Java 中 JsonPatch 接口的重要性?
javajsonobject oriented programmingprogramming
JsonPatch 接口是一种用于存储可应用于目标 JSON 结构的操作序列的格式。添加、删除、替换、复制、移动和测试等一些操作可以存储在JsonPath 中并在 JSON 结构上进行操作。JsonPatchBuilder 接口可用于使用Json.createPatchBuilder()构建 JSON 补丁。
JSON 文件
示例
import java.io.*;
import javax.json.Json;
import javax.json.JsonPatch;
import javax.json.JsonPatchBuilder;
import javax.json.JsonReader;
import javax.json.JsonStructure;
public class JsonPatchTest {
public static void main(String[] args) throws Exception {
JsonPatchBuilder jsonPatchBuilder = Json.createPatchBuilder();
JsonPatch jsonPatch = jsonPatchBuilder.add("/postalCode", "500072").remove("/age").build();
JsonReader reader = Json.createReader(new FileReader("simple.json"));
JsonStructure jsonStructure1 = reader.read();
JsonStructure jsonStructure2 = jsonPatch.apply(jsonStructure1);
System.out.println(jsonStructure2);
reader.close();
}
}
输出
{"firstName":"Raja","lastName":"Ramesh","streetAddress":"Madhapur","city":"Hyderabad","state":"Telangana","phoneNumbers":[{"Mobile":"9959984000"},{"Home":"7702144400"}],"postalCode":"500072"}
