二、activiti.cfg.xml配置文件

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.2.xsd
         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">

     <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
         <!-- 数据库连接属性 -->
         <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti?characterEncoding=utf-8"></property>
         <property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>
         <property name="jdbcUsername" value="root"></property>
         <property name="jdbcPassword" value="root"></property>

         <!-- 数据库更新策略 -->
         <property name="databaseSchemaUpdate" value="true"></property>

         <property name="jobExecutorActivate" value="false"></property>

         <!-- 邮件服务地址 -->
         <property name="mailServerHost" value="mail.wxintl.com"></property>
         <property name="mailServerPort" value=""></property>
     </bean>

 </beans>

三、log4j.properties配置文件

 # Global logging configuration
 log4j.rootLogger=INFO, Console, OneFile,HtmlFile

 #log4j.logger.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
 #log4j.logger.org.hibernate.type.descriptor.sql.BasicExtractor=TRACE
 #log4j.logger.org.hibernate.tool.hbm2ddl=DEBUG
 #log4j.logger.org.hibernate.SQL=DEBUG

 log4j.appender.Console=org.apache.log4j.ConsoleAppender
 log4j.appender.Console.Target=System.out
 log4j.appender.Console.layout=org.apache.log4j.PatternLayout
 log4j.appender.Console.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

 log4j.appender.OneFile=org.apache.log4j.RollingFileAppender
 log4j.appender.OneFile.File=../activiti.log
 log4j.appender.OneFile.MaxFileSize=10MB
 log4j.appender.OneFile.Threshold=ALL
 log4j.appender.OneFile.layout=org.apache.log4j.PatternLayout
 log4j.appender.OneFile.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

 log4j.appender.HtmlFile=org.apache.log4j.DailyRollingFileAppender
 log4j.appender.HtmlFile.file=../activiti_log
 log4j.appender.HtmlFile.DatePattern='_'yyyy-MM-dd'.html'
 log4j.appender.HtmlFile.layout=org.apache.log4j.HTMLLayout
 log4j.appender.HtmlFile.Threshold=ALL

四、创建核心对象 ProcessEngine

private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

五、发布流程

 @Test
     public void testDeployProcess() {
         RepositoryService repositoryService = processEngine.getRepositoryService();
         // 创建发布对象
         DeploymentBuilder builder = repositoryService.createDeployment();
         // 加载发布资源
         builder.addClasspathResource("leave.bpmn").addClasspathResource("leave.png");
         // 发布资源
         builder.deploy();
     }

六、启动流程

 @Test
     public void testStartProcess() {
         RuntimeService runtimeService = processEngine.getRuntimeService();
         runtimeService.startProcessInstanceByKey("myProcess");
     }

七、查看任务

 @Test
     public void testQueryTask() {
         TaskService taskService = processEngine.getTaskService();
         //String assignee = "employee";
         String assignee = "manager";
         List<Task> tasks = taskService.createTaskQuery().taskAssignee(assignee).list();
         for (Task task : tasks) {
             logger.info("ID:" + task.getId());
             logger.info("Name:" + task.getName());
             logger.info("Assignee:" + task.getAssignee());
             logger.info("CreateTime:" + task.getCreateTime());
         }
     }

八、处理任务

 @Test
     public void testCompleteTask(){
         TaskService taskService = processEngine.getTaskService();
         String taskId = "";
         taskService.complete(taskId);
     }
