Question

我使用ByteArraySerializer创建了一个自定义序列化类，如下所示。

public class ProgramListSerializer implements ByteArraySerializer<List<Program>> {
public static final TypeReference<List<Program>> LIST_PROGRAM_TYPE = new TypeReference<List<Program>>() {};

private ObjectMapper mapper = new ObjectMapper(new SmileFactory());

public ProgramListSerializer() {
}

public int getTypeId() {
    return 1001;
}

public byte[] write(List<Program> object) throws IOException {
    return this.mapper.writeValueAsBytes(object);
}

public List<Program> read(byte[] buffer) throws IOException {
    return this.mapper.readValue(buffer, LIST_PROGRAM_TYPE);
}

public void destroy() {
}}

现在我需要在hazelcast-client.xml中进行配置。我尝试定义如下。

<serialization>
<serializers>
  <serializer class-name="com.XXX.serializer.ProgramListSerailizer" type-class="java.util.List&lt;com.xxx.Program&gt;"/>
</serializers>

Hazelcast无法识别课程。引起原因：com.hazelcast.nio.serialization.HazelcastSerializationException：java.lang.ClassNotFoundException：java.util.List

有没有办法在hazelcast-client.xml中为具有泛型的collection（List，Set）定义类型类？

Answer 1

如果不测试定义是否可以正确加载，则可以通过正确转义“ <”和“>”字符来修正定义：

“ <” =“ <” “>” =“>”

例如：

type-class =“ java.util.List ”

Answer 2

抱歉，转义字符正确呈现，应该是

"&lt;" = "<"
"&gt;" = ">"

如何在hazelcast-client.xml中配置List <！-？->类型以自定义字节数组序列化
