1 下载 5.22 安装包 ,activiti-5.22.0.rar
7 修改项目webapp\editor-app\app-cfg.js 文件，配置项目url，url是编辑器相关的后台服务的url。myspringmvc是项目名称
Activiti5.22开发 <2> 整合spring和整合编辑器插件（下）
https://github.com/Activiti/Activiti/releases
2 配置项目maven依赖
<!-- activiti-spring -->
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring</artifactId>
<version>${activitti.version}</version>
</dependency>
<!-- activiti-engine -->
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-engine</artifactId>
<version>${activitti.version}</version>
</dependency>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-modeler</artifactId>
<version>${activitti.version}</version>
</dependency>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-diagram-rest</artifactId>
<version>${activitti.version}</version>
</dependency>
3 从activiti-5.22.0.rar中解压 activiti-explorer.war （解压war方法直接改rar）
4 将 activiti-explorer.war 中以下文件夹和文件拷贝到项目webapp中
5 从activiti-5.22.0.rar中目录lib中解压出 activiti-bpmn-model-5.22.0-sources.jar 备用
6 从activiti-explorer.war 目录中 \WEB-INF\classes\stencilset.json 拷贝文件到项目resources 中
'use strict';
var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
//'contextRoot' : '/activiti-explorer/service',
'contextRoot' : '/myspringmvc/service',
};
8 整合modeler模块， activiti-bpmn-model-5.22.0-sources.jar ，一共只有三个Controller类，对应着三个URL，分别是：
StencilsetRestResource /editor/stencilset 用来加载并返回stencilset.json文件的内容
ModelEditorJsonRestResource /model/{modelId}/json 这个就是访问的那个url了，通过部署的modelId模型编辑源
ModelSaveRestResource /model/{modelId}/save 这个是用来保存编辑的模型
9 修改三个Controller类
在每个Controller类上加上@RequestMapping注解，并指定值为"service"（对应前台app-cfg.js中配置的url），例如：StencilsetRestResource类
@RestController
@RequestMapping("/service")
public class StencilsetRestResource {
@RequestMapping(value="/editor/stencilset", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
public @ResponseBody String getStencilset() {
InputStream stencilsetStream = this.getClass().getClassLoader().getResourceAsStream("stencilset.json");
try {
return IOUtils.toString(stencilsetStream, "utf-8");
} catch (Exception e) {
throw new ActivitiException("Error while loading stencil set", e);
}
}
}
10 编写 ModelerController 类，提供新建模型的接口 model/newModel
RestController
@RequestMapping("models")
public class ModelerController implements RestServiceController<Model, String>{
@Autowired
RepositoryService repositoryService;
@Autowired
ObjectMapper objectmapper;
/**
* 新建一个空模型
* @return
* @throws UnsupportedEncodingException
*/
@GetMapping("newModel")
public void newModel(HttpServletRequest request, HttpServletResponse response) throws UnsupportedEncodingException {
//初始化一个空模型
Model model = repositoryService.newModel();
//设置一些默认信息
String name = "new-process";
String description = "";
int revision = 1;
String key = "process";
ObjectNode modelNode = objectmapper.createObjectNode();
modelNode.put(ModelDataJsonConstants.MODEL_NAME, name);
modelNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);
modelNode.put(ModelDataJsonConstants.MODEL_REVISION, revision);
model.setName(name);
model.setKey(key);
model.setMetaInfo(modelNode.toString());
repositoryService.saveModel(model);
String id = model.getId();
//完善ModelEditorSource
ObjectNode editorNode = objectmapper.createObjectNode();
editorNode.put("id", "canvas");
editorNode.put("resourceId", "canvas");
ObjectNode stencilSetNode = objectmapper.createObjectNode();
stencilSetNode.put("namespace",
"http://b3mn.org/stencilset/bpmn2.0#");
editorNode.put("stencilset", stencilSetNode);
repositoryService.addModelEditorSource(id,editorNode.toString().getBytes("utf-8"));
try {
response.sendRedirect(request.getContextPath() + "/modeler.html?modelId=" +id);
} catch (IOException e) {
e.printStackTrace();
}
}
}
