基于javaweb+mysql的springboot学习平台管理系统(java+springboot+vue+elementui+layui+mysql+maven)

由于这个查询涉及的内容较多且不是单一的问题，我将提供一个简化的示例，展示如何使用Spring Boot和MyBatis结合MySQL数据库来创建一个简单的学习平台管理系统。

1. 创建数据库和表：

CREATE DATABASE learning_platform;
 
USE learning_platform;
 
CREATE TABLE user (
  id INT AUTO_INCREMENT PRIMARY KEY,
  username VARCHAR(50) NOT NULL,
  password VARCHAR(50) NOT NULL
);

2. 创建Spring Boot项目，并添加依赖：

<!-- pom.xml -->
<dependencies>
  <dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.4</version>
  </dependency>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
  <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
  </dependency>
  <!-- 其他依赖 -->
</dependencies>

3. 配置application.properties：

# application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/learning_platform?useSSL=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
mybatis.mapper-locations=classpath:mapper/*.xml

4. 创建User实体和Mapper接口：

// User.java
public class User {
  private Integer id;
  private String username;
  private String password;
  // getters and setters
}
 
// UserMapper.java
@Mapper
public interface UserMapper {
  User selectByUsername(String username);
  // 其他方法
}

5. 创建UserMapper的XML文件：

<!-- UserMapper.xml -->
<mapper namespace="com.example.mapper.UserMapper">
  <select id="selectByUsername" parameterType="String" resultType="com.example.entity.User">
    SELECT * FROM user WHERE username = #{username}
  </select>
  <!-- 其他SQL映射 -->
</mapper>

6. 创建Service和Controller：

// UserService.java
@Service
public class U
