[FIXED] What is this strange path syntax?

Issue

One of my colleagues uses = as shown below for path variables and it surprisingly (to me) works. However, I have never seen examples of it in any tutorials.

@GetMapping("/getCustomFieldBy={portId}")
public ResponseEntity getMempools(@PathVariable Long portId) {
    return ResponseEntity.ok(customFieldService.findByPortId(portId));
}

I expect a / inside the pathname. Is there a name for this syntax or is it even standard? How do I look it up?

Solution

It is not a strange syntax, it's a valid and literal mapping of the = character. These are examples of valid endpoints that the mapping intercepts:

• localhost:8080/getCustomFieldBy=8009
• localhost:8080/getCustomFieldBy=15123

It is not a standard nor a convention to use =. A typical REST endpoint would look rather like this:

• localhost:8080/customField?port=8009
