SpringBoot中如何解决VUE跨域呢?

解决VUE跨域问题
       我们只需在SpringBoot中编写相应的配置类即可

 package com.java265.configuration;
 
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;
 
/**
 * SpringBoot CROS跨域配置对象
 * @author java265.com
 *
 */
@Configuration
public class GlobalCorsConfig {
	 @Bean
	    public CorsFilter corsFilter() {
	        //1.添加CORS配置信息
	        CorsConfiguration config = new CorsConfiguration();
	          //放行哪些原始域
	          config.addAllowedOrigin("*");
	          //是否发送Cookie信息
	          config.setAllowCredentials(true);
	          //放行哪些原始域(请求方式)
	          config.addAllowedMethod("*");
	          //放行哪些原始域(头部信息)
	          config.addAllowedHeader("*");
	          //暴露哪些头部信息（因为跨域访问默认不能获取全部头部信息）
	          // config.addExposedHeader("*");
	          
	          config.addExposedHeader("Content-Type");
	          config.addExposedHeader( "X-Requested-With");
	          config.addExposedHeader("accept");
	          config.addExposedHeader("Origin");
	          config.addExposedHeader( "Access-Control-Request-Method");
	          config.addExposedHeader("Access-Control-Request-Headers");
 
 
	        //2.添加映射路径
	        UrlBasedCorsConfigurationSource configSource = new UrlBasedCorsConfigurationSource();
	        configSource.registerCorsConfiguration("/**", config);
 
	        //3.返回新的CorsFilter.
	        return new CorsFilter(configSource);
	    }
}
