Spring整合Hibernate与Struts

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)

</beans>

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。
