[githubgogogo]

Description

When I use swagger-codegen-maven-plugin maven plugin to generate API java code, the Map is not imported. I saw some similar issue raised but no code fix merged in master branch, could you please let me know when could the fix merged in master branch.

Swagger-codegen version

2.4.0-SNAPSHOT

Swagger declaration file content or url

• name: searchCriteria
  required: false
  in: query
  type: object
  additionalProperties: {
  type: string
  }

Suggest a fix/enhancement

Please support Map in code generation

I faced the same issue with swagger-codegen-maven-plugin 2.3.1

I'm also still seeing this behavior in both 2.3.1 and 2.4.2.

default ResponseEntity<Map<String, MyObject>>.. is generated, but import java.util.Map; is missing.

One possible workaround I've found is to define a wrapper object to be the host of the actual map, which isn't idea, but does work.

hello @githubgogogo @yuanpli @mccrackend

can you please let me know what language are you using to get the issue?

[mccrackend]

@HugoMario I'm using Java v1.8 in this particular project

[HugoMario]

@mccrackend sorry for confuse, i meant what language option for code generation, example: java, spring, python, etc

[mccrackend]

@HugoMario <language>spring</language> sorry about that!
