Description

This is basically same issue as with https://github.com/OpenAPITools/openapi-generator/issues/2053 with the only difference that this occurres when using path instead of query parameter.

Server fails to parse LocalDate because format annotation is missing in the generated code.

openapi-generator version 4.3.1

OpenAPI declaration file content or url

  /foo/{date}:
    get:
      parameters:
        - name: "date"
          in: "path"
          required: true
          schema:
            type: string
            format: date
            example: 2020-01-15
      responses:
        200:
          description: ""
          content:
            application/json:
              schema:
                type: string

produces

default ResponseEntity<String> fooDateGet(@ApiParam(value = "",required=true) @PathVariable("date") LocalDate date) {
}

causes error:

Failed to covert 2020-08-06 to type:java.time.LocalDate. Text '2020-08-06' could not be parsed at index 4

Related issues/PRs

Same issue as in https://github.com/OpenAPITools/openapi-generator/issues/2053 but for path parameters

Suggest a fix

Same fix from https://github.com/OpenAPITools/openapi-generator/issues/2053 to be applied to in: path parameters

should be

default ResponseEntity<String> fooDateGet(@ApiParam(value = "",required=true) @PathVariable("date")  @org.springframework.format.annotation.DateTimeFormat(iso = org.springframework.format.annotation.DateTimeFormat.ISO.DATE) LocalDate date) {
}

Start with the provided OpenAPI declaration and generated Spring Boot method fooDateGet, then compare this path-parameter case with issue 2053. Reproduce the generated code and verify that the LocalDate path parameter includes the required date-format annotation and parses the example value successfully.
