5：编写注解实现类： EnableUserInfoTransmitterAutoConfiguration

package spring.cloud.common.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import spring.cloud.common.interceptor.TransmitUserInfoFeighClientInterceptor;
import spring.cloud.common.filter.TransmitUserInfoFilter;

//@Configuration 在业务端通过注解EanbleUserInfoTransmitter加载
public class EnableUserInfoTransmitterAutoConfiguration {

  public EnableUserInfoTransmitterAutoConfiguration() {
  }

  @Bean
  public TransmitUserInfoFeighClientInterceptor transmitUserInfo2FeighHttpHeader(){
    System.out.println("-----TransmitUserInfoFeighClientInterceptor");
    return new TransmitUserInfoFeighClientInterceptor();
  }

  @Bean
  public TransmitUserInfoFilter transmitUserInfoFromHttpHeader(){
    System.out.println("-----TransmitUserInfoFilter");
    return new TransmitUserInfoFilter();
  }
}

6：编写注解 EnableUserInfoTransmitter

package com.test.domi.annotation;

import com.test.domi.config.EnableUserInfoTransmitterAutoConfiguration;
import org.springframework.context.annotation.Import;

import java.lang.annotation.*;

@Documented
@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Import({EnableUserInfoTransmitterAutoConfiguration.class})
public @interface EnableUserInfoTransmitter {
}

7：在启动类上标记注解即可使用（无侵入）

package com.test.domi;

import com.test.domi.annotation.EnableUserInfoTransmitter;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
@MapperScan("com.test.domi.dao")
@EnableUserInfoTransmitter
public class TestCommonClient {

  public static void main(String[] args){

    SpringApplication.run(TestCommonClient.class,args);
  }
}
