springboot集成devtools热加载

在pom.xml里面加上jar

<!-- spring-boot-devtools 热加载-->
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-devtools</artifactId>
		<optional>true</optional> <!-- 表示依赖不会传递 -->
	</dependency>

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
					<fork>true</fork> <!-- 如果没有该配置，devtools不会生效 -->
				</configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>   
                <groupId>org.apache.maven.plugins</groupId>   
                <artifactId>maven-war-plugin</artifactId>   
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                    <warName>${artifactId}</warName>
                </configuration>   
		   </plugin>   
        </plugins>
        <finalName>${artifactId}</finalName>
    </build>

然后在yml里面配置devtools开关

spring:
  
  # 服务模块
  devtools:
    restart:
      # 热部署开关
      enabled: true

就是这么简单，设置enabled为true后，你写完代码保存后就是重启项目
