一、主要流程

1. 先创建空的project

2. 打开空的project 结构 图选中model 点击+

3. 创建 model（Maven）启动器

提醒：创建启动器 model在旧版本intelliJ IDEA 左边有 Maven 选项，应该选择 Maven，新版本里没有了，所以选择Spring initializr， 等创建完手动修改pom.xml文件

4.创建自动配置model

二、mystarter-spring-boot-starter模块里的pom.xml文件配置信息

<?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"><modelVersion>4.0.0</modelVersion><groupId>org.example.mystarter</groupId><artifactId>mystarter-spring-boot-starter</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>20</maven.compiler.source><maven.compiler.target>20</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><!--    启动器--><dependencies>
<!--        引入自动配置--><dependency><groupId>com.example.mystarter</groupId><artifactId>mystarter-spring-boot-starter-autoconfigurer</artifactId><version>0.0.1-SNAPSHOT</version></dependency></dependencies></project>

三、mystarter-spring-boot-starter-autoconfigurer模块里的pom.xml文件配置信息

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.1.1</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example.mystarter</groupId><artifactId>mystarter-spring-boot-starter-autoconfigurer</artifactId><version>0.0.1-SNAPSHOT</version><name>mystarter-spring-boot-starter-autoconfigurer</name><description>mystarter-spring-boot-starter-autoconfigurer</description><properties><java.version>17</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><!--		https://docs.spring.io/spring-boot/docs/3.1.1/reference/html/configuration-metadata.html#appendix.configuration-metadata.annotation-processorhttps://blog.csdn.net/Zhangsama1/article/details/129198456使用spring-boot-configuration-processor，作用就是将自己的配置自己创建的配置类生成元数据信息，这样就能在自己的配置文件中显示出来非常的方便例如：在application.yml中自定义配置信息，使用开发工具做自定义信息提示
--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency></dependencies></project>

四、LearnSpringBoot08starter工程结构图

五、mystarter-spring-boot-starter-autoconfigurer核心代码

HelloProperties.java代码

package com.example.mystarter;import org.springframework.boot.context.properties.ConfigurationProperties;@SuppressWarnings("ConfigurationProperties")
@ConfigurationProperties(prefix = "test.hello")
public class HelloProperties {private String prefix;private String suffix;public String getPrefix() {return prefix;}public void setPrefix(String prefix) {this.prefix = prefix;}public String getSuffix() {return suffix;}public void setSuffix(String suffix) {this.suffix = suffix;}
}

HelloService.java代码

package com.example.mystarter;public class HelloService {HelloProperties helloProperties;public String sayHello(String name){return helloProperties.getPrefix() + "-" + name + helloProperties.getSuffix();}public HelloProperties getHelloProperties() {return helloProperties;}public void setHelloProperties(HelloProperties helloProperties) {this.helloProperties = helloProperties;}
}

HelloServiceAutoConfiguration.java代码

package com.example.mystarter;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnWebApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*
https://blog.csdn.net/Zhangsama1/article/details/129198456
在SpringBoot2.7.x版本之后，慢慢不支持META-INF/spring.factories文件了，需要导入的自动配置类可以放在/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports文件中*/
@Configuration
@ConditionalOnWebApplication// 在web应用上生效
@EnableConfigurationProperties(HelloProperties.class)
public class HelloServiceAutoConfiguration {@AutowiredHelloProperties helloProperties;@Beanpublic HelloService helloService(){HelloService helloService = new HelloService();helloService.setHelloProperties(helloProperties);return helloService;}
}

org.springframework.boot.autoconfigure.AutoConfiguration.imports代码

com.example.mystarter.HelloServiceAutoConfiguration

六、将自动配置model和启动器model安装到Maven仓库

7、创建新的工程测试自定义starter

LearnSpringBoot08starterTest工程结构图

pom.xml代码

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.1.1</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example</groupId><artifactId>LearnSpringBoot08starterTest</artifactId><version>0.0.1-SNAPSHOT</version><name>LearnSpringBoot08starterTest</name><description>LearnSpringBoot08starterTest</description><properties><java.version>17</java.version></properties><dependencies><!--	引入自定义的启动器	--><dependency><groupId>org.example.mystarter</groupId><artifactId>mystarter-spring-boot-starter</artifactId><version>1.0-SNAPSHOT</version></dependency><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><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

HelloController.java代码

package com.example.learnspringboot08startertest.controller;import com.example.mystarter.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class HelloController {@AutowiredHelloService helloService;@GetMapping("/hello")public String hell(){return helloService.sayHello("test01");}
}

application.properties

server.port=8086
test.hello.prefix=CUSTOM STARTER
test.hello.suffix=HELLO WORD

八、测试结果

启动LearnSpringBoot08starterTest工程，在浏览器地址栏访问：http://localhost:8086/hello
