ajax添加token、Authorization请求跨域问题

package com.zrgk.yfs.framework.config;

import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;

import org.springframework.web.filter.CorsFilter;

/**

@Configuration
public class MyConfiguration {
    /**
     * 跨域
     *
     * @return
     */
    @Bean
    public FilterRegistrationBean<CorsFilter> corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        config.addExposedHeader("Authorization");
        config.setMaxAge(60 * 60 * 24L);

        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<CorsFilter>(new CorsFilter(source));
        bean.setOrder(FilterRegistrationBean.HIGHEST_PRECEDENCE);
        return bean;
    }

}

备注：：

添加完上述的跨域配置后还是不生效，最后查询到问题是过滤器加载顺序问题。需要将此跨域配置放在最前面。
