从Spring Boot 1.5.x升级到2.0.x时，@Crossorigin出现根中断

@CrossOrigin(origins = "http://example.com", methods = RequestMethod.GET, allowedHeaders = "header1")

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("http://example.com")
                .allowedMethods("GET")
                .allowedHeaders("header1")
                .allowCredentials(false)
                .maxAge(3600);
    }
}

spring.mvc.crossorigin.allowed-origins=http://example.com
spring.mvc.crossorigin.allowed-methods=GET
spring.mvc.crossorigin.allowed-headers=header1
spring.mvc.crossorigin.allow-credentials=false
spring.mvc.crossorigin.max-age=3600
