Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. Use a mn bean in a grails service that has 2 qualifying beans (in this case lettuce)

Expected Behaviour

The bean marked as Primary should be used.

Actual Behaviour

***************************
APPLICATION FAILED TO START
***************************

Description:

Field statefulRedisConnection in grails.ExampleService required a single bean, but 2 were found:
	- io.lettuce.core.api.StatefulRedisConnection(Primary): defined in null
	- io.lettuce.core.pubsub.StatefulRedisPubSubConnection($DefaultRedisClientFactory$RedisPubSubConnectionDefinition): 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

Work around

Add qualifier

@Qualifier("io.lettuce.core.api.StatefulRedisConnection(Primary)")

Environment Information

• Operating System: macOs 10.14.5
• Grails Version: 4.0.0
• JDK Version: 11.0.2
• Container Version (If Applicable): n/a

Example Application

@jameskleeh : I upgraded the example project (erichelgeson/mnbeansPrimary@0a35af5) to Grails 4.0.1 (andersaaberg/mnbeansPrimary@3396fa6), but it still fails on startup with the error:
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'io.lettuce.core.api.StatefulRedisConnection<?, ?>' available: expected single matching bean but found 2: io.lettuce.core.pubsub.StatefulRedisPubSubConnection($DefaultRedisClientFactory$RedisPubSubConnectionDefinition),io.lettuce.core.api.StatefulRedisConnection(Primary)

@andersaaberg I have added tests for this in grails3-functional-tests. Ensure you have micronaut-spring:1.0.2 on your classpath

[andersaaberg]

@jameskleeh I have extended your test with injection of an actual StatefulRedisConnection bean: https://github.com/grails/grails3-functional-tests/pull/22

The test only passes when using the qualifier as workaround: @Qualifier("io.lettuce.core.api.StatefulRedisConnection(Primary)")

Am I doing something wrong?

[jameskleeh]

@andersaaberg Hard to say. You can debug https://github.com/micronaut-projects/micronaut-spring/blob/a4f1bd7618ec4c8d1c298777adf881fa0ef65120/spring-context/src/main/java/io/micronaut/spring/context/factory/MicronautBeanFactory.java#L804 to see if the bean is getting correctly identified as primary
