依賴：

dependencys目錄下增加：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

project 節點下新增：

<build>
    <plugins>
        <plugin>
            <groupId>
 
org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <dependencies>
                <!-- spring熱部署-->
                <dependency>
                    <groupId>org.springframework</groupId>
                    <artifactId>
 
springloaded</artifactId>
                    <version>1.2.1.RELEASE</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>

當系統通過 mvn spring-boot:run啟動或者 右鍵application debug 啟動java檔案時，系統會監視classes檔案，當有classes檔案被改動時，系統會重新載入類檔案，不用重啟啟動服務

ps：需要重新編譯檔案 ctl+shift+f9
