接口获取财物系统数据一点想法

         因财务系统数据保密性，大数据平台无法直连，于是搭建了一个JS2E小功能，实现HTTPClient 远程访问 API接口，此功能将实现多个财务接口数据的查询。在大数据平台Shell调生成的JAR包（根据 Apache CLI 命令参数 传递参数区分不同的调用接口，类似Web多线程）。

具体一些小细节如下：

一 工具类：

 

       1.1    Base64 工具

public class Base64Util {

    final static Base64.Encoder encoder = Base64.getEncoder();
    final static Base64.Decoder decoder = Base64.getDecoder();

    public static String base64Encoder(String text) {
        return encoder.encodeToString(text.getBytes(Charset.forName("GBK")));
    }

    public static String base64Decoder(String text) {
        return new String(decoder.decode(text), Charset.forName("GBK"));
    }

}

        1.2  FastJsonUtil  工具

public class FastJsonUtil {
 
    public static String beanToJson(Object object) {
        return beanToJson(object, null);
    }

  
    public static String beanToJson(Object object, String datePattern) {

        if (ObjectUtils.isEmpty(object)) {
            return null;
        }
        String json;
        try {
            if (StringUtils.isBlank(datePattern)) {
                json = JSON.toJSONString(object);
            } else {
                json = JSON.toJSONStringWithDateFormat(object, datePattern);
            }
            return json;
        } catch (JSONException e) {
            throw new RuntimeException("对象[" + object.getClass().getName() + "]转换成JSON异常,", e);
        }

    }

}

1.3  Dom 工具  

// resultCode
public static String getResultCode(String rootXml) throws DocumentException {
    Document document = DocumentHelper.parseText(rootXml);
    Node resultCode = document.selectSingleNode("/XML_ROOT/ResultInfo/Result/@CODE");
    return resultCode.getText();
}

// po
public static String getPo(String rootXml) throws DocumentException {
    Document document = DocumentHelper.parseText(rootXml);
    Node Value0 = document.selectSingleNode("/XML_ROOT/ResultInfo/Values/Value0");
    return Base64Util.base64Decoder(Value0.getText());

}

// Node
public static Node singleNode(String rootXml, String xmlPath) throws DocumentException {
    Document document = DocumentHelper.parseText(rootXml);
    return document.selectSingleNode(xmlPath);
}

// xmlPathValue
public static List<Node> multipleNodes(String rootXml, String xmlPath) throws DocumentException {
    SAXReader reader = new SAXReader();
    Document document = DocumentHelper.parseText(rootXml);
    List<Node> nodes = document.selectNodes(xmlPath);
    return nodes;
}

1.4  JDBCUtil 工具   

String driver = PropertiesUtil.getProperty("application.datalake.oracle.driver");
String url = PropertiesUtil.getProperty("application.datalake.oracle.url");
String username = PropertiesUtil.getProperty("application.datalake.oracle.username");
String password = PropertiesUtil.getProperty("application.datalake.oracle.password");

Class.forName(driver);
Connection connection = DriverManager.getConnection(url, username, password);
return connection;

1.5    PropertiesUtil 工具

public class PropertiesUtil {

    private static Logger logger = LogManager.getLogger(PropertiesUtil.class);

    private final static Properties props = new Properties();

    static {
        try {
            props.load(PropertiesUtil.class.getClassLoader().getResourceAsStream("application-dev.properties"));
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(" PropertiesUtil 静态加载, exception=[{}]", FastJsonUtil.beanToJson(e.toString()));
        }
    }

    public static String getProperty(String key) {
        return props.getProperty(key);
    }

}
