yan-master项目集成Activiti 6.0.0

1. yan-service模块pom.xml文件中添加Activiti 6.0.0依赖

   pom.xml
   
   <!--添加 activiti-engine 依赖包 -->
   <dependency>
       <groupId>org.activiti</groupId>
       <artifactId>activiti-engine</artifactId>
       <version>6.0.0</version>
   </dependency>
   
   <!-- 添加 activiti-spring 依赖包 -->
   <dependency>
       <groupId>org.activiti</groupId>
       <artifactId>activiti-spring</artifactId>
       <version>6.0.0</version>
   </dependency>

2. yan-service\src\main\resources\META-INF\spring目录下添加Activiti配置文件spring-activiti-context.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
   http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
   
      <!-- spring负责创建流程引擎的配置文件 -->
      <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
         <!-- 数据源 -->
         <property name="dataSource" ref="dataSource" />
         <!-- 配置事务管理器，统一事务 -->
         <property name="transactionManager" ref="transactionManager" />
         <!-- 设置建表策略，如果没有表，自动创建表 -->
         <property name="databaseSchemaUpdate" value="true" />
      </bean>
      <!-- 创建流程引擎对象 -->
      <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
         <property name="processEngineConfiguration" ref="processEngineConfiguration" />
      </bean>
      
      <!-- 
      相当于下面的代码
      RepositoryServicie repositoryService = processEngine.getRepositoryService();
      RuntimeServicie repositoryService = processEngine.getRuntimeServicie();
      TaskServicie taskServicie = processEngine.getTaskServicie();
      HistoryServicie historyServicie = processEngine.getHistoryServicie();
       -->
      <!-- 由流程引擎对象，提供的方法，创建项目中使用的Activiti工作流的Service -->
      <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
      <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
      <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
      <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
      <bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
      
   </beans>
   

3. yan-api\src\main\java\com\yan\api新建activiti目录并创建工作流服务WorkflowService.java

   package com.yan.api.activiti;
   
   /**
    * 工作流服务接口
    */
   public interface WorkflowService {
   
   }

4. yan-service\src\main\java\com\yan\service新建activiti目录实现yan-api中的WorkflowService 服务接口WorkflowServiceImpl.java 

   package com.yan.service.activiti;
   
   import com.yan.api.activiti.WorkflowService;
   import org.activiti.engine.*;
   import org.springframework.beans.factory.annotation.Autowired;
   
   /**
    * 工作流服务接口实现类
    */
   public class WorkflowServiceImpl implements WorkflowService {
   
       @Autowired
       private RepositoryService repositoryService;
   
       @Autowired
       private RuntimeService runtimeService;
   
       @Autowired
       private TaskService taskService;
   
       @Autowired
       private FormService formService;
   
       @Autowired
       private HistoryService historyService;
   
   
   
   } 

5. 在yan-service\src\main\resources\META-INF\spring\spring-dubbo-provider.xml 中对WorkflowService服务接口进行注册

   spring-dubbo-provider.xml
   
   <!--工作流服务-->
   <dubbo:service interface="com.yan.api.activiti.WorkflowService" ref="workflowService" timeout="10000"/>
   

6.  重启 yan-service模块中的 com.yan.service.ServiceApp.main() 方法

7. 重启yan-web
