1、错误描述

XML Parser Errors
  See Details for more Information
  XML Parser Error on line 1: Document root element "generatorConfiguration",must match DOCTYPE root "null".
  XML Parser Error on line 1: Document is invalid: no grammar found.

2、错误原因

generatorConfig.xml以<generatorConfiguration> 开头，没有正确配置头部

3、解决办法

在上述<generatorConfiguration>头部添加如下代码：

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