Session的寫入與獲取
基本配置
// SessionAttributes只能設定在類上
@SessionAttributes(value = {"beanParam"}, types = {BeanParam.class})
public class AttributeController {
@RequestMapping("/setSession") public ModelAndView Session(Long id) { BeanParam beanParam = new BeanParam(); beanParam.setName("zhagnan"); beanParam.setNote("test張國"); // 設定請求屬性 ModelAndView mv = new ModelAndView(); mv.addObject("beanParam", beanParam); mv.setViewName("attribute"); return mv; } @RequestMapping("/getSession") public ModelAndView getSession(@SessionAttribute("beanParam") BeanParam beanParam) { ModelAndView mv = new ModelAndView(); mv.addObject(beanParam); mv.setView(new MappingJackson2JsonView()); return mv; }
Cookie獲取
@RequestMapping("/getCookie")
public ModelAndView getCookie(@CookieValue(value = "JSESSIONID", defaultValue = "mmp") String jsessionId) {
logger.debug("jsessionId: {}", jsessionId);
ModelAndView mv = new ModelAndView();
mv.setViewName("attribute");
return mv;
}
Request Header獲取
/**

* Accept-Encoding: gzip, deflate, br
* Accept-Language: zh-CN,zh;q=0.9

*/
@RequestMapping("/getRequestHeader")
public ModelAndView getRequestHeader(@RequestHeader(value = "Accept-Encoding") String acceptEncoding) {
logger.debug("Accept-Encoding: {}", acceptEncoding);
ModelAndView mv = new ModelAndView();
mv.setViewName("attribute");
return mv;
}
