springboot处理跨域的解决方案

动静分离之后，springboot处理跨域的解决方案。参考地址https://gitee.com/alohasir/manli-cloud-boot.git

package com.manlitech.cloudboot.basebootconfig.config;
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;
import java.util.Collections;
/**

@Configuration
public class CorsConfig {

@Bean
public CorsFilter corsFilter() {
    final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
    final CorsConfiguration corsConfiguration = new CorsConfiguration();
    /*是否允许请求带有验证信息*/
    corsConfiguration.setAllowCredentials(true);
    /*springboot 2.4 之后需要注释 允许访问的客户端域名*/
    //corsConfiguration.addAllowedOrigin("*");
    /*springboot 2.4 之后需要增加 允许任何来源*/
    corsConfiguration.setAllowedOriginPatterns(Collections.singletonList("*"));
    /*允许服务端访问的客户端请求头*/
    corsConfiguration.addAllowedHeader("*");
    /*允许访问的方法名,GET POST等*/
    corsConfiguration.addAllowedMethod("*");
    urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
    return new CorsFilter(urlBasedCorsConfigurationSource);
}

}
