Swagger-codegen: Path Variable uppercase in RequestMapping but lowercase in PathVariable

[erreobi]

Description

The swagger file contain the following definition (I can't share everything):

`'/pets/{PetId}':

get:
  tags:
    - Pets
  summary: Get a single pet
  description: Get a single pet
  operationId: GetSinglePet
  produces:
    - application/json
  parameters:
    - name: PetId
      in: path
      description: Unique identification of pets.
      required: true
      type: string`

The generated code is:
`

@RequestMapping(value = "/pets/{PetId}",
    produces = { "application/json" }, 
    method = RequestMethod.GET)
ResponseEntity<PetStorePetsSetupPOSTResponse> getSingleImmediatePets(@ApiParam(value = "Unique identification of Pets.",required=true ) @PathVariable("petId") String petId);

`

As you can see, the variable PetId is correct in RequestMapping and wrong in PathVariable.

it causes the following error:
{"timestamp":"2017-04-12T11:16:28.156Z","status":500,"error":"Internal Server Error","exception":"org.springframework.web.bind.MissingPathVariableException","message":"Missing URI template variable 'petId' for method parameter of type String","path":"/robtesting/pets/123"}

I don't want to manually modify the interface, could you please help me to fix this?

Ciao
Roberto

@erreobi may I know which generator is that?

Please try the latest master as we've been fixing path variable naming. Please see https://github.com/swagger-api/swagger-codegen/issues/4898 for more information.

I used the maven plug in swagger-codegen-maven-plugin version 2.2.2
Here is my configuration:
<plugin> <groupId>io.swagger</groupId> <artifactId>swagger-codegen-maven-plugin</artifactId> <version>2.2.2</version> <executions> <execution> <goals> <goal>generate</goal> </goals> <configuration> <inputSpec>src/main/resources/pets.json</inputSpec> <language>spring</language> <apiPackage>com.rob.petstore.swagger.api</apiPackage> <modelPackage>com.rob.petstore.swagger.model</modelPackage> <invokerPackage>com.rob.petstore.swagger.invoker</invokerPackage> <modelNamePrefix>petstore</modelNamePrefix> <useJaxbAnnotations>true</useJaxbAnnotations> <ignoreFileOverride>./swagger-codegen-ignore</ignoreFileOverride> </configuration> </execution> </executions> </plugin>

You will need to build the JAR from the latest master to enjoy the fix (or you can use docker instead)

@wing328 Thanks!!

I can not download it from the public repository, is it my fault? or, when will it be in the public maven repo?

[wing328]

We don't do nightly build for the latest master. Can you try building it locally: mvn clean package? or use docker instead.

[erreobi]

I cloned it and it works fine! Thanks again!

When is it planned to push it in master?
