更新：有點錯誤
//try as non-string using equal
Path pathFilterNonString = getPath(filter.getKey(), site, siteType);
Class pathType = pathFilterNonString.getJavaType();
if (pathType.equals(Long.class)){
try{
filterCondition = cb.and(filterCondition, cb.equal(pathFilterNonString, Long.valueOf(filter.getValue())));
}catch(java.lang.NumberFormatException nfe){
//ignore
//java.lang.NumberFormatException: For input string: "a"
}
}else if (pathType.equals(Timestamp.class)){
try{
filterCondition = cb.and(filterCondition, cb.equal(pathFilterNonString, Timestamp.valueOf(filter.getValue())));
}catch(java.lang.IllegalArgumentException e){
//ignore
//java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]
}
