spring boot之配置跨域

在启动类中配置

@Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedOrigins("*")
                        .allowedMethods("GET", "POST")
                        .allowCredentials(true).maxAge(3600);
            }
        };
    }
