Eureka服务端开启密码的认证比较简单
在pom文件中加入:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
配置如下:
server:
port: 5000
spring:
application:
name: EurekaServer
security:
user:
name: admin
password: 123456
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/
网页登录Eureka的管理中心时,能够正常登录,此时说明服务端配置成功
配置客户端
eureka: instance: prefer-ip-address: true client: service-url: defaultZone: http://admin:123456@localhost:5000/eureka/
但是启动客户端之后出现如下报错:

查资料找到解决办法如下:
服务端新建配置类,禁用CSRF,并启用httpBasic,代码如下:
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; @Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable().httpBasic(); //http.httpBasic(); } }
重新启动,看到客户端已经可以正常注册了
