[leroylrh]

问题描述

简要描述您碰到的问题。
数组、实体对象等非基本类型和String 作为Map.key时，开启AutoType，序列化后，如果未指定具体的目标类型，则反序列化报错

环境信息

请填写以下信息：

• OS信息： [e.g.：CentOS 8.4.2105 4Core 3.10GHz 16 GB]
• JDK信息： [e.g.：Openjdk 1.8.0_312]
• 版本信息：[e.g.：Fastjson2 2.0.61]

重现步骤

如何操作可以重现该问题：

	public void testEntityKeyEncode() {
		Map<TestKey, Object> map = new HashMap<>();
		map.put(new TestKey(1), "value1");
		map.put(new TestKey(2), "value2");
		String jsonString = JSONUtil.encode(map);
		System.out.println(jsonString);
		Object jasonObject = JSONObject.parseObject(jsonString, Object.class, Feature.AllowUnQuotedFieldNames);

		System.out.println(JSONObject.toJSONString(jasonObject));
		Object object = JSONUtil.decode(jsonString, new com.alibaba.fastjson2.TypeReference<Map<TestKey, Object>>() {
		});
		String jsonString2 = JSONUtil.toJSONString(object);
		System.out.println(jsonString2);

		Object jasonObject3 = JSONUtil.decode(jsonString, Map.class);
		String jsonString3 = JSONUtil.toJSONString(jasonObject3);
		System.out.println(jsonString3);
	}

	public void testArrayKeyEncode() {
		Map<Integer[], Object> map = new HashMap<>();
		map.put(new Integer[]{1, 2}, "value1");
		map.put(new Integer[]{3, 4}, "value2");
		String jsonString = JSONUtil.encode(map);
		System.out.println(jsonString);
		Object jasonObject = JSONObject.parseObject(jsonString, Object.class, Feature.AllowUnQuotedFieldNames);

		System.out.println(JSONObject.toJSONString(jasonObject));
		Object object = JSONUtil.decode(jsonString, new com.alibaba.fastjson2.TypeReference<Map<Integer[], Object>>() {
		});
		String jsonString2 = JSONUtil.toJSONString(object);
		System.out.println(jsonString2);

		Object jasonObject3 = JSONUtil.decode(jsonString, Map.class);
		String jsonString3 = JSONUtil.toJSONString(jasonObject3);
		System.out.println(jsonString3);
	}

	public static String encode(Object object) {
		// 要避免String类型 再次被包装
		if (object instanceof String) {
			return (String) object;
		}
		return JSONObject.toJSONString(object
				, Feature.WriteClassName
				, Feature.IgnoreErrorGetter
				, Feature.FieldBased
				, Feature.WriteNonStringKeyAsString
		);
	}

	public static <T> T decode(String s, Class<T> t) {
		s = JediStrUtil.isEmpty(s) ? null : s;
		return JSON.parseObject(s, t
				, autoTypeBeforeHandler
				, JSONReader.Feature.FieldBased
				, JSONReader.Feature.IgnoreAutoTypeNotMatch
				, JSONReader.Feature.UseNativeObject
				, JSONReader.Feature.SupportClassForName
				, JSONReader.Feature.AllowUnQuotedFieldNames
		);
    }

	public static class TestKey {
		int id;

		public TestKey(int id) {
			this.id = id;
		}
	}

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。
能够根据ClassName 正确解析成指定的对象

JSON反序列化时要添加Feature.SupportAutoType特性，2.0.62版本默认不支持带ClassNmae类型的反序列化,
正确反序列化方式代码： JSON.parseObject(str, clazz, Feature.SupportAutoType);

JSON反序列化时要添加Feature.SupportAutoType特性，2.0.62版本默认不支持带ClassNmae类型的反序列化, 正确反序列化方式代码： JSON.parseObject(str, clazz, Feature.SupportAutoType);

我用的是2.0.61版本，使用了AutoTypeBeforeHandler， Feature.SupportAutoType被声明弃用了。而且即使我添加了Feature.SupportAutoType，依然报错。我任何 核心是 非基本类型和String 作为Map.key时，toJSONString 不会将其转为String ,即使加了WriteNonStringKeyAsString，在parser时，又将其当成了String，导致报错
