springboot解决接口跨域问题

 

 

CorsConfig跨域配置类一

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 java.util.Arrays;

/**
 * @author junqi.pi
 */

@Configuration
public class CorsConfig {
    @Bean
    public CorsFilter corsFilter() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        final CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
//        允许所有域名跨域
        config.setAllowedOrigins(Arrays.asList("*"));
//        允许所有请求头
        config.setAllowedHeaders(Arrays.asList("*"));
//        允许所有方法
        config.setAllowedMethods(Arrays.asList("*"));
        config.setMaxAge(300L);
        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);

    }
}

CorsConfig跨域配置类二

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @author junqi.pi
 */
@Configuration
public class CorsConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {

        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowCredentials(true)
                .allowedMethods("*")
                .maxAge(1728000);
    }
}

 

选择一种当成工具类直接添加进项目里就行了

但是这种方法是允许所有的跨域请求 有一定的安全性问题 后期再优化  请谨慎选择
