一直用一个方法安然无恙，今天在新项目中突然乱码了，原代码：
ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream is = null; is = classLoader.getResourceAsStream("config/constant.properties"); if (is != null) { try { props.load(is); }
优化后：
static { ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream is = null; is = classLoader.getResourceAsStream("config/constant.properties"); if (is != null) { try { props.load(new InputStreamReader(is,"UTF-8")); } ……
classLoader.getResourceAsStream中文乱码
