也是一样的错误。

abel533 commented 6 years ago

mappers 参数错误导致的。升级到 2.0.1 或者配置 mappers 都能解决。

chenfromsz commented 6 years ago

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>

        <artifactId>pagehelper-spring-boot-starter</artifactId>

    </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。

chenfromsz commented 6 years ago

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。

abel533 commented 6 years ago

如果用低版本，就配置 mapper.mappers 参数
