未去重前的数据类型chooseList：
[
{
"englishName":"lyss",
"assetTypeName":"角色",
"name":"lyss",
"isSelect":0,
"id":65195
},
{
"englishName":"mkkm",
"assetTypeName":"角色",
"name":"mkkm",

"id":65194
},
{
"englishName":"asset-01",
"assetTypeName":"角色",
"name":"asset-01",
"isSelect":0,
"id":34964
},
{
"englishName":"lyss",
"assetTypeName":"角色",
"name":"lyss",
"isSelect":0,
"id":65195
},
{
"englishName":"mkkm",
"assetTypeName":"角色",

},
{
"englishName":"asset-01",

},
{

},

想得到的数据类型chooseList3：
[
{
"englishName":"lyss",
"assetTypeName":"角色",
"name":"lyss",
"isSelect":1,
"id":65195
},
{
"englishName":"mkkm",
"assetTypeName":"角色",
"name":"mkkm",
"isSelect":1,
"id":65194
},
{
"englishName":"asset-01",
"assetTypeName":"角色",
"name":"asset-01",
"isSelect":1,
"id":34964
}
]
实现步骤：
1.获取唯一的name对应的json：
通过：
for ( int i = 0 ; i < chooseList.size() - 1 ; i ++ ) {
for ( int j = chooseList.size() - 1 ; j > i; j -- ) {
if (chooseList.get(j).get("name").equals(chooseList.get(i).get("name"))) {
chooseList.remove(j);
}
}
}
得到：
[
{
"englishName":"lyss",
"assetTypeName":"角色",
"name":"lyss",
"isSelect":0,
"id":65195
},
{
"englishName":"mkkm",
"assetTypeName":"角色",
"name":"mkkm",
"isSelect":0,
"id":65194
},
{
"englishName":"asset-01",
"assetTypeName":"角色",
"name":"asset-01",
"isSelect":0,
"id":34964
}
]
2.拿获取的唯一的name对应的json和最开始的chooseList进行对比：
List<JSONObject> chooseList3= new ArrayList<>();
for(int i=0;i<chooseList.size();i++){
JSONObject map= new JSONObject();
String name = chooseList.get(i).get("name").toString();
map.put("id", chooseList.get(i).get("id"));
map.put("name", chooseList.get(i).get("name"));
map.put("englishName", chooseList.get(i).get("englishName"));
map.put("assetTypeName", chooseList.get(i).get("assetTypeName"));
chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect"));
System.out.println("=====3333=====:"+chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()));
System.out.println("======22====:"+chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect")).collect(Collectors.toList()));
if(chooseList2.stream().filter(x-> x.get("name").toString().equals(name)).collect(Collectors.toList()).stream().map(isSelect->isSelect.get("isSelect")).collect(Collectors.toList()).contains(1)){
map.put("isSelect",1);
} else{
map.put("isSelect",0);
}
chooseList3.add(map);
}
控制台输出：
