文章将会围绕以下几个问题展开讨论 1. 什么时候为@FeignClient注解的接口生成代理? 2. Contract 、Encoder、Expander、AnnotatedParameterProcessor之间的关系? 3. 怎么变成具体的请求参数? 3. Feign的请求发送流程 feign 初始化 ========== EnableFeignClients注解引入 FeignClientsRegistrar.class FeignClientsRegistrar 实现 ImportBeanDefinitionRegistrar接口,是在容器中动态添加spring bean的类。FeignClientsRegistrar 通过 registerBeanDefinitions 方法的 registerFeignClients(),扫描所有通过@FeignClient注解的接口,并为每个接口 创建一个FeignClientFactoryBean类,注册在spring的 BeanDefinitionRegistry。spring 容器初始化时,FeignClientFactoryBean#getObject 为每个feignClient接口生成代理。 生成代理的时候对契约进行校验。 SpringMvcContract 初始化时
