[Java知识库]springboot使用CorsConfig解决跨域问题

上代码

package com.vector.sportplay.util;

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;
//全局配置类,配置跨域请求
@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.setAllowCredentials(Boolean.TRUE);//
        corsConfiguration.addAllowedMethod("*");//允许任何请求方法
        // 当前跨域请求最大有效时长,这里设置1小时
        corsConfiguration.setMaxAge((long) 3600);
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
}
