fastjson2如何通过JSONReader解析大json

jastjson升级到fastjson2后，如何通过JSONReader解析大json

升级前实现示例
JSONReader reader = getJSONReader(json);
reader.startObject();
while (reader.hasNext()) {
String key = reader.readString();
if ("name1".equals(key)) {
setInitNodeProgress(reader.readString());
} else if ("name2".equals(key)) {
treeHtmlEntity.setTreeType(reader.readString());
} else if ("name3".equals(key)) {
treeHtmlEntity.setLang(reader.readString());
} else if ("name4".equals(key)) {
treeHtmlEntity.setProdId(reader.readString());
} else if ("name5".equals(key)) {
parsesJsonArray(reader.readString(), multiFilterList);
} else {
reader.readObject();
}
}
reader.endObject();
reader.close();
想知道升级后如何实现

Start with the JSONReader entry points shown in the issue and compare the pre-upgrade calls with the fastjson2 API and migration documentation. Done means documenting how to parse a large JSON object after the upgrade, including handling the named fields, skipped values, and reader lifecycle.
