Code generation does not support ApplicationContext

[CrazyHZM]

Repeat step:

        AbstractBeanDefinition beanDefinition = builder.getBeanDefinition();
        beanDefinition.setAutowireMode(AbstractBeanDefinition.AUTOWIRE_CONSTRUCTOR);
        ConstructorArgumentValues constructorArgumentValues = new ConstructorArgumentValues();
        constructorArgumentValues.addIndexedArgumentValue(0,applicationContext);
        beanDefinition.setConstructorArgumentValues(constructorArgumentValues);

Affects: 6.0.11

@CrazyHZM thanks for the report but you don't need to add a constructor argument value if you're using autowiring. Autowiring should inject the context just fine. Can you please try that?

@snicoll
My Bean does not have a parameterless constructor. After removing the constructor argument value, exceptions without parameterless constructors will be thrown. I think aot does not look for constructors based on the autowiring method.

My Bean does not have a parameterless constructor.

Yes, it looks like it takes an ApplicationContext. We can't easily write the code that represents an ApplicationContext for obvious reasons.

I think aot does not look for constructors based on the autowiring method.

I think it does for the simple reason it should be the same code as regular runtime with a number of limitations that seems unrelated. Unfortunately, some partial code in text does not make a valid reproducer. If you want support, please take the time to attach a small sample we can run ourselves that reproduces the issue you've described. Thanks.

@snicoll
Thanks for reply, here's an example:
https://github.com/apache/dubbo-samples/tree/master/1-basic/dubbo-samples-native-image/dubbo-samples-native-image-provider
You can reproduce the problem by running mvn clean install -P native native:compile -D maven.test.skip=true

The ServiceBean is defined here: https://github.com/apache/dubbo/blob/3.2/dubbo-config/dubbo-config-spring/src/main/java/org/apache/dubbo/config/spring/ServiceBean.java

[snicoll]

Both those links lead to a 404The first link leads to a 404. Please make sure that the sample is as minimal as possible. I shouldn't have to deal with dubbo to reproduce the problem you've described.
