Spring optional rest endpoint path variable with multiple path variables

Question

How can I have an optional path variable when I have multiple path variables?

This is not working: (organizationName is optional parameter)

  @GetMapping("/organizationreport/{month}/{year}/{organizationName}")
  public ResponseEntity<OrganizationReportJson> getOrganizationReport(
      @PathVariable("month") String month,
      @PathVariable("year") String year,
      @PathVariable Optional<String> organizationName) {

I get 404, wenn calling endpoint without organizationName

Answer 1

在路径变量中添加所需的属性，如下所示。

@PathVariable(required = false) String organizationName
