eureka server 集成security，eureka client报错com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

当前Spring Coud 版本(Greenwich.SR2)  Spring Boot版本 (2.1.6.RELEASE)

在eureka server 中集成security后,发现eureka client 去注册的时候报以下错误:

There was a problem with the instance info replicator

eureka server 中的配置文件:

eureka client中的配置文件:

很奇怪,注册不进去了

这时候需要在eureka server 中创建一个

SecurityConfig.java文件

package **.**.**;
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;

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();//关闭SpringSecurity的CSRF保护
        super.configure(http);
    }
}

然后重启eureka server,完美解决报错问题
