静态资源要放在web/stastics文件夹下\r\n - jsp文件要放在WEB-INF/jsp文件夹下，index.jsp除外\r\n - **记住一定要为WEB-INF下的lib添加相关的jar包**\r\n - 如果修改或添加静态资源后确定静态资源的加载路径没有错的情况下还出现静态资源加载出错，就尝试重启一下IDEA\r\n - ajax的中文返回值乱码问题可以尝试用@RequestMapping(value = \"**\",produces = \"text/html;charset=UTF-8\")注解解决\r\n - 常用注解有：@Controller、@RequestMapping、@ResponseBody、@Autowired、@Qualifier\r\n - 新建的jsp文件记得添加<%@ taglib prefix=\"c\" uri=\"http://java.sun.com/jsp/jstl/core\" %>\r\n - lombok需要下载插件才能使用\r\n \r\n\r\n参考至https://blog.kuangstudy.com/index.php/archives/487/',1,'2020-02-20
