首先需要导入依赖jar包

  1   <!--spring配置-->
  2         <dependency>

resources层:

applicationContext.xml:

 1 <!--
 2 1.数据源  c3p0
 3 -->
 4     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
 5         <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
 6         <property name="driverClass" value="${jdbc.driverClass}"></property>
 7         <property name="user" value="${jdbc.username}"></property>
 8         <property name="password" value="${jdbc.password}"></property>
 9     </bean>

15     <!--
16  3.形成SessionFactory

18     <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

24                 <!--是否打印sql-->

28             </props>
29         </property>
30         <!--关联小配置-->
31          <property name="packagesToScan" value="entity"></property>
32     </bean>
33 
34 <!--
35 7.事务管理器

37     <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
38         <property name="sessionFactory" ref="sessionFactory"></property>
39     </bean>
40 <!--
41 8.事务真实配置
42 -->
43     <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>

jdbc.properties:

jdbc.jdbcUrl=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.driverClass=oracle.jdbc.driver.OracleDriver
jdbc.username=y2166
jdbc.password=y2166

搭建架构分层：

action：

 1 @Controller("deptAction")
 2 @ParentPackage("struts-default")
 3 @Namespace("/")
 4 @Scope("prototype") //多例的
 5 public class DeptAction implements Action {
 6     private Dept dept;
 7     @Resource(name = "deptService")  // DI  依赖注入
 8     IDeptService service;
 9     @org.apache.struts2.convention.annotation.Action(value = "/add",results={@Result(name = "success",location="/jsp/index.jsp")})
10     public String execute() throws Exception {
11         service.addDept(dept);
12         return SUCCESS;
13     }
14 
15     public Dept getDept() {
16         return dept;
17     }
18 
19     public void setDept(Dept dept) {
20         this.dept = dept;
21     }
22 
23 }

 

dao：

IDeptDAO：

DeptDAO.xml:

 1 @Repository("deptDAO")
 2 public class DeptDAOImpl implements IDeptDAO {
 3     @Resource(name = "sessionFactory")  //JDK 1.4
 4             /*@Autowired()
 5             @Qualifier("sessionFactory")*/
 6     SessionFactory sessionFactory;
 7     public int addDept(Dept dept) {
 8         Session session = sessionFactory.getCurrentSession();
 9         Serializable count = session.save(dept);
10         return (Integer)count;
11     }
12 
13     public SessionFactory getSessionFactory() {
14         return sessionFactory;
15     }
16 
17     public void setSessionFactory(SessionFactory sessionFactory) {
18         this.sessionFactory = sessionFactory;
19     }
20 }

 

service：

IDeptServcie:

DeptServiceImpl:

 1 @Service("deptService")
 2 public class DeptServiceImpl implements IDeptService {
 3     @Resource(name = "deptDAO")
 4     IDeptDAO dao;
 5     @Transactional
 6     public int addDept(Dept dept) {
 7         return dao.addDept(dept);
 8     }
 9 
10     public IDeptDAO getDao() {
11         return dao;
12     }
13 
14     public void setDao(IDeptDAO dao) {
15         this.dao = dao;
16     }
17 }

 

entity：

 1 @Entity
 2 @Table(name = "Dept")
 3 public class Dept {
 4     @Id
 5     @GeneratedValue  //native  xml中native  Oracle
 6     private Integer deptno;
 7     @Column
 8     private String deptname;
 9 
10     public Integer getDeptno() {
11         return deptno;
12     }
13 
14     public void setDeptno(Integer deptno) {
15         this.deptno = deptno;
16     }
17 
18     public String getDeptname() {
19         return deptname;
20     }
21 
22     public void setDeptname(String deptname) {
23         this.deptname = deptname;
24     }
25 }

然后配置web.xml：

 1   <!--Spring配置
 2  1.上下文  识别applicationContext.xml
 3 
 4  2.监听器 在Tomcat容器启动的时候，帮我创建Spring容器，并且放入application中-->
 5   <context-param>
 6     <param-name>contextConfigLocation</param-name>
 7     <param-value>classpath:applicationContext.xml</param-value>
 8   </context-param>
 9 
10   <!--Struts2配置  核心过滤器 -->
11   <filter>
12     <filter-name>struts</filter-name>
13     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
14   </filter>
15   <filter-mapping>
16     <filter-name>struts</filter-name>
17     <url-pattern>/*</url-pattern>
18   </filter-mapping>
19 
20   <listener>
21     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
22   </listener>
