springboot.2.x 与Spring 集成activiti 的区别

springboot 2.x 集成activiti 6.0 ，通过activiti-spring-boot-start-basic-\*.jar 完成SpringProcessEngineConfiguration.java（流程引擎配置参数） 、ProcessEngine（流程引擎）.java 、RepositoryService（部署对象实例化）.java、RuntimeService（运行对象实例化）.java、TaskService（运行对象实例化）.java、HistoryService（历史任务对象实例化）.java、FormService（ 表单对象实例化）.java 。

相关流程如下截图：

如果是spring 集成activiti 就需要添加如下代码：

package com.zzg.activiti.config;
    
    import javax.sql.DataSource;
    
    import org.activiti.engine.FormService;
    import org.activiti.engine.HistoryService;
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.RepositoryService;
    import org.activiti.engine.RuntimeService;
    import org.activiti.engine.TaskService;
    import org.activiti.spring.ProcessEngineFactoryBean;
    import org.activiti.spring.SpringProcessEngineConfiguration;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.transaction.PlatformTransactionManager;
    /**
     * activiti 流程配置
     * @author zzg
     *
     */
    @Configuration
    public class ActivitiConfig {
    	
    	// 日志管理
    	private Logger logger = LoggerFactory.getLogger(ActivitiConfig.class);
    	
    	
    	@Autowired
    	private DataSource dataSource;
    	
    	@Autowired
    	private PlatformTransactionManager transactionManager;
    	
    	/**
    	 * activiti 处理引擎配置参数实列化对象
    	 * @return
    	 */
    	@Bean
    	public SpringProcessEngineConfiguration processEngineConfig(){
    		SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
    		// 数据源设置
    		processEngineConfiguration.setDataSource(dataSource);
    		// 事务管理器
    		processEngineConfiguration.setTransactionManager(transactionManager);
    		return processEngineConfiguration;
    	}
    	
    	/**
    	 * activiti 处理引擎实列化对象
    	 * @return
    	 */
    	@Bean
    	public ProcessEngine processEngine(){
    		ProcessEngine processEngine= null;
    		ProcessEngineFactoryBean factory = new ProcessEngineFactoryBean();
    		factory.setProcessEngineConfiguration(processEngineConfig());
    		try {
    			processEngine = factory.getObject();
    		} catch (Exception e) {
    			// TODO Auto-generated catch block
    			logger.error(e.getMessage());
    			return null;
    		}
    		return processEngine;
    	}
    	/**
    	 * activiti 部署对象实例化
    	 */
    	@Bean
    	public RepositoryService getRepository(){
    		return processEngine().getRepositoryService();
    	}
    	
    	/**
    	 * activiti 运行对象实例化
    	 */
    	@Bean
    	public RuntimeService getRuntime(){
    		return processEngine().getRuntimeService();
    	}
    	
    	/**
    	 * activiti 任务对象实例化
    	 */
    	@Bean
    	public TaskService getTask(){
    		return processEngine().getTaskService();
    	}
    	
    	/**
    	 * activiti 历史任务对象实例化
    	 * @return
    	 */
    	@Bean
    	public HistoryService getHistory(){
    		return processEngine().getHistoryService();
    	}
    	
    	/**
    	 * activiti 表单对象实例化
    	 * @return
    	 */
    	@Bean
    	public FormService getForm(){
    		return processEngine().getFormService();
    	}
    	
    	
    	
    	
    
    }

功能流程上无太多区别，只是一个是自动注入另一种方式是硬编码。
