前后端分离跨域

1、需要放在Controller目录下面

2、代码如下：

package net.shopxx.api.controller;

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
        source.registerCorsConfiguration("/api/**", buildConfig()); // 对接口配置跨域设置
        return new CorsFilter(source);
    }
}
