web应用文本输入框内容存储的特殊字符转换
文本框输入内容存储，需要转换特殊字符
1、保存到数据库之前

char[]input=text.toCharArray();StringBuffer out = new StringBuffer();int len = input.length;char c;int i=0;while(i<len){        c=input[i];if(c=='<')  out.append("<");        else if(c=='>')          out.append(">");        else if(c=='\r'){          char h=input[i+1]          if(h=='\n'){             out.append("<BR>");          }        }else if(c=='\n'){  out.append('<BR>');}else if(c==' '){          out.append(" ");        }else if(c=='"'){          out.append(""");         }else          out.append(c);       i++;}text=out.toString();text=text.replace("\\","\\\\");转换 \text=text.replace("'","\\'");转换 'text=text.replace("\"","\\\"")转换 "

2、从数据库取出，显示到页面之前

memo = memo.replace("\\\\","\\");
memo = memo.replace("\\'","'");
memo = memo.replace("\\\"","\"");
