新增一个节点属性
新增一个package
{name: nodetypepackage,properties: [{id: nodetype,type: dragon-nodetype-combobox,title: 节点类型,value: ,description: 节点类型,popular: true}]}
把我们新增的这个package添加节点属性中

}编写angularJS脚本
在properties.js 配置模板
“dragon-nodetype-combobox”: {
“readModeTemplateUrl”: “editor-app/configuration/properties/dragonnodetype-combobox-value-template.html”,
“writeModeTemplateUrl”: “editor-app/configuration/properties/dragonnodetype-combobox-property-write-template.html”
}模板的内容 dragonnodetype-combobox-value-template.html 内容为
span{{property.text}}/span
dragonnodetype-combobox-property-write-template.html 内容为 div ng-controllerDragonNodetypeComboboxCtrlselect ng-inititem property.value ng-modelitem ng-changecomboValueChanged(item)ng-optionsitem.sn as item.name for item in nodeTypes/select
/div
编写js控制器
properties-dragon-combobox-controller.js
angular.module(flowableModeler).controller(DragonNodetypeComboboxCtrl,[ $scope, $modal, $http, function($scope, $modal, $http) {if ($scope.property.value undefined $scope.property.value null) {$scope.property.value ;}//请求数据//url 你可以请求你后台的rest接口来获取数据对象$http({method: GET,url: FLOWABLE.URL.getNodeProertyInfos(node_type)}).then(function successCallback(response) {$scope.nodeTypes response.data.data;}, function errorCallback(response) {// 请求失败执行代码});$scope.comboValueChanged function (item) {$scope.property.value item;for (var i 0; i $scope.nodeTypes.length; i) {if ($scope.nodeTypes[i].sn item) {$scope.property.text $scope.nodeTypes[i].name;}}$scope.updatePropertyInModel($scope.property);};}]);
配置引用
在index.html中加入自定的js
后台配置解析我们的节点属性
编写一个自定义的解析器
记住一定要继承UserTaskJsonConverter
public class BruceUserTaskJsonConverter extends UserTaskJsonConverter {public static void fillTypes(MapString, Class? extends BaseBpmnJsonConverter convertersToBpmnMap,MapClass? extends BaseElement, Class? extends BaseBpmnJsonConverter convertersToJsonMap) {fillJsonTypes(convertersToBpmnMap);fillBpmnTypes(convertersToJsonMap);}public static void setCustomTypes(MapString, Class? extends BaseBpmnJsonConverter convertersToBpmnMap,MapClass? extends BaseElement, Class? extends BaseBpmnJsonConverter convertersToJsonMap) {removeTypes(convertersToBpmnMap,convertersToJsonMap);fillTypes(convertersToBpmnMap,convertersToJsonMap);}public static void removeTypes(MapString, Class? extends BaseBpmnJsonConverter convertersToBpmnMap,MapClass? extends BaseElement, Class? extends BaseBpmnJsonConverter convertersToJsonMap) {convertersToJsonMap.remove(UserTask.class);convertersToBpmnMap.remove(StencilConstants.STENCIL_TASK_USER);}public static void fillJsonTypes(MapString, Class? extends BaseBpmnJsonConverter convertersToBpmnMap) {convertersToBpmnMap.put(STENCIL_TASK_USER, BruceUserTaskJsonConverter.class);}public static void fillBpmnTypes(MapClass? extends BaseElement, Class? extends BaseBpmnJsonConverter convertersToJsonMap) {convertersToJsonMap.put(UserTask.class, BruceUserTaskJsonConverter.class);}Overridepublic void convertToJson(BaseElement baseElement, ActivityProcessor processor, BpmnModel model, FlowElementsContainer container, ArrayNode shapesArrayNode, double subProcessX, double subProcessY){super.convertToJson(baseElement, processor, model, container, shapesArrayNode, subProcessX, subProcessY);}Overrideprotected FlowElement convertJsonToElement(JsonNode elementNode, JsonNode modelNode,MapString, JsonNode shapeMap) {UserTask flowElement (UserTask) super.convertJsonToElement(elementNode, modelNode, shapeMap);ListCustomProperty customProperties new ArrayList();// 扩展 节点类型String nodetype getPropertyValueAsString(FlowConstant.NODE_TYPE, elementNode);if (StringUtils.isNotBlank(nodetype)) {CustomProperty nodeType this.createProperty(FlowConstant.NODE_TYPE, nodetype);customProperties.add(nodeType);}if (CollectionUtils.isNotEmpty(customProperties)) {flowElement.setCustomProperties(customProperties);}return flowElement;}/*** 创建自定义属性** param propertyName 属性名称* param propertyValue 属性值*/private CustomProperty createProperty(String propertyName, String propertyValue) {CustomProperty customProperty new CustomProperty();customProperty.setId(propertyName);customProperty.setName(propertyName);customProperty.setSimpleValue(propertyValue);return customProperty;}
}
bean的初始化
public class CustomPropertyInit {public CustomPropertyInit(){MapClass? extends BaseElement, Class? extends BaseBpmnJsonConverter convertersToJsonMap BpmnJsonConverter.convertersToJsonMap;MapString, Class? extends BaseBpmnJsonConverter convertersToBpmnMap BpmnJsonConverter.convertersToBpmnMap;//添加自定义的任务json转化器BruceUserTaskJsonConverter.setCustomTypes(convertersToBpmnMap, convertersToJsonMap);}}
spring定义bean
/*** 自定义节点属性初始化*/Beanpublic CustomPropertyInit createCustomPropertyInit() {return new CustomPropertyInit();}
