Filter in list by responseEentity in Java
问题
我需要使用响应来过滤一个列表
ResponseEntity<Group> listaGrupo = monstarListaGrupo(login, token);
List<Directory> diretorios = lista.stream()
.filter(x -> x.getGroupAd().equals(listaGrupo.getBody().getGroups()))
我尝试以这种方式去做，但是它不允许，因为它说一个类型是列表，另一个类型是字符串。
使用响应实体对年龄列表进行公寓过滤
响应实体：
{
"name": "barry",
"age": 20
},
{
"name": "allan",
"age": 17
},
{
"name": "julie",
"age": 20
},
{
"name": "jord",
"age": 19
}
列表：
{
"name": "jhenny",
"age": 20,
"color": "red"
},
{
"name": "barry",
"age": 20,
"color": "black"
},
{
"name": "julie",
"age": 20,
"color": "white"
}
最终结果列表：
{
"name": "barry",
"age": 20,
"color": "black"
},
{
"name": "julie",
"age": 20,
"color": "white"
}

I need to filter a list with a response
ResponseEntity<Gruoup> listaGrupo = monstarListaGrupo(login, token);
List<Diretorio> diretorios = lista.stream()
.filter(x-> x.getGrupoAd() == listaGrupo.getBody().getGrupos())
I tried to do it that way but he doesn't let it because it says that one type is list and another is String
Apartment filter of a RespondeEntity in an age list for exam
RespondeEntity:
{
"name": "barry",
"age": 20
},
{
"name": "allan",
"age": 17
},
{
"name": "julie",
"age": 20
},
{
"name": "jord",
"age": 19
}
List:
{
"name": "jhenny",
"age": 20,
"color": "red"
},
{
"name": "barry",
"age": 20,
"color": "black"
},
{
"name": "julie",
"age": 20,
"color": "white"
}
Result final List
{
"name": "barry",
"age": 20,
"color": "black"
},
{
"name": "julie",
"age": 20,
"color": "white"
}

您正在尝试将一个 String 与 List<Grupo> 进行比较，但似乎您想要基于响应实体中包含的 grupoAd 来进行过滤。
首先，将列表中的字符串收集到一个集合中，然后使用 contains() 进行过滤，类似这样：
ResponseEntity<Gruoup> listaGrupo = monstarListaGrupo(login, token);
Set<String> names = listaGrupo.getBody().getGrupos().stream().collect(toSet());
List<Diretorio> diretorios = lista.stream()
.filter(x -> names.contains(x.getGrupoAd()))
...
英文:
You are trying to compare a String with a List<Grupo>, but it seems you want to filter based on the response entity containing the grupoAd of the directio.
First collect the Strings from the List into a Set, then use contains() for the filter, somethingh like this:
ResponseEntity<Gruoup> listaGrupo = monstarListaGrupo(login, token);
Set<String> names = listaGrupo.getBody().getGrupos().stream().collect(toSet());
List<Diretorio> diretorios = lista.stream()
.filter(x -> names.contains(x.getGrupoAd()))
