我终于找到了！正确的配置是这样的：
@Configuration
public class VersioningMappingHandlerConfig {
@Bean
public ApiVersionRequestMappingHandlerMapping customMappingHandlerMapping() {
ApiVersionRequestMappingHandlerMapping handler = new ApiVersionRequestMappingHandlerMapping("v", 1, 1);
handler.setOrder(-1);
return handler;
}
}
注意：没有extends WebMvcConfigurationSupport，bean名称是customMappingHandlerMapping
