这是因为Security在新的版本中，默认开启了`csrf`，关闭即可：

在eureka服务中加入以下配置：

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 {
    
        /**
         *  关闭 csrf
         * @param http
         * @throws Exception
         */
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable();
    
        }
    }
