实现spring boot热部署二个步骤

一，加入依赖

<dependency>  
     <groupId>org.springframework.boot</groupId>  
     <artifactId>spring-boot-devtools</artifactId>  
     <!--optional=true,依赖不会传递，该项目依赖devtools；之后依赖myboot项目的项目如果想要使用devtools，需要重新引入-->   
     <optional>true</optional> 
</dependency> 

 <plugin>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-maven-plugin</artifactId>
 </plugin>

<configuration>
     <fork>true</fork>
</configuration>

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>
