跨域资源共享 CORS

自定义Fitler方式

package org.hr.auth.config;

import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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 CorsConfig {

    @Bean
    public FilterRegistrationBean reqResFilter() {
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", config);
        CorsFilter corsFilter = new CorsFilter(source);
        FilterRegistrationBean<CorsFilter> registrationBean = new FilterRegistrationBean<>(corsFilter);
        registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return registrationBean;
    }

}

！！！重点！！！

registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);

不加他喵的就不好使！0都不行！狗不狗
