boot-admin 是一款采用前后端分离模式、基于SpringCloud微服务架构的SaaS后台管理框架。系统内置基础管理、权限管理、运行管理、定义管理、代码生成器和办公管理6个功能模块，集成分布式事务Seata、工作流引擎Flowable、业务规则引擎Drools、后台作业调度框架Quartz等，技术栈包括Mybatis-plus、Redis、Nacos、Seata、Flowable、Drools、Quartz、SpringCloud、Springboot Admin Gateway、Liquibase、jwt、Openfeign、I18n等。

在上一篇博文中，已经介绍了 boot-admin 对 editor-app 前端代码的集成改造，接下来我们看看后端代码。

提供汉化资源json数据

   /**
     * 获取汉化资源
     * @return
     */
    @RequestMapping(value = "/editor/stencilset", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
    public String getStencilset() {
        InputStream stencilsetStream = this.getClass().getClassLoader().getResourceAsStream("stencilset.json");
        try {
            return IOUtils.toString(stencilsetStream, "utf-8");
        } catch (Exception e) {
            throw new FlowableException("Error while loading stencil set", e);
        }
    }

资源包stencilset.json需放在resources文夹下，这里提供下载：点击下载汉化包

分页获取模型列表

controller：

@RequestMapping("/api/workflow/auth/activiti")
@RestController
@Slf4j
public class ModelController extends BaseController {
    @Resource
    private FormValidator formValidator;
    @Autowired
    private MyModelService modelService;

    @PostMapping("/model/page")
    @ApiOperation("分页获取项目数据表列表")
    public ResultDTO getTablePage(@Valid @RequestBody ModelQueryVO queryVO, BindingResult bindingResult) throws Exception {
        if (bindingResult.hasErrors()) {
            return formValidator.generateMessage(bindingResult);
        }
        return modelService.getPage(queryVO);
    }
}    

service:

    @Override
    public ResultDTO getPage(ModelQueryVO queryVO) throws Exception {
        int offset = (queryVO.getCurrentPage() - 1) * queryVO.getPageSize() + 0;
        List<Model> list = repositoryService.createModelQuery().listPage(offset
                , queryVO.getPageSize());
        int total = (int) repositoryService.createModelQuery().count();
        Page<Model> page = new Page<>();
        page.setRecords(list);
        page.setTotal(total);
        return ResultDTO.success(page);
    }

读取模型数据

controller：

@RequestMapping("/api/workflow/auth/activiti")
@RestController
@Slf4j
public class ModelController extends BaseController {
    @Autowired
    private RepositoryService repositoryService;
    @Autowired
    private ObjectMapper objectMapper;
    /**
     * 获取用于编辑的模型JSON数据
     * @param modelId 模型ID
     * @return
     */
    @GetMapping(value = "/model/json")
    public ObjectNode getEditorJson(@RequestParam("modelId") String modelId) {
        ObjectNode modelNode = null;
        Model model = repositoryService.getModel(modelId);
        if (model != null) {
            try {
                if (StringUtils.isNotEmpty(model.getMetaInfo())) {
                    modelNode = (ObjectNode) objectMapper.readTree(model.getMetaInfo());
                } else {
                    modelNode = objectMapper.createObjectNode();
                    modelNode.put(MODEL_NAME, model.getName());
                }
                modelNode.put(MODEL_ID, model.getId());
                ObjectNode editorJsonNode = (ObjectNode) objectMapper.readTree(
                        new String(repositoryService.getModelEditorSource(model.getId()), "utf-8"));
                modelNode.put("model", editorJsonNode);

            } catch (Exception e) {
                log.error("Error creating model JSON", e);
                throw new FlowableException("Error creating model JSON", e);
