The client registers Can not execute request on any known server solved

After adding secure authentication of eureka registry server, the new version springcloud there is a problem that is registered to the service center Times in client a mistake: Can not execute request on any known server, again carefully looked at the official document Securing The Eureka Server part is resolved.

Add security authentication: https://www.cnblogs.com/zrk3/p/springcloud_securing_eurekaserver.html

First, official documents

 

 url: https://cloud.spring.io/spring-cloud-static/Finchley.SR2/multi/multi_spring-cloud-eureka-server.html#_securing_the_eureka_server

The effect (English is not good, forgive me):

Simply Spring -boot-starter- security will be added to the service path Spring Security, you can protect the Eureka service. By default, when Spring Security on the classpath it will require a valid CSRF sends a token every time the transmission request to the application. Eureka client does not usually have a valid token cross-site request forgery (CSRF), you need to disable this request / Eureka / ** endpoints

2. Add a profile

Add a profile in eureka service project:

 

 

package com.zrk.config;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 * @Description:
 * @Author: zrk
 * @Date: 2019/9/12
 */
@EnableWebSecurity
class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().ignoringAntMatchers("/eureka/**");
        super.configure(http);
    }
}

Restart eureka service, restart the client discovered already registered successfully.
