如果大家对maven比较熟悉的话，建议大家用maven搭建SSH比较理想，因为我发现直接用jar包整合SSH是一件头痛的事，尝会报一些奇怪的错误，所以我借此将我整合的经验跟大家分享一下，希望对大家有所参考作用。
在这里，我建议大家整合框架的时候，一个框架一个框架的整合，整合完一个框架就测试一个框架，这样出错容易查找。
一.首先单独整合Spring。
1.导入jar包。
2.新建一个Spring配置文件，我这里新建了beans.xml。
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"<span style="white-space:pre"></span>xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<span style="white-space:pre"></span>xmlns:aop="http://www.springframework.org/schema/aop"<span style="white-space:pre"></span>xmlns:context="http://www.springframework.org/schema/context"<span style="white-space:pre"></span>xmlns:tx="http://www.springframework.org/schema/tx"<span style="white-space:pre"></span>xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd<span style="white-space:pre"></span>http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd<span style="white-space:pre"></span>http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd<span style="white-space:pre"></span>http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"><span style="white-space:pre"></span><span style="white-space:pre"></span><!-- 自动加载构建bean --> <context:component-scan base-package="cn.zym" /> </beans>
<context:component-scan base-package="cn.zym" /> ，自动扫描cn.zym包下的组件，实现注解配置数据库访问层（@Repository）、业务层（@Service）、控制层（@Controller），还有注入功能（@Resource）。
3.测试Spring的提供的控制反转和依赖注入功能。
import org.springframework.stereotype.Repository;@Repositorypublic class MyDao {<span style="white-space:pre"></span>public void prin(){<span style="white-space:pre"></span>System.out.println("我是ZYM");<span style="white-space:pre"></span>}} @Repository ，将数据库访问层的bean交给Spring生成和管理。import javax.annotation.Resource;import org.springframework.stereotype.Service;import cn.zym.dao.impl.MyDao;@Servicepublic class MyServiceImpl {<span style="white-space:pre"></span>@Resource<span style="white-space:pre"></span>private MyDao myDao;<span style="white-space:pre"></span>public void setMyDao(MyDao myDao) {<span style="white-space:pre"></span>this.myDao = myDao;<span style="white-space:pre"></span>}<span style="white-space:pre"></span><span style="white-space:pre"></span>public void print(){<span style="white-space:pre"></span>myDao.prin();<span style="white-space:pre"></span>}} @Service ，将业务层的bean交给Spring生成和管理，@Resource 将myDao注入到myServiceImpl组件中。import org.junit.BeforeClass;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.zym.service.impl.MyServiceImpl;public class MyServiceTest {<span style="white-space:pre"></span>private static ApplicationContext act;<span style="white-space:pre"></span>private static MyServiceImpl myService;<span style="white-space:pre"></span>@BeforeClass<span style="white-space:pre"></span>public static void setUpBeforeClass() throws Exception {<span style="white-space:pre"></span>act = new ClassPathXmlApplicationContext("beans.xml");<span style="white-space:pre"></span>myService = act.getBean(MyServiceImpl.class);<span style="white-space:pre"></span>}<span style="white-space:pre"></span><span style="white-space:pre"></span>@Test<span style="white-space:pre"></span>public void printTest(){<span style="white-space:pre"></span>myService.print();<span style="white-space:pre"></span>}<span style="white-space:pre"></span>} 测试Spring注解整合的是否成功，控制台如果打印出了"我是ZYM"，ok，下一步，整合hibernate。二.整合Hibernate之数据库连接。
1.导入jar包。
2.新建一个db.properties
jdbc.user=rootjdbc.password=rootjdbc.driverClass=com.mysql.jdbc.Driverjdbc.jdbcUrl=jdbc:mysql://localhost:3306/testjdbc.initPoolSize=5jdbc.maxPoolSize=10
3.在beans.xml添加，数据源连接配置
<span style="white-space:pre"></span><!-- 加载数据库属性配置文件 --><context:property-placeholder location="classpath:db.properties"/><!-- 配置 C3P0 数据源 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="user" value="${jdbc.user}"></property><property name="password" value="${jdbc.password}"></property><property name="driverClass" value="${jdbc.driverClass}"></property><property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property><property name="initialPoolSize" value="${jdbc.initPoolSize}"></property><property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property></bean> 4.测试数据库是否连接成功。import java.sql.SQLException;import javax.sql.DataSource;import org.junit.BeforeClass;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class MyDataSourceTest {private static ApplicationContext act;@BeforeClasspublic static void setUpBeforeClass() throws Exception {act = new ClassPathXmlApplicationContext("beans.xml");}//测试数据库连接成功与否@Testpublic void testDataSource() throws SQLException{DataSource ds = (DataSource) act.getBean("dataSource");System.out.println(ds.getConnection());}}如果System.out.println(ds.getConnection());能够在控制台打印出一个Connection对象，就代表连接成功。我的：com.mchange.v2.c3p0.impl.NewProxyConnection@5abf3952三.整合Hibernate之session工厂和事务管理（transactionManager）。
1.在beans.xml中添加session单例配置和事务管理。
<!-- 配置 SessionFactory --><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><!-- 配置Hibernate相关属性 --><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop></props></property><!-- 自动扫描注解方式配置实体bean --><property name="packagesToScan" value="cn.zym.model"/></bean><!-- 配置事务管理 --><bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 定义事务传播属性 --> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="new*" propagation="REQUIRED" /> <tx:method name="set*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="change*" propagation="REQUIRED" /> <tx:method name="get*" propagation="REQUIRED" read-only="true" /> <tx:method name="find*" propagation="REQUIRED" read-only="true" /> <tx:method name="load*" propagation="REQUIRED" read-only="true" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="serviceOperation" expression="execution(* cn.zym.service..*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" /> </aop:config>Spring提供管理事务的方式有两种，一种是通过注解方式实现的，一种是xml配置实现，我这边就采用了常用的xml配置，但是黎活明老师倡导使用注解方式，因为注解方式配置会更加的细致。
<aop:pointcut id="serviceOperation" expression="execution(* cn.zym.service..*.*(..))" /> 这段代码就是实现了拦截cn.zym.service包极其子包下的所有事物和方法。
2.注解创建实体bean。
import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import org.hibernate.annotations.GenericGenerator;@Entitypublic class User {private Integer id;private String username;private String password;@Id@GenericGenerator(name = "generator", strategy = "increment") @GeneratedValue(generator = "generator") @Column(length=11)public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}@Column(name="username",length=20)public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}@Column(name="password",length=20)public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}} 3.实现dao层的bean，摘抄自网上。import java.io.Serializable;import java.util.List;public interface BaseDAO<T> {/** * 保存一个对象 * * @param o * @return */ public Serializable save(T o); /** * 删除一个对象 * * @param o */ public void delete(T o); /** * 更新一个对象 * * @param o */ public void update(T o); /** * 保存或更新对象 * * @param o */ public void saveOrUpdate(T o); /** * 查询 * * @param hql * @return */ public List<T> find(String hql); /** * 查询集合 * * @param hql * @param param * @return */ public List<T> find(String hql, Object[] param); /** * 查询集合 * * @param hql * @param param * @return */ public List<T> find(String hql, List<Object> param); /** * 查询集合(带分页) * * @param hql * @param param * @param page * 查询第几页 * @param rows * 每页显示几条记录 * @return */ public List<T> find(String hql, Object[] param, Integer page, Integer rows); /** * 查询集合(带分页) * * @param hql * @param param * @param page * @param rows * @return */ public List<T> find(String hql, List<Object> param, Integer page, Integer rows); /** * 获得一个对象 * * @param c * 对象类型 * @param id * @return Object */ public T get(Class<T> c, Serializable id); /** * 获得一个对象 * * @param hql * @param param * @return Object */ public T get(String hql, Object[] param); /** * 获得一个对象 * * @param hql * @param param * @return */ public T get(String hql, List<Object> param); /** * select count(*) from 类 * * @param hql * @return */ public Long count(String hql); /** * select count(*) from 类 * * @param hql * @param param * @return */ public Long count(String hql, Object[] param); /** * select count(*) from 类 * * @param hql * @param param * @return */ public Long count(String hql, List<Object> param); /** * 执行HQL语句 * * @param hql * @return 响应数目 */ public Integer executeHql(String hql); /** * 执行HQL语句 * * @param hql * @param param * @return 响应数目 */ public Integer executeHql(String hql, Object[] param); /** * 执行HQL语句 * * @param hql * @param param * @return */ public Integer executeHql(String hql, List<Object> param); }</pre><pre name="code" class="html">import java.io.Serializable;import java.util.List;import javax.annotation.Resource;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import org.springframework.transaction.annotation.Transactional;import cn.zym.dao.BaseDAO;@Repository @SuppressWarnings("all")public class BaseDAOImpl<T> implements BaseDAO<T> {private SessionFactory sessionFactory;

} if (rows == null || rows < 1) { rows = 10; } Query q = this.getCurrentSession().createQuery(hql); if (param != null && param.length > 0) { for (int i = 0; i < param.length; i++) { q.setParameter(i, param[i]); } } return q.setFirstResult((page - 1) * rows).setMaxResults(rows).list(); } public List<T> find(String hql, List<Object> param, Integer page, Integer rows) { if (page == null || page < 1) { page = 1;

i < param.size(); i++) { q.setParameter(i, param.get(i)); } } return q.executeUpdate(); } }4.实现service层的bean。import cn.zym.model.User;public interface UserService {public abstract User findUserByUserNameAndPassword(String username,String password);public void addUser(User user);}import javax.annotation.Resource;import org.springframework.stereotype.Service;import cn.zym.dao.BaseDAO;import cn.zym.model.User;import cn.zym.service.UserService;@Service("userService")public class UserServiceImpl implements UserService {@Resource private BaseDAO<User> baseDAO;@Overridepublic void addUser(User user){baseDAO.save(user);}@Overridepublic User findUserByUserNameAndPassword(String username,String password){return baseDAO.get("from User u where u.username=? and u.password=?

1.添加jar。
2.添加web.xml配置文件。
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><!-- 服务器启动，初始化spring容器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:beans.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 数据提交中文乱码问题 --><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 延迟加载带来的问题 --><filter><filter-name>openSessionInViewFilter</filter-name><filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class><init-param><param-name>singleSession</param-name><param-value>true</param-value></init-param></filter> <!-- 添加对struts2的支持 --><filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping></web-app>3.添加struts2的配置文件（struts.xml）和添加jsp页面。
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 指定Web应用的默认编码集,相当于调用HttpServletRequest的setCharacterEncoding方法 --> <constant name="struts.i18n.encoding" value="UTF-8"/> <!-- 该属性指定需要Struts 2处理的请求后缀，该属性的默认值是action，即所有匹配*.action的请求都由Struts2处理。 如果用户需要指定多个请求后缀，则多个后缀之间以英文逗号（,）隔开。 --> <constant name="struts.action.extension" value="action"/> <!-- 设置浏览器是否缓存静态内容,默认值为true(生产环境下使用),开发阶段最好关闭 --> <constant name="struts.serve.static.browserCache" value="false"/> <!-- 当struts的配置文件修改后,系统是否自动重新加载该文件,默认值为false(生产环境下使用),开发阶段最好打开 --> <constant name="struts.configuration.xml.reload" value="true"/> <!-- 开发模式下使用,这样可以打印出更详细的错误信息 --> <constant name="struts.devMode" value="true" /> <!-- 默认的视图主题 --> <constant name="struts.ui.theme" value="simple" /> <!-- action类由spring创建 --> <constant name="struts.objectFactory" value="spring" /> <package name="s2sh" namespace="/user" extends="struts-default"> <action name="login" method="login" class="cn.zym.action.LoginAction"> <result name="success">/success.jsp</result> <result name="error">/login.jsp</result> </action> </package> </struts>login.jsp
