如何获取数据列表作为JSON字符串

Question

内部列表并不返回一个JSON字符串..只有第一个数据表是回报...

有没有办法让所有的数据作为JSON字符串？

------我的方法---------------------

@RequestMapping(value="/mainreservationChart", method = RequestMethod.GET) 
public ModelAndView getMRChartData(@ModelAttribute ("ReservationSummaryRQDTO") ReservationSummaryRQDTO search){ 

    ReservationSummaryDTO returnDataDTO = new ReservationSummaryDTO(); 

    MainReservationChartWSImpl wsImpl = MRWSUtil.getInstance().getWS_ServicePort(); 

    search.setHotelCode("BBH"); 
    search.setReportDate(toXmlDateGMT(new Date())); 

    returnDataDTO = wsImpl.getReservationSummary(search); 

    Map<String, Object> model = new HashMap<String, Object>(); 
    model.put("status", true); 
    model.put("hotelCode", returnDataDTO.getHotelCode()); 
    model.put("summary", returnDataDTO.getSummaryMonth()); 
    model.put("data", returnDataDTO); 

    return new ModelAndView("jsonView", model); 

}

的DTO

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "reservationSummaryDTO", propOrder = { 
    "hotelCode", 
    "summaryMonth" 
}) 
public class ReservationSummaryDTO { 

    protected String hotelCode; 
    @XmlElement(nillable = true) 
    protected List<SummaryMonthDTO> summaryMonth; 
} 

---

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "summaryMonthDTO", propOrder = { 
    "month", 
    "summaryType" 
}) 
public class SummaryMonthDTO { 

    protected String month; 
    @XmlElement(nillable = false) 
    protected List<SummaryTypeDTO> summaryType; 
} 

---

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "summaryTypeDTO", propOrder = { 
    "date", 
    "displaySequence", 
    "total", 
    "typeCode" 
}) 
public class SummaryTypeDTO { 

    @XmlElement(nillable = true) 
    protected List<SummaryDateDTO> date; 
    protected Integer displaySequence; 
    protected Double total; 
    protected String typeCode;
