解决方案

1. 检查xml的namespace是否与mapper里面的接口名一致

 <mapper namespace="com.zking.ssm.mapper.LogininfoMapper">

2. 检查mapper中xml的配置是否正确

 <property name="mapperLocations" value="classpath*:/mapper/*.xml"/>

3.我报错是因为在prom.xml中多写了逆向生成的代码

<!--<resources>-->
      <!--&lt;!&ndash;解决mybatis-generator-maven-plugin运行时没有将XxxMapper.xml文件放入target文件夹的问题&ndash;&gt;-->
      <!--<resource>-->
        <!--<directory>src/main/java</directory>-->
        <!--<includes>-->
          <!--<include>**/*.xml</include>-->
        <!--</includes>-->
      <!--</resource>-->
      <!--&lt;!&ndash;解决mybatis-generator-maven-plugin运行时没有将jdbc.properites文件放入target文件夹的问题&ndash;&gt;-->
      <!--<resource>-->
        <!--<directory>src/main/resources</directory>-->
        <!--<includes>-->
          <!--<include>jdbc.properties</include>-->
          <!--<include>*.xml</include>-->
        <!--</includes>-->
      <!--</resource>-->
    <!--</resources>-->

因为我在spring的配置文件中以及配置过了，然后删掉逆向生成的代码就好了

<!--4. spring和MyBatis整合 -->
    <!--1) 创建sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 指定数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 指定mybatis核心配置文件 -->
        <property name="configLocation" value="classpath:mybatis.cfg.xml"/>
        <!-- 自动扫描XxxMapping.xml文件，**表示迭代查找 -->
        <property name="mapperLocations" value="classpath*:/mapper/*.xml"/>
    </bean>

    <!--2) 自动扫描com/zking/oa/**/mapper下的所有XxxMapper接口(其实就是DAO接口)，并实现这些接口-->
    <!--   即可直接在程序中使用dao接口，不用再获取sqlsession对象-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--basePackage 属性是映射器接口文件的包路径。-->
        <!--你可以使用分号或逗号 作为分隔符设置多于一个的包路径-->
        <property name="basePackage" value="com/zking/**/mapper"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>
