Answer 1

自动注入出错了，你的HsbAccAlarmRecordMapper这个类没有交给Spring容器进行管理

Answer 2

异常原因是在spring-global.xml引用了多个数据源：
<import resource="classpath:spring/spring-datasource.xml" />
 <import resource="classpath:spring/ac-spring-datasource.xml" />
其中一个*datasource.xml文件的自动扫描映射器,里面缺少“ <property name="sqlSessionFactoryBeanName" value="acSqlSessionFactory"/>”导致启动报错。
解决方法：
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" > 
        <property name="sqlSessionFactoryBeanName" value="acSqlSessionFactory"/>   
        <property name="basePackage" value="com.ac.mapper" />  
    </bean>
<!-- 创建SqlSessionFactory -->
    <bean id="acSqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="acDataSource" />  
        <property name="mapperLocations" value="classpath*:com/**/*Mapper.xml"/>
         <property name="typeAliasesPackage" value="com.alarm.bean" />  
    </bean>
