Question

我已更新到jackson-databind 2.6.0以修复反序列化错误。但是，现在我收到一个新版本（我使用版本2.4.0和2.5.4检查了相同的测试，两者都有效）。

以下是例外：

测试很简单：

@Test
    public void testOneTimeCustomer() throws Exception {
        OneTimeCustomerDTO customer = new OneTimeCustomerDTO("Max", null, null, null, null, null, null, null);
        ObjectMapper om = new MyObjectMapper();
        String result = om.writeValueAsString(customer);
        System.out.println("Result:" + result);
        om.readValue(result, OneTimeCustomerDTO.class);
    }

and has this output: Result:{"@id":1,"firstName":"Max"}

类MyObjectMapper做了一些我一直使用的配置。配置设置为：

this.setVisibility(
                getSerializationConfig().
                getDefaultVisibilityChecker().
                withFieldVisibility(JsonAutoDetect.Visibility.ANY).
                withGetterVisibility(JsonAutoDetect.Visibility.NONE).
                withSetterVisibility(JsonAutoDetect.Visibility.NONE).
                withCreatorVisibility(JsonAutoDetect.Visibility.NONE).
                withIsGetterVisibility(JsonAutoDetect.Visibility.NONE));
        this.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        this.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        this.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);

        this.setSerializationInclusion(Include.NON_NULL);

我有一个AnnotationIntrospector，它为递归结构添加了id：

@Override
    public ObjectIdInfo findObjectIdInfo(final Annotated ann) {
        if (BaseDTO.class.isAssignableFrom(ann.getRawType())) {
            // this is needed for recursive structures
            return new ObjectIdInfo(PropertyName.construct("@id", null),
                    ann.getRawType(),
                    ObjectIdGenerators.IntSequenceGenerator.class, null);
        }
        return super.findObjectIdInfo(ann);
    }

我的DTO看起来像这样： OneTimeCustomerDTO-＆GT; CustomerDTO（摘要） - ＆GT; BaseDTO（摘要）

OneTimeCustomerDTO有8个String属性，CustomerDTO 1 String和1个long属性。两者都有复杂的属性（其他类），但在测试期间它们为空，所以我认为它们不相关。

如果我删除ObjectIdInfo它也适用于2.6.0 ...但我需要这个来传递递归结构。

所以我的问题是：

有任何解决方法吗？
我没有找到报告的可能性 jackson-databind的错误？！因为我相信这是一个错误和所有应该工作得很好......

提前感谢您的时间和精力。

使用2.6.1版。这是2.6.0中的错误

Jackson-Databind ArrayIndexOutOfBoundException版本2.6.0
