Arrays 通过Moshi转换为Json的嵌套数组解析
我有一个这种格式的JSON字符串Arrays 通过Moshi转换为Json的嵌套数组解析,arrays,json,parsing,moshi,Arrays,Json,Parsing,Moshi,我有一个这种格式的JSON字符串 { "user": "sam", "password": "abcd1234", "categories": [ { "fruit name": "watermelon" }, { "fruit name":"jackfruit" }, { "fruit name": "kiwi" } ], "store":"S
{
"user": "sam",
"password": "abcd1234",
"categories":
[
{
"fruit name": "watermelon"
},
{
"fruit name":"jackfruit"
},
{
"fruit name": "kiwi"
}
],
"store":"SPROUTS"
}
我在想我创建了一个这样的结构类
class Structure {
String user;
String password;
String store;
private Structure() {
this.user = "sam";
this.password = "abcd1234";
this.store = "SPROUTS";
}
}
要解析JSON,我只需通过Moshi通过以下代码行即可:
Moshi moshi = new Moshi.Builder().build();
Structure structure = new Structure();
String json = moshi.adapter(Structure.class).indent(" ").toJson(structure);
但是,我还想将给定JSON中的类别传递到这个函数中。如何使用具有相同代码的类别?另外,需要对我的类结构进行哪些修改?使用Java类来表示类别JSON对象,就像您对结构JSON对象所做的那样
public final class Structure {
public final String user;
public final String password;
public final String store;
public final List<Category> categories;
Structure(String user, String password, String store, List<Category> categories) {
this.user = user;
this.password = password;
this.store = store;
this.categories = categories;
}
public static final class Category {
@Json(name = "fruit name") public final String fruitName;
Category(String fruitName) {
this.fruitName = fruitName;
}
}
public static void main(String[] args) throws Exception {
Moshi moshi = new Moshi.Builder().build();
JsonAdapter<Structure> adapter = moshi.adapter(Structure.class);
String json = "{\n"
+ " \"user\": \"sam\",\n"
+ " \"password\": \"abcd1234\",\n"
+ " \"categories\":\n"
+ " [\n"
+ " {\n"
+ " \"fruit name\": \"watermelon\"\n"
+ " },\n"
+ " {\n"
+ " \"fruit name\":\"jackfruit\"\n"
+ " },\n"
+ " {\n"
+ " \"fruit name\": \"kiwi\"\n"
+ " }\n"
+ " ],\n"
+ " \"store\":\"SPROUTS\"\n"
+ "}";
Structure value = adapter.fromJson(json);
}
}
公共最终类结构{
公共最终字符串用户;
公共最终字符串密码;
公共最终字符串存储;
公开最终名单类别;
结构(字符串用户、字符串密码、字符串存储、列表类别){
this.user=用户;
this.password=密码;
this.store=商店;
这个。类别=类别;
}
公共静态最终类类别{
@Json(name=“fruit name”)公共最终字符串fruit name;
类别(字符串名称){
this.fruthName=fruthName;
}
}
公共静态void main(字符串[]args)引发异常{
Moshi-Moshi=新的Moshi.Builder().build();
JsonAdapter adapter=moshi.adapter(Structure.class);
字符串json=“{\n”

非常感谢@Eric Cochran。实际上我自己也做了类似的事情。忘记更新这里的评论:).class Structure{String user;String password;String store;List Categories;private Structure(){this.user=“sam”;this.password=“abcd1234”;this.store=“SPROUTS”;this.Categories=新类别(“香蕉”)}私有类类别{String fruitName;私有类别(String fruit){fruit name=fruit;}
