如何在struts2中使用字段名称获取json响应

Question

我在struts2中编写了一个json返回操作，它成功返回了值，我得到了如下响应

[[455,2,193,100.0,150],[459,1,193,45.0,67]]

但我需要以{{ 'id','455','inventory_id','2','doctor_id','193','price','100.0','credit','150'},{..}}来获取响应'id','455','inventory_id','2','doctor_id','193','price','100.0','credit','150'},{..}}

像这样。 那就是我想返回具有对应字段名称的json值，以便我可以轻松地对其进行迭代。 任何人都可以帮助我实现这一目标。

我正在使用休眠从数据库访问数据库。

这是我的动作课

public class DoctorEcommerceWidgets extends ActionSupport {
    private String encryptId;
    private List<DoctorToProducts> listdoctorProducts;
    private int numberOfRowsPerPage;
    private int totalNumberOfRows;
    private int lastRows;
    private int pageNum;

    public String getEcommerceWidgetFour(){ 
        try{            
            Doctor DtObj = null;
            Map sessionSingleDoctor = ActionContext.getContext().getSession();
            Object Obj = null;
            Obj = sessionSingleDoctor.get("Doctor");
            DtObj = (Doctor) Obj;
            int totalCount = DoctorDao.getInstance().totalNumberOfdoctorToProducts(DtObj.getId());
            numberOfRowsPerPage = Integer.parseInt(getText("ecommerce.widget.product.list.four"));
            totalNumberOfRows = (int)Math.ceil((float)totalCount/numberOfRowsPerPage);
            if(pageNum < 1){
                pageNum = 1;
            }else if(pageNum > lastRows){
                pageNum = lastRows;
            }
            listdoctorProducts = DoctorDao.getInstance().getDoctorProducts(DtObj.getId(),numberOfRowsPerPage,pageNum);



        }catch(Exception e){
            e.printStackTrace();
        }

        return SUCCESS;
    }

    public String getEncryptId() {
        return encryptId;
    }

    public void setEncryptId(String encryptId) {
        this.encryptId = encryptId;
    }

    public List<DoctorToProducts> getListdoctorProducts() {
        return listdoctorProducts;
    }

    public void setListdoctorProducts(List<DoctorToProducts> listdoctorProducts) {
        this.listdoctorProducts = listdoctorProducts;
    }

    public int getLastRows() {
        return lastRows;
    }

    public void setLastRows(int lastRows) {
        this.lastRows = lastRows;
    }

    public int getNumberOfRowsPerPage() {
        return numberOfRowsPerPage;
    }

    public void setNumberOfRowsPerPage(int numberOfRowsPerPage) {
        this.numberOfRowsPerPage = numberOfRowsPerPage;
    }

    public int getTotalNumberOfRows() {
        return totalNumberOfRows;
    }

    public void setTotalNumberOfRows(int totalNumberOfRows) {
        this.totalNumberOfRows = totalNumberOfRows;
    } 

}

请删除

<param name="root" >listdoctorProducts</param>
<param name="prettyPrint" >true</param>

从struts.xml中，您会发现
