以下是对代码的优化建议：

1. 将一些常量或重复使用的变量定义为常量或静态变量，避免重复创建和赋值，提高性能。

2. 在lambda表达式中使用方法引用或静态导入，使代码更加简洁。

3. 将长的if-else语句和嵌套的for循环拆分成小的方法，使代码更加可读和易于维护。

4. 使用Java 8的Stream API进行集合操作，使代码更加简洁和易于阅读。

以下是优化后的代码：

@PostMapping("/BOM/referenceDataTest") public Map<String, Object> referenceDataTest(@RequestBody String requestBody) { JSONObject params = JSON.parseObject(requestBody); List materialList = materialService.list(Wrappers.lambdaQuery() .eq(Material::getProcessId, params.getString("processId")) .orderByAsc(Material::getSerialNumber));

List<Material> oldMaterialList = materialList;
int count = params.getIntValue("count");
String country = params.getString("country");
String supplier = params.getString("supplier");

String batch = "GDZB2A38SA";
Integer version = 1;
List<NPallet> palletList = nPalletService.list(Wrappers.<NPallet>lambdaQuery()
        .select(NPallet::get托架型号)
        .eq(NPallet::get批次号, batch)
        .eq(NPallet::get关联版本, version)
        .likeRight(NPallet::get包装物料, "屏")
        .orderByAsc(NPallet::get序号));
List<String> collect = palletList.stream().map(NPallet::get托架型号).collect(Collectors.toList());
int y = NumberUtil.parseInt(StrUtil.subAfter(collect.get(0), "×", true));

List<Material> newMaterialList = oldMaterialList.stream()
        .filter(i -> checkMaterial(i, count, country, supplier))
        .collect(Collectors.toList());

Map<String, Object> result = new HashMap<>();
result.put("code", 0);
result.put("message", "操作成功");
result.put("bom", newMaterialList);
return result;

}
