我有 Spring Boot 项目，我想记录它的 Rest Controller。我已经在项目中添加了招摇，当我在浏览器中访问 url http://localhost:5053/pmt/v2/api-docs 时，它会正确生成 json，因为我在 application.properties 中定义了以下属性：
server.servlet.context-path=/pmt
server.port=5053
但是我想要pdf格式的文档。所以我用下面的 pom 创建了另一个 maven 项目

我的期望是因为我使用 http://localhost:5053/pmt/v2/api-docs 作为招摇输入，html & pdf 文件将在相应的输出目录中生成。但没有任何事情发生。我错过了什么？这是Maven输出：
