for (SchemaRowRuleEo schemaRowRuleEo : schemaRowRuleList) { //获取行规则要素 String filterConditionList = schemaRowRuleEo.getFilterConditionList(); List<SchemaRowFilterCondition> schemaRowFilterConditions = JSONObject.parseArray(filterConditionList, SchemaRowFilterCondition.class); for (SchemaRowFilterCondition schemaRowFilterCondition : schemaRowFilterConditions) { String field = schemaRowFilterCondition.getField(); String camel = underlineToCamel(field); String key = schemaRowFilterCondition.getKey(); Field fieldsAndParentsField = fieldStream .filter(f -> StringUtils.equals(f.getName(), camel)) .findFirst() .orElseThrow(() -> new CustomException("大马猴来了", code)); Field f = object.getClass().getDeclaredField(camel); f.setAccessible(true); Object value = f.get(object); if (StringUtils.equals(key, value.toString()) && schemaRowRuleEo.getRowEditPermission()) { System.out.println("修改成功"); } else { throw new CustomException("大马猴来了", code); } } }优化这段java代码

这段 Java 代码可以做以下优化：

1. 使用 Lambda 表达式简化代码，如使用 Lambda 表达式替换 for 循环。

2. 避免重复获取对象的属性 Field，可以将其缓存到一个 Map 中，以便多次使用。

3. 将一些重复的字符串提取成常量，避免代码中出现重复的字符串。

下面是优化后的代码：

private static final String CODE = "大马猴来了";

public void optimizeCode(Object object, List<SchemaRowRuleEo> schemaRowRuleList) throws NoSuchFieldException, IllegalAccessException {
    Map<String, Field> fieldMap = Arrays.stream(object.getClass().getDeclaredFields())
            .collect(Collectors.toMap(Field::getName, field -> {
                field.setAccessible(true);
                return field;
            }));
    for (SchemaRowRuleEo schemaRowRuleEo : schemaRowRuleList) {
        String filterConditionList = schemaRowRuleEo.getFilterConditionList();
        List<SchemaRowFilterCondition> schemaRowFilterConditions = JSONObject.parseArray(filterConditionList, SchemaRowFilterCondition.class);
        for (SchemaRowFilterCondition schemaRowFilterCondition : schemaRowFilterConditions) {
            String field = schemaRowFilterCondition.getField();
            String camel = underlineToCamel(field);
            String key = schemaRowFilterCondition.getKey();
            Field fieldAndParentField = fieldMap.get(camel);
            Object value = fieldAndParentField.get(object);
            if (StringUtils.equals(key, value.toString()) && schemaRowRuleEo.getRowEditPermission()) {
                System.out.println("修改成功");
            } else {
                throw new CustomException(CODE, CODE);
            }
        }
    }
}

private static String underlineToCamel(String underline) {
    StringBuilder result = new StringBuilder();
    String[] words = StringUtils.split(underline, '_');
    for (int i = 0; i < words.length; i++) {
        String word = words[i];
        if (i == 0) {
            result.append(word);
        } else {
            result.append(StringUtils.capitalize(word));
        }
    }
    return result.toString();
