可以尝试优化一下代码结构,减少嵌套层数,使得代码更加易读和易维护。例如可以将转换结构的代码抽取成一个单独的方法,用于处理每个 referencedPerMap 中的数据,并返回转换后的表格和列名以及对应的 codeList 的 Map 对象。同时,可以考虑使用 Java 8 的 Stream API,更加简洁地实现循环操作。修改后的代码如下:
```
private void addReferencedKpi(List<SimulationTableDto> list, List<String> codeList, List<Map<String, List<String>>> referencedList) {
if (CollectionUtils.isEmpty(list) || CollectionUtils.isEmpty(codeList) || CollectionUtils.isEmpty(referencedList)) {
return;
}
// 转换结构 key1-table key2-column value-codeList
Map<String, Map<String, List<String>>> tableColumnWithCodeListMap = new HashMap<>();
referencedList.forEach(referencedPerMap -> {
if (MapUtils.isEmpty(referencedPerMap)) {
return;
}
referencedPerMap.forEach((table, columns) -> {
tableColumnWithCodeListMap.computeIfAbsent(table, k -> new HashMap<>());
columns.forEach(column -> tableColumnWithCodeListMap.get(table).computeIfAbsent(column, k -> new ArrayList<>()).addAll(codeList));
});
});
list.forEach(simulationTableDto -> {
String simTableName = simulationTableDto.getTableName();
String simTitle = simulationTableDto.getColumn().getTitle();
tableColumnWithCodeListMap.computeIfPresent(simTableName, (table, columnMap) -> {
if (columnMap.containsKey(simTitle)) {
simulationTableDto.getColumn().setReferencedKpis(columnMap.get(simTitle));
}
return columnMap;
});
});
}
```
