修改一个返回值

修改前：

String saleBrandstr = "";
List<DealerInfo.SaleBrand> saleBrandList = Lists.newArrayList();
try{
saleBrandstr = "{"saleBrand":" + saleBrand + "}";
} catch (Exception ex) {
ex;
}
return saleBrandstr;

修改后：
String saleBrandstr = "";
List<DealerInfo.SaleBrand> saleBrandList = Lists.newArrayList();
try{
if (dealerType == 2 || dealerType == 1) {
if (pamra.equals("")) {
return saleBrandstr；
}
}
saleBrandstr = "{"saleBrand":" + saleBrand + "}";
DealerInfo saleBrandVo = JSONObject.parseObject(saleBrandstr, DealerInfo.class);
saleBrandList = saleBrandVo.getSaleBrand();
} catch (Exception ex) {
ex;
}
return saleBrandstr;

这样改之后是不是返回结果就变了。
