步骤二：配置Activiti

　　配置内容：1.数据源         2.配置processEngine对象        3.配置XXXXService

                        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--数据源-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/activiti"/>
        <property name="username" value="root"/>
        <property name="password" value="123"/>
    </bean>

    <!--配置ProcessEngineConfiguration-->
    <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
        <!--数据源-->
        <property name="dataSource" ref="dataSource"/>
        <!--配置事务-->
        <property name="transactionManager" ref="transactionManager"/>
        <!--数据生成策略    true   false   create   drop-create -->
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>

    <!--配置ProcessEngine-->
    <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
        <property name="processEngineConfiguration" ref="processEngineConfiguration"/>
    </bean>

    <!--配置RepositoryService-->
    <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/>
    <!--配置RuntimeService-->
    <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService"/>
    <!--配置TaskService-->
    <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService"/>
    <!--配置HistoryService-->
    <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/>

    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
</beans>

步骤三：测试Activiti

@RunWith(SpringJUnit4ClassRunner.class)     //测试方式  junit4.12+
@ContextConfiguration("classpath:activiti-spring.xml")   //配置
public class ActivitiSpringTest {
    @Resource
    private RepositoryService repositoryService;
    @Resource
    private RuntimeService runtimeService;


    /**
     * 测试流程部署
     */
    @Test
    public void deployment(){
        repositoryService.createDeployment()
                .addClasspathResource("amedical/medical.bpmn")
                .name("测试Spring流程部署")
                .deploy();
    }
}

执行效果:
