ObjectMapper mapper = new ObjectMapper();
       JsonNode jsonObj = null;
       List<ButtonBean> blist = null;
       List<TabConfig> tlist = null;
       String json = "";
       Map<String, List<WFBizForm>> map1 = new HashMap<String, List<WFBizForm>>();
       try {
           if(!StringUtil.isNullOrBlank(str)){
               json = URLDecoder.decode(str, "UTF-8");
           }
           jsonObj = mapper.readTree(json);
           JsonNode bizFromNode = jsonObj.get("businessComponent");
           BPSBizForm form = mapper.treeToValue(bizFromNode, BPSBizForm.class);
           blist = form.getButtons();
           tlist = form.getTabconfig();

public class BPSBizForm {
	private List<ButtonBean> buttons;
	private List<TabConfig> tabconfig;
}
