Begin array
Begin object

所以当它遇到一个空对象时，它就不再前进了。因为这是一个无效的json，我希望它会失败，但它失败得太早了。

您的算法的工作方式是，一旦代码到达ANY END_OBJECT标记，它就会分离出代码中唯一的非嵌套while。（即数组和对象），因此，assetClassDetails中的第一个空对象不能与顶部对象末端区分开。使用堆栈来保存每个子元素的状态，或者使用递归：

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);
    }

}

运行后，将打印：

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是无效的。
