        <!-- 热部署 -->

        <!-- devtools可以实现页面热部署（即页面修改后会立即生效，

                      这个可以直接在application.properties文件中配置spring.thymeleaf.cache=false来实现） -->

        <!-- 实现类文件热部署（类文件修改后不会立即生效），实现对属性文件的热部署。 -->

        <!-- 即devtools会监听classpath下的文件变动，并且会立即重启应用（发生在保存时机），

                    注意：因为其采用的虚拟机机制，该项重启是很快的  -->

        <!-- （1）base classloader （Base类加载器）：加载不改变的Class，例如：第三方提供的jar包。 -->

        <!-- （2）restart classloader（Restart类加载器）：加载正在开发的Class。 -->

        <!-- 为什么重启很快，因为重启的时候只是加载了在开发的Class，没有重新加载第三方的jar包。 -->
