在IntelliJ IDEA中使用Spring Boot和MyBatis创建一个简单的教师和学生管理系统的步骤比较复杂,但我会提供一个概述和关键部分的代码片段。首先,你需要安装相关的依赖并设置项目结构。
1. **项目初始化**:
创建一个新的Spring Boot项目,选择Web作为启动依赖。然后添加Spring Data JPA和MyBatis支持:
```xml
<dependencies>
<!-- Spring Boot Web -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- Spring Data JPA -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<!-- MySQL Driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<!-- MyBatis -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
version=3.5.4
</dependency>
<!-- JPA Entity Manager -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<exclusions>
<exclusion>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.1-api</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- MyBatis Generator -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.7</version>
</dependency>
</dependencies>
```
2. **实体类(Entity)**:
设计Teacher和Student实体类:
```java
@Entity
public class Teacher {
@Id
private Long id;
private String name;
// getters and setters
}
@Entity
public class Student {
@Id
private Long id;
private String name;
@ManyToOne
private Teacher teacher; // 如果有导师关联
// getters and setters
}
```
3. **Mapper接口(Mapper Interface)**:
定义TeacherMapper和StudentMapper接口,包含CRUD操作:
```java
public interface TeacherMapper {
Teacher selectTeacherById(Long id);
void insertTeacher(Teacher teacher);
void updateTeacher(Teacher teacher);
void deleteTeacherById(Long id);
List<Teacher> getAllTeachers();
}
public interface StudentMapper {
Student selectStudentById(Long id);
void insertStudent(Student student);
void updateStudent(Student student);
void deleteStudentById(Long id);
List<Student> getAllStudents();
}
```
4. **配置文件(application.properties)**:
配置数据库连接信息:
```properties
spring.datasource.url=jdbc:mysql://localhost:3306/db_name
spring.datasource.username=root
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update
```
5. **Service层(Service Class)**:
实现业务逻辑和服务方法。
6. **Controller层(Controller Class)**:
使用@Autowired注入Mapper,并编写HTTP请求对应的处理方法。
由于篇幅原因,这里无法给出完整的代码,但上述步骤为你提供了创建这样一个系统的指导。实际代码需要在上述基础上逐步完成,包括数据生成器的配置和运行、事务管理、异常处理等细节。以下是几个相关的问题供你参考:
