java项目获取实例化对象

检测文件编码---

public class LookupCharset {private Logger log = Logger.getLogger(getClass());/** 字符集对象 */private Charset charset = Charset.defaultCharset();/** 找到某个字符集的布尔变量 */private boolean found = false;/** * 构造方法 *  * @param file */public LookupCharset(File file) {lookup(file);}/** * 获取字符集 *  * @return */public Charset getCharset() {return charset;}/** * 查找指定文件的字符集 *  * @param file */protected void lookup(File file) {// Initalize the nsDetector() ;nsDetector det = new nsDetector(nsPSMDetector.ALL);// 语言线索常量// Set an observer...// The Notify() will be called when a matching charset is found.det.Init(new nsICharsetDetectionObserver() {// nsICharsetDetectionObserver.Notify编码识别成功后掉用public void Notify(String charsetName) {charset = Charset.forName(charsetName);found = true;}});BufferedInputStream imp = null;try {// 读取文件imp = new BufferedInputStream(new FileInputStream(file));byte[] buf = new byte[1024];int len = imp.read(buf, 0, buf.length); // 读取一个缓存区的数据boolean isAscii = det.isAscii(buf, len);// 先测试Asciiif (!isAscii) {det.DoIt(buf, buf.length, false);// 测试}det.DataEnd();// 测试结束！if (isAscii) {charset = Charset.forName("ASCII");found = true;}if (!found) {// 没找到设定一个最有可能的编码！！String prob[] = det.getProbableCharsets();charset = Charset.forName(prob[0]);}} catch (IOException e) {log.error(e);} finally {try {if (imp != null) {imp.close();}} catch (IOException e) {log.error(e);}}}}

实例：

DefaultBeanFactory.getBean("monitorService");

BundleConfig functionBundle = new BundleConfig("function");（附件jar）读取property文件
