eclipse hot deployment springboot

1. Add dependency to POM file

<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>

2. Add plugin to POM file

<build>
		<finalName>${finalName}</finalName>
		<outputDirectory>${project.basedir}/src/main/webapp/WEB-INF/classes/</outputDirectory>
		<plugins>
			<!-- Spring Boot -->
			<!-- <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> 
				<configuration> &lt;!&ndash;如果没有fork配置,devtools不起作用，即项目修改后不会重新启动 &ndash;&gt; 
				<fork>true</fork> </configuration> </plugin> -->
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<fork>true</fork>
				</configuration>
			</plugin>
