本文介绍了一个使用Spring Boot实现跨域请求的方法。通过创建一个名为SecurityCorsConfiguration的类，并利用@Bean注解来定义一个FilterRegistrationBean实例，实现了允许特定源进行跨域访问的功能。配置中允许了凭据的传递，并对指定的URL模式设置了跨域访问规则。

import org.springframework.boot.web.servlet.FilterRegistrationBean;

import org.springframework.core.Ordered;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

/**

@Configuration
public class SecurityCorsConfiguration {
    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("http://127.0.0.1:8020");
        config.addAllowedHeader(CorsConfiguration.ALL);
        config.addAllowedMethod(CorsConfiguration.ALL);
        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return bean;
    }
}
