在zuul中通过过滤器配置跨域后，其它请求没问题，但是post请求403。

spring cloud 跨域问题 在 zuul 使用 ZuulFilter 解决

还有一种方式通过@Configuration配置后可以正常处理post跨域请求

import org.springframework.boot.context.embedded.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
public class MyConfiguration {

	@Bean
	public FilterRegistrationBean corsFilter() {
		UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
		CorsConfiguration config = new CorsConfiguration();
		config.setAllowCredentials(true);
		//config.addAllowedOrigin("http://domain1.com");
		config.addAllowedOrigin("*");
		config.addAllowedHeader("*");
		config.addAllowedMethod("*");
		source.registerCorsConfiguration("/**", config);
		FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
		bean.setOrder(0);
		return bean;
	}
}
