问题 I'm bothering with situation when I want to emit query update via queryUpdateEmitter but in different module (microservice). I have application built upon microservices and both are connected to the same Axon Server. First service creates subscriptionQuery, and sends some commands. After a while (through few commands and events) second service handles some event, and emits update for firstly subscribed query. Unfortunately it seems like this emit doesn't get to subscriber. Queries are exactly

问题 I am using Spring Boot 2 with spring-boot-starter-data-jpa with an underlying MariaDB. I have table with a unique key "username". I want to catch DataIntegrityViolationException if this constraint is violated, but it seems like Spring is logging DataIntegrityViolationException and does not rethrow the after logging(my best guess). MySQLIntegrityConstraintViolationException is thrown instead. I would like to catch DataIntegrityViolationException in UserService.createUser(..) . Here are a

问题 Is there a Spring Boot Actuator Health Check endpoint for SQS? I have built a SQS consumer and I want to check if SQS is up and running. I am not using JMSlistener for connecting to SQS but rather using Spring Cloud Libraries. I implemented the below health check endpoint. This returns the below error when I delete the queue and try to hit the health check endpoint. If there is a connectivity issue or if the SQS service goes down , will I be getting a similar error which will eventually cause

问题 I coded a very simple and common CRUD in Kotlin. I want to do basic tests as testing post, delete, get and put. Probably I understood something wrong: I used Beforeeach aimed to insert a register so I could check during get test. I don't get exception but it seems during get test it always returning ok when it should be NOT_FOUND for any other id different than 1 in bellow test. Any clue or guidance in right direction will be wellcome even if see other bad practice bellow based on my purpose

问题 I'm very new to Spring. I'm trying to create a REST API using Spring Boot and I'm stuck whether to expose my user's primary key or not which also happens to be their email. Something like api/user/example@gmail.com . A big part of me says it's okay since it would sensible to expose it as it is the identifier for that specific record when viewing, deleting, and updating. Is there a security risk for this? What is the best practice for such implementation? Right now I'm combining the
