我创建了一个selma示例，但无法生成代码。在运行时，会出现一个错误

Caused by: java.lang.ClassNotFoundException:com.mapper.mapper.SelmaMapperSelmaGeneratedClass

是否需要添加其他配置来生成代码？

Answer 1

我误解了编译时间的含义，实际上，我应该运行maven命令清理安装。然后生成代码。

Answer 2

要在没有Maven的eclipse中使用Selma，您应该将处理器和api jar添加到批注处理器插件的路径中。这应该在项目设置中的某个位置，请参阅插件文档： https://www.eclipse.org/jdt/apt/introToAPT.php 。
