<think>我们这里主要完成后台管理系统的后端部分(SpringBoot)和前端部分(Vue3)的代码。由于微信支付需要商户号等敏感信息,这里我们假设使用微信支付的SDK,并预留配置接口。项目结构:backend/#SpringBoot后端src/main/java/com/example/demo/controller/#控制器service/#服务层repository/#数据访问层entity/#实体类config/#配置类dto/#数据传输对象exception/#异常处理resources/application.propertiesfrontend/#Vue3前端(使用HBuilderX开发,可转为小程序)src/components/#组件pages/#页面store/#Vuex状态管理router/#路由(小程序不需要,但H5需要)App.vuemain.js由于篇幅限制,这里只给出关键代码。后端部分:1.实体类(Entity)扩展:增加会员和支付相关字段2.支付接口对接微信支付(使用官方SDK)3.后台管理接口:用户管理、解析记录管理、会员管理、轮播图管理前端部分:1.首页:解析输入框和轮播图2.我的页面:用户信息展示、解析记录、开通会员(跳转支付)开始编写代码:后端代码:1.实体类扩展```java//User.java增加会员相关字段@Entity@Table(name="users")publicclassUser{//...已有字段(id,username,password,registerTime,parseRecords)@Column(name="avatar_url")privateStringavatarUrl;//用户头像URL@Column(name="is_vip")privateBooleanisVip=false;//是否会员@Column(name="vip_expire_time")privateLocalDateTimevipExpireTime;//会员过期时间//省略getter/setter}//轮播图实体@Entity@Table(name="banners")publicclassBanner{@Id@GeneratedValue(strategy=GenerationType.IDENTITY)privateLongid;@Column(nullable=false)privateStringimageUrl;//图片地址@Column(nullable=false)privateStringlinkUrl;//点击跳转链接(可选)@Column(nullable=false)privateIntegersortOrder=0;//排序@Column(nullable=false)privateBooleanactive=true;//是否激活//gettersandsetters}```2.微信支付服务```java//WxPayService.java@ServicepublicclassWxPayService{//微信支付配置(从配置文件中读取)@Value("${wxpay.appId}")privateStringappId;@Value("${wxpay.mchId}")privateStringmchId;@Value("${wxpay.mchKey}")privateStringmchKey;@Value("${wxpay.notifyUrl}")privateStringnotifyUrl;//创建支付订单(统一下单)publicMap<String,String>createOrder(StringorderId,inttotalFee,Stringbody,Stringopenid)throwsException{WXPaywxpay=newWXPay(newWXPayConfig(){@OverridepublicStringgetAppID(){returnappId;}@OverridepublicStringgetMchID(){returnmchId;}@OverridepublicStringgetKey(){returnmchKey;}//其他配置方法(证书等)根据实际情况实现});Map<String,String>data=newHashMap<>();data.put("body",body);data.put("out_trade_no",orderId);data.put("device_info","WEB");data.put("fee_type","CNY");data.put("total_fee",String.valueOf(totalFee));data.put("spbill_create_ip","123.12.12.123");//实际应获取客户端IPdata.put("notify_url",notifyUrl);data.put("trade_type","JSAPI");//小程序支付data.put("openid",openid);Map<String,String>resp=wxpay.unifiedOrder(data);if("SUCCESS".equals(resp.get("return_code"))&&"SUCCESS".equals(resp.get("result_code"))){//生成小程序端需要的支付参数Map<String,String>result=newHashMap<>();result.put("appId",appId);result.put("timeStamp",String.valueOf(System.currentTimeMillis()/1000));result.put("nonceStr",resp.get("nonce_str"));result.put("package","prepay_id="+resp.get("prepay_id"));result.put("signType","MD5");//生成签名Stringsign=WXPayUtil.generateSignature(result,mchKey,SignType.MD5);result.put("paySign",sign);returnresult;}else{thrownewRuntimeException("微信支付下单失败:"+resp.get("return_msg"));}}//支付回调处理publicvoidprocessNotify(HttpServletRequestrequest,HttpServletResponseresponse)throwsException{//验证签名,处理订单//更新会员状态}}```3.控制器```java//PaymentController.java@RestController@RequestMapping("/api/payment")publicclassPaymentController{privatefinalWxPayServicewxPayService;privatefinalUserServiceuserService;publicPaymentController(WxPayServicewxPayService,UserServiceuserService){this.wxPayService=wxPayService;this.userService=userService;}@PostMapping("/create")publicResponseEntity<?>createPayment(@RequestBodyPaymentRequestrequest,@AuthenticationPrincipalUserDetailsuserDetails){//根据userDetails获取用户信息Useruser=userService.findByUsername(userDetails.getUsername());//生成订单号(示例)StringorderId="ORDER_"+System.currentTimeMillis();try{Map<String,String>payParams=wxPayService.createOrder(orderId,request.getAmount(),"会员开通",user.getWxOpenid()//实际开发中需要存储用户的openid);returnResponseEntity.ok(payParams);}catch(Exceptione){returnResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());}}//支付回调通知接口@PostMapping("/notify")publicvoidnotify(HttpServletRequestrequest,HttpServletResponseresponse){wxPayService.processNotify(request,response);}}//BannerController.java@RestController@RequestMapping("/api/banner")publicclassBannerController{privatefinalBannerRepositorybannerRepository;publicBannerController(BannerRepositorybannerRepository){this.bannerRepository=bannerRepository;}@GetMapping("/active")publicList<Banner>getActiveBanners(){returnbannerRepository.findByActiveTrueOrderBySortOrderAsc();}//后台管理接口(需要管理员权限)@PostMapping@PreAuthorize("hasRole('ADMIN')")publicBannercreateBanner(@RequestBodyBannerbanner){returnbannerRepository.save(banner);}}```4.前端页面(Vue3)示例首页:index.vue```vue<template><div><!--轮播图--><swiper:indicator-dots="true":autoplay="true":interval="3000":duration="1000"><swiper-itemv-for="(item,index)inbanners":key="index"><image:src="item.imageUrl"mode="aspectFill"style="width:100%;height:300rpx;"/></swiper-item></swiper><!--解析输入框--><divclass="input-area"><inputv-model="url"placeholder="请输入视频链接"/><button@click="parse">解析</button></div></div></template><script>import{ref,onMounted}from'vue';import{getBanners}from'@/api/banner';exportdefault{setup(){constbanners=ref([]);consturl=ref

Boot后端和Vue3前端(HBuilderX可转换小程序版本):

```java
// User.java
@Entity
@Table(name = "users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(unique = true, nullable = false)

@Column(name = "create_time", nullable = false)
private LocalDateTime createTime;
@Column(name = "pay_time")
private LocalDateTime payTime;
// Getters & Setters
}
```
2. **微信支付服务**
```java
// WxPayService.java
@Service
public class WxPayService {
@Value("${wxpay.appId}")
private String appId;
@Value("${wxpay.mchId}")
private String mchId;
@Value("${wxpay.mchKey}")
private String mchKey;
@Value("${wxpay.notifyUrl}")
private String notifyUrl;
public Map<String, String> createOrder(User user, String productName, int amount) {
String orderId = "ORDER" + System.currentTimeMillis() + new Random().nextInt(1000);
Map<String, String> data = new HashMap<>();
data.put("appid", appId);
data.put("mch_id", mchId);
data.put("nonce_str", WxPayUtil.generateNonceStr());
data.put("body", productName);
data.put("out_trade_no", orderId);
data.put("total_fee", String.valueOf(amount));
data.put("spbill_create_ip", "用户IP");
data.put("notify_url", notifyUrl);
data.put("trade_type", "JSAPI");
data.put("openid", user.getOpenid());
try {
// 生成签名
String sign = WxPayUtil.generateSignature(data, mchKey);
data.put("sign", sign);
// 调用统一下单API
String xmlResult = WxPayUtil.requestOnce("https://api.mch.weixin.qq.com/pay/unifiedorder", data);
Map<String, String> result = WxPayUtil.xmlToMap(xmlResult);
if ("SUCCESS".equals(result.get("return_code")) && "SUCCESS".equals(result.get("result_code"))) {
// 返回小程序支付参数
Map<String, String> payParams = new HashMap<>();
payParams.put("appId", appId);
payParams.put("timeStamp", String.valueOf(System.currentTimeMillis() / 1000));
payParams.put("nonceStr", WxPayUtil.generateNonceStr());
payParams.put("package", "prepay_id=" + result.get("prepay_id"));
payParams.put("signType", "MD5");
payParams.put("paySign", WxPayUtil.generateSignature(payParams, mchKey));
return payParams;
}
} catch (Exception e) {
throw new RuntimeException("微信支付下单失败", e);
}
throw new RuntimeException("微信支付下单失败");
}
// 支付回调处理
public String handleNotify(HttpServletRequest request) {
try {
String xmlData = IOUtils.toString(request.getInputStream(), StandardCharsets.UTF_8);
Map<String, String> data = WxPayUtil.xmlToMap(xmlData);
if (WxPayUtil.isSignatureValid(data, mchKey)) {
if ("SUCCESS".equals(data.get("result_code"))) {
// 更新订单状态
paymentOrderService.updateOrderStatus(
data.get("out_trade_no"),
"SUCCESS",
LocalDateTime.now()
);
// 更新用户VIP状态
userService.activateVip(data.get("out_trade_no"));
return "<xml><return_code><![CDATA[SUCCESS]]></return_code></xml>";
}
}
} catch (Exception e) {
// 处理异常
}
return "<xml><return_code><![CDATA[FAIL]]></return_code></xml>";
}
}
```
3. **控制器**
```java
// ParseController.java
@RestController
@RequestMapping("/api/parse")
public class ParseController {
@PostMapping("/process")
public ResponseEntity<ParseResult> processUrl(@RequestBody ParseRequest request) {
// 解析逻辑
ParseResult result = parseService.processUrl(request.getUrl(), request.getUserId());
return ResponseEntity.ok(result);
}
@GetMapping("/history/{userId}")
public ResponseEntity<List<ParseRecord>> getHistory(
@PathVariable Long userId,
@RequestParam(defaultValue = "0") int page,
@RequestParam(defaultValue = "10") int size) {
Page<ParseRecord> records = parseService.getUserRecords(userId, PageRequest.of(page, size));
return ResponseEntity.ok(records.getContent());
}
}
// PaymentController.java
@RestController
@RequestMapping("/api/payment")
public class PaymentController {
@PostMapping("/create")
public ResponseEntity<Map<String, String>> createVipOrder(@RequestBody PaymentRequest request) {
User user = userService.getUserById(request.getUserId());
Map<String, String> payParams = wxPayService.createOrder(
user,
"VIP会员",
request.getAmount()
);
return ResponseEntity.ok(payParams);
}
@PostMapping("/notify")
public String paymentNotify(HttpServletRequest request) {
return wxPayService.handleNotify(request);
}
}
// BannerController.java
@RestController
@RequestMapping("/api/banner")
public class BannerController {
@GetMapping("/active")
public ResponseEntity<List<Banner>> getActiveBanners() {
return ResponseEntity.ok(bannerService.getActiveBanners());
}
@PostMapping
@PreAuthorize("hasRole('ADMIN')")
public ResponseEntity<Banner> createBanner(@RequestBody Banner banner) {
return ResponseEntity.ok(bannerService.saveBanner(banner));
}
}
```

#### 核心页面
1. **首页 (Home.vue)**
```vue
<template>
<div class="home">
<!-- 轮播图 -->
<BannerSwiper :banners="banners" />
<!-- 解析区域 -->
<UrlParser @parse="handleParse" />
<!-- VIP开通提示 -->
<VipCard v-if="!user.isVip" @click="goToVip" />
</div>
</template>
<script>
import { ref, onMounted } from 'vue';
import { useStore } from 'vuex';
import { getActiveBanners } from '@/api/banner';
import BannerSwiper from '@/components/BannerSwiper.vue';
import UrlParser from '@/components/UrlParser.vue';
import VipCard from '@/components/VipCard.vue';
export default {
components: { BannerSwiper, UrlParser, VipCard },
setup() {
const store = useStore();
const banners = ref([]);
const user = ref(store.state.user);
onMounted(async () => {
banners.value = await getActiveBanners();
});
const handleParse = async (url) => {
const result = await parseUrl(url);
// 处理解析结果
};
const goToVip = () => {
// 跳转到VIP开通页面
};
return { banners, user, handleParse, goToVip };
}
};
</script>
```
2. **用户中心 (My.vue)**
```vue
<template>
<div class="my-page">
<div class="user-card">
<img :src="user.avatar" class="avatar" />
<div class="user-info">
<h3>{{ user.nickname }}</h3>
<p>用户ID: {{ user.id }}</p>
<p>解析次数: {{ user.parseCount }}</p>
<p v-if="user.isVip">VIP会员 (有效期至: {{ formatDate(user.vipExpire) }})</p>
<p v-else>普通用户</p>
</div>
</div>
<div class="actions">
<button @click="goToHistory">解析记录</button>
<button v-if="!user.isVip" @click="openVip">开通会员</button>
</div>
</div>
</template>
<script>
import { ref } from 'vue';
import { useStore } from 'vuex';
import { getUserDetail } from '@/api/user';
import { formatDate } from '@/utils/date';
export default {
setup() {
const store = useStore();
const user = ref(store.state.user);
// 获取用户详情
const fetchUserDetail = async () => {
const detail = await getUserDetail(user.value.id);
user.value = { ...user.value, ...detail };
store.commit('setUser', user.value);
};
const openVip = async () => {
// 调用支付接口
const paymentParams = await createVipOrder(29900); // 299元
// 调用微信支付
uni.requestPayment({
...paymentParams,
success: () => {
// 支付成功,更新用户状态
fetchUserDetail();
},
fail: (err) => {
console.error('支付失败', err);
}
});
};
const goToHistory = () => {
uni.navigateTo({ url: '/pages/History' });
};
return { user, formatDate, openVip, goToHistory };
}
};
</script>
```
3. **微信支付工具类 (wxpay.js)**
```javascript
import { createVipOrder } from '@/api/payment';
export const wxPay = {
payForVip: async (amount) => {
try {
const paymentParams = await createVipOrder(amount);
return new Promise((resolve, reject) => {
uni.requestPayment({
...paymentParams,
success: resolve,
fail: reject
});
});
} catch (error) {
console.error('支付创建失败', error);
throw error;
}
}
};
```
### 后台管理系统功能
1. **用户管理**
- 用户ID、昵称、头像
- 注册时间
- VIP状态及有效期
- 解析次数统计
2. **解析记录**
- 原始URL
- 解析结果URL

- 关联用户
3. **VIP管理**
- 微信支付对接
- 会员状态管理
- 支付订单跟踪
4. **轮播图管理**
- 图片上传
- 链接配置
- 排序控制
- 激活状态
### 部署配置
1. **微信支付配置 (application.yml)**
```yml
wxpay:
appId: wx1234567890abcdef # 小程序APPID
mchId: 1234567890 # 商户号
mchKey: your_mch_key # 商户API密钥
notifyUrl: https://yourdomain.com/api/payment/notify
```
2. **数据库配置**
```sql
CREATE TABLE users (
id BIGINT AUTO_INCREMENT PRIMARY KEY,
openid VARCHAR(100) NOT NULL UNIQUE,
nickname VARCHAR(100) NOT NULL,
avatar VARCHAR(500),
register_time DATETIME NOT NULL,
is_vip BOOLEAN DEFAULT false,
vip_expire DATETIME
);
CREATE TABLE parse_records (
id BIGINT AUTO_INCREMENT PRIMARY KEY,
user_id BIGINT NOT NULL,
original_url VARCHAR(1000) NOT NULL,
result_url VARCHAR(1000),
parse_time DATETIME NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id)
);
CREATE TABLE banners (
id BIGINT AUTO_INCREMENT PRIMARY KEY,
image_url VARCHAR(500) NOT NULL,
link_url VARCHAR(500),
sort_order INT DEFAULT 0,
active BOOLEAN DEFAULT true
);
CREATE TABLE payment_orders (
order_id VARCHAR(50) PRIMARY KEY,
user_id BIGINT NOT NULL,
amount INT NOT NULL,
status VARCHAR(20) DEFAULT 'CREATED',
create_time DATETIME NOT NULL,
pay_time DATETIME,
FOREIGN KEY (user_id) REFERENCES users(id)
);
```
### 前端转小程序说明
1. 使用HBuilderX的"发行->小程序"功能
2. 配置小程序APPID
3. 替换微信支付相关API调用
4. 调整UI组件适应小程序规范
