一、创建Web项目，引入jar包
①、Struts2的jar包
②、Hibernate的jar包
注意：Struts2和Hibernate都引入了一个相同的jar包（javassist包）。删除一个
③、Spring的jar包
二、引入配置文件
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

日志配置文件
三、创建包结构
四、创建相关类
五、编写Url
<TD class=menuSmall><A class=style2 href="${ pageContext.request.contextPath }/jsp/customer/add.jsp" target=main>－ 新增客户</A></TD>
六、编写新增页面
<FORM id=form1 name=form1 action="${pageContext.request.contextPath }/customer_save.action" method=post> <TABLE cellSpacing=0 cellPadding=5 border=0> <TR> <td>客户名称：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_name"> </td> <td>客户级别 ：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_level"> </td> </TR> <TR> <td>信息来源 ：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_source"> </td> <td>所属行业 ：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_industry"> </td> </TR> <TR> <td>固定电话 ：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_phone"> </td> <td>移动电话 ：</td> <td> <INPUT class=textbox id=sChannel2 style="WIDTH: 180px" maxLength=50 name="cust_mobile"> </td> </TR> <tr> <td rowspan=2> <INPUT class=button id=sButton2 type=submit value=" 保存 " name=sButton2> </td> </tr> </TABLE> </FORM>
七、疏通基盘
①、编写Action
public class CustomerAction extends ActionSupport implements ModelDriven<Customer> { private Customer customer=new Customer(); @Override public Customer getModel() { return customer; } public void save() { System.out.println("Action中save方法执行了"); } }
②、配置struts.xml
<package name="bean" extends="struts-default" namespace="/"> <action name="customer_*" class="com.xxx.ssh.web.action.CustomerAction" method="{1}"></action> </package>
八、在Action访问Service
①、传统方式
WebApplicationContext webApplicationContext = WebApplicationContextUtils.getWebApplicationContext(ServletActionContext.getServletContext());
Object bean = webApplicationContext.getBean("CustomerServiceImpl");
②、Spring整合Struts2方式一：Action由Struts2管理
Ⅰ、引入struts-spring-plugin.jar
Ⅱ、在struts.xml中设置常量struts.objectFactory
<constant name="struts.objectFactory" value="spring"/>
开启此常量会使得struts.objectFactory.spring.autowire=name常量有效，此常量（struts.objectFactory.spring.autowire）主要将Service按照名称（是指applicationContext.xml中bean标签中id）自动注入到Action中
Ⅲ、配置applicationContext.xml，将CustomerServiceImpl交给Spring管理
<bean id="customerService" class="com.xxx.ssh.service.impl.CustomerServiceImpl"></bean>
Ⅳ、编写Action
public class CustomerAction extends ActionSupport implements ModelDriven<Customer> { private Customer customer=new Customer(); @Override public Customer getModel() { return customer; } // 属性注入 private CustomerService customerService; public void setCustomerService(CustomerService customerService) { this.customerService = customerService; } public String save() { System.out.println("Action中save方法执行了"); customerService.save(customer); return NONE; } }
③、Spring整合Struts2方式一：Action由Spring管理
Ⅰ、引入struts-spring-plugin.jar
Ⅱ、将Action交给Spring管理，并注入Service
<bean id="customerAction" class="com.xxx.ssh.web.action.CustomerAction" scope="prototype"> <property name="customerService" ref="customerService"></property> </bean>
注意：配置Action为多例（scope="prototype"）
Ⅲ、配置struts.xml的Action，action标签中class=“”的值为上面Spring的bean标签中的id的值
<package name="bean" extends="struts-default" namespace="/"> <action name="customer_*" class="customerAction" method="{1}"></action> </package>
九、Service访问Dao
①、将Dao交给Spring管理
<bean id="customerDao" class="com.xxx.ssh.dao.impl.CustomerDaoImpl" scope="prototype"> </bean>
②、Dao注入到Service中
<bean id="customerService" class="com.xxx.ssh.service.impl.CustomerServiceImpl"> <property name="customerDao" ref="customerDao"></property> </bean>
public class CustomerServiceImpl implements CustomerService { //属性注入 private CustomerDao customerDao; public void setCustomerDao(CustomerDao customerDao) { this.customerDao = customerDao; } @Override public void save(Customer customer) { System.out.println("CustomerServiceImpl的save方法执行了"); customerDao.save(customer); } }
十、Dao方法Hibernate
①、创建持久化类
Ⅰ、创建类
public class Customer { private Long cust_id; private String cust_name; private String cust_source; private String cust_industry; private String cust_level; private String cust_phone; private String cust_mobile; }
Ⅱ、映射文件
<hibernate-mapping> <!-- 建立类与表的映射 batch-size:Hibernate抓取策略 --> <class name="com.xxx.ssh.domain.Customer" table="cst_customer" batch-size="6"> <!-- 建立类中的属性与表中的主键对应 --> <id name="cust_id" column="cust_id"> <generator class="native"></generator> </id> <!-- 建立类中的普通属性与表中的字段对应 --> <property name="cust_name" column="cust_name"></property> <property name="cust_source" column="cust_source"></property> <property name="cust_industry" column="cust_industry"></property> <property name="cust_level" column="cust_level"></property> <property name="cust_phone" column="cust_phone"></property> <property name="cust_mobile" column="cust_mobile"></property> </class> </hibernate-mapping>
Ⅲ、hibernate.cfg.xml添加映射
<mapping resource="com/xxx/ssh/domain/Customer.hbm.xml"/>
②、Spring整合Hibernate（需要引入spring-orm-5.2.9.RELEASE.jar）
Ⅰ、在Spring的配置文件中，加载Hibernate的配置文件
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 加载hibernate配置文件 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"/> </bean>
Ⅱ、DAO继承HibernateDaoSupport，Spring提供了一个Hibernate的模板类简化Hibernate开发
1、HibernateDaoSupport中由sessionfactory属性，可用于属性注入，并且在设置sessionFactory时，会创建Hibernate的模板类（hibernateTemplate）
public final void setSessionFactory(SessionFactory sessionFactory) { if (this.hibernateTemplate == null || sessionFactory != this.hibernateTemplate.getSessionFactory()) { this.hibernateTemplate = createHibernateTemplate(sessionFactory); } }
2、编写Dao
public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao { @Override public void save(Customer customer) { System.out.println("CustomerDaoImpl的save方法执行了"); this.getHibernateTemplate().save(customer); } }
3、在Dao中注入sessionfactory
<bean id="customerDao" class="com.xxx.ssh.dao.impl.CustomerDaoImpl" scope="prototype"> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
测试抛出异常：Turn your Session into FlushMode.COMMIT/AUTO or remove ‘readOnly‘ marker from transaction definition.
3.1、解决方案：配置Spring的事务管理
3.1.1、配置事务管理器
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean>
3.1.2、开启事务注解
<tx:annotation-driven transaction-manager="transactionManager"/>
3.1.3、在Service上使用事务注解
@Transactional public class CustomerServiceImpl implements CustomerService {
