解决方法:

• 1. 对应controller添加注解@CrossOrigin
• 2. CorsConfig配置

@Configuration
public class CorsConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/*")
                .allowedOrigins("*")
                .allowCredentials(true)
                .allowedMethods("GET", "POST", "DELETE", "PUT","PATCH")
                .allowedHeaders("*")
                .maxAge(3600);
    }
}

application.yml中 authc-urls:拦截所有就会报错,注释后能通过,为什么?

最终处理

不需要每个controller添加 @CrossOrigin注解

@Configuration
public class CorsAutoConfig {

    @Bean
    public CorsFilter corsFilter(){
        UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource=new UrlBasedCorsConfigurationSource();
        CorsConfiguration corsConfiguration=new CorsConfiguration();
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        urlBasedCorsConfigurationSource.registerCorsConfiguration("/**",corsConfiguration);

        CorsFilter corsFilter=new CorsFilter(urlBasedCorsConfigurationSource);
        return corsFilter;
    }
}
