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

复制代码

<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>

复制代码

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>

    <scope>runtime</scope>

    <artifactId>lombok</artifactId>
    <optional>true</optional>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
    <version>4.1.4</version>

<!--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：

复制代码

<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

复制代码

<modules>
    <module>user-center</module>
</modules>

（7）application.yml配置

复制代码

spring:
  application:
   name: user-center
  datasource:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: 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://192.168.1.226:8848
          username: nacos
          password: nacos
        config:
          import-check:
            enabled: false
          file-extension: yml
      sentinel:
        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

复制代码

spring:
  cloud:
    nacos:
      config:
        server-addr: http://192.168.1.226:8848
        name: user-center
        file-extension: yaml
        group: DEFAULT_GROUP
        username: nacos
        password: nacos

再根据以上方法创建子模块

启动子模块如下：
