这篇文章给大家介绍spring cloud 中怎么搭建alibaba微服务，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
1.创建父工程cloud2020
2.引入相关jar包
<modelVersion>4.0.0</modelVersion><groupId>com.yxw.springcloud</groupId><artifactId>cloud2020</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><modules> <module>cloud-provider-payment8001</module></modules><name>springcloud</name><!-- FIXME change it to the project's website --><url>http://maven.apache.org/</url><inceptionYear>2001</inceptionYear><distributionManagement> <site> <id>website</id> <url>scp://webhost.company.com/www/website</url> </site></distributionManagement><!--统一管理jar包版本--><properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <junit.version>4.12</junit.version> <log4j.version>1.2.17</log4j.version> <lombok.version>1.16.18</lombok.version> <mysql.version>8.0.24</mysql.version> <druid.version>1.1.16</druid.version> <mybatis.spring.boot.version>1.3.0</mybatis.spring.boot.version></properties><!--子模块继承之后，提供作用：锁定版本+子module不用groupId和version--><dependencyManagement> <dependencies> <!--spring boot 2.2.2--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.2.2.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <!--spring cloud Hoxton.SR1--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Hoxton.SR1</version> <type>pom</type> <scope>import</scope> </dependency> <!--spring cloud alibaba 2.1.0.RELEASE--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.1.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>${lombok.version}</version> <optional>true</optional> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <exclusions> <exclusion> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> </exclusion> </exclusions> </dependency> </dependencies></dependencyManagement><build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.1.6.RELEASE</version> <configuration> <fork>true</fork> <addResources>true</addResources> </configuration> </plugin> </plugins></build>
3.创建子工程
cloud-provider-payment8001
4.引入相关jar包
<parent> <artifactId>cloud2020</artifactId> <groupId>com.yxw.springcloud</groupId> <version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>cloud-provider-payment8001</artifactId><dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency> <!--mysql-connector-java--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <!-- 热部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.4.0</version> </dependency> <!-- 代码生成器 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.4.0</version> </dependency> <!-- 模板引擎 --> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-engine-core</artifactId> <version>2.0</version> </dependency> <dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-site-plugin</artifactId> <version>3.3</version> </dependency></dependencies>
5.创建启动类
@SpringBootApplication@MapperScan(basePackages = "com.yxw.**.mapper")public class PaymentApplication {public static void main(String[] args) {
SpringApplication.run(PaymentApplication.class, args); }
}
6.编写yml文件
server: port: 8001spring: application:name: cloud-provider-service datasource:type: com.alibaba.druid.pool.DruidDataSource #当前数据源操作类型 driver-class-name: com.mysql.cj.jdbc.Driver #mysql驱动包 url: jdbc:mysql://localhost:3306/cloud2020?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowPublicKeyRetrieval=trueusername: rootpassword: 123456mybatis-plus: #实体扫描，多个package用逗号或者分号分隔 typeAliasesPackage: com.yxw.**.model mapper-locations: classpath:mapper/*.xml
7.编写业务代码测试我们之前搭建的环境是否可用，代码这里就不贴出来了，获取完整代码：https://gitee.com/xiaowei_328/cloud2020.git
8.在创建个子工程：cloud-consumer-order80
注：相关配置和代码这里可以参考我上传的代码这里不做过多解释
9.用RestTemplate调用我们8001端口服务
10.controller代码如下：
配置好以后分别启动80和8001端口的服务
浏览器访问如下：http://localhost/consumer/payment/get/1388397492484583426
简单说明下因为我访问的时候没有加80端口，因为浏览器默认就是80端口所以这里可以省略。
工程重构
1.上面我们创建的80和8001两个服务都有共同的实体类，我们要给抽出来一个公共的模块
（1）接着在父工程下创建子工程：cloud-api-commons
(2)修改pom文件
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <version>5.1.0</version> </dependency></dependencies>
（3）将我们之前创建的实体类复制到commons工程下
2.修改cloud-consumer-order80工程pom文件，引入cloud-api-commons公共服务jar包
<!--引入自己定义的api通用包，可以使用Payment支付Entity--><dependency> <groupId>com.yxw.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version></dependency>
3.修改cloud-provider-payment8001工程pom文件，引入cloud-api-commons公共服务jar包
<!--引入自己定义的api通用包，可以使用Payment支付Entity--><dependency> <groupId>com.yxw.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version></dependency>
