项目我用的是解决方法2，可以成功

@Configuration
public class CorsConfig implements WebMvcConfigurer {

@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowCredentials(true)
.allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
.maxAge(3600);
}
}
