Springboot配置跨域请求

直接找一个地方把java文件放入

package com.zpark.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;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CrosConfiguration implements WebMvcConfigurer {

//    @Override
//    public void addCorsMappings(CorsRegistry registry) {
//        registry.addMapping("/**")
//                .allowedOriginPatterns("*")
//                .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS")
//                .allowCredentials(true)
//                .maxAge(3600)
//                .allowedHeaders("*");
//    }

    // 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("*"); // 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);
    }
