问题
I have a dropwizard API app and I want one endpoint where I can run the call and also upload and image, these images have to be saved in a directory and then served through the same application context.
Is it possible with dropwizard? I can only find static assets bundles.
回答1:
There is similar question already: Can DropWizard serve assets from outside the jar file?
The above module is mentioned in the third party modules list of dropwizard. There is also official modules list. These two lists are hard to find maybe because the main documentation doesn't reference them.
There is also dropwizard-file-assets which seems new. I don't know which module will work best for your case. Both are based on dropwizard's AssetServlet
If you don't like them you could use it as example how to implement your own. I suspect that the resource caching part may not be appropriate for your use case if someone replace the same resource name with new content: https://github.com/dirkraft/dropwizard-file-assets/blob/master/src/main/java/com/github/dirkraft/dropwizard/fileassets/FileAssetServlet.java#L129-L141
Edit: This is simple project that I've made using dropwizard-configurable-assets-bundle. Follow the instructions in the README.md. I think it is doing exactly what you want: put some files in a directory somewhere on the file system (outside the project source code) and serve them if they exist.
