大致结构

org.springframework.boot.autoconfigure.AutoConfiguration.imports

如果是SpringBoot2.7之前

在META-INF下新建spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.yiyi.registerspringbootstarter.config.RegisterAutoConfiguration

package com.yiyi.registerspringbootstarter.config;import com.yiyi.registerspringbootstarter.service.RegisterService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
@EnableConfigurationProperties(RegisterProperties.class)
public class RegisterAutoConfiguration {@Autowiredprivate  RegisterProperties registerProperties;@Bean@ConditionalOnMissingBean(RegisterService.class)public RegisterService createRegisterConfiguration(){return  new RegisterService(registerProperties.getUsername(),registerProperties.getPassword(),registerProperties.getTelephone());}}

package com.yiyi.registerspringbootstarter.config;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;@ConfigurationProperties(prefix = "register.user")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class RegisterProperties {private String username="admin";private String password="123456";private String telephone;}

package com.yiyi.registerspringbootstarter.service;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@NoArgsConstructor
@AllArgsConstructor
public class RegisterService {private String username;private String password;private String telephone;public void register(){System.out.println("注册成功！你的注册信息如下：");System.out.println("用户名："+username);System.out.println("密码："+password);System.out.println("电话："+telephone);}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String getTelephone() {return telephone;}public void setTelephone(String telephone) {this.telephone = telephone;}}

install打包到本地仓库  其他项目可以引入了

在配置文件中

register.user.username=xxxx

register.user.password=xxxx

register.user.telephone=xxxx

不配置就是默认值

不引入web也可以  这个就够了
