Reading a Document The simplest most straight forward way to use JsonPath is via the static read API. Stringjson="...";List<String>authors=JsonPath.read(json,"$.store.book[*].author"); If you only want to read once this is OK. In case you need to read an other path as well this...
3. Reading a File from the Classpath 3.1. Using Standard Java This section explains how to read a file that is available on a classpath. We’ll read the “fileTest.txt” available undersrc/main/resources: @Test public void givenFileNameAsAbsolutePath_whenUsingClasspath_thenFileData() { S...
