JSON和Map的互转、xml转Map

需要引入的jar包：

1.commons-lang.jar 

2.commons-beanutils.jar

3.commons-collections.jar

4.commons-logging.jar 

5.ezmorph.jar

6.json-lib-2.2.2-jdk15.jar

具体代码如下：

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONObject;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;

public class JsonTest {

    public static void main(String[] args) throws DocumentException {

        //*******************Map 转 JSon**********************
        Document doc = DocumentHelper.parseText(getContent(
                "C:\\Documents and Settings\\wzhe\\桌面\\测试用例\\安防\\", "413.txt"));
        Map map = XmlUtils.dom2Map(doc);
        JSONObject jsobj= JSONObject.fromObject(map);
        System.out.println(jsobj.toString());

        //*******************JSON 转 Map**********************

        List tmpList= (List) tmpObj.get("BC_INFO");
        Map bcMap = (Map) tmpList.get(0);
        System.out.println(bcMap.get("FAULT_REASON").toString());
    }

    public static String getContent(String filePath, String fileName) {
        File file = new File(filePath, fileName);
        InputStream strm = null;
        StringBuffer content = new StringBuffer();
        try {
            strm = new FileInputStream(file);

            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    strm, "GBK"));
            String line = "";

                content.append(line);
            }
        } catch (Exception e1) {
            e1.printStackTrace();
