解决方案

在eureka注册中心启动类添加以下代码

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

解决方法2

http.csrf().disable().httpBasic();
