工程大致結構：
project
|-src
|----pojo
|--------Temp.java
|----dao
|--------TempDao.java
|--------TempDao.xml
|----web
|--------TempController.java
|-resources
|----applicationContext.xml
|----springMVC.xml
|----mybatis-config.xml
|----db.properties
|----log4j.properties
|-webapp
|----WEB-INF
|--------web.xml
|-pom.xml
pom.xml引入依賴：

再來，有java類TempDao、Temp：
public interface TempDao {
Temp findTempById(int id);
int insertTemp(Temp temp);
int deleteTempById(int id);
List<Temp> findTemps();
int updateTemp(Temp temp);
}
public class Temp {
private int id;
private String name;
private String sex;
private String text;
//setter & getter
}TempDao.xml
<?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="dao.TempDao">
<select id="findTempById" parameterType="int" resultType="Temp">
SELECT * FROM tb_temp WHERE id = #{id}
</select>
<insert id="insertTemp" parameterType="Temp">
INSERT INTO tb_temp(username, sex, text) VALUES(#{username}, #{sex}, #{text})
</insert>
<delete id="deleteTempById" parameterType="int">
DELETE FROM tb_temp WHERE id = #{id}
</delete>
<select id="findTemps" resultType="Temp">
SELECT * FROM tb_temp
</select>
<update id="updateTemp" parameterType="Temp">
UPDATE tb_temp SET username = #{username}, sex = #{sex} WHERE id = #{id}
</update>
</mapper>
