mybatis-plus在springmvc中的配置 java

好的，下面是mybatis-plus在springmvc中的配置：

1. 首先需要在pom.xml中添加mybatis-plus的依赖

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.4.3.1</version>
</dependency>

2. 在application.properties中配置数据源信息

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root

3. 创建实体类和Mapper接口

// 实体类
@Data
public class User {
    private Long id;
    private String name;
    private Integer age;
}

// Mapper接口
public interface UserMapper extends BaseMapper<User> {
}

4. 在Spring配置文件中配置MapperScannerConfigurer

@Configuration
public class MybatisPlusConfig {
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() {
        MapperScannerConfigurer configurer = new MapperScannerConfigurer();
        configurer.setBasePackage("com.example.mapper");
        return configurer;
    }
}

5. 最后在Controller中使用Mapper接口操作数据库

@RestController
public class UserController {
    @Autowired
    private UserMapper userMapper;
    
    @GetMapping("/users")
    public List<User> getUsers() {
        return userMapper.selectList(null);
    }
}

以上就是mybatis-plus在springmvc中的配置。
