java如何将JAXB转换为JSON？

Question

我需要为返回JAXB对象的基于XML的web服务创建一个web服务前端。我的前端需要返回RESTful格式。有没有办法将其转换为JSON？在我的课堂路径中，我有jackson mapper asl和jackson core asl

作为一个简单的测试，我返回一个Book bean，它以JSON的形式输出，但JAXB对象（交付时间表）保持XML格式

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class DSWLIClient {

    @Autowired
    private DeliveryScheduleWS wliService;
    private BookService bs;

    @RequestMapping(value = "/DSDetails/{ds-number}", method = RequestMethod.GET)
    public @ResponseBody
    DeliverySchedule getDSDetails(@PathVariable("ds-number") String dsNumber) {
        DeliveryScheduleResponse dsDetails = wliService.getDeliveryScheduleWSSoap().getDSDetails(dsNumber);
        DeliverySchedule deliverySchedule = dsDetails.getDeliverySchedule();
        return deliverySchedule;
    }


    @RequestMapping(value = "/BookDetails/{isbn-number}", method = RequestMethod.GET)
    public @ResponseBody
    Book getBookDetails(@PathVariable("isbn-number") String isbnNumber) {
        bs = new BookService();
        Book b = bs.getBookByIsbn(isbnNumber);
        System.out.println(b.getAuthor());
        return b;
    }


}
