spring bootカスタムstarter【エッセイ】

カスタムstarter
starter:
1、このシーンで使うべき依存は何ですか?
2、自動配置の編集方法

@Configuration  //           
@ConditionalOnXXX  //                  
@AutoConfigureAfter  //          
@Bean  //        

@ConfigurationPropertie    xxxProperties         
@EnableConfigurationProperties // xxxProperties        

         
              ，   META-INF/spring.factories
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
org.springframework.boot.autoconfigure.admin.SpringApplicationAdminJmxAutoConfiguration,\
org.springframework.boot.autoconfigure.aop.AopAutoConfiguration,\

3、モード:
ランチャーは依存導入のみに使用されます.
自動設定モジュールを専門に書きます.
ランチャー依存自動配置;他の人はスターターを導入するだけです.
