    1.编写验证字符串的代码:

    public static boolean isIllegal(String str){ if(str == null){ str = ""; } if(str.indexOf(">") != -1 || str.indexOf("<") != -1 || str.indexOf("and") != -1 || str.indexOf("or") != -1 || str.indexOf("OR") != -1 || str.indexOf("exec") != -1 || str.indexOf("EXEC") != -1 || str.indexOf("insert") != -1 || str.indexOf("INSERT") != -1 || str.indexOf("select") != -1 || str.indexOf("SELECT") != -1 || str.indexOf("union") != -1 || str.indexOf("UNION") != -1 || str.indexOf("update") != -1 || str.indexOf("UPDATE") != -1 || str.indexOf("count") != -1 || str.indexOf("count") != -1 ){ return true; } return false; }
