当然有!MyBatis Plus 和 Spring Boot 整合的一种具体方案如下:
1. 在项目中引入 MyBatis Plus 的依赖:
```
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.4.0</version>
</dependency>
```
2. 在配置文件中配置数据源和 MyBatis Plus 的相关信息:
```
# 数据源配置
spring:
datasource:
url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
username: root
password: root
driver-class-name: com.mysql.cj.jdbc.Driver
# MyBatis Plus 配置
mybatis-plus:
mapper-locations: classpath:/mapper/**Mapper.xml
type-aliases-package: com.example.demo.entity
```
3. 在实体类上添加注解:
```
@Data
@TableName("user")
public class User {
@TableId(type = IdType.AUTO)
private Long id;
private String name;
private Integer age;
private String email;
}
```
4. 创建 Mapper 接口:
```
public interface UserMapper extends BaseMapper<User> {
}
```
5. 创建 Service 和 ServiceImpl 层:
```
public interface UserService {
List<User> list();
}
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public List<User> list() {
return userMapper.selectList(null);
}
}
```
这样,MyBatis Plus 就成功地和 Spring Boot 整合在了一起!
