springboot+cors跨域处理

项目中遇到跨域问题你们怎么处理的呢，这里提供cors跨域作为参考
，项目使用springboot，具体逻辑就不说了，很简单，搜索一下就懂了，这里直接上代码吧

package com.cui.boot.config;

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;

/**
 * @author tian
 * @description cors跨域
 * @create 2019-01-24 17:00
 */
@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        //1
        corsConfiguration.addAllowedOrigin("*");
        //2
        corsConfiguration.addAllowedHeader("*");
        //3
        corsConfiguration.addAllowedMethod("*");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        //4
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
}

或者

package com.cui.boot.config;

import org.springframework.context.annotation.Bean;
import org.springframework.http.HttpMethod;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

/**

 */
public class SimpleCorsConfig {
    /**
     * 设置 跨域请求参数，处理跨域请求
     *
     * @return
     */
    @Bean
    public CorsFilter corsFilter()
    {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }

    private CorsConfiguration buildConfig()
    {
        CorsConfiguration corsConfiguration = new CorsConfiguration();

        // 允许跨域访问的域名
        corsConfiguration.addAllowedOrigin("*");
        // 请求头
        corsConfiguration.addAllowedHeader("*");
        // 请求方法
        corsConfiguration.addAllowedMethod(HttpMethod.DELETE);
        corsConfiguration.addAllowedMethod(HttpMethod.POST);
        corsConfiguration.addAllowedMethod(HttpMethod.GET);
        corsConfiguration.addAllowedMethod(HttpMethod.PUT);
        corsConfiguration.addAllowedMethod(HttpMethod.DELETE);
        corsConfiguration.addAllowedMethod(HttpMethod.OPTIONS);
        // 预检请求的有效期，单位为秒。
        corsConfiguration.setMaxAge(3600L);
        // 是否支持安全证书
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }
}

其实配置都差不多，能解决问题的就是好代码，上述配置选一个就可以
