环境： jdk17

idea 2019

springboot:3.2.4

spring-cloud:2023.0.1

大概记录下关键配置

1 创建父工程

创建项目

删除src目录

因为是父子结构不需要。

引入依赖

2 创建子模块（服务提供者）

新建module

引入依赖

<?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>spring-cloud-alibaba-demo</artifactId><groupId>org.tuling</groupId><version>1.0.0</version></parent><modelVersion>4.0.0</modelVersion><artifactId>order01</artifactId><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!-- Nacos注册中心 --><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency><!-- lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><!-- <version>8.0.32</version> --></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>3.0.3</version></dependency></dependencies><build><plugins><!-- 打包插件 --><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin></plugins><!-- 将源码中的xml文件打包到jar中 --><resources><resource><directory>src/main/java</directory><excludes><exclude>**/*.java</exclude></excludes></resource><resource><directory>src/main/resources</directory><includes><include>**/*.*</include></includes></resource></resources></build></project>

3 添加配置文件

resources目录下新建 application.yml 配置文件，内容如下：

server:port: 8060spring:application:name: tlmall-order01cloud:nacos:discovery:server-addr: tlmall-nacos-server:8848#server-addr: nacos.tlmall.com:8848#namespace: fox  #指定为fox开发环境的命名空间#namespace: dev  # 指定注册到开发环境#cluster-name: SH  #上海机房username: nacospassword: nacosdatasource:url: jdbc:mysql://XXX:3306/tlmall_order?useSSL=false&characterEncoding=utf8&allowPublicKeyRetrieval=truedriver-class-name: com.mysql.cj.jdbc.Driverusername: rootpassword: 1234XXXXXmain:allow-bean-definition-overriding: true
mybatis:# 配置 mybatis 的xml文件的扫描路径mapper-locations: classpath:mybatis/**/*.xml# 配置实体类的扫描路径type-aliases-package: org.tuling.tlmallorder01.entityconfiguration:# 开启驼峰命名转换map-underscore-to-camel-case: true# 开启日志#log-impl: org.apache.ibatis.logging.stdout.StdOutImpllog-impl: org.apache.ibatis.logging.slf4j.Slf4jImplmanagement:endpoints:web:exposure:include: "*"

配置注意：数据源 

4 添加启动类

5 添加测试业务代码

controller

service

mapper

/resources/mybatis/ 目录下新增 XXMapper.xml 文件

 

CREATE TABLE `order` (`id` bigint unsigned NOT NULL AUTO_INCREMENT,`user_id` varchar(255) DEFAULT NULL,`commodity_code` varchar(255) DEFAULT NULL,`count` int DEFAULT NULL,`money` int DEFAULT '0',`create_time` datetime DEFAULT NULL,`update_time` datetime DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=90 DEFAULT CHARSET=utf8mb3;

6 服务的测试

启动nacos.参见：nacos 让服务之间互相认识-CSDN博客

启动应用，测试接口

如果启动了nacos.观察下服务列表

注意下EndPoint，http://localhost:8060/actuator/nacosdiscovery

至此，springBoot的项目基本架构搭建成功。可以陆续添加其它子模块。主要是pom里面的配置，版本不一致可能产生的问题。
