获取request里面所有的Parameter所有的请求参数

public static Map<String,Object> showParams(HttpServletRequest request) {
Map<String,Object> map = new HashMap<String,Object>();
Enumeration paramNames = request.getParameterNames();
while (paramNames.hasMoreElements()) {
String paramName = (String) paramNames.nextElement();

            String[] paramValues = request.getParameterValues(paramName);  
            if (paramValues.length >0) {  
                String paramValue = paramValues[0];  
                if (paramValue.length() != 0) {  
                    map.put(paramName, paramValue);  
                }  
            }  
        }  

        Set<Map.Entry<String, Object>> set = map.entrySet();  
        logger.debug("==============================================================");  
        for (Map.Entry entry : set) {  
            logger.debug(entry.getKey() + ":" + entry.getValue());  
        }  
        logger.debug("=============================================================");  
        return map;
    }
