菜鸟上路，请各位高手赐教！java读写本地json文件

[chendanook]

11． programmers.json文件中包含如下内容：
{ "programmers": [ { "firstName": "Brett", "lastName":"McLaughlin", "email": "[e-mail]" }, { "firstName": "Jason", "lastName":"Hunter", "email": "[e-mail]" }, { "firstName": "Elliotte", "lastName":"Harold", "email": "[e-mail]" } ],"authors": [ { "firstName": "Isaac", "lastName": "Asimov", "genre": "science fiction" }, { "firstName": "Tad", "lastName": "Williams", "genre": "fantasy" }, { "firstName": "Frank", "lastName": "Peretti", "genre": "christian fiction" } ],"musicians": [ { "firstName": "Eric", "lastName": "Clapton", "instrument": "guitar" }, { "firstName": "Sergei", "lastName": "Rachmaninoff", "instrument": "piano" } ]}
从文件获取programmers、authors 和 musicians的信息，做以下处理：
1. 在控制台输出Jason,Isaac,Sergei的相关信息（firstName,lastName等）
2. 将分析得到的programmers、authors 和 musicians的信息，以json格式输出到people.json文件中
3. 将programmers.json的内容转换为XML格式,根元素为data.
求该题的完整代码！新手刚入门，还请各位高手多多指教，不胜感激！

就是用file读取文件内容（应该是按行读取）

再用JSONObject解析就行了。

	private ObjectMapper mapper;

	private List<AppConfig> appConfig;

	public AppConfigController()
	{

		String propsFile = AppConfigController.class.getResource("/").toString().replace("file:", "") + "appConfig.cfg";

		this.mapper = new ObjectMapper();

		this.mapper.setAnnotationIntrospector(new NopAnnotationIntrospector());

		try
		{
			propsFile = java.net.URLDecoder.decode(propsFile,"utf-8");
			
			logger.info("获取到配置文件路径{}", new File(propsFile).getAbsolutePath());

			this.appConfig = mapper.readValue(new File(propsFile), new TypeReference<List<AppConfig>>()
			{
			});
		} catch (Exception e)
		{
			e.printStackTrace();
			logger.warn(e.getMessage() + "配置文件路径：{}", propsFile);
		}
	}

@JsonPropertyOrder({"appId","customerId","siteId","siteName","appVersion","appDownloadUrl","weiboServerAddress","aboutServerAddress","uMengAppSecret","advertServerAddress","weatherURL","contentTemplate"
	,"websiteLinks"})
public class AppConfig
{
	private int appId;
	private int customerId;
	private int siteId;
	private String siteName;
	private String appVersion;
	private String appDownloadUrl;
	private List<WeiboServerAddress> weiboServerAddress;
	
	private String aboutServerAddress;
	
	private String uMengAppSecret;
	private String advertServerAddress;
	private String weatherURL;
	private String contentTemplate;
	private List<WebSiteLink> websiteLinks;

定义的json对象，跟你文件一一对应就行
jackson 用这个处理json比较方便 你可以谷歌一下找下jar包，参考一下
