Java “线程中的异常”；“主要”；org.apache.ibatis.exceptions.IbatisException

这是我第一次在Mybatis上工作。我正在尝试创建连接，但出现以下错误

Exception in thread "main" org.apache.ibatis.exceptions.IbatisException:

有人能帮我解决这个错误吗？

您的XML映射文件中有一个错误；它告诉您错误所在的行号、列号和XML元素

发布XML配置文件以帮助您（也可供将来搜索此问题时参考）

更新

您能包括这个DTD声明并看看会发生什么吗

<?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>

此外，请确保您没有任何隐藏的角色。

您好，欢迎使用SO！请尝试添加显示该错误的代码，以便我们可以看到代码的哪一部分出错。是否也可以包含

mybatis config.xml

？我已包含在底部。感谢这应该是一个注释在更新配置文件中的DTD后，我收到以下错误原因：org.apache.ibatis.builder.BuilderException:解析SQL映射器配置时出错。原因：java.io.IOException:找不到资源/booker.xml我认为这是路径问题。我认为是

booker.xml

中的

namespace

属性；尝试使用该类的包名：

。
