程序中时用第三方接口，我希望将程序结果输出到字符串中，这样可以嵌入到网页中，但是接口的函数中固定输出到终端，试了n种方法，包括jar文件的反编译，修改其中的class文件，在打包，但是这样会出现各种问题，在无奈之余，在网上搜到一篇文章http://zhouzaibao.javaeye.com/blog/338113，重定向printStackTree到字符串，正是我所需要的
- StringWriter sw = new StringWriter();
- PrintWriter pw = new PrintWriter(sw);
- ex.printStackTrace(pw);
- return sw.toString();
