最近公司的專案需要升級acitiviti到flowable，做了好多的準備工作，總結一下，分享給需要愛學習的人。

1.修改配置檔案

flowable.database-schema-update=true

2.從 act_re_model 複製到 act_de_model

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;

3.同步model的資料

@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.監聽器相容處理

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;
    /**
     * 引數 多個的話用分號隔開 例項 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("開始呼叫業務系統介面" + clazzNameStr + "." + methodStr + ",業務引數:" + paramsJson);
            dynamDubbo.invoke(clazzNameStr, methodStr, versionStr, paramsJson);
        } catch (Exception e) {
            logger.error("呼叫業務系統的方法失敗", e);
            //新增容錯資訊
            FlowBuesinessException fbe = new FlowBuesinessException(clazzNameStr,
                    methodStr, versionStr, businessKey, e.getMessage());
            this.createWfBuesinessException(fbe);
        }
    }

    //新增容錯資訊
    private void createWfBuesinessException(FlowBuesinessException fbe){
        IFlowBuesinessExceptionService flowBuesinessExceptionService = SpringContextHolder.getBean("flowBuesinessExceptionServiceImpl");
        try {
            flowBuesinessExceptionService.insertFlowBuesinessException(fbe);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

5. flowable-ui-modeler 整合

這個太多了，後面做一個系統講解

6.整合效果

6.1 自定義表單

6.2 流程線上編輯
