这两天对公司后台管理代码进行Spring cloud 版本升级发现eureak客户端无法注册到注册中心，控制台日志报错如下，看异常没看出来问题，看警告信息里有一个 "Request execution failure with status code 403; retrying on another server if available" 这个提示，说明注册鉴权的时候失败了

经过百度后找到了解决办法，但是可能会造成服务不安全，暂时没时间研究
解决办法就是在注册中心服务关闭csrf 安全认证(不影响页面登录)
@EnableWebSecurity
static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().ignoringAntMatchers("/eureka/**");
super.configure(http);
}
}
