<h2 id="单元测试"><a href="#单元测试" class="headerlink" title="单元测试"></a>单元测试</h2><p>我们来为上节中的 hello world！应用进行单元测试。Spring Boot 的单元测试推荐使用 <code>mockmvc</code> 来进行，好处是不用启动服务即可进行测试。首先添加 test 的 maven 依赖, test 的依赖默认是存在的。</p>

<p>在 <code>src/test/</code> 下面新建包 controller ，然后新建类 HelloTest.java。</p>

<p>运行测试方法。</p>
<h2 id="Jsp-Or-Thymeleaf"><a href="#Jsp-Or-Thymeleaf" class="headerlink" title="Jsp Or Thymeleaf"></a>Jsp Or Thymeleaf</h2><p>Spring Boot 推荐使用 Thymeleaf 来代替 Jsp，那么我们先来认识一下 Thymeleaf 是个什么东东</p>
<h3 id="Thymeleaf-是个什么？"><a href="#Thymeleaf-是个什么？" class="headerlink" title="Thymeleaf 是个什么？"></a>Thymeleaf 是个什么？</h3><p>Thymeleaf 是一个跟 Velocity、FreeMarker 类似的模板引擎，它可以完全替代 JSP 。相较与其他的模板引擎，它有如下三个极吸引人的特点：</p>
<ul>
<li>Thymeleaf 在有网络和无网络的环境下皆可运行，即它可以让美工在浏览器查看页面的静态效果，也可以让程序员在服务器查看带数据的动态页面效果。这是由于它支持 html 原型，然后在 html 标签里增加额外的属性来达到模板+数据的展示方式。浏览器解释 html 时会忽略未定义的标签属性，所以 thymeleaf 的模板可以静态地运行；当有数据返回到页面时，Thymeleaf 标签会动态地替换掉静态内容，使页面动态显示。</li>
<li>Thymeleaf 开箱即用的特性。它提供标准和spring标准两种方言，可以直接套用模板实现JSTL、 OGNL表达式效果，避免每天套模板、该jstl、改标签的困扰。同时开发人员也可以扩展和创建自定义的方言。</li>
<li>Thymeleaf 提供spring标准方言和一个与 SpringMVC 完美集成的可选模块，可以快速的实现表单绑定、属性编辑器、国际化等功能。</li>
</ul>
<h3 id="如何应用"><a href="#如何应用" class="headerlink" title="如何应用"></a>如何应用</h3><p> 同样的首先添加 Thymeleaf 的 maven 组件依赖，这就是 Spring Boot 的优点，把所有优秀的组件都集成进来，使用时仅仅添加依赖就可以了。<br> <figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line"><span class="tag"><<span class="name">dependency</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">groupId</span>></span>org.springframework.boot<span class="tag"></<span class="name">groupId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">artifactId</span>></span>spring-boot-starter-thymeleaf<span class="tag"></<span class="name">artifactId</span>></span></span><br><span class="line"><span class="tag"></<span class="name">dependency</span>></span></span><br></pre></td></tr></table></figure></p>
<p> <code>spring-boot-starter-thymeleaf</code> 组件中已经包含了 web 的组件，也可以将 <code>spring-boot-starter-web</code> 依赖删除。</p>
<p> 然后在 <code>resources/templates/</code> 下新建 <code>hello.html</code> <strong>注意</strong>添加头文件 <code>xmlns:th="http://www.thymeleaf.org"</code><br> <figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"><span class="meta"><!DOCTYPE <span class="meta-keyword">html</span>></span></span><br><span class="line"><span class="tag"><<span class="name">html</span> <span class="attr">lang</span>=<span class="string">"en"</span> <span class="attr">xmlns:th</span>=<span class="string">"http://www.thymeleaf.org"</span>></span></span><br><span class="line"><span class="tag"><<span class="name">head</span>></span> ... <span class="tag"></<span class="name">head</span>></span></span><br></pre></td></tr></table></figure></p>
<p>修改 <code>HelloController</code> 与 <code>hello.html</code></p>
