Java配置文件的使用、加载

标签：java配置文件的使用加载

需求及背景1：在Web|Service中通常会配置自己的服务地址，加入某一个配置文件中配置了一个地址，那怎么读取这个地址。

例如：文件wsaddress.properites下的服务配置地址：address=http://127.0.0.1:8080/realware/services/AsspFinanceService,500000,2015

业务逻辑中需要得到地址：String address = WSClientHander.getDefaultAddress();

getDefaultAddress()实现：

private static String getDefaultAddress() {
		String str = null;
		if (str != null)
			return DEFAULT_ADDRESS;
		InputStream in = null;
		Properties prop = new Properties();
		try {
			in = WSClientHander.class
					.getResourceAsStream("/wsaddress.properites");
			prop.load(in);
		} catch (Exception e) {
			throw new RuntimeException(WSClientHander.PBCS035, e);
		} finally {
			if (in != null)
				try {
					in.close();
				} catch (IOException e) {
					throw new RuntimeException(WSClientHander.PBCS036, e);
				}
		}
		str = prop.getProperty("address");
		String[] array = str.split(",");
		DEFAULT_ADDRESS = array[0];
		admDivCode = array[1];
		stYear = Integer.parseInt(array[2]);
		if (null == DEFAULT_ADDRESS || DEFAULT_ADDRESS.length() == 0)
			throw new RuntimeException(WSClientHander.PBCS031);
		return DEFAULT_ADDRESS;
	}

怎么从配置文件中获取需要的配置

1）导入配置文件获得配置文件的实例evoucherConfPro  2）通过HashMap存储好我们需要的配置的Key，写死的，我们只需要些配置  3）通过getEVConfValue获得需要的配置

public class PropertiesHander {

	private static final Logger logger = Logger
			.getLogger(PropertiesHander.class);
	private static HashMap<String, String> File_MAPPINGS = new HashMap<String, String>();

	private static final Properties evoucherConfPro = PropertiesHander
			.getProByCustomPath("/", BIZConstant.FILE_NAME_EVOUCHER_CONF);

	static {
		// 注册类字段与配置字段的映射关系
		File_MAPPINGS.put("M_SIGN_SERVICE", "evoucher.model.SignService");
		File_MAPPINGS.put("M_MESSAGE_SERVICE", "evoucher.model.MessageService");
		File_MAPPINGS.put("M_ESTAMP_SERVICE", "evoucher.model.EStampService");
		File_MAPPINGS.put("M_DATABASE_SERVICE",
				"evoucher.model.DataBaseService");
		File_MAPPINGS.put("M_PARSE_PAUSE", "evoucher.model.ParsePause");
		File_MAPPINGS.put("M_CALL_BACK_PARAMETER",
				"evoucher.service.callback.address");
		File_MAPPINGS.put("M_REQUEST_NOTIFY", "evoucher.service.requestData.address"); 
		File_MAPPINGS.put("M_CALL_BACK_THREAD_COUNT", "evoucher.service.callback.thread.count");
		
		File_MAPPINGS.put("S_SIGN_SERVICE", "evoucher.switch.SignService");
		File_MAPPINGS
				.put("S_MESSAGE_SERVICE", "evoucher.switch.MessageService");
		File_MAPPINGS.put("S_ESTAMP_SERVICE", "evoucher.switch.EStampService");
		File_MAPPINGS.put("S_ESTAMP_ALLSIGN", "evoucher.switch.EStampAllSign");
		File_MAPPINGS.put("S_ESTAMP_FUND", "evoucher.switch.EStampFund");
		File_MAPPINGS.put("S_RECEIVE_VIERFY", "evoucher.switch.ReceiveVerfy");
		File_MAPPINGS.put("S_READ_IS_RETURN", "evoucher.switch.IsReturn");
		File_MAPPINGS.put("S_CHECK_IS", "evoucher.switch.VoucherFieldCheck");
		File_MAPPINGS.put("S_CALL_BACK_FUNCTION",
				"evoucher.switch.CallBackFuction");
		File_MAPPINGS.put("S_ERROR_MSG_MODEL_FLAG", "evoucher.switch.ErrMsgModeFlag");
		
		File_MAPPINGS.put("S_RECEIVE_MSG_REQUESTDATA_FLAG", "evoucher.switch.requestData");
		File_MAPPINGS.put("S_RECEIVE_MSG_SENDDATA_FLAG", "evoucher.switch.sendData");
		File_MAPPINGS.put("S_RECEIVE_MSG_SENDDATA_CALLBACK_FLAG", "evoucher.switch.sendData.CallBackFuncton");
	
		/** 凭证库服务版本号 */
		File_MAPPINGS.put("EVOUCHER_SERVICE_VERSION", "evoucher.service.version");
		//原文篡改编码
		File_MAPPINGS.put("M_EVOUCHER_VERFIY_SIGN_CODE", "evoucher.verfiySignStamp.code");
		
	}

	public static String getEVConfValue(String key) {
		if(File_MAPPINGS.containsKey(key))
			key=File_MAPPINGS.get(key);
		return evoucherConfPro.getProperty(key);
	}

	/**
	 * 获取自定义包路径的配置文件
	 * 
	 * @param customPath
	 *            自定义路径

	public static Properties getProByCustomPath(String customPath,
			String fileName) {
		InputStream in = null;
		Properties prop = new Properties();
		try {
			in = PropertiesHander.class.getResourceAsStream(customPath
					+ fileName);
			prop.load(in);
		} catch (Exception e) {
			throw new EVoucherException(ExceptionConstant.EVS601 + "获取文件["

		}
		return prop;
	}

}

第三种情况：对于一些配置文件可以直接放在代码里面，例如：Boolean型的【可以作为开关】，设置其变量状态，然后初始化，在业务逻辑代码中去取【这样就实现了配置的作用】如下：
