    三、log4j.properties配置文件

     1 # Global logging configuration
 2 log4j.rootLogger=INFO, Console, OneFile,HtmlFile
 3 
 4 #log4j.logger.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
 5 #log4j.logger.org.hibernate.type.descriptor.sql.BasicExtractor=TRACE

    四、创建核心对象 ProcessEngine

    private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

    五、发布流程

     1 @Test
 2     public void testDeployProcess() {
 3         RepositoryService repositoryService = processEngine.getRepositoryService();
 4         // 创建发布对象
 5         DeploymentBuilder builder = repositoryService.createDeployment();
 6         // 加载发布资源
 7         builder.addClasspathResource("leave.bpmn").addClasspathResource("leave.png");
 8         // 发布资源
 9         builder.deploy();
10     }
    View Code

    六、启动流程

    1 @Test
2     public void testStartProcess() {
3         RuntimeService runtimeService = processEngine.getRuntimeService();
4         runtimeService.startProcessInstanceByKey("myProcess");
5     }
    View Code

    七、查看任务

     1 @Test
 2     public void testQueryTask() {
 3         TaskService taskService = processEngine.getTaskService();
 4         //String assignee = "employee";
 5         String assignee = "manager";
 6         List<Task> tasks = taskService.createTaskQuery().taskAssignee(assignee).list();
 7         for (Task task : tasks) {
 8             logger.info("ID:" + task.getId());
 9             logger.info("Name:" + task.getName());
10             logger.info("Assignee:" + task.getAssignee());
11             logger.info("CreateTime:" + task.getCreateTime());
12         }
13     }
    View Code

    八、处理任务

    1 @Test
2     public void testCompleteTask(){
3         TaskService taskService = processEngine.getTaskService();
4         String taskId = "7502";
5         taskService.complete(taskId);
6     }
