org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.sottop.sokonmobile.sokonmobile.qingdao.dao.mybaits.AsStmTechnologicalItemDao.getDictionary'. It's likely that neither a Result Type nor a Result Map was specified.

这个错误提示是因为 MyBatis 执行了一个查询语句，但是没有找到相应的结果映射。这通常是由于未指定查询语句的返回结果类型或者结果映射导致的。你可以检查一下对应的 Mapper XML 文件或者 Java 接口中是否正确指定了查询语句的返回结果类型或者结果映射。如果还有问题，可以提供更多的代码和错误信息以便更好地帮助你解决问题。

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement

这个异常通常发生在使用MyBatis进行数据库查询时，没有为映射语句（Mapped Statement）定义结果映射（Result Maps）。这意味着MyBatis无法将查询结果映射到目标对象上。

要解决这个问题，你需要确保为每个映射语句定义了正确的结果映射。结果映射可以通过XML映射文件或注解来定义。

如果你使用的是XML映射文件，你可以在映射文件中为相应的映射语句添加结果映射。例如：

<!-- 定义结果映射 -->
<resultMap id="myResultMap" type="com.example.MyObject">
    <id property="id" column="id" />
    <result property="name" column="name" />
    <!-- 其他属性映射 -->
</resultMap>

<!-- 映射语句 -->
<select id="myQuery" resultMap="myResultMap">
    SELECT id, name
    FROM my_table
    WHERE ...
</select>

如果你使用的是注解，你可以在相应的接口方法上使用`@Results`注解来定义结果映射。例如：

@Select("SELECT id, name FROM my_table WHERE ...")
@Results({
    @Result(property = "id", column = "id"),
    @Result(property = "name", column = "name"),
    // 其他属性映射
})
List<MyObject> myQuery();

请确保为每个映射语句定义了正确的结果映射，以便MyBatis能够正确地将查询结果映射到目标对象上。

nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.

nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
Error querying database. Cause: org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.example.mapper.UserMapper.getUserById'. It's likely that neither a Result Type nor a Result Map was specified.
Cause: org.apache.ibatis.executor.ExecutorException: A query was run and no Result Maps were found for the Mapped Statement 'com.example.mapper.UserMapper.getUserById'. It's likely that neither a Result Type nor a Result Map was specified.

This exception is thrown when there is an issue with executing a query using MyBatis framework. In this case, the nested exception is org.apache.ibatis.exceptions.PersistenceException, which indicates that there was an error querying the database.

The specific error message states that no Result Maps were found for the Mapped Statement 'com.example.mapper.UserMapper.getUserById'. This means that either a Result Type or a Result Map was not specified for the query.

To resolve this issue, you need to make sure that the appropriate Result Type or Result Map is specified for the query in the MyBatis mapping file (XML) or in the annotation-based configuration.
