Java API, com.hankcs.hanlp.model.perceptron.PerceptronLexicalAnalyzer is not serializable.

[cumtfc]

Describe the bug
Java API, while com.hankcs.hanlp.model.perceptron.PerceptronLexicalAnalyzer.class be used as a member variable in Spark, it throws "Caused by: java.io.NotSerializableException: com.hankcs.hanlp.model.perceptron.PerceptronLexicalAnalyzer".
That is because spark try to serialize PerceptronLexicalAnalyzer , but this class didn`t implements Serializable interface.
Code to reproduce the issue

public class Test{
private final PerceptronLexicalAnalyzer analyzer;
public Test() throws IOException {
analyzer = new PerceptronLexicalAnalyzer("./cws.bin",
"./pos.bin",
"./ner.bin");
}
public static void main(String[] args) throws IOException {
Test a = new Test();
try {
FileOutputStream fileOut = new FileOutputStream("./test.ser");
ObjectOutputStream out = new ObjectOutputStream(fileOut);
out.writeObject(a);
out.close();
fileOut.close();
System.out.println("Serialized data is saved in ./test.ser");
} catch (IOException i) {
i.printStackTrace();
}
}
}

Describe the current behavior
Caused by: java.io.NotSerializableException: com.hankcs.hanlp.model.perceptron.PerceptronLexicalAnalyzer.

Expected behavior
No Exception been threw.

Hi, PerceptronLexicalAnalyzer is not meant to be serializable. You can serialize each model instead. Or, implement a serializable subclass and do serialization of models by yourself.
