自定义基于HTTP方法的Spring MVC requestBody映射？

Question

My Java 8, Spring boot 1.4 application has a controller method consuming application/json (jackson 2.6.5) as

public MyModel updateModel(@Valid @RequestBody( required = true) MyModel myModel) {
....
}

And within MyModel, I have a field that I want to given auto-generated value when HTTP method = POST, directly use request value when HTTP method = PUT. IS it doable?

Hope I explain it well. Any helps are deeply appreciated

Answer 1

Add an HttpServletRequest parameter and call getMethod() .

See Spring documentation for supported method argument types. Or read the javadoc of @RequestMapping .

You should also specify the HTTP Methods you want your controller method to handle, eg @RequestMapping(method={RequestMethod.POST, RequestMethod.PUT})
