Springboot配置全局跨域

2.x全局配置

第一种

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;
 
/**
 * @author zhi
 * @date 2021/6/17
 */
@Configuration
public class CrossOriginConfig {
 
    /**
     * 配置全局跨域
     */
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOriginPattern("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }
 
    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
 
}

第二种

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;

@Configuration
public class CorsConfiguration {

    @Bean
    public CorsWebFilter corsWebFilter(){
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

        CorsConfiguration corsConfiguration = new CorsConfiguration();

        //配置跨域
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.setAllowCredentials(true);
        source.registerCorsConfiguration("/**",corsConfiguration);
        return new CorsWebFilter(source);
    }
}

2.x之前全局配置

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

@Configuration
public class CorsFilterConfiguration extends WebMvcConfigurationSupport {
    @Override
    protected void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").
                allowCredentials(true)
                .allowedHeaders("*")
                .allowedMethods("*")
                .allowedOriginPatterns("*");
        super.addCorsMappings(registry);
    }
}
