spring-data-r2dbc

问题 In Spring Data R2DBC I can log SQL queries by using logging.level.org.springframework.data.r2dbc=DEBUG in the application.properties . However, this doesn't log the actual values that are bound as query parameters. How can I log the actual values of query parameters in Spring Data R2DBC? 回答1: This worked for me : logging: level: io.r2dbc.postgresql.QUERY: DEBUG # for queries io.r2dbc.postgresql.PARAM: DEBUG # for parameters I found it here 回答2: If you happen to use MySQL, you can get a low

问题 I am trying my hands on spring-data-r2dbc. I am try this on Postgresql. I have tried spring-data-mongodb-reactive before. I couldn't help but to compare both. I see that Query Derivation is not yet supported. But I was wondering if there is an equivalent for @Tailable . This way I would be notified of the database changes in real time. Ca anyone share any code samples with respect to this. I understand that the underlying database should support this. I believe Postgresql does support this

问题 How does R2DBC implement transaction-handling. As far as I know, JDBC use one connection for one transaction. So in Spring MVC we have the following mapping: 1 request : 1 thread : 1 transaction : 1 connection. What is the mapping in Webflux with R2DBC? Webflux is reactive, so when we open one transaction, does it use one connection until the end of the transaction? If so, then a transaction is something like a blocking operation because, while the transaction is active no other transaction

问题 In my spring-boot 2.3 application, I have a simple data method using DatabaseClient : fun getCurrentTime(): Mono<LocalDateTime> = databaseClient .execute("SELECT NOW()") .asType<LocalDateTime>() .fetch() .first() } With spring-boot 2.4 (and spring 5.3 and spring-data-r2dbc 1.2), org.springframework.data.r2dbc.core.DatabaseClient from spring-data-r2dbc is deprecated in favor of org.springframework.r2dbc.core.DatabaseClient of spring-r2dbc - which has a different API. Adapting that is pretty

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
