一、前言

作者: 杨不易呀

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

第一章从零玩转系列之微信支付开篇
第二章从零玩转系列之微信支付安全
第三章从零玩转系列之微信支付实战基础框架搭建
第四章从零玩转系列之微信支付实战PC端支付下单接口搭建

3.创建yml配置

server:
  port: 9080
spring:
  application:
    name: wx-play-demo-blog
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: com.p6spy.engine.spy.P6SpyDriver
    url: jdbc:p6spy:mysql://127.0.0.1:3306/payment_demo?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&rewriteBatchedStatements=true
    username: xxxxxxxxxxxxx
    password: xxxxxxxxx
  servlet:
    multipart:
      max-file-size: 200MB  #设置单个文件的大小  因为springboot内置tomact的的文件传输默认为10MB
      max-request-size: 500MB   #设置单次请求的文件总大小
      enabled: true    #千万注意要设置该参数，否则不生效
  mvc:
    format:
      date-time: yyyy-MM-dd HH:mm:ss
  #jackson配置
  jackson:
    # 日期格式化
    date-format: yyyy-MM-dd HH:mm:ss
    serialization:
      # 格式化输出
      INDENT_OUTPUT: false
      # 忽略无法转换的对象
      fail_on_empty_beans: false
    deserialization:
      # 允许对象忽略json中不存在的属性
      fail_on_unknown_properties: false
mybatis-plus:
  configuration:
    map-underscore-to-camel-case: true
    auto-mapping-behavior: full
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
  mapper-locations: classpath*:mapper/*.xml
logging:
  level:
    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;
import java.util.Date;
/**
 * 自动填充
 * @author Yang Shuai
 **/
@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;
import com.baomidou.mybatisplus.core.incrementer.DefaultIdentifierGenerator;
import com.baomidou.mybatisplus.core.incrementer.IdentifierGenerator;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.BlockAttackInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Configuration
@MapperScan("com.yby6.mapper")
@EnableTransactionManagement(proxyTargetClass = true)
public class MyBatisPlusConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        // 分页插件
        interceptor.addInnerInterceptor(paginationInnerInterceptor());
        // 乐观锁插件
        interceptor.addInnerInterceptor(optimisticLockerInnerInterceptor());
        // 针对 update 和 delete 语句 作用: 阻止恶意的全表更新删除
        interceptor.addInnerInterceptor(new BlockAttackInnerInterceptor());
        return interceptor;
    }
    /**
     * 分页插件，自动识别数据库类型
     */
    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 com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.AutoConfiguration;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
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;
import java.io.IOException;
/**
 * 超出 JS 最大最小值 处理
 *
 * @author Yang Shuai
 */
@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;
    /**
     * 提供实例
     */
    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;
import java.io.Serial;
import java.io.Serializable;
/**
 * 响应信息主体
 *
 * @author Yang Shuai
 */
public class R<T> implements Serializable {
    /**
     * 成功
     */
    public static final int SUCCESS = 200;
    /**
     * 失败
     */
    public static final int FAIL = 500;
    @Serial
    private static final long serialVersionUID = 1L;
    /**
     * 消息状态码
     */
    private int code;
    /**
     * 消息内容
     */
    private String msg;
    /**
     * 数据对象
     */
    private T data;
    public static <T> R<T> ok() {
        return restResult(null, SUCCESS, "操作成功");
    }
    public static <T> R<T> ok(T data) {
        return restResult(data, SUCCESS, "操作成功");
    }
    public static <T> R<T> ok(String msg) {
        return restResult(null, SUCCESS, msg);
    }
    public static <T> R<T> ok(String msg, T data) {
        return restResult(data, SUCCESS, msg);
    }
    public static <T> R<T> fail() {
        return restResult(null, FAIL, "操作失败");
    }
    public static <T> R<T> fail(String msg) {
        return restResult(null, FAIL, msg);
    }
    public static <T> R<T> fail(T data) {
        return restResult(data, FAIL, "操作失败");
    }
    public static <T> R<T> fail(String msg, T data) {
        return restResult(data, FAIL, msg);
    }
    public static <T> R<T> fail(int code, String msg) {
        return restResult(null, code, msg);
    }
    public static <T> R<T> check(int row) {
        return row > 0 ? ok() : fail();
    }
    public static <T> R<T> check(boolean isTure) {
        return isTure ? ok() : fail();
    }
    /**
     * 返回警告消息
     *
     * @param msg 返回内容
     * @return 警告消息
     */
    public static <T> R<T> warn(String msg) {
        return restResult(null, 601, msg);
    }
    /**
     * 返回警告消息
     *
     * @param msg  返回内容
     * @param data 数据对象
     * @return 警告消息
     */
    public static <T> R<T> warn(String msg, T data) {
        return restResult(data, 601, msg);
    }
    private static <T> R<T> restResult(T data, int code, String msg) {
        R<T> r = new R<>();
        r.setCode(code);
        r.setData(data);

        return r;
    }
    public static <T> Boolean isError(R<T> ret) {
        return !isSuccess(ret);
    }
    public static <T> Boolean isSuccess(R<T> ret) {
        return R.SUCCESS == ret.getCode();
    }
    public int getCode() {

    public T getData() {
        return data;
    }
    public void setData(T data) {
