This article mainly introduces "what is the Dubbo bean method of Mock injection". In the daily operation, I believe that many people have doubts about what the Dubbo bean method of Mock injection is. The editor consulted all kinds of data and sorted out a simple and easy-to-use operation method. I hope it will be helpful to answer the doubt of "what is the Dubbo bean method of Mock injection?" Next, please follow the editor to study!

Recently, I refactored the back-end service with Spring cloud Alibaba, and during the unit test with Mockit, I found that the remote interface of dubbo would still be called. Debug finds that the @ Reference annotated interface and the @ MockBean object get two instances from the ApplicationContext, so do another layer on your own, and change it to a Mock proxy instance after Spring starts.

The code is as follows

Import org.apache.dubbo.config.annotation.Reference;import org.springframework.beans.BeansException;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.config.BeanPostProcessor;import org.springframework.context.ApplicationContext;import org.springframework.core.annotation.Order;import org.springframework.stereotype.Component;import java.lang.reflect.Field;import java.util.List;import java.util.Map;@Order@Componentpublic class MockerFactory implements BeanPostProcessor {@ Autowired private ApplicationContext applicationContext @ Override public Object postProcessBeforeInitialization (Object bean, String beanName) throws BeansException {return bean;} @ Override public Object postProcessAfterInitialization (Object bean, String beanName) throws BeansException {/ / only deals with if (bean.getClass (). GetPackage () = null | |! bean.getClass (). GetPackage (). GetName (). Contains ("business package name")) {return bean } List fields = org.apache.commons.lang3.reflect.FieldUtils.getAllFieldsList (bean.getClass ()); for (Field field: fields) {Reference reference = field.getAnnotation (Reference.class); Map beans = applicationContext.getBeansOfType (field.getType ()) / / replace the dubbo interface with the instance of mock proxy if (reference! = null & & beans.size () > 1) {field.setAccessible (true); setMockFieldToBean (bean, field, beans);}} return bean } private void setMockFieldToBean (Object bean, Field field, Map beans) {for (Object fieldBean: beans.values ()) {if (fieldBean.getClass (). GetName (). Contains ("$MockitoMock$")) {try {field.set (bean, fieldBean);} catch (IllegalAccessException e) {throw new RuntimeException (e) At this point, the study on "what is the Dubbo bean method of Mock injection" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
