解决跨域问题代码

Posted 2022-06-24 wangquanyi

此代码主要是为了解决跨域问题：

代码：

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;

@Configuration
public class CorsConfig 
    private CorsConfiguration buildConfig() 
        CorsConfiguration corsConfiguration = new CorsConfiguration();

        // 可以自行筛选
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");

        return corsConfiguration;
    

    @Bean
    public CorsFilter corsFilter() 
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

        source.registerCorsConfiguration("/**", buildConfig());

        return new CorsFilter(source);
