好的,关于培训班学员信息管理的Spring Boot+MyBatis配置,我可以给您提供一些具体的步骤和代码实现。
1. 配置pom.xml文件
在pom.xml文件中添加以下依赖:
```
<dependencies>
<!-- Spring Boot Web 依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- MyBatis 依赖 -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.3</version>
</dependency>
<!-- MySQL 连接驱动 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.25</version>
</dependency>
</dependencies>
```
2. 配置application.properties文件
在application.properties文件中添加以下配置:
```
# 数据库配置
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
# MyBatis 配置
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.entity
```
3. 创建实体类
在com.example.demo.entity包下创建学员信息实体类,例如:
```
public class Student {
private Long id;
private String name;
private Integer age;
private String gender;
private String phone;
// 省略 getter 和 setter 方法
}
```
4. 创建Mapper接口
在com.example.demo.mapper包下创建学员信息Mapper接口,例如:
```
@Mapper
public interface StudentMapper {
@Select("SELECT * FROM student WHERE id = #{id}")
Student findById(Long id);
@Insert("INSERT INTO student(name, age, gender, phone) VALUES(#{name}, #{age}, #{gender}, #{phone})")
void insert(Student student);
@Update("UPDATE student SET name = #{name}, age = #{age}, gender = #{gender}, phone = #{phone} WHERE id = #{id}")
void update(Student student);
@Delete("DELETE FROM student WHERE id = #{id}")
void delete(Long id);
}
```
5. 创建Service层
在com.example.demo.service包下创建学员信息Service层,例如:
```
@Service
public class StudentService {
@Autowired
private StudentMapper studentMapper;
public Student findById(Long id) {
return studentMapper.findById(id);
}
public void insert(Student student) {
studentMapper.insert(student);
}
public void update(Student student) {
studentMapper.update(student);
}
public void delete(Long id) {
studentMapper.delete(id);
}
}
```
6. 创建Controller层
在com.example.demo.controller包下创建学员信息Controller层,例如:
```
@RestController
@RequestMapping("/student")
public class StudentController {
@Autowired
private StudentService studentService;
@GetMapping("/{id}")
public Student findById(@PathVariable Long id) {
return studentService.findById(id);
}
@PostMapping("")
public void insert(@RequestBody Student student) {
studentService.insert(student);
}
@PutMapping("")
public void update(@RequestBody Student student) {
studentService.update(student);
}
@DeleteMapping("/{id}")
public void delete(@PathVariable Long id) {
studentService.delete(id);
}
}
```
以上就是基于Spring Boot和MyBatis的培训班学员信息管理配置的具体步骤和代码实现,您可以参考并根据自己的需求进行修改。
