unterminated string literal

采用

ServletActionContext.getResponse().getWriter()

向前台写信息的时候，经常会出现unterminated string literal错误：未结束的字符串常量，很可能是由于字符串中存在换行符导致的。是存在\r\n

解决办法:

在将result写到前台之前，将字符串中的换行的特殊符号转义掉，

PrintWriter pw = ServletActionContext.getResponse().getWriter();
result = result.replace("\n\r", "<br>&nbsp;&nbsp;");
result = result.replace("\r\n", "<br>&nbsp;&nbsp;");
result = result.replace("\t", "&nbsp;&nbsp;&nbsp;&nbsp;");
result = result.replace(" ", "&nbsp;");

result = result.replace("\"", "\\" + "\"");
pw.print(result);
