Spring AOP 메서드 추적 Flow
Spring AOP를 활용한 메소드 흐름을 로깅한 로직을 정리합니다.

Spring Ajax 설정
JsonView 설정을 이용하여 AJAX를 사용할 수 있게 설정하는 과정을 포스트 합니다.
pom.xml과 dispatcher에는 기본적으로 등록
pom.xml
net.sf.json-lib json-lib 2.4 jdk15 org.codehaus.jackson jackson-mapper-asl 1.6.4 DispatcherServlet XML 설정파일
action *.do action *.ajax @RequestMapping("/test.do")
public String test(@ModelAttribute("searchVO") CommentVO commentVO, ModelMap model) throws Exception {
return "test/test";
}
@RequestMapping("/test.ajax")
public ModelAndView testAjax(@ModelAttribute("searchVO") CommentVO commentVO, ModelMap model) throws Exception {
Map resultMap = new HashMap();
resultMap.put("result1", "test1");
resultMap.put("result2", "test222");
ModelAndView modelAndView = new ModelAndView("jsonView",resultMap);
return modelAndView;
