微服务的搭建

1.配置对应信息

• Springboot 、springcloud、springcloud alibaba对应关系

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 总项目pom.xml引入依赖

    <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工具类模块引入(非必需)

  <dependencies><!-- lombok类 --><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创建微服务

步骤:

• 创建maven模块并导入依赖(ali-user)

• 添加springboot的启动类

• 入配置文件application.yml

• 创建必要的接口和实现类(controller service dao)

1 .创建(ali-user)maven模块或springboot模块并导入依赖

<!--工具类引入-->
<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的启动类

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 .创建必要的接口和实现类(controller service dao)
