SpringCloud———Eureka依赖问题

发表于 | 分类于 | |
异常问题

最近在学习SpringCloud时，添加eureka依赖时，一直无法成功导入，@EnableEurekaServer一直导不进去，经过百度最终找到原因是springboot与springcloud的支持版本不一致，写篇博客记录下来。修改pom.xml文件如下。

server:

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://localhost:10000/eureka

#security:
#  basic:
#    enabled: true #开启 方法已过时

  authorizeRequests():
    antMatchers("/**"):
      permitAll();:

spring:
  security:
    user:
      name: admin
      password:  admin
  • spring.application.name：服务名称
  • server.port：服务端口号
  • eureka.client.service-url.defaultZone：Eureka默认的服务地址空间信息配置
  • eureka.client.fetch-registry：是否从其他Eureka注册中心同步服务列表（单节点无需配置启用）.
  • eureka.client.register-with-eureka：是否将自己作为服务注册到其他Eureka服务注册中心（单节点无需配置启用）
注意事项

security.basic.enabled 配置过时或不可用解决：需要自己实现一个配置类继承自WebSecurityConfigurerAdapter，并重写configure(http)方法

    @Bean
    @Override
