JSON映射字段。可映射成对象或数组
因为项目对接了jira，jira api查询的数据太复杂且没有固定格式，所以写了一个简单的映射
// 原始数据

我想取
projects.issuetypes.id和projects.issuetypes.name
// 解析后数据
[
{
"issueTypeId": "10002",
"issueTypeName": "任务"
},
{
"issueTypeId": "10003",
"issueTypeName": "开发子任务"
},
{
"issueTypeId": "10001",
"issueTypeName": "故事"
},
{
"issueTypeId": "10202",
"issueTypeName": "测试用例"
},
{
"issueTypeId": "10203",
"issueTypeName": "测试计划"
},
{
"issueTypeId": "10204",
"issueTypeName": "缺陷"
}
]
代码如下
/**

public class JsonAdapter extends AbstractAdapter implements AdapterExecute {
public JsonAdapter(Map map) {
super(map);
}
private static void parseObject(String data, List> out, String parentKey, Map map, Map entity) {
JSONObject jsonObject = JSON.parseObject(data);
for (Map.Entry entry : jsonObject.entrySet()) {
String key = entry.getKey();
Object value = entry.getValue();
if (value instanceof JSONArray) {
if (Func.isNotBlank(parentKey)) {
parseArray(JSON.toJSONString(value), parentKey + "." + key, out, map);
} else {
parseArray(JSON.toJSONString(value), key, out, map);
}
} else if (value instanceof JSONObject) {
if (Func.isNotBlank(parentKey)) {
parseObject(JSON.toJSONString(value), out, parentKey + "." + key, map, entity);
} else {
parseObject(JSON.toJSONString(value), out, key, map, entity);
}
} else {

entity.put(map.get(key), value);
} else if (Func.isNotBlank(parentKey) && map.containsKey(parentKey + "." + key)) {
entity.put(map.get(parentKey + "." + key), value);
}
}
}
}
private static void parseArray(String data, String parentKey, List> out, Map map) {
JSONArray ja = JSONArray.parseArray(data);
for (int i = 0; i < ja.size(); i++) {
Object foreachJa = ja.get(i);
if (foreachJa instanceof JSONArray) {
parseArray(JSON.toJSONString(foreachJa), parentKey, out, map);
} else if (foreachJa instanceof JSONObject) {
Map entity = new HashMap<>();
out.add(entity);
parseObject(JSON.toJSONString(foreachJa), out, parentKey, map, entity);
}
}
}
@Override
public R> oneData(String data) {
List> maps = allData(data);
return Func.isNotEmpty(maps) ? R.data(maps.get(0)) : R.data(new HashMap<>());
}
public List> allData(String data) {
Object parse = JSON.parse(data);
List> out = new ArrayList<>();
if (parse instanceof JSONArray) {
parseArray(data, null, out, map);
} else if (parse instanceof JSONObject) {
Map entity = new HashMap<>();
out.add(entity);
parseObject(data, out, null, map, entity);
}
CopyOnWriteArrayList> list = new CopyOnWriteArrayList(out);
list.removeIf(Func::isEmpty);
return list;
}
@Override
public R>> pageData(String data, Query query) {
IPage> page = Condition.getPage(query);
List> maps = allData(data);
List> pageData = maps.stream().skip((page.getCurrent() - 1) * page.getSize()).limit(page.getSize()).collect(Collectors.toList());
page.setRecords(pageData);
page.setTotal(maps.size());
return R.data(page);
}
}
使用方式
Map map = new HashMap<>();
// 字段映射
map.put("projects.issuetypes.id","issueTypeId");
map.put("projects.issuetypes.name","issueTypeName");
JsonAdapter jsonAdapter = new JsonAdapter(map);
// 原始数据
String data = "";
List> maps = jsonAdapter.allData(data);
