1.获取src/config目录下的配置文件
InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("config/sms.properties");
Properties p = new Properties();
// 把配置文件载入Properties类
p.load(inputStream);
String serviceUrl = p.getProperty("serviceUrl");
//System.out.println(p.getProperty("serviceUrl"));
2.获取指定WebRoot/classes目录下的配置文件
Properties p = new Properties();
try {
String path = this.getClass().getResource("/").getPath();//得到工程名WEB-INF/classes/路径
path = path.substring(1, path.indexOf("classes"));//从路径字符串中取出工程路径
p.load(new FileInputStream(path + "/config/sms.properties"));
String lzfx_url = p.getProperty("LZFX_URL");
} catch (Exception e) {
e.printStackTrace();
}
