运行Javaweb项目的时候出现这个问题

problem：Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginMapper' defined in file [G:\2017课程设计\cherry\project_manager\out\artifacts\project_manager_war_exploded\WEB-INF\classes\spring\spring-mybatis.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'mapperInterface ' of bean class [org.mybatis.spring.mapper.MapperFactoryBean]: Bean property 'mapperInterface ' is not writable or has an invalid setter method. Did you mean 'mapperInterface'?

我检查了很久，添加了之前有人说的default-autowire="byName"，没用，也检查了数据库的链接，发现和数据库暂时没有关系，

但是我注意到了 not writable or has an invalid setter method，我又重新检查了我的配置文件发现

<bean id="loginMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface " value="com.electric.mappers.LoginMapper"></property>
    <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
