java读取服务器XML和JSON文件

java读取服务器XML和JSON文件

java读取XML

	xml文件内容：

:

public static void main(String[] args) throws Exception {
        String filePath = "D:\\file\\javaRead.xml";
        String sMes = getXMLFileAttr(filePath);
        System.out.println("sMes:" + sMes);
    }
    public static String getXMLFileAttr(String filePath) throws Exception {
        String sRtMes = null;
        SAXReader reader = new SAXReader();
        File file = new File(filePath);
        Document document = reader.read(file);
        Element root = document.getRootElement();
        String enable = root.attributeValue("ENABLE");
        if (!StringUtils.equalsIgnoreCase("true", enable)) {
            return "error";
        }
        Element publicAttrElem = root.element("PublicAttr");
        List<Element> elements = publicAttrElem.elements("Attr");
        for (Element element : elements) {
            String sWeb = element.attributeValue("web");
            switch (sWeb) {
                case "name":
                    sRtMes = element.attributeValue("java");
                    return sRtMes;
                default:
                    sRtMes = "code";
            }
        }
        return sRtMes;
    }

输出：

java读取服务器JSON

json文件内容

代码示例：

 public static void main(String[] args) throws Exception {
        String filePath = "D:\\file\\readJson.json";
        String sJsonData = getJSONFromFile(filePath);
        JSONObject jsonData = JSON.parseObject(sJsonData);
        String attrValue = jsonData.getJSONObject("javaWeb").getJSONObject("java").getString("language");
        System.out.println("attrValue:" + attrValue);
    }

    public static String getJSONFromFile(String strJSONPath) throws Exception {
        StringBuilder bu = new StringBuilder();
        BufferedReader br = null;
        try {
            br = new BufferedReader(new FileReader(strJSONPath));// 读取原始json文件
            String s = null;
            while ((s = br.readLine()) != null) {
                try {
                    bu.append(s);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            return bu.toString();
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        } finally {
            if (null != br) {
                br.close();
            }
        }
    }
