Answer 1

XMLマッピングファイルにエラーがあります。行番号、列番号、エラーが存在するXML要素を示しています。

あなたのお手伝いをするためにXML設定ファイルを投稿してください（この質問の今後の検索でも参考にしてください）。

UPDATE

あなたは、このDTD宣言を含めると何が起こるかを見ることはできますか？

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
    "http://mybatis.org/dtd/mybatis-3-config.dtd"> 
<configuration> 

また、あなたが任意の隠された文字（複数可）を持っていないことを確認してください。
