本文介绍了一种在使用MyBatis时遇到的Dao配置问题及其解决方案。问题出现在尝试加载DAO配置文件时，具体表现为找不到必要的类定义，文中详细记录了错误堆栈跟踪，并寻求帮助。

DaoConfig:

public class DaoConfig {
  
 public static DaoManager getDaoManagerInstance() {
  DaoManager daoManager = null;
  try {
   String resource ="com/jxgl/persistence/sqlmapdao/config/dao.xml";
   Reader reader = Resources.getResourceAsReader(resource);
   daoManager = DaoManagerBuilder.buildDaoManager(reader);
  } catch (IOException e) {
   throw new RuntimeException("未能初始化数据库--" + DaoConfig.class);
  }
  return daoManager;
 }
}

当我调试到:daoManager = DaoManagerBuilder.buildDaoManager(reader);的时候

就会出现错误!

Class File Editor

The source attachment does not contain the source for Class.class

错误信息：

强大的数据库ORM框架-GreenDao增删改查篇
老蒋也疯狂

“前两篇博文分别阐述了如何去搭建一个GreenDao框架项目和剖析了项目中的相关源码，这让我们对GreenDao框架有了初步的了解以及如何去使用它，那么接下来就来了解GreenDao框架是如何能够在不接触SQL语句的情况下实现对本地数据库的增删改查。”由之前的博文可知，使用GreenDao框架对本地数据库的增删改查最终是通过GreenDao生成器自动生成的xxxDao类实现的(如PersonInfoDao、WorkInfoDao)，它们封装了大部分数据库操作方法，通常一张表就对应一个xxxDao类。

没开启混淆前是没有问题的，开启混淆后就报错了。结合litepal需要添加混淆规则和平时bean类也需要加@Keep注解防止混淆，于是乎就感觉是混淆需要配置。以前遇到过，解决了，但是没有记载，这次自己记载一下.重新运行就解决了！
