java跨域公共類 ------java公共類彙總之系列之二

情景:前後端要想打通，需要解決跨域問題,記錄一下跨越公共類編寫.

代碼如下：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.core.Ordered;

/**
 * 處理AJAX請求跨域的問題
 */
@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");

        corsConfiguration.addAllowedHeader("Origin");
        corsConfiguration.addAllowedHeader("No-Cache");
        corsConfiguration.addAllowedHeader("X-Requested-With");
        corsConfiguration.addAllowedHeader("If-Modified-Since");
        corsConfiguration.addAllowedHeader("Cache-Control");
        corsConfiguration.addAllowedHeader("Pragma");
        corsConfiguration.addAllowedHeader("Expires");
        corsConfiguration.addAllowedHeader("Content-Type");
        corsConfiguration.addAllowedHeader("X-E4M-With");
        corsConfiguration.addAllowedHeader("X-User-Token");
        corsConfiguration.addAllowedHeader("Authorization");

        corsConfiguration.addAllowedMethod("GET");
        corsConfiguration.addAllowedMethod("POST");
        corsConfiguration.addAllowedMethod("HEAD");
        corsConfiguration.addAllowedMethod("PUT");
        corsConfiguration.addAllowedMethod("DELETE");
        corsConfiguration.addAllowedMethod("OPTIONS");

        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }

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

ok 就到這裏啦
