spring boot 集成 tk.mybatis 报错，反射方法异常

Question

spring boot 项目，想要集成 tk.mybatis框架。

使用的spring的快速配置：

pom.xml

<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>1.2.0</version>
</dependency>

---

application.yml

mapper:
  not-empty: false
  identity: MYSQL
  mappers:
    - online.yuyanjia.template.mobile.util.BaseMapper

---

其他的地方没有做配置，测试的时候报错

求大佬帮助！

Answer 1

我在SpringBoot集成Mybatis后使用通用Mapper的时候，也遇到了相同的问题

解决方式：在主程序中使用注解 @tk.mybatis.spring.annotation.MapperScan() 的形式来定义扫描mapper接口配置，然后重启

请参照 https://github.com/abel533/ma...

Answer 2

群里交流了下，替换版本后可以了。
<version>1.2.3</version>
pom.xml

<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper-spring-boot-starter</artifactId>
    <version>1.2.3</version>
</dependency>

低版本是用下面注解也可以

@tk.mybatis.spring.annotation.MapperScan

Answer 3

解决方案：

检查导入的包名 不是org 而是tk包

导入 import tk.mybatis.spring.annotation.MapperScan;
