1、nginx配置

proxy_set_header Host $host;
proxy_pass http://127.0.0.1:8080;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto  $scheme;

2、Spring Boot 配置（在启动类里面配置,此方法为Spring Boot 2.X以上）

@Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.setUriEncoding(Charset.forName("UTF-8"));
        RemoteIpValve value = new RemoteIpValve();
        value.setRemoteIpHeader("X-Forwarded-For");
        value.setProtocolHeader("X-Forwarded-Proto");
        value.setProtocolHeaderHttpsValue("https");
        factory.addEngineValves(value);
        return factory;

3、若是war包，在tomcat的在server.xml的Engine模块下面配置多一个以下的Valve

<Valve  className="org.apache.catalina.valves.RemoteIpValve" 
        remoteIpHeader="X-Forwarded-For" 
        protocolHeader="X-Forwarded-Proto" 
        protocolHeaderHttpsValue="https"/>
