java代码

String processDefinitionKey="test:2:0e9648c7997a11e8954f80fa5b3c3420" ;
//        String processDefinitionKey="test" ;
        RuntimeService runtimeService = processEngine.getRuntimeService();
        runtimeService.startProcessInstanceById(processDefinitionKey);

customTaskListener定义在nutz ioc吗?

customTaskListener我没定义，我是直接使用注解注入

@Inject
    private ProcessEngine processEngine;

没有加多余的代码

@wendal

你的意思是没定义customTaskListener? 但流程定义文件里面有写它哦

@wendal
对的，就是这个意思

那就是流程定义的问题...

推荐一本书，叫《Activiti实战》

@wendal 

 Deployment deploy = repositoryService.createDeployment()
                .addClasspathResource("processes/demo2.bpmn").deploy();
        // 启动流程
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("test");
        System.out.println(processInstance.getId());

单机跑demo没问题，流程定义是一模一样的

全局搜customTaskListener

 //添加任务监听

        Map<Object, Object> beans = new HashMap<>();
        ProxyTaskListener proxyTaskListener = new ProxyTaskListener();
        List<TaskListener> taskListeners = new ArrayList<>();
        TaskCategoryTaskListener t1 = new TaskCategoryTaskListener();
        taskListeners.add(t1);
        proxyTaskListener.setTaskListeners(taskListeners);
        beans.put("customTaskListener", proxyTaskListener);
        processEngineConfiguration.setBeans(beans);
        List<BpmnParseHandler> customDefaultBpmnParseHandlers = new ArrayList<>();
        ProxyUserTaskBpmnParseHandler bpmnParseHandler = new ProxyUserTaskBpmnParseHandler();
        bpmnParseHandler.setUseDefaultUserTaskParser(true);
        bpmnParseHandler.setTaskListenerId("customTaskListener");
        customDefaultBpmnParseHandlers.add(bpmnParseHandler);
        processEngineConfiguration.setCustomDefaultBpmnParseHandlers(customDefaultBpmnParseHandlers);
        processEngineConfiguration.setBpmnParser(new CustomBpmnParser());
        //UUID
        processEngineConfiguration.setIdGenerator(new StrongUuidGenerator());
        ProcessEngine processEngine = config.getIoc().get(ProcessEngine.class);
        log.info("Activiti Init End::" + processEngine.getName());

中有

proxyTaskListener.setTaskListeners(taskListeners);
        beans.put("customTaskListener", proxyTaskListener);

这个代理注释掉还是？
