无法在Spring Boot中注册Gson TypeAdapter

import com.google.gson.TypeAdapter;
import com.google.gson.stream.JsonReader;
import com.google.gson.stream.JsonWriter;

public class CustomTypeAdapter extends TypeAdapter<CustomObject> {

    @Override
    public void write(JsonWriter out, CustomObject value) throws IOException {
        // 定义对象序列化规则
        // ...
    }

    @Override
    public CustomObject read(JsonReader in) throws IOException {
        // 定义对象反序列化规则
        // ...
    }
}

import com.google.gson.Gson;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class GsonConfig {

    @Bean
    public Gson gson() {
        Gson gson = new Gson();
        gson.registerTypeAdapter(CustomObject.class, new CustomTypeAdapter());
        return gson;
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class MyClass {

    @Autowired
    private Gson gson;

    public void serializeObject(CustomObject obj) {
        String json = gson.toJson(obj);
        // ...
    }

    public CustomObject deserializeObject(String json) {
        CustomObject obj = gson.fromJson(json, CustomObject.class);
        // ...
        return obj;
    }
}
