.ibatis.binding.BindingException: Invalid bound statement (not found): com.taotao.mapper.TbItemMapper是什么意思？有什么可能的原因导致这个异常出现？
回答: 引用中的异常报告表示请求处理失败，其中的org.apache.ibatis.binding.BindingException异常是无效的绑定语句（未找到）：com.taotao.mapper.TbItemMapper。这个异常通常是由于无效的语句映射或者找不到语句映射引起的。可能的原因包括语句映射文件中的错误语句ID、映射接口方法名与映射文件中的ID不匹配、或者映射文件中找不到对应的语句映射。在这种情况下，需要检查语句映射文件中的语句ID是否正确，以及映射接口方法是否与映射文件中的ID一致。同时，还需要确认映射文件中是否存在对应的语句映射。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
