使用maven搭建微服务框架

徒手搭建cloud

1.认准SpringBoot,SpringCloud,SpringCloudAlibaba版本之间的对用关系

官网给出了声明：https://github.com/alibaba/spring-cloud-alibaba/wiki

2.选择好版本之后

spring boot	spring cloud	spring cloud alibaba
2.3.12.RELEASE	Hoxton.SR10	2.2.5.RELEASE

在父工程cloud-parent导入

	<modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>cloud-parent</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.12.RELEASE</version><relativePath/></parent><properties><com.alibaba.cloud>2.2.5.RELEASE</com.alibaba.cloud><spring.boot.version>2.3.12.RELEASE</spring.boot.version><spring-cloud.version>Hoxton.SR10</spring-cloud.version><lombok.version>1.18.8</lombok.version></properties><dependencies><dependency><!-- 排除默认的logback日志，使用log4j--><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-log4j2</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>${lombok.version}</version><scope>provided</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><!-- 排除默认的logback日志，使用log4j--><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-logging</artifactId></exclusion><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions><version>${spring.boot.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-logging</artifactId></exclusion><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions><version>${spring.boot.version}</version></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${com.alibaba.cloud}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>

搭建类似这样的层次结构
