无法在Eureka注册我的微服务

提问于

我配置了一台Eureka服务器（它正在工作，我可以连接到它并看到Eureka控制台），但我的微服务不会在其中注册 . 我收到403服务器错误（禁止） . 尝试注册的微服务中的身份验证配置似乎没问题，好像我故意设置错误，我得到401 .

我的gradle配置：

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
        gradleDockerVersion   = '1.2'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "io.spring.gradle:dependency-management-plugin:0.5.6.RELEASE"
        classpath("se.transmode.gradle:gradle-docker:${gradleDockerVersion}")
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}
ext {
    springCloudVersion = 'Finchley.RELEASE'
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
        mavenBom("org.springframework.boot:spring-boot-dependencies:${springBootVersion}")
        mavenBom 'org.springframework.cloud:spring-cloud-netflix:2.0.1.RELEASE'
    }
}

这是我的配置 . 我已将它包含在bootstrap.yaml和配置服务器中，以确保：

eureka:
  client:
    serviceUrl:
      defaultZone: http://myuserid:mypassword@localhost:8761/eureka/

但由于某种原因，它被忽略了 . 该属性的根源是“eureka”，而不是“spring.eureka ......”？

这是微服务中的错误日志，它似乎在尝试localhost和标准端口8080，因此忽略了上面的配置 .

    我终于发现当前Eureka Server中存在一个错误，在这个答案中描述：

    https://github.com/spring-cloud/spring-cloud-netflix/issues/2754#issuecomment-372808529

    因此，将以下@EnableWebSecurity代码添加到Gateway Spring Boot应用程序服务器类可修复它：

    import org.springframework.context.annotation.Configuration;
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;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@Configuration
@EnableAutoConfiguration
@EnableEurekaServer
@SpringBootApplication
public class DiscoveryApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(DiscoveryApplication.class).run(args);
    }

    @EnableWebSecurity
    static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable();
        }
    }
}
