java获得request所有参数

                        // URL参数传递
Map<String, String> reqMap = new HashMap<String, String>();
Enumeration enum_term = request.getParameterNames();
while (enum_term.hasMoreElements()) {
String paramName = (String) enum_term.nextElement();
String paramValue = request.getParameter(paramName);
reqMap.put(paramName, paramValue);

}

                // 根据url参数替换语句参数
Set<String> key = reqMap.keySet();
for (Iterator<String> it = key.iterator(); it.hasNext();) {
String params = it.next();
sqlTextString = sqlTextString.replace(":" + params, reqMap
.get(params));
}
