使用映射类的Put方法(对指定的参数使用setter)-Spring引导API

Question

我试图对所有参数只使用一个函数来对对象发出PUT请求。假设我有这样的对象结构(JSON(：

{
"id": 3,
"name": "test",
"dominio": "dom",
"altas": "6",
"bajas": "2",
"default_group": [
{
"idRef": 1,
"name": "Users",
"path": "OU=es"
}
],
"office": [
{
"idRef": 1,
"title": "Intern",
"name": "CN=Office license",
"path": "OU=licenseOffice"
},
{
"idRef": 2,
"title": "Specialist",
"name": "CN=Office License F3",
"path": "OU=LicenseGroupF"
}
]
}

我使用Map函数和类的getter为GET请求完成了这一操作。

为此，我在HTTP请求中使用GET请求传递了属性名称：

Map<String, Function<Compania, Object>> mapCompania = Map.of(
"name", Compania::getName,
"dominio", Compania::getDominio,
"altas", Compania::getAltas,
"bajas", Compania::getBajas,
"default_group", Compania::getDefault_group,
"office", Compania::getOffice
);
Function<Compania, Object> retriever = mapCompania.get(fieldName);

但现在，除了使用setter方法之外，我找不到实现同样事情的方法。类似于：

PUTlocalhost/myClass/3/name-->它使用MyClass.setName(input…(

或者：

PUTlocalhost/myClass/3/office-->它使用MyClass.setOffice(对象办公室(

有人能帮我实现这一点吗？非常感谢

假设Compania如下：

public class Compania {
private Object name;
private Object dominio;
private Object altas;
private Object bajas;
private Object default_group;
private Object office;
public Object getName() {
return name;
}
public void setName(Object name) {
this.name = name;
}
public Object getDominio() {
return dominio;
}
public void setDominio(Object dominio) {
this.dominio = dominio;
}
public Object getAltas() {
return altas;
}
public void setAltas(Object altas) {
this.altas = altas;
}
public Object getBajas() {
return bajas;
}
public void setBajas(Object bajas) {
this.bajas = bajas;
}
public Object getDefault_group() {
return default_group;
}
public void setDefault_group(Object default_group) {
this.default_group = default_group;
}
public Object getOffice() {
return office;
}
public void setOffice(Object office) {
this.office = office;
}
}

下面的代码应该可以做到这一点：

Map<String, BiConsumer<Compania, Object>> mapCompaniaSetters = Map.of(
"name", Compania::setName,
"dominio", Compania::setDominio,
"altas", Compania::setAltas,
"bajas", Compania::setBajas,
"default_group", Compania::setDefault_group,
"office", Compania::setOffice
);
BiConsumer<Compania, Object> setter = mapCompaniaSetters.get(fieldName);

我们可以如下测试，以检查它是否真的有效：

public static void main(String[] args) {
Map<String, BiConsumer<Compania, Object>> mapCompaniaSetters = Map.of(
"name", Compania::setName,
"dominio", Compania::setDominio,
"altas", Compania::setAltas,
"bajas", Compania::setBajas,
"default_group", Compania::setDefault_group,
"office", Compania::setOffice
);
BiConsumer<Compania, Object> setter = mapCompaniaSetters.get("name");
Compania compania = new Compania();
System.out.println("Empty Compania: " + compania);
setter.accept(compania, "Test");
System.out.println("Compania with Name: " + compania);
}
