它给出的输出是：

Begin object
Token KEY >>>> priceAgreementLineDetails
Begin array
Begin object
Token KEY >>>> catalogue
Begin object
Token KEY >>>> assetClassDetails
Begin array
Begin object

因此，当它遇到一个空对象时，它不会继续前进。由于这是一个无效的 json，我希望它会失败，但它会提前失败。

【解决方案1】：

您的算法以这样的方式工作，一旦您的代码到达任何END_OBJECT 令牌，它就会在您的代码中打破唯一未嵌套的while。发生这种情况是因为您的代码不处理每个特定复杂子元素（即数组和对象）的状态，因此无法将 assetClassDetails 中的第一个空对象与顶部对象端区分开来。要么使用堆栈来保存每个子元素的状态，要么使用递归：

public final class StreamReadingTest {

    @Test
    public void test()
            throws IOException {
        try ( final JsonReader jsonReader = ... ) {
            jsonReader.setLenient(true);
            read(jsonReader);
        }
    }

    private static void read(final JsonReader jsonReader)
            throws IOException {
        read(jsonReader, 0);
    }

    private static void read(final JsonReader jsonReader, final int level)
            throws IOException {
        final JsonToken token = jsonReader.peek();
        switch ( token ) {
        case BEGIN_ARRAY:
            printMessage(level, "ARRAY");
            jsonReader.beginArray();
            while ( jsonReader.hasNext() ) {
                read(jsonReader, level + 1);
            }
            jsonReader.endArray();
            break;
        case END_ARRAY:
            throw new AssertionError();
        case BEGIN_OBJECT:
            printMessage(level, "OBJECT");
            jsonReader.beginObject();
            while ( jsonReader.hasNext() ) {
                printMessage(level, "| NAME = " + jsonReader.nextName());
                read(jsonReader, level + 1);
            }
            jsonReader.endObject();
            break;
        case END_OBJECT:
            throw new AssertionError();
        case NAME:
            throw new AssertionError();
        case STRING:
            printMessage(level, "STRING " + jsonReader.nextString());
            break;
        case NUMBER:
            printMessage(level, "NUMBER " + jsonReader.nextString()); // reading a string for not losing a precision
            break;
        case BOOLEAN:
            printMessage(level, "BOOLEAN " + jsonReader.nextBoolean());
            break;
        case NULL:
            jsonReader.nextNull();
            printMessage(level, "NULL");
            break;
        case END_DOCUMENT:
            printMessage(level, "END");
            break;
        default:
            throw new AssertionError(token);
        }
    }

    private static void printMessage(final int level, final String message) {
        for ( int i = 0; i < level; i++ ) {
            System.out.print("    ");
        }
        System.out.println(message);
    }

}

一旦运行，它就会打印：

OBJECT
| NAME = priceAgreementLineDetails
    ARRAY
        OBJECT
        | NAME = catalogue
            OBJECT
            | NAME = assetClassDetails
                ARRAY
                    OBJECT
            | NAME = assetClassRequired
                NULL
            | NAME = baseUnitofMeasure
                STRING PMI
            | NAME = bomParent
                STRING Yes
            | NAME = commodityCodeTaric
                STRING 84158200
            | NAME = enLanguageKey
                STRING EN
            | NAME = enMaterialLongText
                STRING Lenovo Privacy Filter for 14

和

com.google.gson.stream.MalformedJsonException: Unterminated object at line 1 column 246 path $.priceAgreementLineDetails[0].catalogue.enMaterialLongText

因为 JSON 无效。

【讨论】：

这肯定行得通。但我也在尝试修复无效的 json，这是问题的另一个方面。有什么想法吗？
@SubhenduMahanta 恐怕 Gson 和所有其他 JSON 库无法帮助您，因为任何 JSON 文档都必须有效才能被解析（通常适用于任何语法）。您可能想尝试扩展这些库以放松 JSON 规则，但我建议您尽可能获取有效的 JSON。
