YAML配置的places部分无效。

它应该看起来像这样：

places:
    - draft
    - reviewed
    - published

注意减号和项目名称之间的空格

我进行了更改，以便从类型中删除引号并删除参数，并添加了roved_by_admin，现在它可以正常工作了。

framework:
  workflows:
    article_publishing:
      type: workflow
      audit_trail: true
      marking_store:
        type: multiple_state
      supports:
        - App\Entity\Article
      places:
        - draft
        - for_review
        - approved_by_admin
        - published
      transitions:
        to_for_review:
          from: draft
          to:   for_review
        to_approved_by_admin:
          from: for_review
          to: approved_by_admin
        to_published:
          from: approved_by_admin
          to:   published
        to_draft:
          from: for_review
          to:   draft

然后我将这段代码添加到Controller

/**
     * @Route("/apply-transition/{article}",methods={"POST"})
     */
    public function applyTransition(WorkflowInterface $articleWorkflow,Request $request,Article $article,RouterInterface $router)
    {
        $slug = $article->getCategory()->getSlug();
        try {
            $articleWorkflow->apply($article,$request->request->get('transition'));
            $this->repository->flush();
        } catch (ExceptionInterface $e) {
           echo $e->getMessage();
        }
        $url = $router->generate('app_category_view',([
            'slug' => $slug,]));
        return new RedirectResponse($url);

    }
    /**
     * @Route("/resetMarking/{article}",methods={"POST"})
     */

    public function resetMarking(Article $article,RouterInterface $router)
    {
        $slug = $article->getCategory()->getSlug();
        $article->setMarking([]);
        $this->repository->flush();
        $url = $router->generate('app_category_view',]));
        return new RedirectResponse($url);
    }

在实体中添加此

/**
     * @ORM\Column(type="json_array",nullable=true)
     */
    private $marking;

    /**
     * @ORM\Column(type="json_array",nullable=true)
     */
    private $transitionContexts;
