springboot cloud 2.1.12 版本 eureka 开启 security 后导致 client 不能连接到注册中心 server 问题解决方法

springboot 版本

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.12.RELEASE</version>
		<relativePath />

springCloud 版本

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Greenwich.RELEASE</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

启动报错
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

解决方法：在 eureka 注册中心启动类添加如下代码

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

eurek server 配置文件 application.yml

server:
  port: 8761

spring:
  security:
    user:
      name: user
      password: 123456
      
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://user:123456@localhost:8761/eureka/
​

😂！！ 注意 defaultZone 不要写成 default-zone，不然也会出错
