关于springboot:Spring-Boot-Feign调用原理探究

32次阅读

共计 25687 个字符，预计需要花费 65 分钟才能阅读完成。

单元测试类如下：

@SpringBootTest(classes = Application.class)
@RunWith(SpringRunner.class)
public class Test{
    @Resource
    private AdSupportAccount adSupportAccount;
    @Test
    publict void test(){adSupportAccount.list(accountInfoQuery);
    }
}

Feign 申明如下：

@FeignClient(value = "account-provider", url = "${account}")
public interface AdSupportAccount {

    /**
     * 分页查问 account 列表
     *
     * @param accountInfoQuery
     * @return
     */
    @PostMapping("accountInfo/list")
    KkbResponse<Map<String, Object>> list(@RequestBody AccountInfoQuery accountInfoQuery);
}

debug 能够看到 AdSupportAccount 实例其实被代理类 FeignINvocationHandler 持有

截取第一行信息 

doGetObjectFromFactoryBean:177, FactoryBeanRegistrySupport (org.springframework.beans.factory.support)

能够看到咱们申明的 AdSupportAccount 实例对象：

其实是 FeignInvocationHandler.ReflectiveFeign; 这样一来久首尾呼应了！
