To my knowledge both serves the same purpose. Except the fact that @PathVariable is from Spring MVC and @PathParam is from JAX-RS. Any insights on this?

@QueryParam is used to access key/value pairs in the query string of the URL (the part after the ?). For example in the url http://example.com?q=searchterm , you can use @QueryParam("q") to get the value of q . @PathParam is used to match a part of the URL as a parameter.
Difference between @PathVariable and @RequestParam in Spring 1) The @RequestParam is used to extract query parameters while @PathVariable is used to extract data right from the URI.
The key difference between @RequestParam and @PathVariable is that @RequestParam used for accessing the values of the query parameters where as @PathVariable used for accessing the values from the URI template.
The @PathVariable annotation is used to extract the value of the template variables and assign their value to a method variable.
@PathVariable and @PathParam both are used for accessing parameters from URI Template
Differences:
@PathVariable is from spring and @PathParam is from JAX-RS.@PathParam can use with REST only, where @PathVariable used in Spring so it works in MVC and REST.
