Activiti7工作流引擎：在线流程编辑器Activiti Modoler5.x
一：简介
有的时候我们的流程图需要业务人员自己绘制，然后使用自己绘制的流程图，此时就需要一个在线流程图编辑器需要集成到我们的web系统中。Activiti Modoler是Activiti官方推出的在线流程编辑器。

三：集成前端页面
https://github.com/Activiti/Activiti/tree/5.x 将整个项目下载下来。不同版本的目录结构区别很大，这里使用5.x。
3.1 集成静态文件
- 将\modules\activiti-webapp-explorer2\src\main\webapp目录下的diagram-viewer、editor-app 整个目录、modeler.html 放到resources/static目录下。
- 将\modules\activiti-webapp-explorer2\src\main\resources\stencilset.json 直接放到resources的根目录下，不需要放在stattc目录下。该文件用于国际化。
3.2 适配前端代码
editor-app\app-cfg.js：修改为空
ACTIVITI.CONFIG = {
'contextRoot' : '',
};
src/main/resources/static/editor-app/configuration/toolbar-default-actions.js
// 该方法改造不是必须的
closeEditor: function(services) {
// window.location.href = "./";
if (window.confirm('确定要放弃此次编辑吗？')){
//1、关闭前对于未点击保存的模型做删除处理
var modelMetaData = services.$scope.editor.getModelMetaData();
location.href = "/activiti/model/close/" + modelMetaData.modelId;
//2、返回上一页面
window.history.back(-1);
}
},
$scope.saveAndClose = function () {
$scope.save(function() {
// window.location.href = "./";
window.history.back(-1);//返回上一页面
});
};
3.3 加载静态资源
WebMvc允许加载静态资源
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
//解决 No mapping for GET 访问静态资源问题
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/")
.addResourceLocations("classpath:/META-INF/resources/");
}
}
四：引入Java类
将modules/activiti-modeler项目中的StencilsetRestResource.java(模具集Rest资源)，ModelEditorJsonRestResource.java(模板编辑)，ModelSaveRestResource.java (模型保存) 放在任意包下。
使用下面代码覆盖原来的方法。
/**
* @author Tijs Rademakers
*/
@RestController
public class ModelSaveRestResource implements ModelDataJsonConstants {
protected static final Logger LOGGER = LoggerFactory.getLogger(ModelSaveRestResource.class);
@Autowired
private RepositoryService repositoryService;
@Autowired
private ObjectMapper objectMapper;
@RequestMapping(value = "/model/{modelId}/save", method = RequestMethod.PUT)
@ResponseStatus(value = HttpStatus.OK)
public void saveModel(@PathVariable String modelId, String name, String description, String json_xml,
String svg_xml) {
try {
Model model = repositoryService.getModel(modelId);
ObjectNode modelJson = (ObjectNode) objectMapper.readTree(model.getMetaInfo());
modelJson.put(MODEL_NAME, name);
modelJson.put(MODEL_DESCRIPTION, description);
model.setMetaInfo(modelJson.toString());
model.setName(name);
repositoryService.saveModel(model);
repositoryService.addModelEditorSource(model.getId(), json_xml.getBytes("utf-8"));
InputStream svgStream = new ByteArrayInputStream(svg_xml.getBytes("utf-8"));
TranscoderInput input = new TranscoderInput(svgStream);
PNGTranscoder transcoder = new PNGTranscoder();
// Setup output
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
TranscoderOutput output = new TranscoderOutput(outStream);
// Do the transformation
transcoder.transcode(input, output);
final byte[] result = outStream.toByteArray();
repositoryService.addModelEditorSourceExtra(model.getId(), result);
outStream.close();
} catch (Exception e) {
LOGGER.error("Error saving model", e);
throw new ActivitiException("模型保存失败", e);
}
}
}
五：访问Activiti Editor页面
@RestController
@RequestMapping("/activiti")
public class ActivitiController {
/**
* 创建模型
*/
@RequestMapping("/create")
public void create(HttpServletRequest request, HttpServletResponse response) {
try {
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode stencilSetNode = objectMapper.createObjectNode();
stencilSetNode.put("namespace", "http://b3mn.org/stencilset/bpmn2.0#");
ObjectNode editorNode = objectMapper.createObjectNode();
editorNode.put("id", "canvas");
editorNode.put("resourceId", "canvas");
editorNode.put("stencilset", stencilSetNode);
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
Model modelData = repositoryService.newModel();
ObjectNode modelObjectNode = objectMapper.createObjectNode();
modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, "模型");
modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, "模型描述");
modelData.setMetaInfo(modelObjectNode.toString());
modelData.setName("我的模型");
modelData.setKey("myModel");
//保存模型
repositoryService.saveModel(modelData);
repositoryService.addModelEditorSource(modelData.getId(), editorNode.toString().getBytes("utf-8"));
response.sendRedirect(request.getContextPath() + "/modeler.html?modelId=" + modelData.getId());
} catch (Exception e) {
System.out.println("创建模型失败：");
}
}
}
http://localhost:8080/activiti/create
insert into ACT_GE_BYTEARRAY(ID_, REV_, NAME_, BYTES_, DEPLOYMENT_ID_) values ( ?, 1, ?, ?, ? )
update ACT_RE_MODEL set REV_ = ?, NAME_ = ?, KEY_ = ?, CATEGORY_ = ?, LAST_UPDATE_TIME_ = ?, VERSION_ = ?, META_INFO_ = ?, DEPLOYMENT_ID_ = ?, EDITOR_SOURCE_VALUE_ID_ = ?, EDITOR_SOURCE_EXTRA_VALUE_ID_ = ?, TENANT_ID_ = ?
where ID_ = ? and REV_ = ?
