问题 I Want to write one new application with Spring boot using the database as MySQL + Mango and for messaging Spring Kafka. I tried with Many POC for synchronizing the transaction between Kafka and DB but I failed in certain conditions and also I searched many Repositories, blogs to get at least one example. I didn't get any example still now. if anyone gives at least one example or configurations it would be a nice reference in the future for all. 回答1: Here you go... @SpringBootApplication

问题 I was playing with org.springframework.data.jpa.domain.Specifications, it's just a basic search : public Optional<List<Article>> rechercheArticle(String code, String libelle) { List<Article> result = null; if(StringUtils.isNotEmpty(code) && StringUtils.isNotEmpty(libelle)){ result = articleRepository.findAll(Specifications.where(ArticleSpecifications.egaliteCode(code)).and(ArticleSpecifications.egaliteLibelle(libelle))); }else{ if(StringUtils.isNotEmpty(code)){ result= articleRepository

问题 I have an application which is using Spring data JPA and hibernate envers for db auditing. Since R2DBC doesn't support auditing yet, is it possible to use combination of both in a single application? If yes, Plan is to use Spring Data JPA for insert, update and delete operations, so that all DB auditing will be handled by hibernate envers. And use R2DBC for reactive non-blocking API's to read data. If no, Is there any suggestions on how to achieve both reactive API's and auditing? 回答1: Spring
