Answer 2

public void init() {
Map map = taxDiskInfoQueryService.findSysParam("TAXPARAMETERS");
String interfaceType = "";
String objectParam = "";
List<TaxDict> objList = taxDiskInfoQueryService.findCodeDictionaryList("TAXPARAMETERS", map.get("SELECTED_VALUE").toString());
for (TaxDict taxDict : objList) {
interfaceType = taxDict.getCode_name();
objectParam = taxDict.getCode_type_desc();
if (StringUtils.isEmpty(objectParam)) {
objectParam = "";
}
}
InterfaceType.interfaceType = interfaceType;
InterfaceType.objectParam = objectParam;
}

Answer 3

Answer 9

碰到错误，先看最后一个，nullPoint,空指针，就是调用对象的方法时，该对象是null，就会报这个错
