添加全局 Cors 过滤配置类：

package com.xiaosheng.developer.common.support.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;
    
    /** * @description: * @author: wangzibin **/
    @Configuration
    public class GlobalCorsConfig { 
    
        @Bean
        public CorsFilter corsFilter(){ 
            //1.添加CORS配置信息
            CorsConfiguration config = new CorsConfiguration();
            //放行哪些原始域
            config.addAllowedOrigin("*");
            //是否发送Cookie信息
            config.setAllowCredentials(true);
            //放行哪些原始域(请求方式)
            config.addAllowedMethod("*");
            //放行哪些原始域(头部信息)
            config.addAllowedHeader("*");
            //暴露哪些头部信息（因为跨域访问默认不能获取全部头部信息）
    // config.addExposedHeader("*");
    
            config.addExposedHeader("Content-Type");
            config.addExposedHeader( "X-Requested-With");
            config.addExposedHeader("accept");
            config.addExposedHeader("Origin");
            config.addExposedHeader( "Access-Control-Request-Method");
            config.addExposedHeader("Access-Control-Request-Headers");
    
            //2.添加映射路径
            UrlBasedCorsConfigurationSource configSource = new UrlBasedCorsConfigurationSource();
            configSource.registerCorsConfiguration("/**", config);
    
            //3.返回新的CorsFilter.
            return new CorsFilter(configSource);
        }
    }

完事。
