I'm writing a Confluence plugin and I need to get user full name given user ID. I found `UserAccessor` interface, but whenever I try to use it in my components I get `NoSuchBeanDefinitionException`:
```
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.atlassian.confluence.user.UserAccessor' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
```
I saw similar question raised before, but I couldn't find any clear resolution. Should I be using some other bean to get user details from?
