springboot和前端实现跨域交互

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

	//可以实现跨域交互
    @Bean
    public WebMvcConfigurer webMvcConfigurer(){
        return  new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("*");
            }
        };
    }
