整合S2SH
一、导入jar包
Spring jar包
Hibernate jar包
Struts2 jar包
以上就是整合需要的所有jar包,当然其中有重复的包,(对比之后去掉版本低的就可以了,还有就是在整合Spring4和hibernate时我们配置的hibernate最多只能配置到hibernate4[现在多数都用的是hibernate5,所以通常都会报一个错误:org/hibernate/engine/transaction/spi/TransactionContext:碰上这个错误的话不要慌张,下载hibernate4.0版本的hibernate-core-4.3.8.Finarror替换掉对应的的高版本,问题就解决了。])。
最后别忘了最重要常用的工具类包:数据驱动包是绝对不能忘记的!
二、配置spring的XML文件
1.配置数据源
建立db.properties的资源文件,配置数据源的连接信息。
在Spring配置文件中导入db.properties<context:property-placehoder/>
配置实体化c3p0的数据源ComboPooledDataSource(测试数据源配置成功)
<!-- 读取配置文件 -->
<context:property-placeholder location="classpath:db_hrm.properties" />
<!-- 定义数据源,c3p0连接池 -->
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
<property name="driverClass" value="${driverClass}"></property>
<property name="jdbcUrl" value="${jdbcUrl}"></property>
<property name="user" value="${user}"></property>
<property name="password" value="${password}"></property> <property name="minPoolSize" value="${minPoolSize}"></property>
<property name="maxPoolSize" value="${maxPoolSize}"></property>
<property name="initialPoolSize" value="${initialPoolSize}"></property>
</bean>
2.配置Hibernate的SessionFactory——通过Spring提供的LocalSessionFactoryBean来配置
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!--配置数据源属性-->
<property name="dataSource" ref="dataSource"></property>
<!--配置Hibernate配置文件的位置-->
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<!--配置Hibernate映射文件的位置,可以使用通配符-->
<property name="mappingLocation" value="classpath:com/itnba/entities/*.hbm.xml"></property>
</bean>
<!-- sessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<!-- 引入数据源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- 读取hibernate.cfg.xml文件 -->
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<!-- 自动扫描——注解方式——配置的hibernate类文件 -->
<!-- <property name="packagesToScan">
<list>
<value>com.maya.model</value>
</list>
</property> -->
<!-- 加载实体类的映射文件位置及名称 -->
<property name="mappingLocations" value="classpath:com/maya/model/*.hbm.xml"></property>
</bean>
3.配置Spring的声明式事务
配置事务管理器 -- HibernateTransactionManager
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
配置事务属性 -- 导入tx命名空间
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true" />
<tx:method name="*" />
</tx:attributes>
</tx:advice>
配置事务切点,并把切点和事务属性关联起来。--导入aop命名空间
<aop:config>
<aop:pointcut expression="execution(* com.itnba.service.*.*(..))" id="pointCut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
</aop:config>
<!-- 配置Spring声明式事务 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <!-- 配置事物通知属性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<!-- 配置事务通知属性 -->
<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>
<!-- 配置事务切面 -->
<aop:config>
<aop:pointcut expression="execution(* com.maya.service..*.*(..))" id="pointCut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
</aop:config>
以上就配置完成了:(下面是完整的)

以上示例就把hibernate整合完了,下面整合struts2:(整合struts实际上就是让spring来管理其控制层,所以实例化action类是必须的:[在上面的bean中已经通过自动扫描了],之前加载Spring的IoC容器是用代码ApplicationContext context = new ClasspathXml......("beans.xml");加载的。在Web中加载需要放在应用程序启动的时候加载,这可以使用监听器来实现。)

***********************************************************************************
以下是通过Spring的注解来注入和管理类
Dao类
@Repository("baseDao")//(实现dao访问)(自动扫描生成bean)
@SuppressWarnings("all")
public class BaseDaOImpl<T> implements BaseDao<T> { @Autowired
private SessionFactory sessionFactory; public SessionFactory getSessionFactory() {
return sessionFactory;
} public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
} private Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
Service层
@Service("menuService")
public class MenuServiceImp implements MenuService { @Resource
private BaseDao<SysMenu> baseDao; @Override
public void saveOrUpdate(SysMenu sysMenu) {
baseDao.saveOrUpdate(sysMenu);
}
Entity实体层
@Component//@Component 是一个泛化的概念,仅仅表示一个组件 (Bean) ,可以作用在任何层次。
public class SysMenu implements java.io.Serializable { private Integer id;
private String authDescription;
private String authName;
private String authPath;
private Date gmtCreate;
private Date gmtModified;
private String iconCls;
private Integer parentId;
private String state;
private Set<SysRoleidMenuid> sysRoleidMenuids = new HashSet<SysRoleidMenuid>(); public SysMenu() {
}
控制层
@Controller//@Constroller 通常作用在控制层,但是目前该功能与 @Component 相同。
public class PowerAction extends ActionSupport {
private String roleId;//获取角色id(用来判断给角色授予权限时,已经拥有的权限)
通过在类上使用 @Repository、@Component、@Service 和 @Constroller 注解,Spring 会自动创建相应的 BeanDefinition 对象,并注册到 ApplicationContext 中。这些类就成了 Spring 受管组件。
