Description

Description

Currently, Java does not support Map of Map of String or other type

public class MapTest   {
  @SerializedName("map_map_of_string")
  private Map<String, Map<String, String>> mapMapOfString = new HashMap<String, Map<String, String>>();

As shown above, the inner Map is not mapped to HashMap

Suggest a Fix

The issue likely has to do with getTypeDeclaration in modules/swagger-codegen/src/main/java/io/swagger/codegen/languages/AbstractJavaCodegen.java

Contributor guide

Research direction
Examine the getTypeDeclaration method in AbstractJavaCodegen.java to add support for nested Map types like Map<String, Map<String, String>>.
