if?(constraintViolationSet.size()>0){
????//有錯誤
????result.setErrorMsgMap(true);
????constraintViolationSet.forEach(constraintViolation->{
????????String?errMsg?=constraintViolation.getMessage();
????????String?propertyName=constraintViolation.getPropertyPath().toString();
????????result.getErrorMsgMap().put(propertyName,errMsg);
????});
}
其中result.setErrorMsgMap(true)??true報錯
