RequestMapping中的两个值必须相同。因此，您必须为每个值定义一个GET和一个POST。
@RequestMapping(value="/rest/greetMe", method= RequestMethod.GET)public @ResponseBody Greeting sayHello( @RequestParam(value = "name", required = false, defaultValue = "Stranger") String name, @RequestParam(value = "language", required = false, defaultValue = "en") String language) { return new Greeting(counter.incrementAndGet(), String.format(getTemplate(language), name));}@RequestMapping(value="/rest/greetMe", method= RequestMethod.POST)public @ResponseBody Greeting sayHello( @RequestBody(required = true) Input input) { return new Greeting(counter.incrementAndGet(), String.format(getTemplate(input.getLanguage()), input.getName()));}
