这篇博客介绍了如何将第三方接口返回的json数据利用net.sf.json.JSONObject的toBean方法，转换为Java对象。示例中展示了将jsonObject转换为ContractRoot类型的实例。

接受第三方接口返回的json数据，解析转换成Javabean 的方法。

通过 net.sf.json.JSONObject.toBean 方法转换，
ContractRoot root = (ContractRoot)net.sf.json.JSONObject.toBean(jsonObject, ContractRoot.class, classMap);

详细可参考下面例子

接受第三方接口返回的json数据，解析转换成Javabean

public class outbandUtils {
    /**
     * 接受第三方接口返回的json数据，解析转换成Javabean
     * add by linsd 20180413
     * @param jsonObject
     * @param className
     */
    public static void turnJsonTOBean(JSONObject jsonObject,String className){
        if(!jsonObject.equals(null)){
            Map<String, Object> classMap = new HashMap<String, Object>();
            classMap.put("orderItem", OrderItem.class);
            classMap.put("customer", Customer.class);
            classMap.put("accounts", Accounts.class);
            classMap.put("partyCerts", PartyCerts.class);
            classMap.put("ordProdInsts", OrdProdInsts.class);
            classMap.put("ordProdInstAttrs", OrdProdInstAttrs.class);
            classMap.put("ordServAcctRels", OrdServAcctRels.class);
            classMap.put("ordProdInstStates", OrdProdInstStates.class);
            classMap.put("mktResCardInsts", MktResCardInsts.class);
            classMap.put("mktResCardInstAttrs", MktResCardInstAttrs.class);
            classMap.put("ordProdInstRels", OrdProdInstRels.class);
            classMap.put("ordOfferInsts", OrdOfferInsts.class);
            classMap.put("ordOfferInstAttrs", OrdOfferInstAttrs.class);
            classMap.put("ordOfferProdInstRels", OrdOfferProdInstRels.class);
