请阅读以下代码:<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.example.demo.mapper.UserMapper"> <resultMap id="userMap" type="com.example.demo.model.User"> <id property="id" column="id" /> <result property="name" column="name" /> <result property="email" column="email" /> </resultMap> <select id="findAll" resultMap="userMap"> SELECT * FROM user </select> <select id="findById" resultMap="userMap"> SELECT * FROM user WHERE id = #{id} </select> <insert id="save"> INSERT INTO user(name, email) VALUES (#{name}, #{email}) </insert> <update id="update"> UPDATE user SET name=#{name}, email=#{email} WHERE id=#{id} </update> <delete id="delete"> DELETE FROM user WHERE id=#{id} </delete> <configuration> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> </configuration> </mapper> 如果我使用的不是hibernate框架,应当怎么修改?

如果您不使用 Hibernate 框架,则需要将 `<configuration>` 元素与其中的 `<property>` 元素从代码中删除。这是因为 `<configuration>` 元素和 `<property>` 元素是 Hibernate 框架特有的配置项,如果您不使用 Hibernate,则不需要这些配置。
因此,您可以将以下代码作为您不使用 Hibernate 框架的 MyBatis 映射器 XML 文件的示例:
```
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.demo.mapper.UserMapper">
<resultMap id="userMap" type="com.example.demo.model.User">
<id property="id" column="id" />
<result property="name" column="name" />
<result property="email" column="email" />
</resultMap>
<select id="findAll" resultMap="userMap">
SELECT * FROM user
</select>
<select id="findById" resultMap="userMap">
SELECT * FROM user WHERE id = #{id}
</select>
<insert id="save">
INSERT INTO user(name, email) VALUES (#{name}, #{email})
</insert>
<update id="update">
UPDATE user SET name=#{name}, email=#{email} WHERE id=#{id}
</update>
<delete id="delete">
DELETE FROM user WHERE id=#{id}
</delete>
</mapper>
```
请注意,在这种情况下,您需要将适当的 JDBC 配置添加到您的应用程序中,以确保 MyBatis 可以连接到您的数据库。
