Answer 3

//禁用HTML代码编码
public String html(String s){
String re;
re=replace(s,"<","&lt;");
    re=replace(re,">","&gt;");
    re=replace(re,"\n","<br>");
    re=replace(re," ","&nbsp;");
    re=replace(re,"'","&#39");
    return re;
}把用户提交的东西，写数据库的时候先禁用html

Answer 4

//用指定的字符替换字符串中某个字符
public String replace(String con,String tag,String rep){
int j=0;
int i=0;
int k=0;
String RETU="";
String temp=con;
int tagc=tag.length();
while(i<con.length()){
if(con.substring(i).startsWith(tag)){
temp=con.substring(j,i)+rep;
RETU+=temp;
i+=tagc;
j=i;
}
else{i+=1;
}
}
RETU+=con.substring(j);
return RETU;
}//禁用HTML代码编码
public String html(String s){
String re;
re=replace(s,"<","&lt;");
    re=replace(re,">","&gt;");
    re=replace(re,"\n","<br>");
    re=replace(re," ","&nbsp;");
    re=replace(re,"'","&#39");
    return re;
}刚才少给了你一个函数

用这个试试
public static String returnToBr(String sStr)
 { 
if (sStr == null || sStr.equals(""))
 { 
return sStr; 
}  StringBuffer sTmp = new StringBuffer(); 
int i = 0; 
while (i <= sStr.length()-1)
 { 
if (sStr.charAt(i) == '\n'||sStr.charAt(i)=='\r') 
{ 
sTmp = sTmp.append("<br>"); 
} else if (sStr.charAt(i)==' ')
 { 
sTmp = sTmp.append("&nbsp;"); 
}else
 { 
sTmp = sTmp.append(sStr.substring(i,i+1)); 
 } 
i++; 
} 
String S1;
S1=sTmp.toString();
return S1; 
}
