解决Springboot 的ajax跨域问题-动静分离

@SpringBootApplication
public class FsSysApiApp {
    public static void main(String[] args) {
        SpringApplication.run(FsSysApiApp.class, args);
    }
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedOrigins(new String[]{"http://b.aa.com:12345"
                                        ,"http://b.aa.com","http://c.aa.com"});
            }
        };
    }
}
