1、数据库表结构设计
2、项目结构设计搭建
（1）创建父工程（SpringBoot 类型）
创建版本是JDK 1.8
填写项目信息
在pom文件中添加
代码如下：
<packaging>pom</packaging>
<swagger.version>2.9.2</swagger.version>
<fastjson.version>1.2.51</fastjson.version> <dependencyManagement>
<dependencies>
<!-- springCloud -->
<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>

</project>
在父工程中引入了SpringCloud等很多以后需要用到的依赖，以后创建的子工程就不需要自己引入了。
删除以上四个文件
（2）其他功能模块搭建
创建 Maven 项目，注意版本号的选择
添加这句话
<packaging>pom</packaging> 
删除 src 文件夹
其他模块重复操作，创建qixing-service,qixing-service-api,qixing-web工程。注意pom文件需要修改打包方式
（3）创建 eureka
eureka的pom文件代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>qixing-parent</artifactId>
<groupId>com.demo</groupId>
<version>1.0</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>qixing-eureka</artifactId>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies>
</project>在eureka模块中的 resources中建立 application.yml
server:
port: 8761
spring:
application:
name: qixing-eureka
eureka:
instance:
hostname: 127.0.0.1
client:
register-with-eureka: false #是否将自己注册到eureka中
fetch-registry: false #是否从eureka中获取信息
service-url:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka
server:
enable-self-preservation: false # 关闭自我保护
eviction-interval-timer-in-ms: 5000 # 每隔5秒进行一次服务列表清理在eureka中创建如下目录及文件
代码如下：
package com.qixing;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
/**
* @Author caojun
* @Date 2023/4/20 14:55
* @Description :caojun java
*/
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class,args);
}
}
启动可以看到 eureka 主页，访问 http://localhost:8761/
（4）创建common 模块
在common模块中的pom文件代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
