序言

工作流框架基本上是每个比较复杂的OA或ERP系统的标配，同时Activiti又是国内使用最普遍的工作流框架。于是就想着把Activiti整理一下。
由于现在的项目越来越多的使用springboot，因为它太好用了，正如官方所说'开箱即用'，零配置，敏捷开发的利器啊。应运而生，activiti-spring这样的插件就出现了。注意事项：使用activiti-spring一定要注意与springboot的适配，下面推荐的版本经试验无误。

Spring Boot 2.0 集成 Activiti 6.0

废话不多说上代码：
1、pom.xml

      <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-spring</artifactId>
            <version>6.0.0</version>
        </dependency>

2、新建activiti配置文件ActivitiConfig.java

@Configuration
public class ActivitiConfiguration {
 
    @Autowired
    private DataSource dataSource;
    @Autowired
    private PlatformTransactionManager platformTransactionManager;
 
    @Bean
    public SpringProcessEngineConfiguration springProcessEngineConfiguration(){
        SpringProcessEngineConfiguration spec = new SpringProcessEngineConfiguration();
                spec.setDataSource(dataSource);
                spec.setTransactionManager(platformTransactionManager);
        spec.setDatabaseSchemaUpdate("true");
          // 启动自动部署流程
        Resource[] resources = null;
        try {
            resources = new PathMatchingResourcePatternResolver().getResources("classpath*:bpmn/*.bpmn");
        } catch (IOException e) {
            e.printStackTrace();
        }
        spec.setDeploymentResources(resources);
        return spec;
    }
    
    @Bean
    public ProcessEngineFactoryBean processEngine(){
        ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
        processEngineFactoryBean.setProcessEngineConfiguration(springProcessEngineConfiguration());
        return processEngineFactoryBean;
    }

    @Bean
    public RepositoryService repositoryService() throws Exception{
        return processEngine().getObject().getRepositoryService();
    }

    @Bean
    public RuntimeService runtimeService() throws Exception{
        return processEngine().getObject().getRuntimeService();
    }

    @Bean
    public TaskService taskService() throws Exception{
        return processEngine().getObject().getTaskService();
    }

    @Bean
    public HistoryService historyService() throws Exception{
        return processEngine().getObject().getHistoryService();
    }
}

集成完毕！
