Spring find 2 candidates, but there is only one - spring

Question

I'm trying upgrade a JHipster project, however I found the following issue:
Description:
Parameter 0 of constructor in com.cervaki.config.AsyncConfiguration required a single bean, but 2 were found:
- jhipster-io.github.jhipster.config.JHipsterProperties: defined in null
- io.github.jhipster.config.JHipsterProperties: defined in null
Action:
Consider marking one of the beans as #Primary, updating the consumer to accept multiple beans, or using #Qualifier to identify the bean that should be consumed
What I understood is that spring can't inject the correct bean because there are two candidates, but I only have the io.github.jhipster.config.JHipsterProperties implementation:
package com.cervaki.config;
import io.github.jhipster.async.ExceptionHandlingAsyncTaskExecutor;
import io.github.jhipster.config.JHipsterProperties;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.aop.interceptor.SimpleAsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.*;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.Executor;
#Configuration
#EnableAsync
#EnableScheduling
public class AsyncConfiguration implements AsyncConfigurer {
private final Logger log = LoggerFactory.getLogger(AsyncConfiguration.class);
private final JHipsterProperties jHipsterProperties;
public AsyncConfiguration(JHipsterProperties jHipsterProperties) {
this.jHipsterProperties = jHipsterProperties;
}
#Override
#Bean(name = "taskExecutor")
public Executor getAsyncExecutor() {
log.debug("Creating Async Task Executor");
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(jHipsterProperties.getAsync().getCorePoolSize());
executor.setMaxPoolSize(jHipsterProperties.getAsync().getMaxPoolSize());
executor.setQueueCapacity(jHipsterProperties.getAsync().getQueueCapacity());
executor.setThreadNamePrefix("cervaki-Executor-");
return new ExceptionHandlingAsyncTaskExecutor(executor);
}
#Override
public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
return new SimpleAsyncUncaughtExceptionHandler();
}
}
You can download the pom.xml here.
I did a search in the entire code and libs to find the jhipster-io.github.jhipster.config.JHipsterProperties file, however I didn't find anything.
What can I do to solve this problem?

Answer 1

I also faced this issue after generating new JhipsterApp,
And as you - I don't find the "jhipster-io" dependencies in project
How I solve this:
in src/main/java/your/package/config create a "AppConfiguration.java"
with content:
import io.github.jhipster.config.JHipsterProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
#Configuration
public class AppConfiguration {
#Bean
#Primary
public JHipsterProperties jHipsterProperties() {
return new JHipsterProperties();
}
}
even without #Primary - I haven't got this error
