SpringBoot集成Mybatis时无法扫描Mapper问题

使用mybatis官方提供的starter与SpringBoot做整合

<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>

在IDE中启动项目没有问题，但当打成JAR启动项目时出现以下异常:

15:51:43.909 [main] DEBUG o.s.b.d.LoggingFailureAnalysisReporter - Application failed to start due to an exception
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [org.zbt.service.jxc.dao.base.DataDicMapper]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1463)

org.springframework.boot.starter.dubbo.startup.BootStrap.main(BootStrap.java:15)
2016-11-13 15:51:44.389 ERROR 3349 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter

由异常可以知道是因为Mapper没有SpringBoot扫描到。

而官方提供的可配置参数只有以几个：

config-location MyBatis xml config file (optional)
mapper-locations    Mapper xml config files (optional)
type-aliases-package    Package to search for type aliases (optional)
type-handlers-package   Package to search for type aliases (optional)
executor-type   Executor type: SIMPLE, REUSE, BATCH (optional)
configuration   A MyBatis Configuration bean

可以看出无法指定Mapper接口的位置。

可以通过在可以被SpringBoot加载到的spring文件中加入以下配置来解决这一个问题：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >
<property name="basePackage" value="org.zbt.service.jxc.dao.base"/>
<property name="annotationClass" value="org.apache.ibatis.annotations.Mapper"/>
</bean>
