### 1. Object转BigDecimal类型 ###

--------------------

**Object类型转化成BigDecimal:**

/**
         * Object转BigDecimal类型
         *
         * @param value 要转的object类型
         * @return 转成的BigDecimal类型数据
         */
        public static BigDecimal getBigDecimal(Object value) {
        
            BigDecimal ret = null;
            if (value != null) {
        
                if (value instanceof BigDecimal) {
        
                    ret = (BigDecimal) value;
                } else if (value instanceof String) {
        
                    ret = new BigDecimal((String) value);
                } else if (value instanceof BigInteger) {
        
                    ret = new BigDecimal((BigInteger) value);
                } else if (value instanceof Number) {
        
                    ret = new BigDecimal(((Number) value).doubleValue());
                } else {
        
                    throw new ClassCastException("Not possible to coerce [" + value + "] from class " + value.getClass() + " into a BigDecimal.");
                }
            }
            return ret;
        }
