二.错误原因因为没有正式环境的入口类,项目结构如下:

pom.xml文件的<build>配置信息如下:

三.解决方案1 pom.xml文件的<build>中指定入口类,代码如下

<configuration>
		<mainClass>com.qfx.App</mainClass>
</configuration>

如图

四.解决方案2 去掉<build>配置信息中spring热部署的配置，如图

五.解决方案3 修改pom.xml配置文件<build>内容如下,添加一个<pluginManagement>标签，代码如下

	<build>
		<finalName>test</finalName>
		<pluginManagement>
			<plugins>
				<plugin>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-maven-plugin</artifactId>
					<dependencies>
						<!-- spring热部署 -->
						<dependency>
							<groupId>org.springframework</groupId>
							<artifactId>springloaded</artifactId>
							<version>1.2.8.RELEASE</version>
						</dependency>
					</dependencies>
				</plugin>
			</plugins>
		</pluginManagement>
	</build>
