Java-buildpack: O JBP suporta Spring Boot 2.0?

Ainda não testamos contra ele, mas considerando que a forma como ele funciona ( java -jar ) não mudou, não tenho nenhuma razão para acreditar que não.

Na verdade, tenho um problema com o M3 atual. Mas isso só acontece quando o MongoDB é usado. O Cloud Foundry tenta reconfigurar a conexão MongoDB e executa um NoSuchMethodError .

Pelo que posso ver, isso se deve a alterações significativas na dependência spring-data-mongo .

A configuração é um aplicativo Spring Boot 2.0.0.M3 básico com iniciadores para:

• atuador do
• data-mongo
• rede
• etc.

Sim, este é um problema de reconfiguração automática. Dependemos de uma versão do Spring Cloud Connectors que pode não estar pronta para o upgrade da versão principal para o Spring Data. @scottfrederick você está ciente disso e tudo o que precisarei fazer é começar a usar uma nova versão dos conectores Spring Cloud?

Estou atualizando nossos aplicativos de teste Java para Boot 2.0 . Com base nesse trabalho, a única coisa que parece ter um problema é que a reconfiguração automática do Spring Data Mongo parece estar quebrada (alterações de API). Vou deixar esse problema aberto como um indicador disso e, em seguida, fechá-lo quando tivermos uma solução.

Alguma estimativa de quando isso estará disponível? Além disso: existem soluções alternativas aplicáveis ​​no momento?

Estamos muito perto de entregar, mas ainda estamos esperando por @scottfrederick para lançar o Spring Cloud Connectors. Fizemos um trabalho significativo para simplificar a reconfiguração automática e atualizá-la para usar Spring Cloud Connectors 2.x. Como parte desse trabalho, enviamos um PR para garantir que todos os tipos configurados fossem compatíveis no Boot 1.xe no Boot 2.x. Isso foi incluído, mas ainda está em teste. Assim que for lançado, iremos consumi-lo e obter uma nova versão da reconfiguração automática.

Não há necessidade real de uma solução alternativa, pois tudo, exceto a reconfiguração automática do MongoDB, funciona como esperado hoje. Se você está tentando fazer a reconfiguração automática do MongoDB, não há outra alternativa além de configurar explicitamente seu aplicativo para usar o serviço (o que você deveria fazer de qualquer maneira; a reconfiguração automática não é uma boa escolha para sistemas de produção).
