fastjson2 [BUG] Dubbo 使用 Fastjson2.0.57 版本时提示 not support none-Serializable

问题描述

如下代码所示，Dubbo 使用 Fastjson 2.0.57 版本时提示报错：not support none-Serializable。使用 Fastjson 2.0.56 及之前版本则一切正常。

环境信息

请填写以下信息：

OS信息： Windows 10
JDK信息：OpenJDK 17.0.14
版本信息：Fastjson 2.0.57

重现步骤

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
static class Message<T> implements Serializable {

	T msg;

}

@Test
public void test() {
	Message<String> obj = new Message<>("Hello");
	byte[] bytes = JSONB.toBytes(obj, JSONWriter.Feature.WriteClassName,
			JSONWriter.Feature.FieldBased,
			JSONWriter.Feature.ErrorOnNoneSerializable,
			JSONWriter.Feature.ReferenceDetection,
			JSONWriter.Feature.WriteNulls,
			JSONWriter.Feature.NotWriteDefaultValue,
			JSONWriter.Feature.NotWriteHashMapArrayListClassName,
			JSONWriter.Feature.WriteNameAsSymbol);
	ContextAutoTypeBeforeHandler handler = new ContextAutoTypeBeforeHandler(true, obj.getClass());
	Object result = JSONB.parseObject(bytes, obj.getClass(), handler,
			JSONReader.Feature.UseDefaultConstructorAsPossible,
			JSONReader.Feature.ErrorOnNoneSerializable,
			JSONReader.Feature.IgnoreAutoTypeNotMatch,
			JSONReader.Feature.UseNativeObject,
			JSONReader.Feature.FieldBased);
}

期待的正确结果

一切正常

相关日志输出

com.alibaba.fastjson2.JSONException: not support none-Serializable

附加信息

如果将泛型 <T> 声明改为 <T extends Serializable>，就能够恢复正常。

dubbo调用出现RemotingException，provider端无异常，接口response带泛型，应该是一个问题 fastjson2 2.0.57 dubbo 3.2.9 cause: org.apache.dubbo.remoting.RemotingException: java.io.IOException: org.apache.dubbo.common.serialize.SerializationException: com.alibaba.fastjson2.JSONException: not support none-Serializable java.io.IOException: org.apache.dubbo.common.serialize.SerializationException: com.alibaba.fastjson2.JSONException: not support none-Serializable

@wenshao 看了下fix的代码，非包装类在对应的场景中还是会出现“not support none-Serializable”

Apr 24 '25 06:04 Razor0719

@Razor0719 因为配置了ErrorOnNoneSerializable，这里更严格一下会更安全，因为这里的T确实是限定在Serializable，按理来说，应该是全部报错才更合适的。

https://oss.sonatype.org/content/repositories/snapshots/com/alibaba/fastjson2/fastjson2/2.0.58-SNAPSHOT/ 问题已修复，请帮忙用2.0.58-SNAPSHOT版本验证

传参带泛型还是不行 [2.0.58-SNAPSHOT 这个版本还是不能用

已升级2.0.58，经过测试，依旧报错，只能回退2.0.56

Jul 31 '25 03:07 ChinaJeckXu

@wenshao 同使用2.0.58仍然遇到这个报错，请问2.0.59会修复该问题吗？

我目前已降级到2.0.56，生产环境经不起这么玩

看起来是一个严重问题，能帮忙构造重现问题的testcase，如果能够重现，我会快速修复并且发布新版本

我这边的case是这样的服务端 CommonResult定义： @Data @NoArgsConstructor public class CommonResult<T> implements Serializable { private int code; private String message; private T data; }

提供dubbo接口：CommonResult<TestDTO> testMethod(TestReq req);

客户端 dubbo 3.2.11 fastjson 2.0.58，调用该接口报错 not support none-Serializable

我这里的原因是实体类 boolean为true时，会反序列化失败，版本 2.0.59

public class NoneSerializableTest {

@Setter
@Getter
public static class ParentTestOrder implements Serializable {
    private static final long serialVersionUID = 721230004160956721L;
    private boolean flag ;
}

@Setter
@Getter
public static class TestOrder extends ParentTestOrder {
    private String name;
}

@Test
public void doTest() {
    TestOrder order = new TestOrder();
    order.setName("test");
    order.setFlag(true);

    byte[] bytes1 = JSONB.toBytes(
            order,
            JSONWriter.Feature.WriteClassName,
            JSONWriter.Feature.FieldBased,
            JSONWriter.Feature.ErrorOnNoneSerializable,
            JSONWriter.Feature.ReferenceDetection,
            JSONWriter.Feature.WriteNulls,
            JSONWriter.Feature.NotWriteDefaultValue,
            JSONWriter.Feature.NotWriteHashMapArrayListClassName,
            JSONWriter.Feature.WriteNameAsSymbol);
    JSONB.parseObject(
            bytes1,
            TestOrder.class,
            JSONReader.Feature.UseDefaultConstructorAsPossible,
            JSONReader.Feature.ErrorOnNoneSerializable,
            JSONReader.Feature.IgnoreAutoTypeNotMatch,
            JSONReader.Feature.UseNativeObject,
            JSONReader.Feature.FieldBased);
}

}

运行提示： com.alibaba.fastjson2.JSONException: not support none-Serializable

只要 order.setFlag(false); 设置为false是，就不会报错
