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>

    </dependencies>

</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"

    </parent>
    <modelVersion>4.0.0</modelVersion>

        </dependency>

        </dependency>
    </dependencies>


</project>

（5）数据访问模块搭建

 

<?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">

        </dependency>

    </dependencies>


</project>

 

接下来就是在service-api模块搭建实际的业务代码了，略
