口說無憑，直接上代碼

@Configuration

publicclassCorsConfig {

????privateCorsConfiguration buildConfig() {

????????CorsConfiguration corsConfiguration = newCorsConfiguration();

????????corsConfiguration.addAllowedOrigin("*");

????????corsConfiguration.addAllowedHeader("*");

????????corsConfiguration.addAllowedMethod("*");

????????returncorsConfiguration;

????}

????@Bean

????publicCorsFilter corsFilter() {

????????UrlBasedCorsConfigurationSource source = newUrlBasedCorsConfigurationSource();

????????source.registerCorsConfiguration("/**", buildConfig());

????????returnnewCorsFilter(source);

????}

}

1-新建配置文件，添加Configuration注解

2-測(cè)試跨域請(qǐng)求通過，至此已完美解決ajax跨域問題，是不是很easy，小伙伴兒們快去試試把!!!
