简单使用


  @Test
  public void userJsonPath(){
    DocumentContext context = JsonPath.parse(json);
    Object read1 = context.read("$..book");
    System.out.println(read1);
    Object read2 = context.read("$..book[0].price");
    System.out.println(read2);
    context.set("$..book[0].price",10.00);
    Object read3 = context.read("$..book[0].price");
    System.out.println(read3);
  }

输出:

[[{"category":"reference","author":"Nigel Rees","title":"Sayings of the Century","price":8.95},{"category":"fiction","author":"Evelyn Waugh","title":"Sword of Honour","price":12.99},{"category":"fiction","author":"Herman Melville","title":"Moby Dick","isbn":"0-553-21311-3","price":8.99},{"category":"fiction","author":"J.
