    Enterprise Distributed Application Service:Error code: HSF-0008

    Last Updated:Mar 11, 2026

    Error message

    java.lang.IllegalArgumentException: The service type specified in ProviderBean does not indicate the [com.taobao.hsf.jar.test.HelloWorldServiceImpl] interface.

    Cause

    The serviceInterface property in your HSF ProviderBean configuration references a concrete implementation class instead of a Java interface.

    HSF requires serviceInterface to be an interface type. When it references a class such as com.taobao.hsf.jar.test.HelloWorldServiceImpl, HSF throws an IllegalArgumentException.

    Solution

    In your HSF bean configuration file, change the serviceInterface value from the implementation class to the corresponding Java interface.
