我正在使用MybBatis并且我在 exnternal项目中遇到 ClassNotFound 错误，并且我在 resultMap中使用该类在一个 Mapper.xml 文件中 这是我的代码：
-Mapper.xml ：我只会将resultMapAquíssolocolocaréelresultMap放入，因为我遇到了问题。
<resultMap id="BaseResultMapGeneralConfig" type="classpath:com.iecisa.tecdoc.sirene.common.types.GeneralConfig">
<id column="id" jdbcType="NUMERIC" property="id" />
<result column="name" jdbcType="VARCHAR" property="name" />
<result column="value" jdbcType="VARCHAR" property="value" />
<result column="type" jdbcType="NUMERIC" property="type" />
</resultMap>
请注意，“type = com.etc ....”是外部项目中的类 - 我收到的错误代码：

我已在 Java Build Path 的项目标签中添加了我的主要项目中的外部项目，我还检查了外部项目检查订单和导出标签。
我尝试了不同的方法，比如没有“classpath：”这样的类，我没有找到解决方法。
任何的想法？我做错了什么？
谢谢你的帮助！
答案 0 :(得分：0)
我得到了解决方案。问题出在项目上。我的主要项目是Maven项目，但外部不是maven。 所以我只得到外部项目的.jar，通过maven在我的主项目中添加它，并依赖于pom.xml。
这就是全部，谢谢你的帮助！
