如何将 String 转换为 JsonPatch?

How to convert String to JsonPatch?

Java 我从数据库中检索到的字符串:

[
  { "op": "replace", "path": "/baz", "value": "boo" },
  { "op": "add", "path": "/hello", "value": ["world"] },
  { "op": "remove", "path": "/foo" }
]

如何将其转换为 JsonPatch 对象?

我正在使用 com.github.fge.jsonpatch 库。

根据JSON补丁文档,您可以使用Jackson反序列化构建一个JsonPatch实例。

 String json = "...";

 final ObjectMapper mapper = new ObjectMapper();
 final InputStream in = new ByteArrayInputStream(json.getBytes());
 final JsonPatch patch = mapper.readValue(in, JsonPatch.class);
