跨域啥的还是要后端来做！

package com.zcw.conf; 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; /** * 实现基本的跨域请求 * @author linhongcun * */ @Configuration public class CorsConfig { private CorsConfiguration buildConfig() { CorsConfiguration corsConfiguration = new CorsConfiguration(); corsConfiguration.addAllowedOrigin("*"); // 允许任何域名使用 corsConfiguration.addAllowedHeader("*"); // 允许任何头 corsConfiguration.addAllowedMethod("*"); // 允许任何方法（post、get等） return corsConfiguration; } @Bean public CorsFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", buildConfig()); // 对接口配置跨域设置 return new CorsFilter(source); } }
