springmvc传递json数据到前台显示

需要两个包 jackson-core-asl, jackson-mapper-asl

controller

@RequestMapping(value="/findEduList",produces="application/json;charset=UTF-8")
@ResponseBody
public List<Education> findEduList(String keyword, HttpServletRequest request,HttpServletResponse response){
	List<Education> eduList = eduService.findEduList(keyword);
	return eduList;
}

jsp文件
