Descriptions
TestProvider has two implementation classes, TestServiceImpl and TestServiceExtImpl. I want to use @ConditionalOnMissingBean to load TestServiceImpl if the bean does not exist. How can I do this?
`
public interface TestProvider { String getName(); }
@ConditionalOnMissingBean(TestProvider.class) @DubboService(interfaceClass = TestProvider.class) public class TestServiceImpl implements TestService { @Override public String getName() { return "getName:TestServiceImpl:"; } }
@DubboService(interfaceClass = TestProvider.class) public class TestServiceExtImpl extends TestServiceImpl{ @Override public String getName() { return "TestServiceExtImpl:"; } } `
