```java FluentValidator.checkAll() .configure(new SimpleRegistry()) .on(car) .doValidate(new SimpleValidateCallback()); ``` class car may like this: ``` class car{ ... @FluentValidate(SimpleDataValidator.class) private String startTime; @FluentValidate(SimpleDataValidator.class) private String endTime; ... } ``` When I use this method, only first filed of car's tow same validator was validated, validator worked on `startTime`, ignored `endTime`.
