springcloud使用微服务的搭建

微服务的搭建

1.配置对应信息

• Springboot 、springcloud、springcloud alibaba对应关系

2.pom.xml的配置

2.1 总项目pom.xml引入依赖

    <parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.3.2.RELEASEversion>
        <relativePath/> 
        
    parent>

<properties>
    <java.version>1.8java.version>
    <spring-cloud.version>Hoxton.SR9spring-cloud.version>
    <spring-cloud-alibaba.version>2.2.6.RELEASEspring-cloud-alibaba.version>
properties>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-dependenciesartifactId>
            <version>${spring-cloud.version}version>
            <type>pomtype>
            <scope>importscope>
        dependency>

        <dependency>
            <groupId>com.alibaba.cloudgroupId>
            <artifactId>spring-cloud-alibaba-dependenciesartifactId>
            <version>${spring-cloud-alibaba.version}version>
            <type>pomtype>
            <scope>importscope>
        dependency>
    dependencies>
dependencyManagement>

2.2工具类模块引入(非必需)

  <dependencies>
      
        <dependency>
            <groupId>org.projectlombokgroupId>
            <artifactId>lombokartifactId>
        dependency>
        
        <dependency>
            <groupId>com.alibabagroupId>
            <artifactId>fastjsonartifactId>
            <version>1.2.79version>
        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

<dependency>
    <groupId>xxxxgroupId>
    <artifactId>ali-commonartifactId>
    <version>1.0.0version>
dependency>
<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-webartifactId>
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: 10022

spring:
  application:
    name: ali-user

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