Emiter :
I'm trying to filter jsonPath by type. To extract Integers
I would expect this will return nothing as 'xx' is not integer:
JsonPath.read("{'status': 'xx'}", "$.status", Criteria.where(".status").is(Integer.class));
Similarly this
JsonPath.read("{'status': 'xx'}", "$.status", Criteria.where(".status").eq(200));
both cases returns String = "xx" I would expect it to return either null or empty string as it doesn't match number 200.
dZ. :
Correct @i.bondarenko, I would simply add - for the first check of searching whether status value is an Integer - that he/she should use a Pattern to pass to the filter, like for example
Pattern numberPattern = Pattern.compile("\\d+");
Filter filter = filter(where("status").regex(numberPattern));
Object test = JsonPath.read("{\"status\": \"xx\"}", "$[?].status", filter);
System.out.println("Test : " + test);
That will print Test : []
UPDATED
It is a JSONArray indeed, therefore, you already have the Integers of your whole JSON in that array (if they exist). For example,
Pattern numberPattern = Pattern.compile("\\d+");
Filter filter = filter(where("status").regex(numberPattern));
net.minidev.json.JSONArray test = JsonPath.read("{\"status\": 300}", "$[?].status", filter);
if (!test.isEmpty()) {
for (Object object : test) {
System.out.println("Test : " + object.toString());
}
}
So, there is no need to add try-catch, it is enough to just check the size of your JSONArray result
