1.转换字段名为get/set方法名

/**     * 给Object对象设置某属性值     * @param obj Object     * @param columnName String     * @param value Object     * @return     */    public Boolean setPropertyByColumn(Object obj,String columnName,Object value) {        try {            if (obj!=null && columnName!=null) {                java.lang.reflect.Method set = obj.getClass().getDeclaredMethod(                        transColumn2GetOrSetMethodName(columnName,"set"), value.getClass());                set.invoke(obj, value);                return true;            } else {                return false;            }        } catch (Exception e) {            return false;        }    }        /**     * 根据列名获取对应的get或set方法名     * @param column String     * @param setOrget String     * @return     */    public String transColumn2GetOrSetMethodName(String column,String setOrget){        if (column==null || setOrget==null) {            return null;        }        if (setOrget.matches("set|get")) {            String[] colps = column.toLowerCase().split("_");            String methodName = "set";            for (int i = 0; i < colps.length; i++) {                if (colps[i].length() > 1) {                    methodName += new String(colps[i].substring(0, 1).toUpperCase());                    methodName += new String(colps[i].substring(1));                } else {                    methodName += new String(colps[i].toUpperCase());                }            }            return methodName;        } else {            System.out.println("param setOrget must be set or get.");             return null;        }    }        /**     * 获取Object某属性值     * @param obj Object     * @param columnName String     * @return     */    public Object getPropertyByColumn(Object obj,String columnName) {        try {            if (obj!=null && columnName!=null) {                java.lang.reflect.Method get = obj.getClass().getDeclaredMethod(                        transColumn2GetOrSetMethodName(columnName,"get"));                return get.invoke(obj);            } else {                return null;            }        } catch (Exception e) {                    return null;        }    }

 

2.ServletInputStream数据流接收并存入byte数组中进行缓存

1             ServletInputStream sis = this.getRequest().getInputStream();2             int readCount = 0; //已读取字节数3             int count = getRequest().getContentLength() ; //当前可读取字节数4             byte[] buffer = new byte[count];5             while (readCount < count) {6                 readCount += sis.read(buffer, readCount, count-readCount);7             }
