</beans>

三、Spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"

    </bean>


    <!-- 配置基于注解的声明式事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
</beans>

二、Mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

jdbc.username=root
jdbc.password=123456

五、log4j.properties

log4j.rootLogger=INFO,console,dailyFile
# TODO 发布到阿里云记得添加，另外控制台不输出(只输出warn或者error信息)
#INFO,console,dailyFile

log4j.logger.org.mybatis =DEBUG
log4j.logger.com.itzixi.mapper=DEBUG

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.encoding=UTF-8
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%l] - [%p] %m%n
#mybatis显示SQL语句日志配置
#log4j.logger.org.mybatis=DEBUG
#log4j.logger.com.itzixi.mapper=DEBUG

# 定期滚动日志文件，每天都会生成日志
log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.dailyFile.encoding=UTF-8
log4j.appender.dailyFile.Threshold=INFO
# TODO 本地日志地址，正式环境请务必切换为阿里云地址
log4j.appender.dailyFile.File=F:/log4j/rizhi/log.txt
#log4j.appender.dailyFile.File=/itzixi-disk1/logs/itzixi-web/log.log4j
log4j.appender.dailyFile.DatePattern='.'yyyy-MM-dd
log4j.appender.dailyFile.layout=org.apache.log4j.PatternLayout
log4j.appender.dailyFile.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%l] - [%p] %m%n


##显示SQL语句部分
#log4j.logger.com.ibatis=DEBUG
#log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
#log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
#log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
#log4j.logger.java.sql.Connection=DEBUG
#log4j.logger.java.sql.Statement=DEBUG
#log4j.logger.java.sql.PreparedStatement=DEBUG

六、Mapper文件中xml写法(例：UserMapper.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="com.dao.UserDao">
    <resultMap type="User" id="UserResultMap">
        <id property="Id" column="Id"/>
        <result property="UserName" column="UserName"/>
        <result property="UserPassword" column="UserPassword"/>
        <result property="UserPhone" column="UserPhone"/>
        <result property="UserPhoto" column="UserPhoto"/>
        <result property="UserMailbox" column="UserMailbox"/>
        <result property="UserIdCard" column="UserIdCard"/>
        <result property="UserTime" column="UserTime"/>
    </resultMap>
    <!--初始化数据-->
    <select id="AllUserDao" resultMap="UserResultMap">
        SELECT Id,UserName,UserPassword,UserPhone,UserPhoto,UserMailbox,UserIdCard,UserTime FROM user_sc
    </select>
    <!--修改-->
    <update id="ModelDao" parameterType="User">
        UPDATE user_sc
        SET UserName = #{UserName},UserPassword = #{UserPassword},UserPhone = #{UserPhone},UserPhoto = #{UserPhoto},UserMailbox = #{UserMailbox},UserIdCard = #{UserIdCard}
        WHERE  Id = #{Id}
    </update>
    <!--修改所查询的一条数据-->
    <select id="QueryDaoId" resultType="User" parameterType="int">
        SELECT Id,UserName,UserPassword,UserPhone,UserPhoto,UserMailbox,UserIdCard FROM user_sc WHERE Id = #{id}
    </select>
    <!--添加-->
    <insert id="AddUserDao" parameterType="User">
        INSERT INTO user_sc(UserName,UserPassword,UserPhone,UserPhoto,UserMailbox,UserIdCard,UserTime) VALUE (#{UserName},#{UserPassword},#{UserPhone},#{UserPhoto},#{UserMailbox},#{UserIdCard},#{UserTime})
    </insert>
    <!--删除-->
    <delete id="DelDao" parameterType="int">
         DELETE FROM user_sc WHERE Id=#{id}
    </delete>
    <!--批量删除-->
    <delete id="DelNumberDao" parameterType="int">
         DELETE FROM user_sc WHERE Id = #{data}
    </delete>
    <!--模糊查询-->
    <select id="QueryDao" parameterType="String" resultMap="UserResultMap">
        SELECT Id,UserName,UserPassword,UserPhone,UserPhoto,UserMailbox,UserIdCard,UserTime FROM user_sc
        <where>
            <if test="key!=null and key!=''">
                UserName like concat('%',#{key},'%')
            </if>
        </where>
    </select>
    <!--初始化数据 根据分页数据start 和size查询数据 -->
    <sql id="UserCon">
		Id,UserName,UserPassword,UserPhone,UserPhoto,UserMailbox,UserIdCard,UserTime
	</sql>
    <select id="findByPage" parameterType="User" resultMap="UserResultMap">
        select
        <include refid="UserCon"/>
        from user_sc
        <where>
            <if test="rname!=null and rname!=''">
                UserName like concat('%',#{rname},'%')
            </if>
        </where>
        limit #{start},#{pageSize}
    </select>
    <!-- 查询用户记录总数 -->
    <select id="findTotalCount" resultType="int">
        select count(*) from user_sc
        <where>
            <if test="rname!=null and rname!=''">
                UserName like concat('%',#{rname},'%')
            </if>
        </where>
    </select>
    <!--登录-->
    <select id="LoginDao" resultMap="UserResultMap">
        SELECT * FROM user_sc where UserName= #{UserName}  and UserPassword = #{UserPassword}
    </select>
</mapper>

七、web.xml

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1" metadata-complete="true">
    <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 配置springMVC需要加载的配置文件
            spring-dao.xml,spring-service.xml,spring-mvc.xml
            Mybatis - > spring -> springmvc
         -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-*.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <!-- 默认匹配所有的请求 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>
