案例代碼：https://gitee.com/flymini/codes01/tree/master/activiti_/learn-activiti03 **** 整合步驟如下： **1. 創建一個Maven項目，`pom.xml`如下** ```xml <properties> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> </properties> <dependencies> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>7.0.0.Beta1</version> </dependency>

<url>https://artifacts.alfresco.com/nexus/content/repositories/activiti-releases/</url> <releases> <enabled>true</enabled> </releases> </repository> </repositories> ``` **2. `resources/activiti-spring.xml`** ```xml <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans

create_drop：在activiti啟動時創建表，在關閉時刪除表（必須手動關閉引擎，才能刪除表）。（單元測試常用） drop-create：在activiti啟動時刪除原來的舊表，然后在創建新表（不需要手動關閉引擎）。 --> <property name="databaseSchemaUpdate" value="drop-create"/> </bean> <!-- 流程引擎 -->

proxy-target-class="true"> <aop:advisor advice-ref="txAdvice" pointcut="execution(*com.itheima.service.impl..(..))"/> </aop:config>--> </beans> ``` **3. 拿到Service服務接口** ```java @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:activiti-spring.xml") public class ActivitiSpringTest { @Autowired private RepositoryService repositoryService; @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Autowired private HistoryService historyService; @Test public void testRep() { //org.activiti.engine.impl.RepositoryServiceImpl@3b9d6699 //成功拿到了RepositoryService，其他服務接口也是一樣 System.out.println(repositoryService); } } ``` 這樣就可以調用不同的接口來完成后續的操作了。
