1、实现WebMvcConfigurer接口

package com.common.config;import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;@Configuration
public class CorsConfig implements WebMvcConfigurer {@Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping("/**") .allowedOrigins("*") .allowedMethods("*")  .maxAge(3600).allowCredentials(true);}}

 2、配置Bean过滤器

package com.common.config;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  {private CorsConfiguration buildConfig(){CorsConfiguration corsConfiguration = new CorsConfiguration();corsConfiguration.addAllowedOrigin("*");corsConfiguration.addAllowedHeader("*");corsConfiguration.addAllowedMethod("*");return corsConfiguration;}@Beanpublic CorsFilter corsFilter(){UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();source.registerCorsConfiguration("/**",buildConfig());return new CorsFilter(source);}}
