How to get json path in java when the json value has hyphen?

I have com.jayway.jsonpath.InvalidPathException.

Error message:

JSON Path:

$.data.storeGtin.assignmentInfo.assignedLocations[*].assignments[?(@.barcode='w422-5r72' && @.eslTag!='null')].modular.category.department.departmentNumber

Solution

The following path expression finds the value 17 for departmentNumber, in the corrected (valid) version of your JSON. The result is actually a JSONArray - but it only contains 1 value - the 17.

You can compare it with your version to see the differences - and decide for yourself if this is what you do actually need.

$.data.storeGtin.assignmentInfo.assignedLocations[*].assignments[*].assignments[?(@.eslTag != null && @.eslTag.barcode == 'w422-5r72')].modular.category.department.departmentNumber

Basically:

the original expression was missing a level for the 2nd assignments array.
eslTag is an object in your sample, so I assume the comparison should be against null not 'null'.
the barcode comparison should refer to eslTag.barcode, and not simply barcode.
the "equals to" operator is ==, not =.

Reference.

The point in the question about "when the value has a hyphen" was not actually relevant to the problem.
