Java版知识付费源码 Spring Cloud+Spring Boot+Mybatis+uniapp+前后端分离实现知识付费平台 +支持二次开发定制

**知识付费平台源码**

本文将介绍如何使用 Java 版 Spring Cloud、Spring Boot、Mybatis 等技术栈搭建一个知识付费平台。该平台将支持前后端分离的架构，并提供二次开发定制的功能。

###1.项目结构首先，我们需要定义项目的结构：

markdownknowledge-fee-platform├── knowledge-fee-platform-api (API接口模块)
├── knowledge-fee-platform-common (公共依赖模块)
├── knowledge-fee-platform-service (服务端模块)
│ ├── knowledge-fee-platform-service-web (Web层模块)
│ └── knowledge-fee-platform-service-core (业务逻辑模块)
└── knowledge-fee-platform-webapp (uniapp客户端模块)

###2. API接口模块在 `knowledge-fee-platform-api` 模块中，我们定义了知识付费平台的API接口：

java// knowledge-fee-platform-api/src/main/java/com/knowledge/fee/platform/api/KnowledgeFeePlatformApi.javapackage com.knowledge.fee.platform.api;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;

/**
 * @author [Your Name]
 */
@FeignClient(name = "knowledge-fee-platform-service")
public interface KnowledgeFeePlatformApi {

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 @GetMapping("/basicInfo")
 BasicInfo getBasicInfo();

 /**
 * 获取知识付费平台的课程列表 *
 * @param page页码 * @param size 每页大小 * @return 课程列表 */
 @GetMapping("/courses/{page}/{size}")
 CourseList getCourses(@PathVariable Integer page, @PathVariable Integer size);
}

###3.服务端模块在 `knowledge-fee-platform-service` 模块中，我们实现了知识付费平台的业务逻辑：

java// knowledge-fee-platform-service/src/main/java/com/knowledge/fee/platform/service/KnowledgeFeePlatformService.javapackage com.knowledge.fee.platform.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author [Your Name]
 */
@Servicepublic class KnowledgeFeePlatformService {

 private final KnowledgeFeePlatformDao knowledgeFeePlatformDao;

 @Autowired public KnowledgeFeePlatformService(KnowledgeFeePlatformDao knowledgeFeePlatformDao) {
 this.knowledgeFeePlatformDao = knowledgeFeePlatformDao;
 }

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 public BasicInfo getBasicInfo() {
 return knowledgeFeePlatformDao.getBasicInfo();
 }

 /**
 * 获取知识付费平台的课程列表 *
 * @param page页码 * @param size 每页大小 * @return 课程列表 */
 public CourseList getCourses(Integer page, Integer size) {
 return knowledgeFeePlatformDao.getCourses(page, size);
 }
}

###4. Web层模块在 `knowledge-fee-platform-service-web` 模块中，我们实现了知识付费平台的Web接口：

java// knowledge-fee-platform-service-web/src/main/java/com/knowledge/fee/platform/service/web/KnowledgeFeePlatformController.javapackage com.knowledge.fee.platform.service.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author [Your Name]
 */
@RestControllerpublic class KnowledgeFeePlatformController {

 private final KnowledgeFeePlatformService knowledgeFeePlatformService;

 @Autowired public KnowledgeFeePlatformController(KnowledgeFeePlatformService knowledgeFeePlatformService) {
 this.knowledgeFeePlatformService = knowledgeFeePlatformService;
 }

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 @GetMapping("/basicInfo")
 public BasicInfo getBasicInfo() {
 return knowledgeFeePlatformService.getBasicInfo();
 }

 /**
 * 获取知识付费平台的课程列表 *
 * @param page页码 * @param size 每页大小 * @return 课程列表 */
 @GetMapping("/courses/{page}/{size}")
 public CourseList getCourses(@PathVariable Integer page, @PathVariable Integer size) {
 return knowledgeFeePlatformService.getCourses(page, size);
 }
}

###5. uniapp客户端模块在 `knowledge-fee-platform-webapp` 模块中，我们实现了知识付费平台的uniapp客户端：

java// knowledge-fee-platform-webapp/src/main/java/com/knowledge/fee/platform/webapp/KnowledgeFeePlatformApp.javapackage com.knowledge.fee.platform.webapp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author [Your Name]
 */
@SpringBootApplicationpublic class KnowledgeFeePlatformApp {

 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformApp.class, args);
 }
}

###6. 公共依赖模块在 `knowledge-fee-platform-common` 模块中，我们定义了知识付费平台的公共依赖：

java// knowledge-fee-platform-common/src/main/java/com/knowledge/fee/platform/common/KnowledgeFeePlatformCommon.javapackage com.knowledge.fee.platform.common;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author [Your Name]
 */
@SpringBootApplicationpublic class KnowledgeFeePlatformCommon {

 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformCommon.class, args);
 }
}

###7. API接口模块在 `knowledge-fee-platform-api` 模块中，我们定义了知识付费平台的API接口：

java// knowledge-fee-platform-api/src/main/java/com/knowledge/fee/platform/api/KnowledgeFeePlatformApi.javapackage com.knowledge.fee.platform.api;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;

/**
 * @author [Your Name]
 */
@FeignClient(name = "knowledge-fee-platform-service")
public interface KnowledgeFeePlatformApi {

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 @GetMapping("/basicInfo")
 BasicInfo getBasicInfo();

 /**
 * 获取知识付费平台的课程列表 *
 * @param page页码 * @param size 每页大小 * @return 课程列表 */
 @GetMapping("/courses/{page}/{size}")
 CourseList getCourses(@PathVariable Integer page, @PathVariable Integer size);
}

###8.服务端模块在 `knowledge-fee-platform-service` 模块中，我们实现了知识付费平台的业务逻辑：

java// knowledge-fee-platform-service/src/main/java/com/knowledge/fee/platform/service/KnowledgeFeePlatformService.javapackage com.knowledge.fee.platform.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author [Your Name]
 */
@Servicepublic class KnowledgeFeePlatformService {

 private final KnowledgeFeePlatformDao knowledgeFeePlatformDao;

 @Autowired public KnowledgeFeePlatformService(KnowledgeFeePlatformDao knowledgeFeePlatformDao) {
 this.knowledgeFeePlatformDao = knowledgeFeePlatformDao;
 }

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 public BasicInfo getBasicInfo() {
 return knowledgeFeePlatformDao.getBasicInfo();
 }

 /**
 * 获取知识付费平台的课程列表 *
 * @param page页码 * @param size 每页大小 * @return 课程列表 */
 public CourseList getCourses(Integer page, Integer size) {
 return knowledgeFeePlatformDao.getCourses(page, size);
 }
}

###9. Web层模块在 `knowledge-fee-platform-service-web` 模块中，我们实现了知识付费平台的Web接口：

java// knowledge-fee-platform-service-web/src/main/java/com/knowledge/fee/platform/service/web/KnowledgeFeePlatformController.javapackage com.knowledge.fee.platform.service.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author [Your Name]
 */
@RestControllerpublic class KnowledgeFeePlatformController {

 private final KnowledgeFeePlatformService knowledgeFeePlatformService;

 @Autowired public KnowledgeFeePlatformController(KnowledgeFeePlatformService knowledgeFeePlatformService) {
 this.knowledgeFeePlatformService = knowledgeFeePlatformService;
 }

 /**
 * 获取知识付费平台的基本信息 *
 * @return 基本信息 */
 @GetMapping("/basicInfo")
 public BasicInfo getBasicInfo() {
 return knowledgeFeePlatformService.getBasicInfo();
 }

 /**
 * 获取知识付费平台的课程列表
