snack4 - JsonPath 应用参考

1、JsonPath 应用参考

应用示例

ONode oNode = ONode.ofBean(store);

oNode.select("$..book[?@.tags contains 'war'].first()").toBean(Book.class); //RFC9535 规范，可以没有括号
oNode.select("$..book[?(!(@.category == 'fiction') && @.price < 40)].first()").toBean(Book.class);
oNode.select("$.store.book.count()");

ONode.ofJson(store).create("$.store.book[0].category").toJson();

ONode.ofBean(store).delete("$..book[-1]");

2、表达式示例与说明

样本数据

{ "store": {
    "book": [
      { "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. R. R. Tolkien",
        "title": "The Lord of the Rings",
        "isbn": "0-395-19395-8",
        "price": 22.99
      }
    ],
    "bicycle": {
      "color": "red",
      "price": 399
    }
  }
}
