java接口入参模板化，适用于企业化服务远程调度模板化的场景，接口入参实现高度可配置化

需求：远程服务接口模板化配置提供接入服务

模板接口分为三个模块：功能路由、参数校验、模板入库

路由：这里的实现方式很简单，就是根据业务标识找到对应的处理方法

参数校验：

　　　　参数校验这步涉及模板和校验类两个核心模块

　　　　提供一个表设计：

CREATE TABLE `account_template_validation` (
`id` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
`city_no` VARCHAR(50) NOT NULL COMMENT '城市编码',
`template_id` VARCHAR(64) NOT NULL COMMENT '模板id',
`properties` VARCHAR(4000) NOT NULL COMMENT '模板',
`isReturn` VARCHAR(10) NOT NULL COMMENT '是否要跳转',
`create_time` DATETIME DEFAULT NULL COMMENT '创建时间',
`update_time` DATETIME DEFAULT NULL COMMENT '更新时间',
PRIMARY KEY (`id`),
INDEX `cityNo` (`city_no`),
INDEX `templateId` (`template_id`)
) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8

模板表模板的值需要用到json格式的报文：

{
"A": {
"notNull": "false",
"length": "15",
"toFiled": "B"
},
"A": {
"notNull": "false",
"length": "15",
"toFiled": "C"
},
"gmt_time": {
"notNull": "false",
"length": "15",
"toFiled": "gmtTime",
"formate": "((([0-9]{3}[1-9]|[0-9]{2}[1-9][0-9]{1}|[0-9]{1}[1-9][0-9]{2}|[1-9][0-9]{3})(((0[13578]|1[02])(0[1-9]|[12][0-9]|3[01]))|((0[469]|11)(0[1-9]|[12][0-9]|30))|(02(0[1-9]|[1][0-9]|2[0-8]))))|((([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00))0229))([0-1][0-9]|2[0-3])([0-5][0-9])([0-5][0-9])$"
}
}

模板的报文是包含入参字段配置的属性

核心校验类：

public static void main(String[] args) {
        JSONObject template = JSON.parseObject("{"si_type":{"notNull":"true","length":"32","toFiled":"siType"},"account_balance":{"notNull":"false","length":"15","toFiled":"accountBalance"},"pay_cost_base":{"notNull":"false","length":"15","toFiled":"payCostBase"},"pay_cost_month":{"notNull":"true","length":"6","toFiled":"payCostMonth"},"pay_cost_total":{"notNull":"false","length":"15","toFiled":"payCostTotal"},"pay_cost_person":{"notNull":"false","length":"15","toFiled":"payCostPerson"},"pay_cost_unit":{"notNull":"false","length":"15","toFiled":"payCostUnit"},"account_person":{"notNull":"false","length":"15","toFiled":"accountPerson"},"extend_params_test1":{"notNull":"false","length":"15","toFiled":"extend_params"},"extend_params_test2":{"notNull":"false","length":"15","toFiled":"extend_params"}}");
