1-eureka开启了密码校验。客户端也要增加密码校验。保持一直

security:
  user:
    name: eureka1
    password: 123456

eureka:
  instance:
    hostname: localhost
  client:
    #配置eureka服务器地址
    service-url:
      defaultZone: http://eureka1:123456@127.0.0.1:8099/eureka
    #是否将自己注册到注册中心
    register-with-eureka: false
    # 是否需要搜索信息服务
    fetch-registry: false

2-开启了SpringSecurity校验 没有将csrf禁用

/**
 * 这是一个全局配置
 * 实际开发中请将他配置在全局中
 */
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    /**
     * eureka开启了SpringSecurity，必须将csrf禁用
     * 将SpringCloudEureka 中配置的SpringSecurity 的csrf配置信息禁止
     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest()
                .permitAll()
                .and().httpBasic()
                .and().csrf().disable();
    }
}
