java本地增量打包工具

在打增量包每次都需要将class文件、jsp文件等拷贝到增量包中比较麻烦。所以就写了一个增量打包工具。

工作原理：根据文件的最后修改时间来打增量。

1、查找Java类增量：根据eclipse工程下的.classpath文件中配置的javasrc目录，来查找修改的java文件，然后将其class文件拷贝到增量目录下。

2、查找jsp文件、配置文件，可以自定义配置。

下面为代码：

XmlReadUtil

package com.aspire.bdc.common.utils;



import java.io.File;

import java.util.ArrayList;

import java.util.List;

import java.util.Properties;



import org.apache.commons.configuration.ConfigurationException;

import org.apache.commons.configuration.XMLConfiguration;

import org.apache.log4j.Logger;



/**

* This class is used to parse an xml configuration file and return specified value.

*/

public final class XmlReadUtil {

   

    private static final String KEY_CONNECTOR = ".";

   

    private static final String DATA_FILE_NAME = System.getProperty("user.dir") + "/.classpath";

   

    private static final Logger LOGGER = Logger.getLogger(XmlReadUtil.class);

   

    private static XmlReadUtil instance;

   

    private XMLConfiguration xmlConfig;

   

    private XmlReadUtil() {

        try {

            xmlConfig = new XMLConfiguration(DATA_FILE_NAME);

        } catch (ConfigurationException e) {

            LOGGER.error(e);

            throw new RuntimeException(e);

        }

    }

   



   



    public static XmlReadUtil getInstance() {

        if (instance == null) {

            instance = new XmlReadUtil();

        }

        return instance;

    }

   

    @SuppressWarnings("rawtypes")

    public List<String> getClasspathEntry() {

        List lstSrc = xmlConfig.getList("classpathentry[@kind]");

        List listPath = xmlConfig.getList("classpathentry[@path]");

        List<String> listResult = new ArrayList<String>();

        if (listPath != null && !listPath.isEmpty()) {

            for (int i = 0; i < listPath.size(); i++) {

                if (lstSrc.get(i).equals("src")) {

                    listResult.add(System.getProperty("user.dir") + File.separator + listPath.get(i));

                }

            }

        }

        return listResult;

    }

   

}
