# 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：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI5OTAyNw_size_16_color_FFFFFF_t_70][]

在实现类ServiceImpl中的代码如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI5OTAyNw_size_16_color_FFFFFF_t_70 1][]

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。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI5OTAyNw_size_16_color_FFFFFF_t_70 2][]

# 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][Mybatis-Plus FAQ]。

完结！以下是报错的详情信息，有兴趣的可以查看一下哦：
