改造的是DictAspect类:
原来使用的 parseDictText(Object result)方法,针对返回对象为Result 的IPage的分页列表数据进行动态字典注入,当单个对象查询,列表查询,或者多个数据放到Map中时,就不会自动转化,在web端进行展示的时候就需要连表查询或者手动查询字典值,不方便使用。
于是我改造了parseDictText()方法,不仅针对返回对象为Result时的分页列表,还支持列表、对象以及Map类型的结果。实在Result对象执行setResult()方式时进行自动注入转换。
原方法
代码:
private Object parseDictText(Object result) {//if (result instanceof Result) {if (true) {if (((Result) result).getResult() instanceof IPage) {List<JSONObject> items = new ArrayList<>();//step.1 筛选出加了

改造
判断传递参数的类型,是IPage、List、Map、Object,如果是IPage、List、Map,则把对象中的数据拿出来再挨个转换,改造为新的结果数据返回。
