XML Parser Error on line 3: 文档根元素 "generatorConfiguration" 必须匹配 DOCTYPE 根 "configuration"。

回答: 这个错误是由于XML文件中的文档根元素"generatorConfiguration"与DOCTYPE根"configuration"不匹配所导致的。\[1\]要解决这个问题，你需要确保XML文件中的文档根元素与DOCTYPE根相匹配。在你的XML文件中，你需要将文档根元素改为"configuration"，并确保DOCTYPE根与之匹配。你可以在文件开头添加以下代码来修复这个错误:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

这样做可以确保文档根元素与DOCTYPE根相匹配，从而解决XML Parser Error on line 3的问题。\[2\]\[3\]
