經過反射給屬性賦值代碼示例

    @Autowired
    private DictUtil dictUtil;

    public DictHelper() {
    }

                        ((Dict)dict).setCode(map.get("code"));
                        ((Dict)dict).setName(map.get("name").toString());
                    } else {
                        dict = (Dict)o;
                    }

                    setMethod.invoke(t, ((Dict)dict).getName());
                }
            }
        } catch (Exception var13) {
            String errorMsg = "爲對象設置字典錯誤\n";
            errorMsg = errorMsg + "getField：" + getField + "\n";
            errorMsg = errorMsg + "setField：" + setField + "\n";
            errorMsg = errorMsg + "設置對象的類：" + t.getClass();
            LoggerUtils.warn(errorMsg, var13);
        }

        return t;
    }
}

方法調用：

List<DriverLine> driverLineList = new ArrayList<>();
DriverLine driverLine = new DriverLine();
driverLine.setLineId(2);
driverLineList.add(driverLine);
Object o = dictHelper.loadListDict(driverLineList, "basic.line", "lineId","lineName");//basic.line
System.err.println(o.toString());
