一、前言
halo各位大佬很久没更新了最近在搞微信支付,因商户号审核了我半个月和小程序认证也找了资料并且将商户号和小程序进行关联,至此微信支付Native支付完成.此篇文章过长我将分几个阶段的文章发布(项目源码都有,小程序和PC端)
在此之前已经更新了微信支付开篇、微信支付安全、本次更新为项目实战篇,实战篇分为几个章节因为代码量确实有点多哈.
本次项目使用技术栈
后端: SpringBoot3.1.x、Mysql8.0、MybatisPlus
前端: Vue3、Vite、ElementPlus
小程序: Uniapp、Uview
二、项目创建
1. 创建SpringBoot项目(wx-play-demo) 3.x (这是我的版本) 使用JDK 17 该博文案例已上传到 gitee 仓库

3.创建yml配置
server:

auto-mapping-behavior: full
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
mapper-locations: classpath*:mapper/*.xml
logging:

root: info三、创建配置文件
1.项目当中创建config目录存放配置文件
创建数据填充配置
package com.yby6.config;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;

/**

@Slf4j
public class MyMetaObjectHandler implements MetaObjectHandler {
@Override
public void insertFill(MetaObject metaObject) {
log.info("start insert fill ....");
this.strictInsertFill(metaObject, "createTime", Date::new, Date.class); // 起始版本 3.3.3(推荐)
this.strictUpdateFill(metaObject, "updateTime", Date::new, Date.class); // 起始版本 3.3.3(推荐)
}
@Override
public void updateFill(MetaObject metaObject) {
log.info("start update fill ....");
this.strictUpdateFill(metaObject, "updateTime", Date::new, Date.class); // 起始版本 3.3.3(推荐)
}
}创建MyBatisPlusConfig配置
package com.yby6.config;
import cn.hutool.core.net.NetUtil;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;

// 针对 update 和 delete 语句 作用: 阻止恶意的全表更新删除

return interceptor;
}
/**

*/
public PaginationInnerInterceptor paginationInnerInterceptor() {
PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();
// 设置最大单页限制数量，默认 500 条，-1 不受限制
paginationInnerInterceptor.setMaxLimit(-1L);
// 分页合理化
paginationInnerInterceptor.setOverflow(true);
return paginationInnerInterceptor;
}
/**
* 乐观锁插件
*/
public OptimisticLockerInnerInterceptor optimisticLockerInnerInterceptor() {
return new OptimisticLockerInnerInterceptor();
}
/**
* 元对象字段填充控制器
*/
@Bean
public MetaObjectHandler metaObjectHandler() {
return new MyMetaObjectHandler();
}
/**
* 使用网卡信息绑定雪花生成器
* 防止集群雪花ID重复
*/
@Primary
@Bean
public IdentifierGenerator idGenerator() {
return new DefaultIdentifierGenerator(NetUtil.getLocalhost());
}
}创建 jackson配置序列化时间
package com.yby6.config;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;

import org.springframework.boot.autoconfigure.jackson.JacksonAutoConfiguration;
import org.springframework.context.annotation.Bean;
import java.math.BigDecimal;
import java.math.BigInteger;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.TimeZone;
/**
* jackson 配置
*
* @author Yang Shuai
*/
@Slf4j
@AutoConfiguration(before = JacksonAutoConfiguration.class)
public class JacksonConfig {
@Bean
public Jackson2ObjectMapperBuilderCustomizer customizer() {
return builder -> {
// 全局配置序列化返回 JSON 处理
JavaTimeModule javaTimeModule = new JavaTimeModule();
javaTimeModule.addSerializer(Long.class, BigNumberSerializer.INSTANCE);
javaTimeModule.addSerializer(Long.TYPE, BigNumberSerializer.INSTANCE);
javaTimeModule.addSerializer(BigInteger.class, BigNumberSerializer.INSTANCE);
javaTimeModule.addSerializer(BigDecimal.class, ToStringSerializer.instance);
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(formatter));
javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(formatter));
builder.modules(javaTimeModule);
builder.timeZone(TimeZone.getDefault());
log.info("初始化 jackson 配置");
};
}
}创建 JS精度配置
package com.yby6.config;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.fasterxml.jackson.databind.annotation.JacksonStdImpl;
import com.fasterxml.jackson.databind.ser.std.NumberSerializer;

/**

*/
@JacksonStdImpl
public class BigNumberSerializer extends NumberSerializer {
/**
* 根据 JS Number.MAX_SAFE_INTEGER 与 Number.MIN_SAFE_INTEGER 得来
*/
private static final long MAX_SAFE_INTEGER = 9007199254740991L;
private static final long MIN_SAFE_INTEGER = -9007199254740991L;
/**

*/
public static final BigNumberSerializer INSTANCE = new BigNumberSerializer(Number.class);
public BigNumberSerializer(Class<? extends Number> rawType) {
super(rawType);
}
@Override
public void serialize(Number value, JsonGenerator gen, SerializerProvider provider) throws IOException {
// 超出范围 序列化位字符串
if (value.longValue() > MIN_SAFE_INTEGER && value.longValue() < MAX_SAFE_INTEGER) {
super.serialize(value, gen, provider);
} else {
gen.writeString(value.toString());
}
}
}创建枚举参数前往仓库下载吧我不想贴了累了兄弟们
https://gitee.com/yangbuyi/wxDemo/tree/master/src/main/java/com/yby6/enums
创建返回对象
package com.yby6.reponse;

}创建MybatisExceptionHandler

4.idea链接mysql
⚠️ 推荐一个插件一键生成CRUD
💰 MyBatisCodeHelperPro (Marketplace Edition)
🔗 打开链接好的数据库管理选择到对应的表右击
🦐 下面的选项卡里面的配置
- lombok 勾选 @Data
- 定制默认方法可以全部去掉
- mybatisPlus配置勾选 mybatisPlus3 和 idType选择为 ASSIGN_ID
- 其他的你看着来吧....
✅ 直接确定生成了一个CRUD 接下来将后面的三个表也一样的操作吧
👌 最终如此
5. 微信配置-基础支付API V3
1.引入支付参数配置
- 在resources当中创建wechat文件夹
- 创建
wxpay.properties复制到wechat当中
# 商户ID
wxpay.mch-id=xxxxx
# 商户平台号
wxpay.mch-serial-no=xxxxx
# 商户证书
wxpay.private-key-path=wechat/apiclient_key.pem
# 微信平台证书
wxpay.platformCertPath=wechat/wechatpay_2694B2E0B2719A25EE1063EE02CFC78EE035E8CF.pem
# 下载地址参考: https://github.com/wechatpay-apiv3/CertificateDownloader
# 商户api v3
wxpay.api-v3-key=xxxxx
# 小程序appid
wxpay.appid=xxxxx
# 小程序密钥
wxpay.secret=xxxxx
wxpay.domain=https://api.mch.weixin.qq.com
# 本地使用内网穿透代理回调
wxpay.notify-domain=https://x x x x x x x x x x x x/wx-api
# 商户apiv2
wxpay.partner-key=xxxxxxxxxxxxx下载微信平台证书
java -jar CertificateDownloader.jar -k ${apiV3key} -m ${mchId} -f ${mchPrivateKeyFilePath} -s ${mchSerialNo} -o ${outputFilePath}
示例：
java -jar CertificateDownloader-1.2.0-jar-with-dependencies.jar
-k=商户v3key
-m=商户ID
-f=/Users/yangbuyi/Documents/workPath/workPath/wx-play-demo/src/main/resources/apiclient_key.pem
-s=商户证书序列号
-o=/Users/yangbuyi/Documents/workPath/workPath/wx-play-demo/src/main/resources
解释：
java -jar CertificateDownloader-1.2.0-jar-with-dependencies.jar
-k=这是对应配置文件当中的 APIV3Key(wxpay.api-v3-key)商户APIV3Key
-m=这是对应配置文件当中的 mchID (wxpay.mch-id) 商户ID
-f=这是对应配置文件当中到 商户证书 apiclient_key.pem (绝对路径地址)
-s=这是对应配置文件当中的 mchSerialNo(wxpay.mch-serial-no)商户平台证书序列号
-o=这是将生成的文件输出到哪个目录下面 (绝对路径地址)这个文件定义了之前我们准备的微信支付相关的参数，例如商户号、APPID、API秘钥等等
