Subject [jira] [Commented] (CXF-6694) SpringResourceFactory does not work with constructor-autowired beans
Date Tue, 01 Dec 2015 10:30:10 GMT


Sergey Beryozkin commented on CXF-6694:

This is related to this JAX-RS spec text: "Provider classes that are instantiated by the JAX-RS
runtime and MUST have a public constructor for which the JAX-RS runtime *can provide all parameter
values*. Note that a zero argument constructor is permissible under this rule.". But perhaps
that can be relaxed for singletons instantiated by Spring if a non-default constructor has
no @Context parameters

> When used with constructor-autowired bean, it fails with "Resource class ... has no valid
constructor" exception. We don't need constructor at all when we already have a singleton
instance from Spring.
> Also it looks like {{isSingleton()}} is called for the first time before correct value
is calculated a few lines below: {{isSingleton = ac.isSingleton(beanId)}}
