SSH注解整合
首先需要导入依赖jar包
1 <!--spring配置--> 2 <dependency> 3 <groupId>org.springframework</groupId> 4 <artifactId>spring-context</artifactId> 5 <version>4.2.0.RELEASE</version> 6 </dependency> 7 <!--aop使用的jar--> 8 <dependency> 9 <groupId> org.aspectj</groupId > 10 <artifactId> aspectjweaver</artifactId > 11 <version> 1.8.7</version > 12 </dependency> 13 14 <!--SpringWeb--> 15 <dependency> 16 <groupId>org.springframework</groupId> 17 <artifactId>spring-web</artifactId> 18 <version>4.1.8.RELEASE</version> 19 </dependency> 20 21 <!--JavaEE--> 22 <dependency> 23 <groupId>javaee</groupId> 24 <artifactId>javaee-api</artifactId> 25 <version>5</version> 26 </dependency> 27 28 <dependency> 29 <groupId>javax.servlet</groupId> 30 <artifactId>jstl</artifactId> 31 <version>1.2</version> 32 <scope>runtime</scope> 33 </dependency> 34 35 <dependency> 36 <groupId>org.springframework</groupId> 37 <artifactId>spring-tx</artifactId> 38 <version>4.2.5.RELEASE</version> 39 </dependency> 40 41 <!--c3p0--> 42 <dependency> 43 <groupId>com.mchange</groupId> 44 <artifactId>c3p0</artifactId> 45 <version>0.9.5.2</version> 46 </dependency> 47 48 <!--hibernate jar包--> 49 <!--jta的jar包--> 50 <dependency> 51 <groupId>javax.transaction</groupId> 52 <artifactId>jta</artifactId> 53 <version>1.1</version> 54 </dependency> 55 56 <dependency> 57 <groupId>org.hibernate</groupId> 58 <artifactId>hibernate-core</artifactId> 59 <version>5.0.6.Final</version> 60 </dependency> 61 62 <!--Spring-ORM--> 63 <dependency> 64 <groupId>org.springframework</groupId> 65 <artifactId>spring-orm</artifactId> 66 <version> 4.2.2.RELEASE</version> 67 </dependency> 68 69 <!--Oracle驱动的jar--> 70 <dependency> 71 <groupId>com.oracle</groupId> 72 <artifactId>ojdbc6</artifactId> 73 <version>11.2.0.1.0</version> 74 </dependency> 75 76 <dependency> 77 <groupId>org.apache.struts</groupId> 78 <artifactId>struts2-core</artifactId> 79 <version>2.3.4.1</version> 80 </dependency> 81 82 <dependency> 83 <groupId>org.apache.struts.xwork</groupId> 84 <artifactId>xwork-core</artifactId> 85 <version>2.3.4.1</version> 86 </dependency> 87 88 <!--Struts整合Spring的jar包--> 89 <dependency> 90 <groupId>org.apache.struts</groupId> 91 <artifactId>struts2-spring-plugin</artifactId> 92 <version>2.3.4.1</version> 93 </dependency> 94 95 <!--Struts2注解支持jar包--> 96 <dependency> 97 <groupId>org.apache.struts</groupId> 98 <artifactId>struts2-convention-plugin</artifactId> 99 <version>2.3.4.1</version> 100 </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>
10
11 <!--
12 2.识别到jdbc.properties
13 -->
14 <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
15 <!--
16 3.形成SessionFactory
17 -->
18 <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
19 <property name="dataSource" ref="dataSource"></property>
20 <property name="hibernateProperties">
21 <props>
22 <!--方言-->
23 <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
24 <!--是否打印sql-->
25 <prop key="hibernate.show_sql">true</prop>
26 <prop key="hibernate.format_sql">true</prop>
27 <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop>
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
36 -->
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>
