age"></property> 17 </class> 18 </hibernate-mapping>

8 void save(Employee e);
9 void update(Employee e);
10 void delete(Employee e);
11 Employee get(Long id);
12 List<Employee> listAll();
13
14 }
1 package com.wanglei.ssh.dao.impl;
2

5 import org.hibernate.Session;
6 import org.hibernate.SessionFactory;
7
8 import com.wanglei.ssh.dao.IEmployeeDAO;
9 import com.wanglei.ssh.domain.Employee;
10
11 public class EmployeeDAOImpl implements IEmployeeDAO {
12
13 private SessionFactory sessionFactory;
14 //注入属性：sessionFactory
15 public void setSessionFactory(SessionFactory sessionFactory){
16 this.sessionFactory = sessionFactory;
17 }
18 @Override
19 public void save(Employee e) {
20 Session session = sessionFactory.getCurrentSession();//此方法需要配置事务管理器
21 session.save(e);
22 }
23 @Override
24 public void update(Employee e) {
25 Session session = sessionFactory.getCurrentSession();//此方法需要配置事务管理器
26 session.update(e);
27 }
28 @Override
29 public void delete(Employee e) {
30 Session session = sessionFactory.getCurrentSession();//此方法需要配置事务管理器
31 session.delete(e);
32 }
33 @Override
34 public Employee get(Long id) {
35 Session session = sessionFactory.getCurrentSession();//此方法需要配置事务管理器
36 return (Employee) session.get(Employee.class, id);
37 }
38 @Override
39 public List<Employee> listAll() {
40 Session session = sessionFactory.getCurrentSession();//此方法需要配置事务管理器
41 return session.createCriteria(Employee.class).list();//没有查询条件时，用此方法更简单
42 //return session.createQuery("SELECT e FROM Employee e").list();
43 }
44 }
4.开始正式整合spring和hibernate
（1）新建applicationContext.xml文件 配置连接池（使用属性占位符）
（2）配置SessionFactory（此处的session和HttpSession完全不一样，前者是hibernate操作数据库的对象，后者是指HTTP会话中的session）
其中：a.配置dataSource属性，把连接池关联起来
b.配置hibernateProperties属性，即hibernate的属性配置，（方言，是否打印sql，格式化sql等）
c.配置映射文件的位置，mappingLocations属性
d.配置DAO
（3）编写Service接口及其实现类
1 package com.wanglei.ssh.service;
2
3 import java.util.List;
4
5 import com.wanglei.ssh.domain.Employee;
6
7 public interface IEmployeeService {
8 void save(Employee e);
9 void update(Employee e);
10 void delete(Employee e);
11 Employee get(Long id);
12 List<Employee> listAll();
13
14 }
1 package com.wanglei.ssh.service.impl;
2
3 import java.util.List;
4
5 import lombok.Setter;
6
7 import com.wanglei.ssh.dao.IEmployeeDAO;
8 import com.wanglei.ssh.domain.Employee;
9 import com.wanglei.ssh.service.IEmployeeService;
10
11 public class EmployeeServiceImpl implements IEmployeeService{
12 @Setter
13 private IEmployeeDAO employeeDAO;
14
15 @Override
16 public void save(Employee e) {
17 employeeDAO.save(e);
18 //throw new RuntimeException("故意加的，测试事务");
19 }
20
21 @Override
22 public void update(Employee e) {
23 employeeDAO.update(e);
24 }
25
26 @Override
27 public void delete(Employee e) {
28 employeeDAO.delete(e);
29 }
30
31 @Override
32 public Employee get(Long id) {
33 return employeeDAO.get(id);
34 }
35
36 @Override
37 public List<Employee> listAll() {
38 return employeeDAO.listAll();
39 }
40
41 }
（4）继续完成applicationContext.xml文件
e.配置事务管理器
f.配置Service

69
（5）编写一个测试类
1 package com.wanglei.ssh.test;
2
3 import java.util.List;
4 import java.util.Map;
5
6 import org.junit.Test;
7 import org.junit.runner.RunWith;
8 import org.springframework.beans.factory.annotation.Autowired;
9 import org.springframework.test.context.ContextConfiguration;
10 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
11
12 import com.wanglei.ssh.domain.Employee;
13 import com.wanglei.ssh.service.IEmployeeService;
14
15 @RunWith(SpringJUnit4ClassRunner.class)
16 @ContextConfiguration("classpath:applicationContext.xml")
17 public class EmployeeServiceTest {
18
19 @Autowired
20 private IEmployeeService service;
21
22 @Test
23 public void testSave() {
24 Employee emp = new Employee();
25 emp.setName("小明");
26 emp.setAge(21);
27 service.save(emp);
28 }
29
30 @Test
31 public void testUpdate() {
32 Employee emp = new Employee();
33 emp.setName("小莉");
34 emp.setAge(17);
35 emp.setId(3L);
36 service.update(emp);
37 }
38
39 @Test
40 public void testDelete() {
41 Employee emp = new Employee();
42 emp.setId(3L);
43 service.delete(emp);
44 }
45
46 @Test
47 public void testGet() {
48 Employee emp = new Employee();
49 emp.setId(1L);
50 Employee result = service.get(1L);
51 System.out.println(result);
52 }
53
54 @Test
55 public void testListAll() {
56 List<Employee> es = service.listAll();
57 for (Employee e : es) {
58 System.out.println(e);
59 }
60 }
61
62 }
第二部分：Spring与Struts2集成：
准备工作，集成Struts2：
拷贝jar包
导入\struts-2.3.24\apps\struts2-blank\WEB-INF\lib下的所有jar包
导入\struts-2.3.24\lib下名为struts2-spring-plugin-2.3.24的jar包、
导入开发web的Servlet-api.jar
并作buildpath。
注意：其中apps\struts2-blank\WEB-INF\lib下的javassist-3.11.0.GA.jar与Hibernate中的重复，所以去掉这个jar包。
2.配置前端控制器(web.xml)
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns="http://java.sun.com/xml/ns/javaee" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 5 http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 6 version="3.0"> 7 8 <!-- 配置加载文件的路径，告诉监听器去哪里找Spring的配置文件 --> 9 <context-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:applicationContext.xml</param-value> 12 </context-param> 13 14 <!-- 配置监听器，Tomcat启动，就开始启动并初始化Spring容器 --> 15 <listener> 16 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 17 </listener> 18 19 <!-- 前端控制器 --> 20 <filter> 21 <filter-name>struts2</filter-name> 22 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 23 </filter> 24 <filter-mapping> 25 <filter-name>struts2</filter-name> 26 <url-pattern>/*</url-pattern> 27 </filter-mapping> 28 </web-app>
3.编写Action和配置Action（Struts.xml文件）
1 package com.wanglei.ssh.web.action;
2
3 import lombok.Setter;
4 import com.opensymphony.xwork2.ActionContext;
5 import com.opensymphony.xwork2.ActionSupport;
6 import com.wanglei.ssh.service.IEmployeeService;
7
8 public class EmployeeAction extends ActionSupport{
9 private static final long serialVersionUID = 1L;
10
11 @Setter
12 private IEmployeeService employeeService;
13
14 public String execute() throws Exception {
15 ActionContext.getContext().put("employee",employeeService.listAll());
16 return "list";
17 }
18
19 }
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 6 <struts> 7 8 <constant name="struts.devMode" value="true" /> 9 10 <package name="default" namespace="/" extends="struts-default"> 11 <action name="employee" class="employeeAction"> 12 <result name="list">/WEB-INF/views/employee/list.jsp</result> 13 </action> 14 </package> 15 </struts>
4.在applicationContext.xml中增加配置Action（配好之后，在struts.xml文件中改为<action name="employee" class="employeeAction">）
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

59
60 <!-- 配置DAO -->

70 <property name="employeeService" ref="employeeService"></property>
71 </bean>
72 </beans>
73
5.新建list.jsp页面
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <%@ taglib prefix="s" uri="/struts-tags" %> 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 5 <html> 6 <head> 7 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 8 <title>Insert title here</title> 9 </head> 10 <body> 11 <s:debug></s:debug> 12 </body> 13 </html>
6.新建一个domain类Department.java和Department.hbm.xml
domain.Department
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC 3 "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 5 6 <!-- 7 8 --> 9 10 <hibernate-mapping package="com.wanglei.ssh.domain"> 11 <class name="Employee" table="employee"> 12 <id name="id"> 13 <generator class="native"></generator> 14 </id> 15 <property name="name"></property> 16 <property name="age"></property> 17 <many-to-one name="dept" column="dept_name"></many-to-one> 18 </class> 19 </hibernate-mapping>
7.在web.xml文件中加入如下代码（OSIV问题，目的是让session在请求的时候打开，在响应完毕后再关闭，不能在业务层内关闭。）
1 <!-- OSIV模式 --> 2 <filter> 3 <filter-name>OSIV</filter-name> 4 <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> 5 </filter> 6 <filter-mapping> 7 <filter-name>OSIV</filter-name> 8 <url-pattern>/*</url-pattern> 9 </filter-mapping>
8.运行后数据库再创建除了Department的表，在该表内赋值。
这样，调试成功，整个SSH框架就搭建起来了！
