spring怎么整合mybatis源碼

整合Spring和MyBatis的源碼可以分為以下幾個(gè)步驟：

1. 添加MyBatis和Spring的依賴：在項(xiàng)目的pom.xml文件中添加MyBatis和Spring的依賴，例如：

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.5.7</version>
</dependency>

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>2.0.5</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.3.8</version>
</dependency>

2. 配置MyBatis的SqlSessionFactoryBean：在Spring的配置文件中配置MyBatis的SqlSessionFactoryBean，例如：

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="mapperLocations" value="classpath:mapper/*.xml" />
</bean>

3. 配置MyBatis的MapperScannerConfigurer：在Spring的配置文件中配置MyBatis的MapperScannerConfigurer，例如：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.example.mapper" />
</bean>

4. 編寫Mapper接口和映射文件：編寫Mapper接口和對應(yīng)的映射文件，例如：

public interface UserMapper {
    User getUserById(Long id);
}

<!-- UserMapper.xml -->
<mapper namespace="com.example.mapper.UserMapper">
    <select id="getUserById" resultType="com.example.model.User">
        SELECT * FROM user WHERE id = #{id}
    </select>
</mapper>

5. 在Service中注入Mapper接口：在Service中注入Mapper接口并調(diào)用其方法，例如：

@Service
public class UserService {
    
    @Autowired
    private UserMapper userMapper;
    
    public User getUserById(Long id) {
        return userMapper.getUserById(id);
    }
}

通過以上步驟，就可以實(shí)現(xiàn)Spring和MyBatis的整合，實(shí)現(xiàn)數(shù)據(jù)訪問功能。
