Spring boot跨域问题解决sprng boot 跨域支持

在每种Java编程或者其他语言的web项目中都可能存在着跨域调用的问题,文本主要针对Java编程语言中的spring boot项目跨域问题解决
 
解决办法其实很简单，创建一个过滤器，将需要支持跨域的url进行匹配,如下代码:

package com.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;
/***
*spring boot跨域过滤器
*
**/
@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*"); 
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*"); 
        return corsConfiguration;
    }

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

这是spring 处理跨域解决方案之一
