微服務的搭建

1.配置對應信息

• Springboot 、springcloud、springcloud alibaba對應關系

https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E

2.pom.xml的配置

2.1 總項目pom.xml引入依賴

    <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.2.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><java.version>1.8</java.version><spring-cloud.version>Hoxton.SR9</spring-cloud.version><spring-cloud-alibaba.version>2.2.6.RELEASE</spring-cloud-alibaba.version>
</properties><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring-cloud-alibaba.version}</version><type>pom</type><scope>import</scope></dependency></dependencies>
</dependencyManagement>

2.2工具類模塊引入(非必需)

  <dependencies><!-- lombok類 --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><!-- 阿里JSON解析器 --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.79</version></dependency></dependencies>

2.3創建微服務

步驟:

• 創建maven模塊并導入依賴(ali-user)

• 添加springboot的啟動類

• 入配置文件application.yml

• 創建必要的接口和實現類(controller service dao)

1 .創建(ali-user)maven模塊或springboot模塊并導入依賴

<!--工具類引入-->
<dependency><groupId>xxxx</groupId><artifactId>ali-common</artifactId><version>1.0.0</version>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>

2 添加springboot的啟動類

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class UserApplication {public static void main(String[] args) {SpringApplication.run(UserApplication.class);}
}     

3 .加入配置文件application.yml

server:port: 10022spring:application:name: ali-user

4 .創建必要的接口和實現類(controller service dao)
