动态代理接口并注册到spring容器

package com.sz.register; import org.springframework.beans.BeansException; import org.springframework.beans.factory.config.ConfigurableListableBeanFactory; import org.springframework.beans.factory.support.BeanDefinitionBuilder; import org.springframework.beans.factory.support.BeanDefinitionRegistry; import org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor; import org.springframework.beans.factory.support.GenericBeanDefinition; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; import com.sz.test.TestService; @Component public class MyRegistryBean implements ApplicationContextAware,BeanDefinitionRegistryPostProcessor{ private ApplicationContext ctx; @Override public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException { } @Override public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanDefinitionRegistry) throws BeansException { // 需要被代理的接口 Class<?> cls = TestService.class; BeanDefinitionBuilder builder = BeanDefinitionBuilder.genericBeanDefinition(cls); GenericBeanDefinition definition = (GenericBeanDefinition) builder.getRawBeanDefinition(); definition.getPropertyValues().add("interfaceClass", definition.getBeanClassName()); definition.setBeanClass(MyProxyFactory.class); definition.setAutowireMode(GenericBeanDefinition.AUTOWIRE_BY_TYPE); // 注册bean名,一般为类名首字母小写 beanDefinitionRegistry.registerBeanDefinition("testService", definition); } @Override public void setApplicationContext(ApplicationContext ctx) throws BeansException { this.ctx = ctx; } }
