数据转换

1.定义数据转换接口,通过泛型实现

Converter.java

public interface Converter<IN, OUT> {

    OUT convert(IN in);
}

2.定义实现类,对指定类型转换为另一种指定类型

将ConsumerRecord<String, String>类型转换为Record类型

public class RecordConverter implements Converter<ConsumerRecord<String, String>, Record> {

    @Override
    public Record convert(ConsumerRecord<String, String> record) {
        
    }
}
