Session的写入与获取

基本配置

// SessionAttributes只能设置在类上
@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张国");
		
		// 设置请求属性
		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获取

	@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获取

	/**

	 */
	@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;
	}
