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

**知识付费平台源码**

本文将介绍如何使用 Java 版的 Spring Cloud、Spring Boot、MyBatis 等技术栈搭建一个知识付费平台。我们将实现前后端分离，使用 uniapp 作为移动端客户端。

###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 (Spring Boot API)
├── knowledge-fee-platform-service (Spring Cloud Service)
├── knowledge-fee-platform-web (Spring Web 前端)
├── knowledge-fee-platform-mobile (uniapp 移动端客户端)
└── knowledge-fee-platform-common (共享模块)

###2. knowledge-fee-platform-api这是我们的 API 模块，负责提供接口给前端和移动端使用。我们将使用 Spring Boot 来构建这个模块。

**pom.xml**

xml<dependencies>
 <!-- Spring Boot -->
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>

 <!-- MyBatis -->
 <dependency>
 <groupId>org.mybatis.spring.boot</groupId>
 <artifactId>mybatis-spring-boot-starter</artifactId>
 </dependency>

 <!-- MySQL Connector -->
 <dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 </dependency>
</dependencies>

**application.properties**

propertiesspring.datasource.url=jdbc:mysql://localhost:3306/knowledge_fee_platformspring.datasource.username=rootspring.datasource.password=123456mybatis.mapper-locations=classpath:mappers/*.xml

**KnowledgeFeePlatformApiApplication.java**

java@SpringBootApplicationpublic class KnowledgeFeePlatformApiApplication {
 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformApiApplication.class, args);
 }
}

###3. knowledge-fee-platform-service这是我们的服务模块，负责提供接口给 API 模块使用。我们将使用 Spring Cloud 来构建这个模块。

**pom.xml**

xml<dependencies>
 <!-- Spring Cloud -->
 <dependency>
 <groupId>org.springframework.cloud</groupId>
 <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
 </dependency>

 <!-- API 模块的依赖 -->
 <dependency>
 <groupId>com.example</groupId>
 <artifactId>knowledge-fee-platform-api</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 </dependency>
</dependencies>

**application.properties**

propertieseureka.client.service-url.defaultZone= />

**KnowledgeFeePlatformServiceApplication.java**

java@SpringBootApplication@EnableEurekaClientpublic class KnowledgeFeePlatformServiceApplication {
 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformServiceApplication.class, args);
 }
}

###4. knowledge-fee-platform-web这是我们的前端模块，负责提供网页接口给用户使用。我们将使用 Spring Web 来构建这个模块。

**pom.xml**

xml<dependencies>
 <!-- Spring Web -->
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>

 <!-- API 模块的依赖 -->
 <dependency>
 <groupId>com.example</groupId>
 <artifactId>knowledge-fee-platform-api</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 </dependency>
</dependencies>

**application.properties**

propertiesspring.datasource.url=jdbc:mysql://localhost:3306/knowledge_fee_platformspring.datasource.username=rootspring.datasource.password=123456mybatis.mapper-locations=classpath:mappers/*.xml

**KnowledgeFeePlatformWebApplication.java**

java@SpringBootApplicationpublic class KnowledgeFeePlatformWebApplication {
 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformWebApplication.class, args);
 }
}

###5. knowledge-fee-platform-mobile这是我们的移动端客户端模块，负责提供移动端接口给用户使用。我们将使用 uniapp 来构建这个模块。

**uni-app.config.js**

javascriptmodule.exports = {
 // ...
 pages: {
 index: 'pages/index/index',
 // ...
 },
};

**index.vue**

vue<template>
 <!-- ... -->
</template>

<script>
export default {
 // ...
}
</script>

###6. knowledge-fee-platform-common这是我们的共享模块，负责提供公共功能给其他模块使用。我们将使用 Spring Boot 来构建这个模块。

**pom.xml**

xml<dependencies>
 <!-- Spring Boot -->
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>

 <!-- MyBatis -->
 <dependency>
 <groupId>org.mybatis.spring.boot</groupId>
 <artifactId>mybatis-spring-boot-starter</artifactId>
 </dependency>

 <!-- MySQL Connector -->
 <dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 </dependency>
</dependencies>

**application.properties**

propertiesspring.datasource.url=jdbc:mysql://localhost:3306/knowledge_fee_platformspring.datasource.username=rootspring.datasource.password=123456mybatis.mapper-locations=classpath:mappers/*.xml

**KnowledgeFeePlatformCommonApplication.java**

java@SpringBootApplicationpublic class KnowledgeFeePlatformCommonApplication {
 public static void main(String[] args) {
 SpringApplication.run(KnowledgeFeePlatformCommonApplication.class, args);
 }
}

以上就是我们使用 Java 版的 Spring Cloud、Spring Boot、MyBatis 等技术栈搭建一个知识付费平台的步骤。
