Micronaut

问题 I'm new in Micronaut framework and I'm trying to use entitymanager to create my repository. I created my repository like this public interface EmployeeRepository { Employee save(@NotNull Employee employee); Employee update(@NotNull Employee employee); List<Employee> findAll(); Optional<Employee> findById(@NotNull Long id); } and I used this class to implement the interface and to inject entitymanager @Singleton public class EmployeeRepositoryImpl implements EmployeeRepository{

问题 I'm trying to get micronaut (1.2.6) to use my code to instantiate a JacksonConfiguration instead of the default mechanism.

问题 I am using Micronaut framework for a project and Micronaut CLI generates project with com.github.johnrengelman.shadow gradle plugin which works fine when I run the jar using- $ java -Dmicronaut.environments=E1 -jar build/appBundle/app.jar build.gradle - plugins { id "com.github.johnrengelman.shadow" version "5.0.0" } ... shadowJar { mergeServiceFiles() } The issue is that com.github.johnrengelman.shadow plugin is not working with Jenkins for some reason and I am suspecting that it's not

问题 Defining an @Singleton bean in Micronaut does not @Inject the same instance into Picocli commands. Micronaut offers an integration with Picocli. What is essential done, it seems, is that from the Picocli command, one can start an EmbeddedServer of Micronaut (maybe the problem is already here that Micronaut is started only really started from within Picocli?). When I define a class as singleton via @Singleton, and @Inject it both in a Rest-endpoint of Micronaut and the Picocli command, it

问题 We have been evaluating the Micronaut framework and are looking to use the Apache Camel library. I do not see a specific integration with Apache Camel. The Apache Camel library does support a set of annotations. Questions Can we use Apache Camel with Micronaut? If we attempt to use Apache Camel annotations, will it work but revert to using the Java annotation api, i.e. work but not be optimized for Micronaut? 回答1: Can we use Apache Camel with Micronaut? Yes. If we attempt to use Apache Camel

问题 I am migrating a tiny Spring Boot application to Micronaut 1.0.1 and I was wondering if there is an equivalent for org.springframework.core.io.Resource and their implementation such as ClasspathResource ? In Spring Boot I inject a resource into a service using its constructor. @Service public class MyService() { private final Resource resource; public MyService(Resource resource) { this.resource = resource; } } How can I do this in Micronaut? @Singleton public class MyService() { private

问题 I would like to configure logging appender based on the environment , for example while running in production I would like to configure an appender that would send log to elasticsearch but while on test or development mode this appender would not be enabled. 回答1: To put the correct answer here from the above comment. According to this link, you can just add a logback-production.xml , where production is the name of your profile. 回答2: As far I understand, Micronaut doesn't have similar thing
