Java泛型-需要在对象映射器中泛化A.class

Question

I have a method which maps JSON to Java class.

mapper.readValue(messageQueue, MessageQueue.class);

I need to use generics such that I can pass classname in method call so that the parsing method can be made generic rather than tighlty coupled. Something like maybe:

mapper.readValue(messageQueue, Class<T>.class);

Answer 1

You can do it like this.

public <T> T deserialize(String message, Class<T> tClass) throws IOException {
    return mapper.readValue(message, tClass);

}
