一、背景描述

最近新创建一个Spring boot (v2.0.0.RELEASE) + mybatis plus (3.1.1 RELEASE)项目，在测试接口时，IDEA控制台居然报错，报错信息：

在实现类ServiceImpl中的代码如下：

每次调用此接口时（或者使用相同方式写的代码都会出现，CRUD操作都一样出现），详细的报错信息，我放到文章的最后，有兴趣的可以查看。

二、错误原因

针对3.1.1以及后面的版本：

现象：单元测试没问题，启动服务器进行调试就出现这个问题

原因： dev-tools, 3.1.1+针对字段缓存，使用.class来作为key替换了原来的className, 而使用dev-tools会把.class使用不同的classLoader加载，导致可能出现找不到的情况

三、解决方案

解决方案很简单，在 pom.xml文件中把 devtools依赖注释掉 或者 删除此依赖 即可。

去掉dev-tools插件

注：此解决方案为Mybatis-Plus官方推荐的方式，详情可查看 Mybatis-Plus FAQ 常见问题。

完结！以下是报错的详情信息，有兴趣的可以查看一下哦：
