DMN部署： dmn制定了规则之后，还需要部署好才能用

配置规则

这边只是做了一个简单的规则判断，实际业务场景可以设置的更加复杂
这里我们为了简单就是使用first的模式，返回一个数据

部署

public DmnDeployment deploy(DmnModelVo params) {
        DmnDeployment deployment = null;
        try {
            Model model = modelService.getModel(params.getModelId());
            //Model转化为jsonNode对象
            JsonNode editorJsonNode = objectMapper.readTree(model.getModelEditorJson());
            String fileName = URLEncoder.encode(model.getName(), "UTF-8").replaceAll("\\+", "%20") + ".dmn";
            //通过jsonNode转化成DmnDefinition对象
            DmnDefinition dmnDefinition = dmnJsonConverter.convertToDmn(editorJsonNode, model.getId(), 1, null);
            ExtendModel extendModel = extendModelService.getExtendModelByModelKey(model.getKey());
            //必须指定文件后缀名否则部署不成功
            deployment = dmnRepositoryService.createDeployment().name(fileName).tenantId(extendModel.getSystemSn())
                    .addDmnModel(model.getKey() + ".dmn", dmnDefinition)
                    .category(extendModel.getCategoryCode()).deploy();
            //修改状态为已发布
            extendModel.setStatus(ModelFormStatusEnum.YFB.getStatus());
            extendModelService.updateExtendModel(extendModel);
        } catch (Exception e) {
            e.printStackTrace();
            logger.error("部署DMN失败", e);
        }
        return deployment;
    }

使用

Map<String, Object> result = dmnRuleService.createExecuteDecisionBuilder()
                .decisionKey("decision1")
                .variable("departmentCode", "100001")
                .variable("money", "5000")
                .executeWithSingleResult();
assertThat(result)
                .contains(
                        entry("applyer", "李四")
                );
