mybatis异常：There is no getter for property named 'xxx' in 'xxx'

在使用mybatis查询的时候出现了下面的异常：

org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'dictType' in 'class com.up.sell.vo.system.Advertisement'
    at org.apache.ibatis.reflection.Reflector.getGetInvoker(Reflector.java:419) ~[mybatis-3.4.6.jar:3.4.6]
    at org.apache.ibatis.reflection.MetaClass.getGetInvoker(MetaClass.java:164) ~[mybatis-3.4.6.jar:3.4.6]
    at org.apache.ibatis.reflection.wrapper.BeanWrapper.getBeanProperty(BeanWrapper.java:162) ~[mybatis-3.4.6.jar:3.4.6]
    at org.apache.ibatis.reflection.wrapper.BeanWrapper.get(BeanWrapper.java:49) ~[mybatis-3.4.6.jar:3.4.6]
    at org.apache.ibatis.reflection.MetaObject.getValue(MetaObject.java:122) ~[mybatis-3.4.6.jar:3.4.6]

这个错误的原因是我的resultMap大小写写错了，大家做好看一下实体中的字段和mapper中的大小写，别搞反。

贴上代码，可以参照一下：

    <resultMap type="Advertisement" id="AdvertisementResult">
        <id property="id" column="id" />
        <result property="title" column="title" />
        <result property="imgPath" column="img_path" />
        <result property="url" column="url" />
