什么时候支持dubbo3.0

warthur1214 commented 3 years ago

目前的2021.1版本不支持dubbo3.0，请问什么时候支持dubbo3.0

版本：

spring-cloud-starter-dubbo: 2021.1
dubbo: 3.0.0
dubbo-spring-boot-starter: 3.0.0
dubbo-spring-boot-actuator: 3.0.0

dubbo扫描org.mybatis.spring.mapper.MapperFactoryBean时getFactoryMethodMetadata报空指针了，感觉是和mybatis不兼容

    private boolean isAnnotatedReferenceBean(BeanDefinition beanDefinition) {
        if (beanDefinition instanceof AnnotatedBeanDefinition) {
            AnnotatedBeanDefinition annotatedBeanDefinition = (AnnotatedBeanDefinition) beanDefinition;
            String beanClassName = annotatedBeanDefinition.getFactoryMethodMetadata().getReturnTypeName();
            if (ReferenceBean.class.getName().equals(beanClassName)) {
                return true;
            }
        }
        return false;
    }

异常如下：

目前同 dubbo3 的集成工作正在进行中，会分成两批发布：

采用之前的方式适配 dubbo3 ，使用方法和集成方法上和 2.x 保持一致；
实现 dubbo3 与 sca + dubbo 的双向互调；其中第一部分，预期7月份能搞定，第二部分，要看参与的同学的精力，以及实现方案上有多少坑。

最后，dubbo 直接扫描 mybatis 好像本来就不太合理吧？是不是改下包路径呢？
