看起来像官方 swagger for openapi 规范 V3 支持即将发布 https://blog.readme.io/an-example-filled-guide-to-swagger-3-2/，并且 swagger-codegen 已经开发了 3.0.0 支持并通过了一定程度的测试 https://github.com/swagger-api/swagger-codegen

looks like official swagger for openapi specification V3 support is near release https://blog.readme.io/an-example-filled-guide-to-swagger-3-2/, and the swagger-codegen has 3.0.0 support developed and passing some level of testing https://github.com/swagger-api/swagger-codegen on the 3.0.0 branch

我有一个 swagger 规范(通过 https://github.com/mermade/swagger2openapi 从我现有的 2.0 规范生成，输出看起来不错)

I have a swagger spec (generated from my existing 2.0 spec via https://github.com/mermade/swagger2openapi, output looks good)

有没有一种简单的方法来运行 swagger-codegen 而不必自己打包 jar?

Is there an easy way to run the swagger-codegen without having to package the jar myself?

这是我找到的唯一结果:https://oss.sonatype.org/content/repositories/snapshots/io/swagger/swagger-codegen-cli/3.0.0-SNAPSHOT/ 但运行似乎被破坏了(来自输出，可能实际运行的是 2.0 而不是 3.0.0?): this is the single result i found: https://oss.sonatype.org/content/repositories/snapshots/io/swagger/swagger-codegen-cli/3.0.0-SNAPSHOT/ but running that seems to be broken (from the output, possibly actually running 2.0 not 3.0.0?):

看起来 swagger-codegen repo 有一种在某种程度上受支持的方式来运行 docker 容器在你构建之后；我只是希望/猜测有一种支持的方式来执行此操作，而无需在本地编译，因为我需要在多个地方进行设置.

It looks like the swagger-codegen repo has a somewhat supported way to run a docker container after you build; I'm just hoping/guessing there is a supported way to do this without needing to compile locally, as I need to set this up in several places.

推荐答案

OpenAPI Generator(由Swagger Codegen) 支持 OpenAPI 规范 v2 和 v3.

OpenAPI Generator (found by top contributors of Swagger Codegen) supports both OpenAPI specification v2 and v3.

您可以使用 docker 镜像，Java JAR (SNAPSHOT),Brew 或 npm 试试看.

You can use the docker images, Java JAR (SNAPSHOT), Brew or npm to give it a try.
