我正在拆分一个 Json 文件并将每个 Json 对象写入一个单独的文件，但我想将每个拆分的 Json 对象保存到一个字符串对象。不知道该怎么做。
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.nio.charset.StandardCharsets;
import org.json.JSONArray;
import org.json.JSONObject;
import org.json.JSONTokener;
public class TweetTestStack {
public static void main(String[] args) throws Exception {
String filePath = "/home/system5/Videos/Main.json";
try (
//BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(is)))
BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), StandardCharsets.UTF_8))){
// BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), "UTF-8"))) {
JSONTokener tokener = new JSONTokener(reader);
JSONArray a = new JSONArray(tokener);
for (int i = 0; i < a.length(); ++i) {
flushFile((JSONObject) a.get(0), i);
}
}
}
public static void flushFile(JSONObject obj, int d) throws Exception {
try (FileOutputStream output = new FileOutputStream("/home/system5/Music/obj-" + d + ".json");
Writer writer = new OutputStreamWriter(output, "UTF-8")) {
obj.write(writer);
}
}

最佳答案
只是一个小错误，把0改成i就可以了；(分文件没有发现重复)
for (int i = 0; i < a.length(); ++i) {
flushFile((JSONObject) a.get(i), i);
并将每个分割的 json 保存在一个字符串中:执行以下从 void 刷新为 String 的更改。
public static String flushFile(JSONObject obj, int d) throws Exception {
String s=obj.toString();
return s; }
关于java - 如何将json输出保存到String对象中，所有拆分后的文件都写入了重复数据？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35028982/
