CASE1. josnView 를 이용하여 Ajax 설정방법

CASE2. @ResponseBody 를 이용하여 Ajax 설정방법

- DispatcherServlet XML 설정파일 - 꼭필요하다

@RequestMapping(value = "/goAjax1.do", method = RequestMethod.POST)  public @ResponseBody Map<string, object=""> goAjax1() throws Exception {   Map map = new HashMap<string, object="">();   map.put("AA", "1");   map.put("BB", "2");   map.put("CC", "3");   map.put("DD", "4");   return map;  }     @RequestMapping(value = "/goAjax2.do", method = RequestMethod.POST)  @ResponseBody  public Map<string, object=""> goAjax2() throws Exception{   Map map = new HashMap<string, object="">();   map.put("AA", "1");   map.put("BB", "2");   return map;  } </string,></string,></string,></string,>

CASE3. @Controller 를 @RestController 으로 변경함 Spring 4.0은 @Controller와 @ResponseBody 을 합쳐놓은것 이상의 역할을 수행함
