java中读取配置文件方法二

在项目启动时加载

package com.founder.ids.listener;

import java.io.IOException;
import java.util.List;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.springframework.core.io.ClassPathResource;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.founder.ids.cache.CacheManager;
import com.founder.ids.common.WebProperties;
import com.founder.ids.entity.Organization;
import com.founder.ids.service.IHealthOfficerService;
import com.founder.ids.service.IOrganizationService;

public class PropertiesInitListener implements ServletContextListener {

	private static final String WEBSERVICE_CONFIG_FILE = "config/common-web.properties";

	//@Resource(name = "organizationService")
	IOrganizationService organizationService;
	IHealthOfficerService doctorService;
	
	@Override
	public void contextDestroyed(ServletContextEvent event) {
	//	System.out.println("===hah2====");
	}

	@Override
	public void contextInitialized(ServletContextEvent event) {
		organizationService = this.getOrganizationService(event.getServletContext());
		List<Organization> list = organizationService.getOrganizations();
		for(Organization org:list){
			CacheManager.orgWebServiceUrlMap.put(org.getId().toString(), org.getWebserviceUrl());
		}
		ClassPathResource cr = new ClassPathResource(WEBSERVICE_CONFIG_FILE);
		try {
			WebProperties.getInstance();
			WebProperties.getProperties().load(cr.getInputStream());
		} catch (IOException ex) {
			throw new RuntimeException("Cannot find Configuration " + PropertiesInitListener.WEBSERVICE_CONFIG_FILE);
		}
	}
	
	protected IOrganizationService getOrganizationService(ServletContext servletContext) {
	       return (IOrganizationService) WebApplicationContextUtils.getWebApplicationContext(servletContext).getBean("organizationService"); 
	    }
}

代码实现

package com.founder.ids.common;

import java.util.Properties;

import com.founder.fasf.util.ObjectUtil;

public class WebProperties {
	private static final WebProperties instance = new WebProperties();
	
	private static Properties properties;
	
	public static Properties getProperties() {
		return properties;
	}

	public static void setProperties(Properties properties) {
		WebProperties.properties = properties;
	}

	private WebProperties(){
		
	}
	
	public static WebProperties getInstance(){
		if(properties == null){
			properties = new Properties();
		}
		return instance;
	}
	
	/**
	 * 根据Key获取msg
	 * @param msgKey
	 * @param ...args
	 * 
	 * */
	public static String getMsg(String msgKey,String ...args){
		String msg = properties.getProperty(msgKey);
		
		if(msg == null){
			return "";
		}
		
		if(args == null || args.length == 0){
			return msg;
		}
		for(int i = 0; i < args.length; i++){
			String reg = "{" + i + "}";
			String rep = args[i];
			if(ObjectUtil.isNotEmpty(rep)) {
				msg = msg.replace(reg, rep);
			}
		}
		return msg;
	}
}

如何调用

package com.founder.ids.common;

import com.founder.fasf.util.ObjectUtil;


public class SiteNoticeUtil {
	/**
	 * 根据Key获取msg
	 * @param msgKey
	 * @param ...args
	 * 
	 * */
	public static String getMsg(String msgKey,String ...args){
		String msg = WebProperties.getMsg(msgKey);
		
		if(msg == null){
			return "";
		}
		
		if(args == null || args.length == 0){
			return msg;
		}
		for(int i = 0; i < args.length; i++){
			String reg = "{" + i + "}";
			String rep = args[i];
			if(ObjectUtil.isNotEmpty(rep)) {
				msg = msg.replace(reg, rep);
			}
		}
		return msg;
	}
}
SiteNoticeUtil.getMsg(
					"sms.reserve.reg.cancel",
					DateUtil.getDateTime("yyyy/MM/dd", reserveRegister.getReserveDate()) + " "
							+ cv.getName(), organizationDao.get(reserveRegister.getHospitalId())
							.getName(), reserveRegister.getDoctor().getName())
