Java 实现微信和支付宝支付

一、前期准备
1、申请好微信商户号appid，拿到商户id和商户秘钥，退款的话需要商户证书
2、申请好支付宝商户号appid，商户公钥和秘钥（需要用支付宝工具自己生成），支付宝退款不需要证书

二、数据库表设计
1、微信支付配置表

CREATE TABLE `py_wx_config` (
`wx_config_id` varchar(18) NOT NULL COMMENT ‘微信支付配置ID’,
`appid` varchar(128) DEFAULT NULL COMMENT ‘微信公众号ID’,
`mch_id` varchar(128) DEFAULT NULL COMMENT ‘商户号ID’,
`mch_key_secret` varchar(2200) DEFAULT NULL COMMENT ‘商户安全密钥’,
`crt_path` varchar(200) DEFAULT NULL COMMENT ‘商户证书存放路径’,
`app_secret` varchar(2200) DEFAULT NULL COMMENT ‘公众号安全密钥’,
`create_id` varchar(18) DEFAULT NULL COMMENT ‘创建人’,
`create_time` datetime DEFAULT NULL COMMENT ‘创建时间’,
`upd_id` varchar(18) DEFAULT NULL COMMENT ‘修改人’,
`upd_time` datetime DEFAULT NULL COMMENT ‘修改时间’,
`delete_flag` tinyint(1) NOT NULL DEFAULT ‘0’ COMMENT ‘删除标志’,
`app_code` varchar(18) NOT NULL COMMENT ‘商家编码’,
`bm_code` varchar(20) DEFAULT NULL COMMENT ‘部门编码’,
PRIMARY KEY (`wx_config_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 ROW_FORMAT=COMPACT COMMENT=’微信支付配置’;

 
2、微信小程序支付配置表

CREATE TABLE `py_wx_min_config` (
`wx_min_config_id` varchar(18) NOT NULL COMMENT ‘微信支付配置ID’,
`appid` varchar(128) DEFAULT NULL COMMENT ‘微信公众号ID’,
`mch_id` varchar(128) DEFAULT NULL COMMENT ‘商户号ID’,
`mch_key_secret` varchar(2200) DEFAULT NULL COMMENT ‘商户安全密钥’,
`crt_path` varchar(200) DEFAULT NULL COMMENT ‘商户证书存放路径’,
`app_secret` varchar(2200) DEFAULT NULL COMMENT ‘公众号安全密钥’,
`create_id` varchar(18) DEFAULT NULL COMMENT ‘创建人’,
`create_time` datetime DEFAULT NULL COMMENT ‘创建时间’,
`upd_id` varchar(18) DEFAULT NULL COMMENT ‘修改人’,
`upd_time` datetime DEFAULT NULL COMMENT ‘修改时间’,
`delete_flag` tinyint(1) NOT NULL DEFAULT ‘0’ COMMENT ‘删除标志’,
`app_code` varchar(18) NOT NULL COMMENT ‘商家编码’,
`sys_software_code` varchar(18) DEFAULT NULL COMMENT ‘系统编码’,
PRIMARY KEY (`wx_min_config_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 ROW_FORMAT=COMPACT COMMENT=’微信支付配置’;

 
3、支付宝支付配置表

CREATE TABLE `py_alipay_config` (
`alipay_config_id` varchar(18) NOT NULL COMMENT ‘支付宝支付配置ID’,
`ali_private_key` varchar(2200) DEFAULT NULL COMMENT ‘支付宝密钥’,
`ali_public_key` varchar(2200) DEFAULT NULL COMMENT ‘支付宝公钥’,
`ali_appid` varchar(128) DEFAULT NULL COMMENT ‘支付宝appid’,
`create_id` varchar(18) DEFAULT NULL COMMENT ‘创建人’,
`create_time` datetime DEFAULT NULL COMMENT ‘创建时间’,
`upd_id` varchar(18) DEFAULT NULL COMMENT ‘修改人’,
`upd_time` datetime DEFAULT NULL COMMENT ‘修改时间’,
`delete_flag` tinyint(1) NOT NULL DEFAULT ‘0’ COMMENT ‘删除标志’,
`app_code` varchar(18) NOT NULL COMMENT ‘商家编码’,
PRIMARY KEY (`alipay_config_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 ROW_FORMAT=COMPACT COMMENT=’支付宝支付配置’;

 
4、支付流水记录表

CREATE TABLE `py_pay_log` (
`pay_log_id` varchar(18) NOT NULL COMMENT ‘支付流水ID’,
`pay_no` varchar(20) DEFAULT NULL COMMENT ‘支付订单号’,
`third_id` varchar(64) DEFAULT NULL COMMENT ‘微信支付宝订单ID’,
`money_type` varchar(20) DEFAULT NULL COMMENT ‘支付类型 0-微信 1-支付宝 2-会员卡 3-银联’,
`mq_topic` varchar(100) DEFAULT NULL COMMENT ‘MQ主题’,
`mq_status` tinyint(3) DEFAULT NULL COMMENT ‘MQ发送状态 0-待发送 1-已发送 2-发送失败’,
`mq_remark` varchar(100) DEFAULT NULL COMMENT ‘MQ发送备注’,
`request` text COMMENT ‘发送数据’,
`response` text COMMENT ‘返回数据’,
`fee` decimal(14,2) DEFAULT NULL COMMENT ‘订单金额’,
`create_id` varchar(18) DEFAULT NULL COMMENT ‘创建人’,
`create_time` datetime DEFAULT NULL COMMENT ‘创建时间’,
`upd_id` varchar(18) DEFAULT NULL COMMENT ‘修改人’,
`upd_time` datetime DEFAULT NULL COMMENT ‘修改时间’,
`delete_flag` tinyint(1) NOT NULL DEFAULT ‘0’ COMMENT ‘删除标志’,
`app_code` varchar(18) NOT NULL COMMENT ‘商家编码’,
`pay_config_json_str` longtext COMMENT ‘支付配置’,
PRIMARY KEY (`pay_log_id`) USING BTREE
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 ROW_FORMAT=DYNAMIC COMMENT=’支付流水’;

 
5、支付失败记录表

CREATE TABLE `pay_fail_log` (
`pay_id` varchar(18) NOT NULL,
`json_date` varchar(500) DEFAULT NULL,
`create_id` varchar(18) DEFAULT NULL,
`create_time` datetime DEFAULT NULL,
`update_id` varchar(18) DEFAULT NULL,
`update_time` datetime DEFAULT NULL,
`app_code` varchar(18) NOT NULL,
`delete_flag` tinyint(1) DEFAULT ‘0’ COMMENT ‘是否删除:0-否；1-是’,
PRIMARY KEY (`pay_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 ROW_FORMAT=COMPACT;
