在建文件复制进去即可
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;
@Configuration
public class CorsConfig {
// 当前跨域请求最大有效时长。这里默认1天
private static final long MAX_AGE = 24 * 60 * 60;
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("http://localhost:8080"); // 1 设置访问源地址
corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
corsConfiguration.setMaxAge(MAX_AGE);
source.registerCorsConfiguration("/**", corsConfiguration); // 4 对接口配置跨域设置
return new CorsFilter(source);
}
}
重启前后端服务之后就不会报错
