最近在使用mybatis generator 工具自動生成一個dao層對映時，報如下錯誤，不知如果debug，求指導~

具體配置檔案如下：

<?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">
<generatorConfiguration>

	<context id="myTables" targetRuntime="MyBatis3">

			<property name="suppressAllComments" value="true" />
		</commentGenerator>

		<javaTypeResolver>

		</javaTypeResolver>
		
		<!--生成Model類存放位置 -->

		<javaClientGenerator type="XMLMAPPER"

		</javaClientGenerator>
		
		<!--生成對應表及類名 -->
		<table schema="root" tableName="message" domainObjectName="Messgae"
			enableCountByExample="false" enableUpdateByExample="false"
			enableDeleteByExample="false" enableSelectByExample="false"
			selectByExampleQueryId="false"></table>
	</context>

</generatorConfiguration>
 

其他blog所寫的解決辦法似乎都沒有效果。。。
