Idea 2023.2.7构建SpringCloud多模块项目
本文介绍如何使用idea 2023.2.7构建基于SpringCloud alibaba微服务项目，基于Nacos注册中心。
环境准备：
JDK版本：jdk17
SpringBoot:3.3.4
SpringCloud:2023.0.3
Nacos服务端:2.4.3
1、创建父工程，选择Spring Initalizr
2、选择父项目组件
3、删除src
4、修改父模块pom.xml配置文件
默认的打包方式是jar，父工程不参与打包，增加
<packaging>pom</packaging>
并引入alibaba依赖整合
<!--整合springcloud alibaba-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>2021.0.5.0</version><type>pom</type><scope>import</scope>
</dependency>
引入公共依赖如orm框架、注册中心、数据库连接池等
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><scope>runtime</scope>
</dependency>
<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional>
</dependency>
<dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>3.0.5</version>
</dependency>
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>2023.0.1.2</version>
</dependency>
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-loadbalancer</artifactId>
</dependency>
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId><version>4.1.4</version>
</dependency>
<!--引入sentinel依赖-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId><version>2023.0.1.2</version>
</dependency>
5、创建子模块user-center
(1)选中项目，右击，New->Module
(2)输入Name:user-center用户中心信息
（3）选择需要的组件，父工程中已包含依赖可不选
（4）创建完成，结构如下
（5）修改user-center的pom.xml文件，修改parent里的groupId为父工程groupId
修改前：
修改后：
<parent><groupId>com.xu</groupId><artifactId>psyRestRoom</artifactId><version>0.0.1-SNAPSHOT</version><relativePath/> <!-- lookup parent from repository -->
</parent>
（6）修改父工程pom.xml，加modules
<modules><module>user-center</module>
</modules>
（7）application.yml配置
spring:application:name: user-centerdatasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: ENC(w1Teu1o/5A3viCdkQ3VkC6++hMwBrsGip37LnjTi0h0Xqa3MoQ3ilOxSbg9otQTuoTm/Z3bTPPFqsBlYFo+6aiNdyOe25oON5AqF0mycFxMreo3VVrkn8ZkpXETkUBYt)username: ENC(jSszHsa26QY5M/aI7aM6pNtQGcyEnPU0NJIHG5C4oN5uu00PGgkyh+Up/gHIIlah)password: ENC(VhlpQvPt9FUqy4sbpweQ5Q5PQ/mspFmOUV+RdjI4VGfekp/gK/2swL6b5cgnPWDa)cloud:nacos:discovery:server-addr: http://192.168.1.226:8848username: nacospassword: nacosconfig:import-check:enabled: falsefile-extension: ymlsentinel:transport:dashboard: localhost:8080 #配置sentinel服务端http-method-specify: true #开启请求方式前缀
nacos:core:auth:enabled:true
jasypt:encryptor:password: f0d15ddc
server:port: 8081
feign:sentinel:enabled: true（8）增加bootstrap.yaml
spring:cloud:nacos:config:server-addr: http://192.168.1.226:8848name: user-centerfile-extension: yamlgroup: DEFAULT_GROUPusername: nacospassword: nacos
再根据以上方法创建子模块
启动子模块如下：
