最近公司的項目須要升級acitiviti到flowable，作了好多的準備工做，總結一下，分享給須要愛學習的人。mongodb

1.修改配置文件數據庫

flowable.database-schema-update=truejson

2.從 act_re_model 複製到 act_de_model架構

INSERT INTO act_de_model(id,NAME,model_key,last_updated,created,VERSION,tenant_id,model_type,model_editor_json,created_by,last_updated_by) SELECT id_ AS id,name_ AS NAME,key_ AS model_key,LAST_UPDATE_TIME_ AS last_updated,CREATE_TIME_ AS created,VERSION_ AS VERSION,TENANT_ID_ AS tenant_id,0 AS model_type,META_INFO_ AS model_editor_json, 'admin' as created_by,'admin' as last_updated_by FROM act_re_model;併發

3.同步model的數據app

@Test
    public void testSyncModelDatas() throws Exception {
        List<Model> list = repositoryService.createModelQuery().list();
        int i = 0;
        for (org.flowable.engine.repository.Model model : list) {
            i++;
            byte[] modelEditorSource = repositoryService.getModelEditorSource(model.getId());
            org.flowable.ui.modeler.domain.Model m = modelService.getModel(model.getId());
            if (m != null) {
                try {
                    JsonNode editorNode = new ObjectMapper().readTree(modelEditorSource);
                    m.setModelEditorJson(editorNode.toString());
                    modelService.saveModel(m);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }

4.監聽器兼容處理dom

public class BusinessCallListener implements TaskListener {

    private static final long serialVersionUID = -5140234938739863473L;
    protected Logger logger = LoggerFactory.getLogger(getClass());
    /**
     * dubbo的類名
     */
    private Object clazzName; /** * 方法名 */
    private Object method; /** * 版本號 */
    private Object version; /**
     * 參數 多個的話用分號隔開 實例 userCode:00004737;status:1
     */
    private Object params;

    @Override
    public void notify(DelegateTask delegateTask)  {
        String clazzNameStr = "";
        String methodStr = "";
        String versionStr = "";
        String paramsStr = "";
        if (clazzName instanceof FixedValue){ clazzNameStr = ((FixedValue) clazzName).getExpressionText(); }else if(clazzName instanceof org.activiti.engine.impl.el.FixedValue) { clazzNameStr = ((org.activiti.engine.impl.el.FixedValue) clazzName).getExpressionText(); } if (method instanceof FixedValue){ methodStr = ((FixedValue) method).getExpressionText(); }else if(method instanceof org.activiti.engine.impl.el.FixedValue) { methodStr = ((org.activiti.engine.impl.el.FixedValue) method).getExpressionText(); } if (version instanceof FixedValue){ versionStr = ((FixedValue) version).getExpressionText(); }else if(version instanceof org.activiti.engine.impl.el.FixedValue) { versionStr = ((org.activiti.engine.impl.el.FixedValue) version).getExpressionText(); } if (params instanceof FixedValue){ paramsStr = ((FixedValue) params).getExpressionText(); }else if(params instanceof org.activiti.engine.impl.el.FixedValue) { paramsStr = ((org.activiti.engine.impl.el.FixedValue) params).getExpressionText(); }

        IDynamDubbo dynamDubbo = SpringContextHolder.getBean("dynamDubboImpl");
        ExecutionEntity execution = ExecutionHelper.getExecution(delegateTask.getProcessInstanceId());
        String businessKey = execution.getBusinessKey();
        try {
            Map<String, Object> paramMap = new HashMap<>();
            paramMap.put("businessKey", businessKey);
            if (StringUtils.isNotBlank(paramsStr)) {
                String[] ps = paramsStr.split(";");
                if (ps != null && ps.length > 0) {
                    for (String p : ps) {
                        String[] split = p.split(":");
                        if (split != null && split.length > 0) {
                            paramMap.put(split[0], split[1]);
                        }
                    }
                }
            }
            String paramsJson = JsonUtils.toJson(paramMap);
            //執行dubbo方法
            logger.debug("開始調用業務系統接口" + clazzNameStr + "." + methodStr + ",業務參數:" + paramsJson);
            dynamDubbo.invoke(clazzNameStr, methodStr, versionStr, paramsJson);
        } catch (Exception e) {
            logger.error("調用業務系統的方法失敗", e);
            //添加容錯信息
            FlowBuesinessException fbe = new FlowBuesinessException(clazzNameStr,
                    methodStr, versionStr, businessKey, e.getMessage());
            this.createWfBuesinessException(fbe);
        }
    }

    //添加容錯信息
    private void createWfBuesinessException(FlowBuesinessException fbe){
        IFlowBuesinessExceptionService flowBuesinessExceptionService = SpringContextHolder.getBean("flowBuesinessExceptionServiceImpl");
        try {
            flowBuesinessExceptionService.insertFlowBuesinessException(fbe);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
