QUESTION

How to transform this piece of code using Java Stream

Asked 2021-Sep-20 at 11:22

In order to defend against XSS attacks, I wrote a class that extends from HttpServletRequestWrapper and overrides the getParameterValues method, the code is shown below:

    @Override
    public Map<String, String[]> getParameterMap() {
        Map<String, String[]> parameters = super.getParameterMap();
        LinkedHashMap<String, String[]> map = new LinkedHashMap<>();
        if (parameters != null) {
            for (String key : parameters.keySet()) {
                String[] values = parameters.get(key);
                for (int i = 0; i < values.length; i++) {
                    String value = values[i];
                    if (!StrUtil.hasEmpty(value)) {
                        value = HtmlUtil.filter(value);
                    }
                    values[i] = value;
                }
                map.put(key, values);
            }
        }
        return map;
    }

I'm wondering if this piece of code could be transformed using Java Stream because I see a lot of if condition judgement and for loop. Methods:StrUtil.hasEmpty and HtmlUtil.filter are come from here: Hutool

Any suggestions to improve the performance of this code are welcome.

    @Override

        Map<String, String[]> parameters = super.getParameterMap();
        LinkedHashMap<String, String[]> map = new LinkedHashMap<>();
        if (parameters != null) {
            map = parameters.entrySet().stream().collect(Collectors.toMap(
                    Map.Entry::getKey,
                    v -> Arrays.stream(v.getValue())
                            .filter(val -> !StrUtil.hasEmpty(val))
                            .map(HtmlUtil::filter).collect(Collectors.toList()).toArray(new String[0]),
                    (x, y) -> y, LinkedHashMap::new
            ));
        }
        return map;
    }

Vulnerabilities

The unzip function in ZipUtil.java in Hutool before 4.1.12 allows remote attackers to overwrite arbitrary files via directory traversal sequences in a filename within a ZIP archive.
