Description:

A component required a bean of type 'com.xx.support.feign.UxxxOFeign' that could not be found.


Action:

Consider defining a bean of type 'com.xx.support.feign.UxxxFeign' in your configuration.

Disconnected from the target VM, address: '127.0.0.1:3950', transport: 'socket'

Process finished with exit code 1

这是Feign接口的找不到bean，而不是其他类，这时候无论你写多少@Component都是没用的。

正确的解决方案是在启动类上做手段

@EnableJdSwagger2
@ComponentScan(basePackages = {"com.xx"})
@MapperScan("com.xx.xx.dao.mapper")
@EnableTransactionManagement(proxyTargetClass = true)
@SpringBootApplication(exclude = {DruidDataSourceAutoConfigure.class})
@EnableFeignClients(basePackages = { "com.xx.xx.services.integration"})
@EnableAsync
public class PxxxiApplication {

    public static void main(String[] args) {
        SpringApplication.run(PxxxiApplication.class, args);
    }
}

// 这个路径一定要能扫描到，看源码会发现他是个数组，意味着你可以传多个
@EnableFeignClients(basePackages = { "com.xx.xx.services.integration"})
