public static Writer out = null;

try{

    //后边的都没走

        e.printStackTrace();
       
        throw new RuntimeException(e);
    }finally {
        //如果out不是null，才需要close()
        if (out != null){
            try {
                
                out.flush();
                out.close();
                out = null;
                
            } catch (IOException e) {
                
                e.printStackTrace();
            }
        }
    }

放啦，在try里的 ，还有finally，可是没有抛出异常，连finally都没走，就是走到这个语句之后服务就直接断了，后边的都没走。
