1、添加依赖

建议使用官方提供的在线地址进行工程的初始化创建：https://start.spring.io

添加Spring Cloud和Spring Cloud Alibaba依赖管理：

<properties>
		<java.version>1.8</java.version>
		<spring-cloud.version>Greenwich.SR3</spring-cloud.version>
		<spring-cloud-alibaba.version>0.9.0.RELEASE</spring-cloud-alibaba.version>
</properties>
	<dependencyManagement>
		<dependencies>
			<!--Spring Cloud -->
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
			<!--Spring Cloud Alibaba -->
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-alibaba-dependencies</artifactId>
				<version>${spring-cloud-alibaba.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>
