Java 无法使用springdoc openapi maven插件生成Swagger.json文件

我试图在maven构建期间生成Swagger.json文件

这是我的pom.xml插件

我已经尝试了所有关于stackoverflow问题的答案，但不幸的是，没有一个对我有用

任何帮助都将不胜感激。

您的应用程序似乎没有在8080端口上运行。检查您的Spring配置，可能您设置了不同的端口？

Openapi.json文件是在将application.properties的一些配置从test文件夹移动到src文件夹中的bootstrap.properties之后生成的。但每次生成json文件时，我都必须关闭端口9001。

我检查了端口号，它只有8080。我想在maven build.Ok期间生成swagger.json。我想说apiDocsUrl有点问题。这应该是springdoc API端点，而不是您自己的端点。我会删除配置中的apiDocsUrl元素。通常不需要，因为默认值将正常工作。如果默认设置不起作用，那么您已经在某个地方使用不同的端点配置了springdoc，您需要显示该配置。另外，请查看插件的官方自述文件：我看到您的pom存在这些差异：该版本目前已经是1.1。您的配置中缺少JVM参数元素。是的，我尝试了与文档所述相同的插件，但也不起作用。在这个repo中，我把插件放在pom中，但我没有推，因为它不工作。在你的repo中，你把端口设置为8083，但上面你告诉我它是8080。是哪一个？看见
