#### [spring-loaded][] ####

*  依赖

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
            <version>1.2.5.RELEASE</version>
       </dependency>

> ps：据说此方法还需要手动编译（`Ctrl + Shift + F9`），请亲测！

#### [spring-boot-devtools][] ####

依赖

<dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-devtools</artifactId>
             <optional>true</optional>
         </dependency>

#### [JRebel][] ####
