                                Object... values)

表达式过滤

参数:

expression - 表达式，其中#{}和${}中间可以使用占位字段，解析时#{}会默认替换成values对应的值，${}替换成字段对应表中的列名

示例一：NOW()
示例二：DATE_FORMAT(#{value1},'%Y-%m-%d')
示例二：${age} + #{value1} + #{age}

values - 占位值，对应 #{value1}, #{value2}, #{value3}, #{value...}，通过占位符拼接参数防SQL注入

expression

                                Operator operator,
                                Expression expression)
