如果您可以自己处理序列化对象,那么这应该可以解决问题:
import com.squareup.moshi.JsonWriter;
import com.squareup.moshi.Moshi;
import java.io.IOException;
import okio.Buffer;
public class MoshiPrettyPrintingTest {
private static class Dude {
public final String firstName = "Jeff";
public final String lastName = "Lebowski";
}
public static void main(String[] args) throws IOException {
final Moshi moshi = new Moshi.Builder().build();
final Buffer buffer = new Buffer();
final JsonWriter jsonWriter = JsonWriter.of(buffer);
// This is the important part:
// - by default this is `null`, resulting in no pretty printing
// - setting it to some value, will indent each level with this String
// NOTE: You should probably only use whitespace here...
jsonWriter.setIndent(" ");
moshi.adapter(Dude.class).toJson(jsonWriter, new Dude());
final String json = buffer.readUtf8();
System.out.println(json);
}
}
这打印:
{
"firstName": "Jeff",
"lastName": "Lebowski"
}
请参阅此测试文件和prettyPrintObject()
.BufferedSinkJsonWriter
但是,如果您将 Moshi 与 Retrofit 一起使用,我还没有弄清楚是否以及如何做到这一点。
