mappers 参数错误导致的。升级到 2.0.1 或者配置 mappers 都能解决。
就是2.0.1的。 我的引用:
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>
<!--mapper-->
<dependency>
<groupId>tk.mybatis</groupId>
<artifactId>mapper-spring-boot-starter</artifactId>
<version>2.0.1</version>
</dependency>
<!--pagehelper-->
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<version>1.2.3</version>
</dependency>
我的配置: mybatis: type-aliases-package: com.*.entiry mapper-locations: classpath:mapper/.xml
mapper: mappers:
pagehelper: helperDialect: mysql reasonable: true supportMethodsArguments: true params: count=countSql
不管mappers 怎么配置,insert报错: org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error invoking SqlProvider method (tk.mybatis.mapper.provider.base.BaseInsertProvider.dynamicSQL).

有没有用 tk.xxxx.@MapperScan
注解?如果没有,就需要在接口上增加 @Mapper
接口。
在spring boot 1.5.2是可以正常用的,升级到spring boot 1.5.9之后,查询出错,于是升级mapper到1.2.4或2.0.1,查询不出错了,但是插入不能用mapper的insert方法,报了上面的错误。
如果用低版本,就配置 mapper.mappers 参数
