spring boot1.1 idea + springboot + mybatis（mybatis-generator） +mysql +html实现简单的登录注册

前言

---

 

这两年springboot比较火，而我平时的工作中不怎么使用spring boot，所以工作之余就自己写写项目练练手，也跟大家一起学习。

打算从最开始的搭架子，登录注册，到后台管理的增删改查，业务逻辑，引用权限框架，如果能一直坚持下去就再增加缓存，中间件，消息队列，数据库方面分库分表，负载均衡这些比较主流的东西都玩一遍。

页面基本上都是在网上找的免费模板，也会借鉴一下其他的博客，如果引用较多会挂上原文链接。

这里引用一篇阿里云的文章，有兴趣的朋友可以去看一看，是spring boot的介绍和使用。

创建项目，用的JDK版本是1.8，

 

 

 

 

 

 

 

 

 

 

项目结构

 

 

 

js css这些资源要放在static包下，我放别的地方引用不进去，后文再说。

 说一下遇到的一些问题

由于第一次使用springboot项目，暂时只会用 thymeleaf 这个东西来使用页面，页面必须要放在templates下，静态资源必须放在static下。

html里要加代码    <html lang="zh-CN" xmlns:th="http://www.thymeleaf.org">  ，

引css： <link rel="stylesheet" type="text/css" th:href="@{/css/style.css}"> ，

引js: <script th:src="@{/js/index.js}"></script>,

而且跳页的时候两个页面之间好像不能互相跳，只能用下面这种方式先请求后台在返回 ModelAndView，因为在controller中用了  @RestController  注解，如果直接return “页面路径” 的话会输出字符串，用重定向好像也没成功，只能用 ModelAndView 这种方式。

如果有了解别的方法的可以留言，还有就是必须要使用 thymeleaf 这种方式吗，我的页面和静态资源正常来说想放在任何包下都可以吧。

  a标签      <a th:href="@{/toPage(url=sign-up2.html)}" >

  后台方法  （方法名应该改一下，当时没注意）

    /**
     * html 页面之间的跳转   th:href="@{/toPage(url=sign-up2.html)}"
     * @param request
     * @return
     */
    @RequestMapping(value = "/toPage",method = RequestMethod.GET)
    public ModelAndView ModelAndView(HttpServletRequest request){
        String url = request.getParameter("url");
        return new ModelAndView(url);
    }

不知道是不是只有这一种方法，有人还知道别的方法的话可以留个言。

 

在项目中创建了一个公共的html，为了抽取一些公用js，代码如下：

headJs.js

<html lang="zh-CN">
<html lang="zh-CN" xmlns:th="http://www.thymeleaf.org">
<div th:fragment="common_js(scripts)">

    <script th:src="@{/js/jquery.min.js}"></script>

    <!--jquery验证插件 -->
    <script th:src="@{http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js}"></script>

    <script th:src="@{/js/bootstrap.min.js}"></script>

    <script th:src="@{/js/jquery.placeholder.min.js}"></script>

    <script th:src="@{/js/jquery.waypoints.min.js}"></script>

    <script th:src="@{/js/main.js}"></script>

    <!-- Modernizr JS -->
    <script th:src="@{/js/modernizr-2.6.2.min.js}"></script>
    <script th:src="@{/js/respond.min.js}"></script>

    <!--/* Per-page placeholder for additional js */-->
   <!-- <th:block th:replace="${scripts}" />-->

</div>
</html>

 

引入方式

    <!--公有js-->
    <div th:replace="headJs::common_js(~{::script})">
    </div>

 

 

还有要注意springboot的启动类  MinimalProjectApplication 必须要放在项目根目录，
